Accelerated EMG Biofeedback Relaxation Training and Tension Headache: The Effects of Home Practice and Headache Presence During Training
This study investigated the value of headache presence during elecromyographic (EMG) feedback relaxation training and the contribution made by home relaxation practice in the elimination of tension headache. Eighteen participants, mainly coeds in their twenties, recorded headache and medication data for two baseline weeks, and were assigned to one of three training groups. Group A received EMG feedback training with headache presence during the session and home relaxation practice. Group B received EMG feedback without headache Presence and home practice. Group C received only home relaxation practice. Statistically significant treatment differences were not found, but declining trends of headache activity and medication use tend to support the efficacy of EMG training with headache presence.
Acculturation in African American College Women and Correlates of Eating Disorders
Although eating disorders have been the focus of much research, the inclusion of minority populations has been minimal. A recent review of the literature by Dolan (1991) has found that eating disorders were most likely to be present in non-White women who were exposed to Western societies and cultures. Thus, the purpose of this study was to examine personality, physical, and cultural correlates of bulimic symptomatology in a sample of African American college women. The Bulimia Test Revised (BULIT-R) was used to assess bulimia symptoms. The African American Acculturation Scale (AAAS), the Beliefs about Attractiveness Scale Revised (BAAR factors 1 and 2), the Rosenberg Self-Esteem Scale (SES), the Centers for Epidemiological Depression Scale (CES-D), Body Parts Satisfaction Scale (BPSS), and body mass were the independent variables hypothesized to predict bulimic symptoms. Hierarchical regression analysis revealed that body mass, depression, and low self-esteem were the best predictors of bulimic symptomatology, together accounting for 38% of the variance. Beliefs about attractiveness and body satisfaction were related to bulimic symptoms but not when considered simultaneously with the other variables. Acculturation was not predictive of bulimic symptoms. 0-ordered correlations revealed that beliefs about attractiveness and body satisfaction were correlated with bulimic symptoms. Acculturation was not related to any variables except depression. Implications for counseling interventions as well as directions for future research are discussed.
Analysis of Perceptions and Demographic Factors of Selected College Students' Vote in the 1972 Presidential Election
"The present investigation was concerned with college students' perceptions of candidates in the 1972 Presidential Election."--[1].
An Analysis of the Relationships of the Perceptions of College Environment by Existing Groups and Subgroups on the Campus of a Small Church-affiliated College
The CUES II was used to investigate and analyze the campus environment of a small church-affiliated college in California.
Assessment of Brain Damage: Discriminant Validity of a Neuropsychological Key Approach with the McCarron-Dial System
The present study investigates the predictive accuracy of a key approach to interpretation of the verbal-spatialcognitive (VSC) and sensorimotor (SM) factors of the McCarron-Dial System (MDS). The subjects include 99 brain damaged and 30 normal adults. The following research questions are addressed: (a) Does the neuropsychological key classify brain damaged and non-brain damaged subjects at a level significantly above chance? (b) Among the brain damaged subjects, does the neuropsychological key identify right brain damage, left brain damage and diffuse brain damage at an accuracy level significantly above chance? (c) Is the neuropsychological key approach superior to the empirical model derived from discriminant function analysis in predictive accuracy? The neuropsychological key correctly classifies 90% of the cases as brain damaged and 90% of the cases as non-brain damaged, for a total of 89.9% predictive accuracy. The obtained Kappa coefficient of .74 is statistically significant. The key accurately classifies 71.4% of the brain damaged group as right damage, 70% as left damage, and 93.8% as diffuse damage, for a total predictive accuracy of 7 9.5%. The Kappa coefficient of .68 is statistically significant. Chi square analysis of the difference between the key approach and multiple discriminant function analysis reveals that no significant difference is present between the accuracy of the two approaches in differentiating between brain damaged and non-brain damaged, or in differentiating among left, right and diffuse brain damage. The results support the validity of a neuropsychological key approach to interpretation of the McCarron-Dial System, although cross-validation is indicated to confirm the stability of these results. Differences in sex, educational level and racial composition of the comparison groups may have affected the results obtained. Refinement of the key in future research and the addition of test instruments assessing memory, auditory processing, attention and emotional/behavioral variables are recommended.
Attention and Information Processing Variables in Hypothetically Psychosis-Prone College Students
Considering the explanations of schizophrenia that presume schizophrenia spectrum disorders (e.g., schizotypal personality disorder, schizoaffective disorder, etc.) to be genetically related to schizophrenia, the purpose of this study was to investigate the attention and information processing abilities of individuals who have been identified as schizotypal or psychosis-prone (i.e., schizophrenia spectrum functioning in individuals who do not have schizophrenia). Research indicates that persons identified as psychosis-prone may show attention and information processing deficits similar to individuals with schizophrenia. The identification and description of individuals who later decompensate into schizophrenia would advance the understanding of schizophrenia and its causes. The Chapman's PER-MAG scale (Perceptual Aberration-Magical Ideation) was used to identify 35 hypothetically psychosis-prone college students (schizotypy group) and 42 normal college students (nonschizotypy group) out of the 806 volunteer subjects. Their attention and information processing abilities were measured by COGLAB (a multiparadigmatic cognitive test battery that represents a continuum of cognitive functions, from preattentional to attentional, to conceptual). Their social adjustment was measured by the Premorbid Adjustment Scale (PAS). The hypotheses of the study were that the hypothetically psychosis-prone subjects would perform poorer than controls on COGLAB measures and that COGLAB measures of a more molar nature would better predict social adjustment than would the more molecular tasks. The results of the study did not support the hypotheses as there were no significant differences between the schizotypy group and the nonschizotypy group and the measures of a more molar nature did not better predict social adjustment. Further research might consider increasing the sample size, applying more stringent cut-off criteria for the schizotypy group, and verifying the validity of using PER-MAG, COGLAB, and PAS with this population. Further research also needs to clarify the ways in which those identified as psychosis-prone process information like (or unlike) nonschizotypes and how their current social functioning might be related to their deficiencies.
Attitudes Toward Psychodiagnostic Testing and Doctoral Clinical Psychology Students' Professional Expectations and Training
Responses of 111 doctoral clinical psychology students to Garfield and Kurtz' (1973) Testing Attitude Scale were subjected to a 2 x 2 factorial analysis. Attitudes toward psychodiagnostic testing were found to be related both to academic versus nonacademic professional expectations (academics scoring more negatively, M = 32.69, than nonacademics, M = 37.19), F (1, 107) = 5.994, p < 0.016, and to internship training exposure (non-interns scoring more negatively, M = 34.64, than interns, M = 38.80), F (1, 107) = 10.321, p< 0.002. Results paralleled previous research on academic and nonacademic working psychologists' attitudes. Similarities in students' and role models' attitudes were discussed in terms of Kelman's (1953; 1958), Festinger's (1957), and Bem's (1970) attitude theories. Results seemed to imply continued controversy over both the desirability of producing psychodiagnostically oriented clinicians, and also traditional paradigms of psychodiagnostic training.
Behavior Rehearsal Combined with Anxiety Relief Conditioning : A New Assertion Training Paradigm and Its Relative Efficacy
An experiment was conducted to investigate the relative effectiveness of a combined behavior rehearsal anxiety relief conditioning paradigm with a more conventional behavioral rehearsal program in the treatment of deficient assertive behavior.
Beliefs of Internal Versus External Control and Their Relationship to Stage of Moral Judgment
This investigation sought to explore the relationship of Julian Rotter's concept of internal versus external control (I-E) to stages of moral judgment. The I-E dimension is defined as the attribution by the individual of responsibility for behavioral outcomes to either oneself or to outside entities. The internal oriented person believes that the events in which he is involved lie within his control. Conversely, the external oriented person believes that the events that happen to him are controlled by other factors.
Birth Order and Parent-Child Relations
The purpose of this study was to investigate the birth order differences in perception of parental child-rearing practices in one-and two-sibling families. The two-sibling families were separated into all the possible sex permutations (male-male, female-female, male-female, female-male) to assess the influence of sex of sibling in viewing the parents' child-rearing practices.
Brain Dysfunction Indication on the Bender-Gestalt Test: a Validation of the Embree/Butler Scoring System
The Embree/Butler scoring system served as criterion for ascertaining brain dysfunction on the protocols of 100 subjects--50 had been diagnosed by health professionals as having brain dysfunction, and 50 had been diagnosed as having no brain dysfunction. In comparing the hospital's diagnoses with those of the Embree/Butler method, the data strongly supported the hypothesis that the Embree/Butler scoring system did effectively discriminate (chi square of 77.99 < .01) between those with organic brain syndrome (or cerebral dysfunction) and those with psychiatric classification. A point-biserial correlation was used to distinguish the relationship between diagnosis and the score. A cutoff score of above 14 produced the least false-negative or false-positive evaluations.
Career Counseling with Academically Talented Students
Academically talented college students have unique development needs that often go unmet. One area that is currently attracting more attention in the academically talented literature is career counseling. The purpose of the present study was to compare the effectiveness of individual and group career counseling interventions. Subjects included 54 students from a special Texas program that provides the opportunity for gifted students to attend college during their final two years of high school. One instrument used assessed identity, confidence, career goals, and professional identity. The second instrument evaluated whether the subjects had recently discussed career concerns, were seeing a vocational counselor, or seeking career information. A pre-test was followed by group or individual intervention, and a post-test was conducted two months later. Results indicated an overall decrease on the instrument assessing professional identity and career goals. This study revealed no difference in effectiveness between group or individual interventions. Further research in this area is necessary to develop and refine the most effective career counseling interventions for the academically talented student.
Clinical Correlates of the Minnesota Multiphasic Personality Inventory - Adolescent (MMPI-A) for a Male Delinquent Population
The Minnesota Multiphasic Personality Inventory (MMPI) was one of the most widely used psychological tests administered to adolescents. The MMPI-A is a revised version of the MMPI that was developed specifically for adolescents. The purpose of this study is to establish clinical correlates for the MMPI-A standard scale codetypes.
Coacting Group Effects of Learning and Performance across Anxiety Levels
The problem with which this study is concerned is that of determining the effects of coacting groups and test anxiety on the learning and performing abilities of children. The purpose of this study is to investigate the effects of small coacting groups and test anxiety on specific "performance" and "learning" tasks. This study also provides a direct test of Zajonc's theory.
The Cognitive and Emotional Correlates of Neglect in School Age Children
The purpose of this study was to examine the cognitive and emotional functioning of neglected, physically abused, and clinical control children between six and thirteen years of age who were referred for testing at the Dallas Child Guidance Clinic.
College Students at Risk of Academic Failure: Neurocognitive Strengths and Weaknesses
This study examined the neurocognitive skills, incidence of mild head injury, incidence of learning disabilities, and study habits among college students with grade point average of 2.00 or below (N = 25) as contrasted with college students with grade point average above 2.00 (N = 70). The intent of this research was to extend the work of Segalowitz and Brown (1991) and Segalowitz and Lawson (1993) who found significant associations between reported history of mild head injury and developmental disabilities among high school and college samples. MANOVAs conducted on measures of academic achievement, global cognitive skills, verbal and nonverbal memory, motor and tactile functioning, and study habits did not discriminate between probationary and non-probationary students. Probationary and non-probationary students also did not differ with regard to incidence of reported head injury, frequency of diagnosed learning disabilities, and study habits. Measures of neurocognitive functioning and study habits did not contribute to the prediction of grade point average over and above that predicted by Scholastic Aptitude Test composite score. Several exploratory analyses were performed examining the relationship between study habits and neurocognitive skills. Gender differences, implications for future research and development of study skills courses, and limitations of this study were discussed.
The Comparative Effectiveness of Behavior Rehearsal and Systematic Desensitization in the Treatment of Social Anxiety
The present study was concerned with comparing the relative effectiveness of behavior rehearsal and systematic desensitization in the treatment of social anxiety.
Comparing Quality of Life: American and Portuguese Cancer Patients with Hematological Malignancies
The purpose of this study is to investigate the differences and similarities of quality of life (QoL) in American and Portuguese cancer patients with hematological malignancies as well as the robustness of the measures cross-culturally. Portuguese participants were 98 patients and 49 accompanying persons and the American participants were 55 patients and 22 accompanying persons. Fifty (Portuguese sample) to 40% (American sample) of the patients came with an accompanying person who answered the questionnaire concerning the patient's QoL. The two cultural groups were characterized in terms of QoL (measured by the SF-36 and the FLIC), social support (Social Support Scale), socio-demographic and clinical variables. Portuguese patients reported a higher QoL. However, this result could be attributable to the fact that the two cultural samples differ in socio-economic status. The measures seem to be comparable for the Portuguese and American samples, at least in what concerns reliability and concurrent validity.
A Comparison between the Self-concept of Visually-impaired Adults and Sighted Adults
Self-concept scores of 19 visually-impaired adults were compared to those of 19 matched sighted adults using the Tennessee Self-Concept Scale (TSCS). All participants attended the University of North Texas. Scores were examined against the Vocabulary and Information subtests of the Wechsler Adult Intelligence Scale-Revised (WAIS-R).
A Comparison of Delinquents and Nondelinquents Using the IES Test
Many of the causes for delinquency are known, but more investigation is needed in the prediction of future delinquent behavior. It was in this area of delinquency that this study was concerned. The problem was to compare scores made on the IES Test by a group of nondelinquent males with those made by a group of delinquent males to determine if the IES Test would discriminate between these two groups.
A Comparison of Empathic Ability between Business and Psychology Majors
This study was undertaken in the belief that students of psychology possess a significantly greater degree of empathic ability than do students of other college majors. The purpose of this study was to determine whether there is any significant difference in empathic ability between psychology students and business students as a group.
Comparison of Group and Individual Methods of Presenting Baldwin's Social Expectations Scale
Forty Ss from introductory psychology classes participated in a study to determine whether or not the investigator's group Social Expectations Scale (SES) was a useful research instrument and to determine whether or not intelligence was a factor determining the fit of a particular cognitive model, the BSE, to the social expectations of Ss as measured by the SES.
A Comparison of Performance and Levels of Aspiration of High and Low Anxious Males and Females
The present study was concerned with the relationship between level of aspiration and anxiety. Level of aspiration is a term used for goal setting behavior. In other words, if a person sets his goals high it is said that he has a high level of aspiration. Anxiety, for the purpose of the present study is assumed to possess drive properties. Theoretically, at least, a highly anxious person has a high drive level. This assumption may be warranted in terms of physiological unrest--causing an effort toward equilibrium or homeostasis; or it can be defended psychologically as the need to achieve or the need to prove one's abilities to himself. However, the present paper was not concerned directly with the current controversy of anxiety as a drive mechanism. Rather it was the general purpose of the study to determine whether or not highly anxious college students set their goals higher, in response to previous experimental success or failure experiences than low anxious students. To be more specific the purpose was to determine whether or not highly anxious subjects differ significantly from low anxious subjects with respect to responses on a level of aspiration task. The particular response measures or scores investigated on the level of aspiration task were those shown between performance on one trial and the stated hoped-for- score, expected score, and the minimal-acceptable-score on the succeeding trial.
A Comparison of Physics and Psychology Majors on FIRO-B Variables
It is the basic assumption of this study that a relationship exists between the interpersonal needs of inclusion, control, and affection and occupational choice as indicated by college major. Studies in the area of vocational choice have largely dealt with people who are practicing the vocation, leaving doubt as to whether people are attracted to the vocation as a result of need-satisfaction behavior, or whether the people determine their orientation by practicing the occupation. The need for further clarification of these questions was recognized, and this study was an effort to add to the evidence for or against the validity of the concept of interpersonal need satisfaction as a factor in vocational choice.
A Comparison of Sight Word and Phonics Contingencies in the Remediation of Oral Reading and Comprehension
A comparison of contingent word and phonics drilling exercises on oral reading errors was made and the effects of a work skipping contingency on reading comprehension were examined. Five learning disabled elementary school children served as subjects. Reading comprehension increased from 30 to 50% over baseline, while subjects progressed an average of two years through a reading series. Subjects responded differentially to the two drills on oral reading errors, but the combined effects of the drills produced a 50% average reduction in errors. Pre- and post-tests of reading achievement showed increases in reading grade levels ranging from .8 to 1.5 years during the 10 week, 30 session study. Results supported the efficacy of a behavioral approach to reading remediation.
A Comparison of the Relative Ego Strengths of Two Prison Groups and a Non-Prison Group as Measured by the IES Test
This study was concerned with the differences between two types of prisoners on a personality dimension and differences between these prison groups an a non-prison population. The impetus for this study stemmed from the development of a new test designed to scientifically measure the Freudian concept of the personality structures, the id, ego, and superego.
Congruence of Multi-level Perceptions Over the Length of Marriage and Marital Adjustment in Air Force Couples
Spousal congruence at multiple levels of perception was examined in relationship to marital adjustment. Subjects were 164 active duty and retired Air Force married couples.
The Consequences of Labeling a Person as Mentally Ill in an Urban Black Community
This study has a twofold purpose. The first is to determine the consequences related to labeling deviant behaviors, especially as these effects are reflected in the person who labels and defines deviant behavior. The second is to evaluate the medical model of abnormality in relation to the labeling of deviant behavior.
A Construct Validation Study of the Personality Inventory for Youth (PIY) Using an Incarcerated Juvenile Population
The Personality Inventory for Youth (PIY) is a recently developed, multiscale assessment instrument designed specifically for adolescents between the ages of nine and 18. The purpose of this archival study was to establish clinical correlates for the PIY scales. PIY profiles were collected from 100 juvenile files at the Gainesville State School and examined in conjunction with the Child Assessment Scale (CAS) and the Personal Attitude Scale (PAS) to provide evidence of convergent and discriminant validity. Results indicate modest to moderate convergent validity according to Campbell and Fiske's criteria for construct validity; however, discriminant results indicate considerable overlap among traits which are not expected to be highly correlated.
A Continuation in the Defining of the Construct of Optimism
One hundred twenty-two undergraduate students at the University of North Texas were administered several different optimism scales and also measures of similar constructs such as hope. Results indicated that most measures of optimism show only low to moderate intercorrelations with other measures of the same construct. Additionally, factor analysis confirmed that the measures of optimism actually appear to be assessing multiple factors and not necessarily optimism alone. Implications of the present study include the necessity of individual researchers to be familiar with the specific measure of optimism used in a given study as scores on differing measures of optimism may actually be providing very different information.
Control, Commitment, and Challenge: Relationships to Stress, Illness, and Gender
Male and female college students were administered scales assessing their daily hassles, negative life events, control, commitment, challenge, psychological symptomatology, psychological distress, and physical symptomatology. Stepwise multiple regression analyses showed that control, commitment, and challenge act in an additive (rather than multiplicative) manner in relation to psychological and physical outcome measures.
Coping with Severe, Acute Psychological Trauma: the Killeen Shooting Incident
The present study examined the relationship between coping and psychological and psychosomatic distress of 25 individuals who experienced the same severe, acute traumatic event: the violent shooting that killed 23 people and severely injured 20 more in Luby's Cafeteria in Killeen, Texas, on October 16, 1991. Distress was assessed by one-month pre-event and post-event scores on the SCL-90R, Psychosomatic Questionnaire, and by a Life Event Questionnaire score for the year before the incident. Coping was measured by a modified version of the Ways of Coping Scale (Folkman et al., 1986) and Response Style Questionnaire (Nolen-Hoeksema & Morrow, 1991). All post-event distress scores, except the Psychosomatic score, significantly increased over their corresponding pre-event scores regardless of gender. Although female distress scores were consistently higher than male scores, gender was predictive of post-event distress only for the SCL-90R Anxiety, Somatization, and Global Severity Index scales. The only pre-event score found to be predictive of post-event distress was the Psychosomatic scale. Regression analysis, with demographic and pre-event variables controlled, found a significant positive relationship between Escape/Avoidance coping and one-month post-event levels of Anxiety and Psychosomatic distress. Findings were discussed in the context of the process-oriented stress-illness model and were compared to current disaster and crime victimization literature. Implications for helping professionals, methodological issues, and implications for future research were explored.
Correlational Study of the UNT Neuropsych-Screen, the MMPI and Time among Chronic Pain Patients
Although many theorists have speculated that chronic pain may be linked to some sort of central neuropsychological integration deficit, a review of the current literature reveals no empirical support for this theory. This study attempts to assess the severity, if any, of neuropsychological deficits in chronic pain subjects by using a neuropsychological screen developed at the University of North Texas. Also, presented are studies of correlations between the UNT Neuropsych-screen and the MMPI. the Dallas Pain Questionnaire (DPQ), the Dallas Pain Drawing CDPD), and time since injury in order to assess any possible relationships. The subjects in this study consist of 100 volunteers. Of these subjects, 74 were patients of the Spinal and Chronic Pain Center at Medical Arts Hospital in Dallas, Texas and represented the clinical population. The remaining 26 subjects were staff volunteers from the hospital . The results of the study indicate significant differences between chronic pain subjects and non-pain subjects across many areas of neuropsychological functioning, as well as other significant correlations among many of the variables. The implications of this study are elaborated upon, in the discussion section, in detail along with limitations and future research directions.
Criterion Validity of the MMPI-2 in a State Hospital Setting
The current study investigated the criterion validity of the Minnesota Multiphasic Personality Inventory - 2 (MMPI-2) by comparing participants' profiles with other variables, including diagnosis, length of hospitalization, and chronicity. The specific diagnostic groups investigated were depressed (major depressive disorder; dysthymic disorder; and bipolar disorder, depressed), schizophrenic (schizophrenia, schizophreniform disorder, and schizoaffective disorder), and borderline personality disorder (BPD). Statistical analyses included use of univariate analyses of variance (ANOVAs), multivariate analyses of variance (MANOVAs), regression analyses, and measures of sensitivity, specificity, positive predictive power (PPP), and negative predictive power (NPP). MANOVA results indicated significant differences between diagnostic groups on Scales F, 2, 3, 4, 7, ANX. FRS. DEP. BIZ. M f i , LSE, and FAM. There were considerable differences between males and females when separate MANOVAs were performed for gender groups. Cutoff see ires for classification by diagnosis resulted in significant specificity rates and negative predictive power, but sensitivity rates and positive predictive power were not significant.
Cue-Controlled Relaxation: Saving Time Versus Efficacy
Cue-controlled relaxation is looked at to determine whether a component is efficacious as the entire procedure. Subjects were 40 male and 40 female undergraduates. Subjects were randomly assigned to one of four conditions: cue-controlled relaxation, progressive muscle relaxation, breathing exercises with a paired. cue word, on a presentation of the cue word without being paired. It was hypothesized that cue-controlled relaxation would be superior to a component of cue-controlled relaxation. It was determined that cue-controlled relaxation is not more efficacious than a particular component. Data suggests the majority of anxiety reduction takes place when the treatment focuses on the same modality from which the subject receives the most information about their anxiety. Implications and suggestions for further research are presented.
Cultural Differences in Pain Experience and Behavior among Mexican, Mexican American and Anglo American Headache Pain Sufferers
Review of previous research on cultural differences in pain experience and/or pain behavior revealed that cultural affiliation affects pain perception and response. Unfortunately, the many inconsistent findings in the literature on cultural differences in pain experience and behavior have made interpretations and comparisons of results problematic. These inconsistent findings could be attributed to variations in acculturation level among cultural groups. The purpose of this study was to investigate cultural differences in pain experience (assessed by McGill Pain Questionnaire, the Box Scale, the Headache Pain Drawing, and the Headache Questionnaire) and pain behavior (measured by determining medication use and interference of daily functioning due to headaches) among Mexican (n = 43), Mexican American (n = 36), and Anglo American (n = 50) female chronic headache pain sufferers. The contribution of acculturation to differences in pain experience and behavior among cultural groups was measured by the Acculturation Rating Scale for Mexican Americans. The three cultural groups of women significantly differed on pain experience and pain behavior. Specifically, Mexican women experienced their headache pain more intensely, severely, and emotionally than Mexican American and Anglo American women. Furthermore, Mexican women were more willing to verbally express their pain than the other two groups. As for pain behavior, Mexican women took more medication and reported more severe inhibition of daily activities due to headaches than Mexican American and Anglo American women. Ethnic identity, ethnic pride, and language preference were factors in the acculturation process which contributed the most to women's chronic pain experience and behavior. The greatest variability occurred within the Mexican American group of women who perceived themselves as being more Mexican in attitudes and/or behaviors, but more similar to Anglo American in their pain experience and pain behavior. Results are explained using biocultural multidimensional pain theory, social learning theory, and acculturation theory.
Deep Muscle Relaxation Obtained with Analog Electromyographic Information Feedback
The purpose of the research study was to provide improved relaxation training with the use of an electromyography feedback device based on the design of Green et al. (1969). It was intended that this instrument would allow the training of deep muscle relaxation to the point of neuro-muscular silence, while remaining inexpensive enough to be applied in the clinical setting.
Depression and Heart Rate Variability in Patients with Coronary Artery Disease
Depression is an independent risk factor for morbidity and mortality in patients with coronary artery disease (CAD). Altered autonomic nervous system (ANS) activity, a common feature of depression, is also a risk factor for cardiac events in patients with CAD. Heart rate variability (HRV) reflects ANS activity, and reduced HRV predicts morbidity in cardiac populations. The purpose of this study was to determine whether differences in HRV exist between depressed and nondepressed patients with CAD. Twenty-one depressed inpatients, with angiographically documented CAD were retrospectively matched to 21 nondepressed CAD patients by sex, age, and smoking status. Demographic, medical, psychological interview data, and 24-hour ECG recordings were obtained. Depressed subjects had significantly lower HRV, or trends toward lower HRV, than nondepressed subjects, even after controlling for severity of CAD. Subject groups did not differ on left ventricular ejection fraction, history of myocardial infarction, or any other relevant medical variable assessed. These results suggest that depression is associated with decreased HRV in patients with CAD, and may help to explain the increased rates of cardiac events observed in CAD patients with depression.
Development of an Instrument for Evaluation of a Management Education Program
This study was designed to develop a rating instrument to measure the effectiveness of the first phase of management education for an Air Force officer, An officer's ability to lead, the first objective of management training, is intrinsically related to the ability to write, speak, and solve problems. These were behaviorally stated in a 60 item survey. Supervisors (N = 174) were asked to rate the frequency of occurrence of these behaviors for a subordinate. The survey was administered on two occasions to supervisors of officers eligible for training. Item analysis of the results reflected a strong favorable response bias with usable variability. Data indicated the instrument was a unidimensional internally consistent scale.
Diabetes Status of Mexican Americans: Impact of Country of Birth
In order to better tailor treatment to specific populations, factors which contribute to health disparities among different racial/ethnic groups must be examined. Among Mexican American individuals, the high rate of diabetes represents a significant contributor to overall health. The present study focuses on factors affecting diabetes status among Mexican Americans born in either Mexico or the United States using the 2007 – 2008 NHANES data set. Comparisons were made between diabetes status based on self-report and clinical classification using HbA1c. Results indicated that within the diabetic subsample, Mexican Americans born in Mexico were twice as likely to be incorrectly classified as non-diabetic, when they actually were diabetic, when using a self-report method. In contrast, nativity did not result in differences in diabetes incidence using the HbA1c clinical cut-score diagnostic classification. Age, BMI, gender, nativity, and health insurance coverage were found to have varying relationships to diabetes prevalence and HbA1c levels, but time in the U.S. for Mexico-born individuals was not found to uniquely predict diabetes incidence. Analyses also demonstrated that Mexico-born males, as compared to the other groups, had significantly higher HbA1c levels. Further research is necessary to better understand the relationships among these factors. However, findings do demonstrate a need for more objective disease classification, particularly when examining immigration status and diabetes. Additionally, the complexity of these interactions establishes a need for specific health intervention for foreign-born populations which might be missed by self-report screening asking about presence of disease and exacerbated by an oversimplification of the “healthy immigrant effect”.
Dogmatism and Sex Role Differentiation in Adults
This study is an investigation of the general questions Is there a relationship or interaction between a subject's dogmatism score (as measured by the Dogmatism Scale) and his self-rating of the perceived stereotypical masculinity-femininity dimension (as measured by the abridged Mf scale of the Minnesota Multiphasic Personality Inventory)?
Early Recognition of Minimal Brain Injury through Use of the Metropolitan Readiness Tests
This study explored the usefulness of the Metropolitan Readiness Tests (MRT) as a screening device for minimal brain injury. It was hypothesized that brain injured (BI) children would score significantly lower on Test Six of the MRT than non-brain injured (NBI) children. Test Six is a visual-motor perceptual task.
Educable Mentally Retarded: Classification of Students and Texas State Guidelines
In Texas, placement of educable mentally retarded (EMR) students has required three factors-- intellectual assessment, educational appraisal, and adaptive behavior. This study examined 28 reclassified EMR students to determine which assessment factor is least stable in defining EMR and to determine significance of change in assessment scores. Data were secured from school records. Type of intellectual assessment test used varied greatly and was found to be the most inconsistent placement factor. However, educational appraisal scores contributed to over half the reclassifications. Adaptive behavior did not contribute to any reclassification. Due to limited sampling and variety of assessment tests, significance of change in scores was not determined. Generally, on retest,performance IQ scores were elevated while verbal IQ scores remained the same.
The Effect of Meaningfulness, Position, and Overlearning on Selective Stimulus Encoding in Paired-Associate Learning
The present experiment was an attempt to study to joint effects of stimulus component meaningfulness, positional cues, and overlearning upon cue selection in recall and, additionally, to test the stimulus component independence hypothesis advanced by Wichawut and Martin (1970).
The Effect of Memory Requirement on Schema Learning
A number of previous investigations have suggested that schema learning would be more readily facilitated by a recognition task than a reproduction task due to the increased memory requirement of the reproduction task. Differential memory requirements of 0, 4, 8, 16 and 32 seconds were imposed on 50 Ss in a recognition task to determine if increased memory requirements improved schema learning in the same mode as the reproduction task. The results indicated no significant improvement in schema learning with increased memory requirement. The data does suggest negative transfer from reproduction to recognition task. Recommendations for design and procedural improvements are included.
The Effect of Monetary Reward and Knowledge of Results on Complex-Choice Reaction Times
This investigation was designed to determine relative effects of monetary reward and knowledge of results on complex-choice reaction time tasks. Subjects were twenty-five male and thirty-two female undergraduate students. Apparatus consisted of nine stimulus lights and eight response keys. Subjects were required to add the number of lights presented, subtract the sum from a constant, and press the correctly numbered response key. Reward subjects received twenty-five cents for responses faster than a predetermined criterion, and twenty-five cents was deducted for slower responses. Knowledge of results subjects were told their reaction times after each trial. Results indicated (1) no significant differences between any conditions, (2) a significant overall practice effect (.01 level), and (3) that males were significantly faster than females (.01 level).
The Effect of Scheduling on College Achievement
This investigation is concerned with the problem of determining the variation of test achievement obtained by students enrolled on a MWF and a TTh schedule. The purpose of the study is to determine if either schedule is superior. The Ss were students enrolled in an Introductory Psychology course at North Texas State University. A t test was administered to the experimental data. The experimental hypothesis of an expected higher test achievement by students enrolled in the TTh schedule was rejected. It was concluded that test achievement for this study was not affected by scheduling.
The Effects of a Natural Disaster on Academic Abilities and Social Behavior of School Children
Although most research has focused on adults, studies indicate that children also experience detrimental psychological effects as the result of natural disasters. The purpose of the present study was to determine if the tornado which struck Wichita Falls,, Texas, on April 10, 1979, had any negative effects on the academic performance or social behavior of school children. Three groups of students were studied: (a) victims of the tornado who suffered a significant loss, (b) observers of the disaster who did not suffer a significant loss, and (c) newcomers who arrived after the disaster. Achievement test scores, grades, and attendance over a 4-year period were studied. The overall results do not indicate significant differences among the three groups.
