Effects of Experimental Psychological Stress on Human Physiological Functioning: Mediation by Affiliation

Description: This investigation sought to identify differences in the human psychophysiological stress response when mediated by affiliation, by assessing heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), electrodermal activity (EDA), serum Cortisol (SC) concentration, interleukin-2 (IL-2) concentration, and state anxiety among subjects who underwent an anagram solution task. Thirty male subjects from the University of North Texas were randomly assigned to one of two experimental conditions and asked to solve a series of difficult anagrams either alone or with a companion. Subjects assigned to the control condition were asked to copy permutations of the anagrams. Before, and immediately after the anagram/copying tasks HR, SBP, DBP were measured, blood samples drawn, and The State-Trait Anxiety Inventory (STAI) administered to all subjects. EDA was measured throughout all trials. Changes from baseline through the experimental period for all dependent variables were analyzed by employing difference scores derived from contrasting baseline and experimental measures. These scores were subjected to an analysis of variance (ANOVA) resulting in one significant between group effect among all dependent variables examined. Contrary to stated hypotheses, the alone condition significantly differed from the companion and control conditions by demonstrating a significant decrease in systolic blood pressure from baseline through the experimental period. It was concluded that the decrease in systolic blood pressure from baseline through the experimental period for the alone group was a result of chance sampling of individuals possessing unique psychophysiological response patterns. Appraisals of inter-group differences in response patterns across all dependent variables suggest that an insufficient stressor, and limitations in design, statistical analysis, and measurement may have contributed to this investigation's results. Implications of findings were discussed along with suggestions for future research.

The Relationship of Stress, Cognitive Appraisal and Dating Violence

Description: The purpose of the present study was to test a specific path model. It was hypothesized that the relationship between the impact (amount and valence) of stress and an outcome (expressing violence toward a partner) would be mediated by an individual's cognitive appraisal of stressful events. Multiple regression procedures were used to test the model. Standardized beta coefficients indicated the strength of the relationships among the variables. Significant findings indicated that the strength of specific relationships among the ten variables (impact of events, three types of primary appraisal, four types of secondary appraisal and the expression of threats and acts of physical violence toward a partner) differed depending upon subject sex and whether the impact of the events was perceived as positive or negative.

Control, Commitment, and Challenge: Relationships to Stress, Illness, and Gender

Description: 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.

Individual Differences in Stress-Reactivity and the Influence of Self-Complexity on Coping Behaviour

Description: The influence of self-complexity on coping behaviour and emotional adjustment is explored. The Role Construct Repertory Grid (REPGrid) Community of Selves procedure is used to assess self-complexity. Following a structured interview format, subjects completed a battery of measures including the REPGrid, Self-Rating Depression Scale, Hassles Scale, Major Stress Scale, and Coping Index. Results indicate that complex individuals utilize a wider variety of coping behaviours than less complex individuals, although the perceived severity of stressful events was. no different between groups. Micro-analyses at the individual self level revealed mixed or null results. Finally, more dysphoric individuals reported using more negative coping behaviours (drinking, smoking) than individuals not experiencing dysphoric mood. Findings are discussed a) in terms of the utility of the REPgrid in the assessment and understanding of self-complexity and its' relationship to mental health processes, b) in accordance with a person-event transactional model of health and illness, and c) in terms of the relevance to those psychotherapies that emphasize and encourage people to develop distinctions among their self-aspects, as well as new ways of construing the world, and new behavioural options, e.g. Fixed Role Therapy.

The Effects of Biofeedback on Task Performance

Description: This experiment attempted to study the effectiveness of biofeedback training on an individual's peak performance while performing a stress-provoking task. In a between subjects design 30 individual college students were divided into 2 groups. One group received auditory biofeedback and relaxation training, and the other group received no training. Both groups met the researcher for 1 hour a week for seven weeks. During each session the participant completed a ten-minute Competition and Coaction (C & C) computer software program (Shea, 1992). The biofeedback equipment recorded the physiological state of each of the participants while he/she performed the C & C task. Both groups' physiological values and C & C scores were compared using the SPSS software. The biofeedback group had statistically lower stress values than the non-biofeedback group (Schwartz, 1995). There was no statistical difference between the 2 groups' C & C scores. The STAI Y-1 and Y-2 anxiety inventories were given to each of the participants at the 1st and 7th session to examine the anxiety differences between the 2 groups. There were no statistical differences between the 2 groups' STAI scores. This study's findings show that individuals can be taught to lower their stress response while performing a computer task.

Life Stress and Adjustment Effects of Cognitive Content and Cognitive Organization

Description: Individual differences of cognitive organization and content were investigated as they relate to adaptation to remote, recent, and immediate life stress. Outside the field of stress, prior researchers have implicated cognitive organization with adjustment and cognitive content with specific psychopathology. As for behavioral adaptation to life stress, cognitive organization was viewed as a major factor in emotional vulnerability and adjustment, and cognitive content as a major factor in the mood disturbance of depression. Behavioral adaptation was defined in terms of current emotional vulnerability, adjustment and negative changes in the immediate (last six months), recent (over six months), and remote (over one year) past.

The Effectiveness of a Stress Reduction Program for Police Officers

Description: A group of veteran police officers was studied in relation to the effectiveness of a stress reduction program which utilized a cognitive-behavioral approachto training. A new instrument, the Coulson Police Job Stress Discussionaire, (CPJSD), was field tested. Two control groups, a veteran group who received no stress reduction training and an academy group which received standard basic training but not the stress reduction program, were compared on pre—test and post-test Profile of Mood States (POMS) mood disturbance cores. Contrary to the main hypothesis formulated, there were no significant differences found between the three groups on post-test POMS measures of mood disturbance when compared with pre-test measures. The construct validity of the POMS for use with police officers is challenged. The specific format utilized is discussed and suggestions are offered for future study design. Specific difficulties inherent in the study of police groups are examined. The usefulness of the CPJSD for police job stress reduction program is suggested, as is the need for further field testing of this instrument.

Single and Married Mothers: A Comparison of Parenting Stress, Parenting Skills, and Self-Esteem

Description: This study compared divorced custodial mothers and mothers married to the biological fathers of their children on parenting stress, parenting skills, and self-esteem. The relationship between parenting stress, parenting skills, self-esteem, marital status, and life satisfaction was also examined. A total of 63 subjects, including 31 married mothers and 32 single mothers, was administered the Parenting Stress Index, the Parenting Skills Inventory, and the Tennessee Self-Concept Scale. Subjects also completed a Demographic Data Sheet that included a Likert-type scale designed by the researcher to measure current life satisfaction. All subjects either attended church or lived in a geographic area of North Central Texas that is generally recognized as being somewhat affluent. No significant differences were found on the t-tests comparing the mean total scores of the married and divorced mothers on levels of parenting stress, parenting skills, and self-esteem. A post hoc t-test revealed, however, that the group of married mothers had significantly higher mean total scores on the life satisfaction measure than the group of divorced mothers. Additionally, life satisfaction was found to be associated with parenting stress, parenting skills, self-esteem, and marital status. Specificallly, (a) as parenting stress increases, life satisfaction decreases, (b) as parenting skills increase, life satisfaction increases, (c) as self-esteem increases, life satisfaction increases, and (d) being married is associated with increased life satisfaction. The results of this study would seem to indicate that single mothers have no more difficulty in overall coping than their married counterparts although they are less satisfied with their current life circumstances than the group of married mothers. Additional comparisons of the data suggested that neither group of mothers regarded their children as interfering with their social lives in a major way. Like most previous research, the data also indicated that the single mothers worked longer hours and had less ...

Chronically Ill Children: Maternal Stress and Psychological Symptomatology

Description: This study used a parenting stress and coping model to identify predictors of symptomatology for 13 8 mothers of medically compromised children. This model proposed that: child characteristics (severity of the chronic illness and child related parenting stressors); parent characteristics (self-esteem, sense of competence, and parents' perceived stress/distress); and environmental characteristics (social support, general life stressor events, and demographic variables) contribute to psychological symptomatology for these mothers. Multiple regression analysis found a relationship between general life stressor events, severity of the children's chronic conditions, lower satisfaction with social support, lower self-esteem, and younger mothers' ages and greater symptomatology. Trends toward significance were found for more parenting stress and lower parenting sense of competence predicting greater symptomatology. Predicted relationships between family socioeconomic status and parenting daily hassles and symptomatology were not supported.

A Comparison of Academic Stress Experienced by Students at an Urban Community College and an Urban University

Description: The present study compared the academic stress levels of 450 college sophomore students at a public university and a public two-year college. This investigation also explored the levels of academic stress by institutional type, age, gender, and ethnicity. Data were obtained from having the subjects complete the Academic Stress Scale, a questionnaire which lists thirty five stress items found in the college classroom. Analysis of variance and t-tests were used to analyze the data. There were 225 subjects each in the community college group and the university group. The university group had a statistically significant higher mean stress score than the community college group. 294 traditional age (23 and younger) and 156 nontraditional age (24 and over) subjects stress levels were compared. It was found that the traditional age college student group experienced a statistically significant higher academic stress level in both academic settings. Group means were compared between the stress scores of 245 female and 205 male subjects. At both the community college and university levels, the female group had a statistically significant higher level of academic stress. The academic stress levels were also compared according to ethnicity. The minority group consisted of 104 subjects and 346 subjects comprised the non-minority group. At the community college, the minority group had a statistically significant higher level of academic stress. However, at the university level, there was no statistically significant difference by ethnicity. Examinations, final grades, term papers, homework, and studying for examinations were ranked as being stressful by the largest percentage of all the subjects. It was found in this study that levels of academic stress differ significantly by institutional type, age, gender, and ethnicity. Implications for college students, instructors, and administrators , based on this study's conclusions, are offered.

Life Stress and Industrial Accidents

Description: Traditional personality research on accident behavior has produced conflicting opinions as to the traits that describe the "accident-prone" personality type. Other research has shown that psychosocial life stress, while partially determining the temporal onset of a variety of illnesses, may also be a factor contributing to increased accident liability. This study examined the role of temporary and stress-producing life changes in groups of accident-free and accident-involved industrial employees. The accident sample was found to have significantly higher stress over baseline during the period of accident involvement, but generally lower pre-accident levels than the non-accident sample. A cause-effect analysis of the data from within the accident-involved sample proved inconclusive. Several implications for future research and managerial actions to alleviate stress were also discussed.

Stress Level, Background Variables, Premorbid Health Ratings, and Severity of Psychological Disorders Using DSM-III-R Ratings

Description: This study predicted that individuals diagnosed as having higher levels of stress, based upon DSM-III-R, Axis IV ratings, would also be diagnosed as having more severe forms of mental illness. Conversely, it predicted that individuals with higher premorbid health ratings, according to DSM-III-R, Axis V, would be diagnosed as having less severe forms of mental illness. Highly significant correlations were found between stress ratings and severity of disorder. Significant inverse relationships were also found between Axis V ratings and disorder severity. Additionally, several other demographic variables were significantly correlated with severity of disorder.

Comparative Models of the Impact of Social Support on Psychological Distress in Cancer Patients

Description: This study tested the relationship between Social Support, Psychological Distress, and Illness Stress in individuals who report cancer as a health condition. This study was based on archival data obtained from the Wave 1 of the Health and Retirement Study (HRS). The HRS provides a nationally representative sample of individuals aged 51 to 61 in 1992 and their spouses. The study sample was limited to cancer patients with a spouse or partner (n = 503). A structural equation modeling analysis procedure was used to test the theoretical models. Measures of social support were limited to variables assessing the participant's satisfaction with social support. Evidence was found for the Stress Prevention and the Support Deterioration models. This is congruent with previous research using measures of social support perception. Both the Stress Prevention and the Support Deterioration models predict a negative relationship between Illness Stress and Social Support. In addition, a univariate analysis of variance was used to test the stress buffering model. Similarly to other studies measuring the individual's degree of integration, or its perception, in the social network, the present research supported the only the Main Effect model and not the Stress Buffering model.

Psychological Stress: Effect on Humoral Immune Functioning as Measured by Immunoglobulin Levels

Description: The purpose of the present study was to determine if psychological stress, defined as academic examination stress, would systematically produce changes in immune parameters (immunoglobulin concentration) and psychological functioning. It was hypothesized that as examination stress occurred there would be an effect on immunological function consistent with heightened psychological activity/stress. Subjects were 23 master's and doctoral students in psychology who volunteered for the research project. All subjects were administered a series of psychological tests to measure stress, personality factors, emotional states, and anxiety levels. All tests were administered and.blood samples drawn over a period of 15 months across two lowstress and two high-stress periods. Immunological tests included white blood cell (WBC) differential count and radial immunodiffusion (RID) for the determination of concentration of different immunoglobulin classes (IgA, IgG, IgM) in serum. Data were treated to a one-way analysis of variance (ANOVA) with repeated measures, t /test for correlated samples correlational matrix between variables across assessments and discriminant function analysis. Results showed (1) increased immunoglobulin levels during periods of stress; (2) immunoglobulin G most consistently related to stress and probably most indicative of the stressed condition and biological resistance to stress; (3) anxiety related to external events; (4) increase in anxiety under stress; and (5) anxiety inversely correlated with emotional stability and coping skills while positively related to tension, increased number of somatic complaints, and obsessive-compulsive trends. Firm support was provided for the hypothesis that as stress occurred, there would be consistent changes in immunological functioning associated with heightened psychological activity/stress. It was concluded that a response pattern to stress was adaptive along both psychological- and immunological dimensions and that the concept of bodymind interaction was the most realistic approach to understanding the total response patterns.

Relaxation Training in Anxiety and Stress Management Differential Effects of an Audible vs. Imaginal Meditational Focus

Description: The hypothesis was tested that meditation using an audible word-sound would be superior to silent repetition of the same word in producing decrements in autonomic arousal and improvements in anxiety, mood, and the ability to cope with stress. The influence of hypnotic susceptibility upon improvement was also evaluated. Thirty subjects, assigned to one of three groups: audible meditation, silent meditation, and relaxation control, met one hour weekly for six weeks to practice their respective technique and discuss their progress. All subjects were evaluated using the Harvard Group Scale of Hypnotic Susceptibility, a medical symptom checklist, the Spielberger Trait Anxiety Scale, a self-rating of state anxiety, and factors C and Q4 of the 16PF. Finger temperature was taken as a measure of physiological arousal. Confidence ratings of the respective strategies were taken pre- and post-treatment.

Total Stress Load Inventory: A Validation Study

Description: The purpose of this study was to validate a stress inventory which would differentiate between a normative group and a patient population suffering from environmental illness. The hypotheses of this study were: (1) the Total Stress Load Inventory would be predictive in discriminating between clinical ecology patients and a normative group; (2) each section or subscale of the Total Stress Load Inventory would be predictive of psychological, cognitive, nutritional, and/or medical factors.

Family Stress Factors and Behavior Problems of Children

Description: This study examined the relationship among the factors of parental stress, marital adjustment, life event stress, and behavior problems of children and whether the sources and levels of parental stress, marital adjustment, and life event stress differed among families of children with . behavior problems and families whose children did not experience behavior problems. The subjects for this study were 60 mothers and their children from the North Texas metropolitan area chosen from two populations. Group I was composed of mothers of 30 children referred to a university related counseling center for behavior problems. Group II was composed of 30 mothers of children identified as not experiencing difficulty. Each mother completed the Parenting Stress Index (PSI), Short Marital Adjustment Test (SMAT), and Social Readjustment Rating Questionnaire (SRRQ). Hotellings T tests were used to determine whether the groups differed on sources and levels of parenting stress, marital adjustment, and life event stress. The groups differed significantly on the variables of sources and levels of parenting stress but not on marital adjustment or life event stress. The multiple regression technique was used to determine which variable or combination of variables would predict group membership. Parenting stress was found to be the best predictor of group membership. Based on this study, mothers who have a child with behavior problems do have an increased level of parenting stress. This increased level of stress is related to characteristics of their child and to their own personal characteristics. Those mothers who experience increased levels of parenting stress do not experience significantly less satisfaction in their marriages nor do their children experience more stressful life events than other children.

The Effects of Parenting Stress and Academic Self-Concept on Reading Ability in a Clinic Referral Sample

Description: This study investigated the relationships among the variables of parenting stress, academic self-concept, and reading ability. The purpose of this study was to determine whether parenting stress and academic self-concept contributed to the child's reading ability. Two hypotheses were investigated in an effort to accomplish this purpose. The subjects used in this study were forty-nine children and their primary caretakers referred to The Child and Family Resource Center, The University of North Texas, Denton, Texas, during the academic years of 1994 through 1999. Subjects ranged in age from seven to eighteen years of age. Academically, the subjects ranged from first graders through eleventh graders. All subjects lived in and attended schools in Denton County or neighboring counties. Parental employment ranged from unskilled laborers to medical doctors. The participating families included biological, step, adoptive, single, and divorced families. Abidin's Parenting Stress Index was used to measure parental stress experienced by the primary caretaker. The Intellectual and School Status cluster of the Piers-Harris Children's Self-Concept Scale was used to measure the child's academic self-concept and the Woodcock Reading Mastery Test-Revised provided a measure of the child's reading ability. Test scores were obtained following a review of The Child and Family Resource Center's documented files. Multiple regression statistics revealed no significant relationship between neither parenting stress and the child's reading ability nor the child's academic self-concept and reading ability. Standardized beta coefficients and bivariate correlation results indicated a relationship between academic self-concept and reading ability. Additional research is recommended for future research that encompasses a larger and more diverse sample.

The Influence of Psychological Stress and Personality upon Athletic Performance of Intercollegiate Tennis Players

Description: This investigation was designed to study coach and self-appraised groupings of intercollegiate tennis players who yield to stress and withstand stress and to determine if personality differences existed between groups. Subjects were 75 intercollegiate tennis players from Texas. A stress inventory and the Cattell Sixteen Personality Factor Questionnaire were instruments utilized in the study. Data were subjected to hierarchical profile-groupings, three-way analyses of variance, and a correlational analysis. Conclusions of the study were that intercollegiate tennis players and male and female players respond to stress differently; intercollegiate tennis players and male and female players who experience different levels of stress have different personalities; and players and coaches do not evaluate the ability to cope with stress similarly.

A Study of Stress Among Sixteen and Seventeen Year Old Adolescents

Description: To determine major areas of stress for adolescents, ninety-six sixteen and seventeen year olds were given a questionnaire which listed thirty-two situations which the subjects ranked in degrees of stress. The hypotheses examined the degree of family related and social related stress, the relationship of stress to age and sex, and the correlation between grade average and degree of stress. The first three hypotheses were tested by the t-test for mean differences. The fourth hypothesis used a Spearman rank order correlation coefficient. There was a difference in social stress and family stress, but no significant difference in stress of males and females or sixteen and seventeen year olds, and no significant correlation between grades and stress.

Police officers: Perception of self, occupational role, and occupational events.

Description: This study examined police officers' perceptions of self, occupational role and their relation to perceived stress and posttraumatic stress symptomology. Self-report measures for the study variables were completed by 101 police officers. Hypotheses predicted that perception of self and role would be associated with perception of stress and that perception of the stress would mediate PTSD symptomology. Neuroticism, job quality and general job satisfaction were the main predictors of stress. Stress levels mediated between 1) job quality and the symptoms of anxious arousal and impaired self-reference; 2) general job satisfaction and the symptoms of defensive avoidance and dissociation; and 3) neuroticism and the symptom of defensive avoidance. This implies that police officers' job quality, their feelings of general job satisfaction, and low levels of neuroticism are important in alleviating stress and subsequent psychological sequela.

Terrorism and strain: An exploratory analysis of the impact that individual strain and negative affect have on violent behavior among trained Turkish Hezbollah members.

Description: This study attempts to explore the strains that terror organization members experience prior to the training process in the organization. The primary goal of this research is to understand the relationship between the earlier experienced strains of terrorists and their violent behaviors. In the study a Turkish Hezbollah terror organization sample (N = 144) was utilized in the frame of Agnew's (1992) general strain theory. Initially, quantitative methods, such as bivariate analysis and multivariate analysis, were utilized to identify the cumulative effect of strains on the violent behaviors of terrorists. Later, by utilizing case studies with a qualitative approach the mediating effect of negative emotions (anger, frustration, depression and fear) were identified. This study found that among Turkish Hezbollah members, prior to joining the terrorist organization, individuals who experience higher levels of strain are more likely to perform violent acts when compared to individuals who experience lower levels of strain. This study affirmed earlier studies on strain-crime relationship. Moreover, utilized case studies support that negative emotions -specifically anger- mediate between strains and violent actions. In sum, this research retests and builds on Agnew's theory and argues that general strain theory can help terrorism studies to understand the sources of strains of terrorists and the effect of strains on their violent behavior.
