Heart rhythm variability in persons with chronic pain.

Heart rhythm variability in persons with chronic pain.

Date: August 2008
Creator: Saxon, LaDonna Christine
Description: The present study evaluated the utility of heart rhythm coherence (HRC) feedback to reduce the reported pain intensity of patients enrolled in a multimodal pain management program. Participants were recruited and assigned to a usual treatment group (UT) or a heart rhythm coherence feedback group (UT+HRC). It was hypothesized that UT+HRC participants who achieved heart rhythm coherence would report a reduction of pain intensity, as measured by the McGill Pain Inventory. For those whose pain intensity decreased, it was also expected that their self reported levels of depression as measured by the Beck Depression Inventory-Second Edition and state anger as measured by the State Trait Anger Inventory would decrease. It is also hypothesized that with a reduction in pain levels, anger, and depression, blood pressure would also decrease among those who had high blood pressure prior to the intervention. Multivariate analyses of variance (MANOVA) were used to investigate the relationship between treatment condition, coherence status and pain levels. A series of independent t-tests were utilized to investigate the change in pain, depression, and state anger from baseline to posttest, followed by Pearson product moment correlation coefficients on difference scores to understand the relationship between the outcome variables for Hypothesis 2. ...

Hierarchical neuropsychological functioning in pediatric survivors of acute lymphoblastic leukemia.

Hierarchical neuropsychological functioning in pediatric survivors of acute lymphoblastic leukemia.

Date: August 2007
Creator: Larery, Angela R. D.
Description: Acute lymphocytic leukemia (ALL) is one of the most common types of pediatric cancers. Improvements in treatment within the last 20 years have resulted in reduced mortality and a greater focus upon quality of life. Several researchers have documented neuropsychological impairments in children following treatment for ALL; however, there have not been any comparative studies documenting differences in neuropsychological functioning based upon treatment modality despite the documented effects of radiation therapy and combined radiation/chemotherapy upon the developing brain. In addition, past studies have focused on unitary measures, ignoring the hierarchical relationship between basic cognitive functions and more abstract skills. This study examined the neuropsychological functioning of 81 children who were treated for ALL at a metropolitan children's hospital. All children were tested a minimum of two years after the final treatment session and were administered the NEPSY. Results do not support any interactions or main effects with the exception of the age of the child at diagnosis. Children diagnosed prior to the age of 5 showed greater impairments on tasks measuring attention, memory, and visuospatial reasoning in comparison to peers diagnosed after age 6.

Identifying AD/HD subtypes using the cognitive assessment system and the NEPSY

Identifying AD/HD subtypes using the cognitive assessment system and the NEPSY

Date: August 2001
Creator: Pottinger, Lindy Sylvan
Description: The purpose of this study was to examine the ability of the Cognitive Assessment System (CAS) and the NEPSY, A Developmental Neuropsychological Assessment, to differentiate between the subtypes of Attention Deficit/ Hyperactivity Disorder (AD/HD). The CAS and NEPSY are neuropsychological instruments which provide norms for AD/HD children in general. This study examined the performance of the two subtypes of AD/HD on the CAS and NEPSY. In addition, this study examined the performance of the two AD/HD groups on the Screening Test for Auditory Processing Disorders (SCAN). Since AD/HD children tend to have difficulty with language, the SCAN was used to determine if any of the AD/HD subjects had auditory processing difficulties that might impact their performance on the CAS and/or NEPSY subtests. The sample consisted of 118 children between the ages of 8 and 12 years of age. Using the DSM-IV criteria, the children were diagnosed as having three types of AD/HD: A Predominantly Hyperactive-Impulsive Type (AD/HD-HI), a Predominantly Inattentive Type (AD/HD-I) and a Combined Type The subtypes were also identified by the Attention Deficit Disorders Evaluation Scale-Home Version (ADDES-H). Only two subtypes, AD/HD-I and AD/HD-C, were identified by the ADDES-H. There were not enough AD/HD-HI subjects to include in ...

Improving the Definition of Exercise Maintenance: Evaluation of Concepts Related to Adherence

Improving the Definition of Exercise Maintenance: Evaluation of Concepts Related to Adherence

Date: August 2002
Creator: Wilcox, Susan E.
Description: Physical activity has been demonstrated in the literature as an effective way to reduce the risk for development of chronic disease. The Transtheoretical Model (TTM) of behavior change has been developed as a means to predict and facilitate movement into healthier lifestyle behaviors. The model is centered on "stages of change", which describe a continuum of readiness to engage in a health behavior change. Stages contain temporal, qualitative, and quantitative characteristics. This was a six-month study that evaluated the effectiveness of stage-matched (theorized to be pertaining only to the maintenance stage of change) vs. generic (theorized to be pertaining to anyone, regardless of stage) newsletters in assisting subjects to attain the Maintenance stage of change. It also sought to identify further qualitative characteristics that can differentiate between the Action and Maintenance stages of change. Results indicated that monthly stage-matched newsletters were no more effective in helping subjects reaching Maintenance than were the generic newsletters. Exerciser self-schema was related to stages of change, but those relationships differed from baseline to six-month follow-up, indicating development of exerciser self-schema during the study period. Implications of this are discussed. Other concepts discussed included "structure" of change process, in that three new scores were developed ...

Individual attachment styles and the correspondence/compensation hypotheses in relation to depression and depressive experiences.

Individual attachment styles and the correspondence/compensation hypotheses in relation to depression and depressive experiences.

Date: August 2008
Creator: Hill, Mary Kathleen
Description: Two hundred twenty individuals participated in the present study from a university population. The study examined the relationship among attachment styles to caregivers, relationship with God, depressive symptomology, and depressive experiences. Attachment theorists have suggested a connection between childhood attachment to caregivers and current attachment to God through the idea that individuals have "working models" that form how they interpret present relationships. For the most part, the results of the current study supported the idea of correspondence between attachment to caregiver and attachment to God. Individual attachment styles to caregivers matched their attachment style to God. However, when caregiver religiousness was included as a moderating variable, results supported the theory of combined compensation-correspondence for those with insecure attachments to caregivers. Individuals with insecure attachment to caregivers were more likely to compensate for their insecure attachment bonds through participation in religious activity, whereas their internal, private relationship with God corresponded with their previous insecure attachment bonds. Individuals with insecure attachment to caregivers were more likely to endorse symptoms of depression and report introjective, but not anaclitic, depressive experiences. With respect to attachment to God, introjective depressive experiences were positively related to both anxious and avoidant attachments, whereas, anaclitic depressive experiences were ...

Influence of executive function on medication adherence in neurologically impaired and non-impaired elderly.

Influence of executive function on medication adherence in neurologically impaired and non-impaired elderly.

Access: Use of this item is restricted to the UNT Community.
Date: August 2006
Creator: Zartman, Andrea Leigh
Description: Medication non-compliance has become one of the most prevalent reasons for hospitalization and doctor's visits by the elderly. As the elderly population is more likely to have decreased cognitive abilities, it is suggested that neuropsychological factors, especially executive function, are more influential in medication non-compliance than once thought. This study looked at executive function performance on a traditional battery of neuropsychological tests, self-report of perceived ability to perform executive function tasks, and the newly developed Pillbox Test, a performance based IADL measure. The Pillbox Test is designed to replicate a type of medication-management specific IADL as a means to asses executive function. Standard executive function measures only tap a portion of executive function, but it is believed that the Pillbox Test incorporates all four theoretical domains of executive function. The multiple measures of executive function performance were compared in three prevalent subgroups of the elderly population (mixed neurological group, cardiac medical-control group, and healthy community-control group). Results found significant differences, where the community-control and cardiac groups outperformed the mixed neurological group on the large majority of executive function tasks. Smaller differences were also noted between the community-control and cardiac groups and between the cardiac and mixed neurological groups. Together, these ...

An item response theory analysis of the Rey Osterrieth Complex Figure Task.

An item response theory analysis of the Rey Osterrieth Complex Figure Task.

Date: December 2008
Creator: Everitt, Alaina
Description: The Rey-Osterrieth Complex Figure Task (ROCFT) has been a standard in neuropsychological assessment for six decades. Many researchers have contributed administration procedures, additional scoring systems and normative data to improve its utility. Despite the abundance of research, the original 36-point scoring system still reigns among clinicians despite documented problems with ceiling and floor effects and poor discrimination between levels of impairment. This study is an attempt to provide a new method based upon item response theory that will allow clinicians to better describe the impairment levels of their patients. Through estimation of item characteristic curves, underlying traits can be estimated while taking into account varying levels of difficulty and discrimination within the set of individual items. The ultimate goal of the current research is identification of a subset of ROCFT items that can be examined in addition to total scores to provide an extra level of information for clinicians, particularly when they are faced with a need to discriminate severely and mildly impaired patients.

Natural Course of Adolescent Insomnia: Patterns and Consequences

Natural Course of Adolescent Insomnia: Patterns and Consequences

Date: August 2010
Creator: Roane, Brandy Michelle
Description: Approximately 2-11% of adolescents report chronic insomnia. The study used an archival data set from ADDHealth that assessed adolescent health and health-related behaviors. Adolescents (N = 4102) provided data at baseline (Time 1) and at 1-year follow-up (Time 2). Participants were excluded if no ethnicity, gender, or insomnia data were given at Time 1 or 2. Females were more likely to report insomnia than males at Times 1 and 2. In addition, adolescents with remitted insomnia were significantly younger than adolescents without insomnia at Times 1 and 2. Analyses found a prevalence of 9.6%, a remittance of 6.2%, an incidence of 4.4%, and a chronicity of 2.9%. At Time 1 and 2, AWI were significantly more likely to have depression, suicidal behaviors, and behavioral problems in school than AWOI. At Time 2, incidence and chronic insomnia increased the risk of depression, suicidal behaviors and behavioral problems in school. Risk and protective factors analyses indicated psychological counseling was associated with both remitted and chronic insomnia and depression was associated with incidence insomnia.

NEPSY profiles in children diagnosed with different ADHD subtypes.

NEPSY profiles in children diagnosed with different ADHD subtypes.

Access: Use of this item is restricted to the UNT Community.
Date: December 2006
Creator: Couvadelli, Barbara
Description: The purpose of this study was to determine if attention-deficit/hyperactivity disorder (ADHD) subtypes (predominantly hyperactive/impulsive, ADHD-HI; predominantly inattentive, ADHD-IA; combined, ADHD-C) exhibit distinct neuropsychological profiles, using the Attention and Executive Function subtests of the Developmental Neuropsychological Assessment, (NEPSY) and the omission and commission scores obtained on the Conners' Continuous Performance Test-II (CPT-II), a test that assesses attention processes. The sample was selected using archival data collected in a neurodevelopmental clinic over the past decade and consisted of 138 children between the ages of 6 and 12 years old. Using the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) (DSM-IV) criteria, the children were placed in either the ADHD-HI (n = 40), ADHD-IA (n = 35), or ADHD-C (n = 36) group, or a symptom free comparison group (n = 27). It was hypothesized that children with elevations on the impulsivity/ hyperactivity (ADHD-HI and ADHD-C) scale would be impaired on measures of inhibition and those with elevations on the inattention scale (ADHD-IA and ADHD-C) would be impaired on tests of attention, vigilance, and other executive functions. A one-way multivariate analyses of variance (MANOVA) was conducted (Group X Task), with significant results for overall main effect for group on the 7 ...

Neurocognitive implications of diabetes on dementia as measured by an extensive neuropsychological battery.

Neurocognitive implications of diabetes on dementia as measured by an extensive neuropsychological battery.

Date: December 2008
Creator: Harris, Rebekah Lynn
Description: Diabetes is a disease with a deleterious pathology that currently impacts 4.5 million individuals within the United States. This study examined the ability of a specific neuropsychological battery to identify and classify dementia type, investigated the impact of diabetes on cognition and analyzed the ability of the memory measures of the 7 Minute Screen (7MS) and the Rey-Osterrieth Recall to correctly categorize dementia type when not used in combination with a full battery. The battery in addition to exhaustive patient history, medical chart review and pertinent tests were used in initial diagnosis. Results indicated the battery was sufficient in the identification and classification of dementia type. Within the sample, diabetes did not appear to significantly impact overall battery results whereby only two measures were minimally affected by diabetes. Finally, the memory measures of the 7MS and the Rey-Osterrieth Recall were sufficient to predict membership into the Alzheimer's (AD) and vascular dementia (VD) groups with 86.4% accuracy. The classification percentage dropped to 68.3% with addition of the mild cognitive impairment category. The full battery correctly classified AD and VD dementia 87.5% and appeared to be the most robust.
