Behavior Patterns among Children with a History of Metopic Synostosis (open access)

Behavior Patterns among Children with a History of Metopic Synostosis

Metopic synostosis is a condition in which the metopic suture of the human cranium fuses prematurely and may be related to poor behavioral inhibition leading to behaviors commonly associated with Attention-Deficit Hyperactivity Disorder (ADHD). The purpose of this project was to examine the behavior patterns among children with a history of metopic synostosis. It was hypothesized that children with a history of metopic synostosis would exhibit many of the same behavioral patterns associated with ADHD. It was also hypothesized that children with a history of simple synostosis not involving the metopic suture would not evidence this type of behavioral pattern. In order to test these hypotheses, the behavior of three groups of children was compared including (1) children who had a history of metopic synostosis (M= 7.63 years, SD = 1.92 years), (2) children who had a history of simple craniosynostosis not involving the metopic suture (M= 7.54 years, SD = 1.88 years), and (3) a group of children diagnosed with ADHD (M=7.78 year, SD = 1.87 years). It was found using the Home and School versions of the Attention Deficit Disorders Evaluation Scale (ADDES) that children with a history of metopic synostosis demonstrate significantly more behavioral disturbances than children …

Autonomic Balance and Control of Stress for Participants Identified as High or Low Hostile and as Having a Positive or No Family History of Cardiovascular Disease (open access)

Autonomic Balance and Control of Stress for Participants Identified as High or Low Hostile and as Having a Positive or No Family History of Cardiovascular Disease

The influence of autonomic activation in response to controllable versus noncontrollable stress, anger imagery induction, and relaxation imagery was studied among 80 participants between the ages of 18 and 34. Participants differed in level of trait hostility as assessed by the Irritability Subscale of The Buss-Durkee Hostility Inventory (Buss & Durkee,1957) and the Ho scale of the Cook-Medley Hostility Inventory (Cook & Medley, 1954). Groups were further subdivided with regards to either having a positive family history of cardiovascular disease or having no significant history. Results were obtained through analyses of electrocardiograph R-R intervals which produced an index of autonomic nervous system activation. Findings supported hypotheses involving the relations between autonomic balance and stress and hostility for the female and male populations. Among both populations, parasympathetic regulation was diminished during anger induction for individuals with high levels of trait hostility and having a family history of cardiovascular disease. Similar results were obtained for men during relaxation imagery induction.

Family Environment, Social Support, and Psychological Distress of Women Seeking BRCA1 and BRCA2 Genetic Mutation Testing (open access)

Family Environment, Social Support, and Psychological Distress of Women Seeking BRCA1 and BRCA2 Genetic Mutation Testing

Shared characteristics and predictors of psychological distress are beginning to be identified in research on women seeking genetic testing for BRCA1 and BRCA2 gene mutations. This study further explored patterns of psychological distress for 51 community women waiting to receive such genetic test results. There was no significant relationship between psychological distress and family cancer history, personal cancer history, social support networks, and family environment. Women in this sample tended to rely more on females and relatives for support than males and friends. Social support satisfaction was not related to gender or number of relatives providing support. Thirty-four of the 36 women classified on the family environment type were from Personal Growth-Oriented families. Comparisons with normal and distressed family means revealed increased cohesion and expressiveness with decreased conflict, indicative of supportive family environments. Limitations and implications are discussed.

Muscle Tension and Locus Of Pain in Subjects With and Without Chronic Backpain (open access)

Muscle Tension and Locus Of Pain in Subjects With and Without Chronic Backpain

The purpose of the study is to examine the relationship between the location of the initial onset of back pain as revealed by the subject's pain drawing and the site of maximum muscle tension at rest, while jaw-clenching and during a cold stressor, in men and women. Subjects were 30 males and 30 females divided into three groups of 10 males and 10 females each and designated according to back pain history as no back pain (NBP), upper back pain onset (UBP) and lower back pain onset (LBP). Six bipolar, bilateral electromyographic (EMG) recording sites were instrumented on each subject. EMG levels were recorded from the forehead, forearm, upper back, lower back, thighs and ankles under conditions of rest, jaw-clenching and a cold stressor. Seven hypotheses predicted that EMG levels would distinguish groups and gender of the subjects and that interactions would exist between site of pain onset and EMG elevations.

Women Receiving Genetic Counseling for Breast Cancer Risk: Cancer Worry, Psychological Distress, and Risk Recall Accuracy

Access: Use of this item is restricted to the UNT Community
This follows an earlier study of the same data set, which, through its findings, presented new questions that are investigated in this study. Both studies used a prospective controlled design, wherein women receiving genetic counseling for breast cancer risk were randomized into two groups. Subjects receiving an audiotaped recording of their genetic consultation (tape group) were compared to subjects who also had a genetic consultation but did not receive an audiotaped recording of it (no-tape group). Participants were drawn from attendees at the genetic clinics of two London hospitals and included 115 women with a family history of breast cancer. Cancer worry and psychological distress were assessed before genetic consultation (baseline), and at one- and six-month follow-ups by post. Objective risk was estimated by the geneticist during the consultation, and subjective risk was assessed at one month follow-up. The goals of the current study were to investigate relationships between cancer worry, psychological distress, and recall of genetic risk for breast cancer in a sample of women receiving genetic counseling for breast cancer risk, and to investigate the role sociodemographic variables on cancer worry, psychological distress, or risk recall for these women. Results for this sample of women with a family …

Organization of Narrative Discourse in Children and Adolescents with Acute Traumatic Brain Injury

Children with a recent history of TBI often demonstrate impaired memory, which can be affected by impaired attention, processing speed or impaired verbal information processing. The purpose of this study was to determine if qualitative differences exist among the narrative recall of TBI patients that is not adequately accounted for by standard scoring methods. Sixty-six TBI subjects ranging in age from 6 to 16 were given the Wide Range and Memory and Learning (WRAML) Story Memory subtest and selected subtests from the Wechsler Intelligence Scale for Children - Third Edition (WISC-III). Mean elapsed time since injury was 53 days. Recall of the story on the WRAML subtest was hand-recorded by the examiner. A supplemental scoring method accounted for differences in length, errors, and disorganization. Comparisons were made to a randomly selected control group consisting of 16 hospitalized subjects between 7 and 15 years with no history of head injury, neurological condition or event. Findings suggest the WRAML Story Memory subtest is relatively robust in providing information regarding the quality of recall, with the exception of not accounting for the addition of erroneous details. Subjects with both cortical and subcortical injuries were more likely to add superfluous details to their stories. …

Neurocognitive implications of diabetes on dementia as measured by an extensive neuropsychological battery. (open access)

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

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.

The Effects of Positive Emotion, Negative Emotion, Flourishing, and Languishing on Cardiovascular Risk (open access)

The Effects of Positive Emotion, Negative Emotion, Flourishing, and Languishing on Cardiovascular Risk

Positive psychology has led a movement that concentrates on positive characteristics. The current study examined the relationship between positive emotions, negative emotions, flourishing, languishing, and cardiovascular functioning. The study uses guided imagery to help participants recall a negative emotional event and positive emotional event in a counterbalanced order. The reverse order allowed us to examine the differential contributions of stress buffering versus facilitated recovery effects to higher levels of heart rate variability (HRV). The study also examined the relationship between mental health categories and known cardiovascular disease risk. Univariate analysis of variance revealed that positive emotions can serve as a stress buffer and dampen cardiovascular responses to a negative event. Also, analysis revealed a trend for the prediction that positive emotions can facilitate cardiovascular recovery following a negative event. Exploratory analysis did not reveal differences between a facilitated recovery group and a buffering group for cardiovascular measures. Future studies should include tighter control to help compare the differential influences of stress facilitation and stress buffering on cardiovascular functioning. The results from the study indicate that it is still too early to tell whether mental health buffers those individuals from developing CVD, and to answer whether languishing increases the risk of …

Association Between Folate, Vitamin B12 and Cognitive Performance in Demented Elderly. (open access)

Association Between Folate, Vitamin B12 and Cognitive Performance in Demented Elderly.

Dementia is prevalent among elderly people. As the world population ages, it is projected that the number of people affected by dementia may triple in the next 50 years. Over the last two decades, research has focused on identifying potentially modifiable risk factors in development and progression of dementia, such as vitamin B12 and folate. Results concerning the effects of low folate and vitamin B12 on cognitive performance are mixed. The main objective of the present study was to investigate the effects of vitamin deficiency on cognitive functioning in a clinical sample of elderly individuals with cognitive problems using a comprehensive neuropsychological assessment. A retrospective chart-review was performed on the 102 records of patients from the Geriatrics Clinic at the University of North Texas Health Science Center who presented with cognitive deficits. Charts were reviewed to obtain data on vitamin supplementation, vitamin status, history of chronic conditions and other biochemical data. The available database was used to obtain data on neuropsychological assessment. The study demonstrated mild association between vitamin B12 and folate status and cognitive deficits. There appeared to be a higher cut-off level that is above the traditionally used levels for vitamin B12 and folate deficiency concentrations at which …

Predictors of Hiv-related Neurocognitive Impairment in an Hiv/aids Population (open access)

Predictors of Hiv-related Neurocognitive Impairment in an Hiv/aids Population

Although, in the United States HIV infectivity has increased, survival rates have also improved due to highly active antiretroviral therapies (HAART). Adherence to HAART successfully prevents the progression of AIDS and AIDS-related morbidity for many living with HIV. Unfortunately, HAART’s permeability into the central nervous system (CNS) is limited; thus, the prevalence of HIV-associated neurocognitive disorders (HAND) still persists. The health belief model (HBM) is the theory often used to explain and predict behavior in relation to chronic illness. This model incorporates perceptions of susceptibility, vulnerability, and severity towards a particular illness, and beliefs regarding perceived efficacy and benefits of treatment. This study expands the existing model. Many who live with HIV have a long history of negative experiences, such as stigmatization, traumatic events, and discrimination. I examined supplementary psychosocial and physiological predictor variables, such as stigma, trauma, ethnicity, general medical conditions, HIV-opportunistic infections, and falls; all relevant to disease progression in HIV. Previous researchers found links between stigma and immune function, trauma and memory, ethnicity and neuropsychological impairment, and symptom load and CNS-related alterations. Therefore, this study examined how these different psychosocial predictor variables are associated with HIV-related neurocognitive impairment. My model explained 38.6% of the variance in the …

QEEG and MMPI-2 patterns of adults reporting childhood sexual abuse: Determining differences and predictor models. (open access)

QEEG and MMPI-2 patterns of adults reporting childhood sexual abuse: Determining differences and predictor models.

Childhood sexual abuse (CSA) has been linked to a number of adult psychological maladies. The MMPI-2 has shown specific patterns such as an inverted V in the validity scales, a floating profile, and a 4-5-6 configuration to be present more often in adults who have experienced childhood trauma. Both children and adults who have experienced trauma have shown a number of neurophysiological differences when compared to non-traumatized individuals. However, little research has looked at differences in quantitative electroencephalography (QEEG) patterns in these individuals. The purpose of this study is to determine differences seen in the MMPI-2 and the QEEG when comparing adults who report CSA to adults who deny any history of childhood abuse. Differences between the two groups in MMPI-2 basic scales and supplementary scales PK and PS were determined. This study also examined the ability to correctly classify individuals into the two groups using three patterns seen in the MMPI-2 basic scale profiles (inverted V, floating profile, and 4-5-6 configuration). In addition, this research included exploratory analyses to develop predictor models for CSA group membership. Predictors in the models were derived from MMPI-2 scales, alpha relative power at each of the 19 sites in the International 10/20 electrode …

Enkephalin Hydrolysing Activity in Alcoholism and Related Changes in Mood and Ability to Perform a Biofeedback/Relaxation Task

Evidence linking the development of chronic alcoholism with endogenous opioid peptides is reviewed. Particular emphasis is placed on enkephalin metabolism with respect to its involvement in the development of addiction and stress-related psychophysiological changes. The study was concerned with enkephalin hydrolysing activity (EHA) in chronic alcoholism as well as the mood changes that reportedly accompany alcoholism. Also of interest was the relationship of enkephalin degradation to voluntary relaxation.

Transportation trauma and psychological morbidity: Anxiety, depression, PTSD and perceived control in a hospitalized sample. (open access)

Transportation trauma and psychological morbidity: Anxiety, depression, PTSD and perceived control in a hospitalized sample.

Transportation-related collisions are ubiquitous and often traumatic. Identifying post-collision psychological distress and the characteristics of the collision survivor that lead to distress are vital to the development of early and appropriate interventions. The goals of this study were: 1) to use a questionnaire as opposed to a typical diagnostic interview, 2) to confirm that psychological distress is present in currently hospitalized transportation-related collision survivors, 3) to confirm that different types of distress co-occur, 4) to determine if distress is more likely to occur in those who have had prior distress, and 5) to explore the relationship between symptoms of distress and perception of control by self, others, and God/Higher Power of past, present, and future collision-related events. Subjects were 100 English speaking adult inpatients, 16 years and older, who were less than 3 weeks post-injury, and receiving some rehabilitation. Participants completed a questionnaire which included the Center for Epidemiologic Studies Depression Scale (CES-D), Beck Anxiety Inventory (BAI), and Davidson Trauma Scale (DTS) as well as questions regarding demographics, details of the collision/injury, alcohol/drug use, pain, past and present stressors, social support, and perceptions of life change. Information about head injury and collision-concurrent alcohol and/or drug use was collected from the …

Relaxation Imagery to Facilitate Endogenous Control of Lymphocytic Function in Humans

Whether an individual's state of mind can influence the body's immune system has been studied for several decades. Historical notions of a homeostatic, self-contained, and self-monitored system have been discarded. Studies have explored conditioning effects and cognitive behavioral methods to affect the immune response. This study is based on the assumption that relaxation imagery can be used as an endogenous means to produce specific physiological change in the immune function. Subjects were instructed to make a directional change in the absolute number of peripheral lymphocytes using relaxation imagery.

Health Disparities among Sexual Minorities: Trends of Health Care and Prevalence of Disease in LGB Individuals

The primary focus of the current study was to identify health disparities between sexual minority subgroups by examining differences of health indicators in lesbians, gay men, and bisexual individuals, and compare these to their heterosexual counterparts. Data was drawn from the National Health and Nutrition Examination Survey (NHANES), and variables examined in sexual minorities were related to health care access and utilization, risky health behaviors, and overall disease prevalence and outcomes. Findings suggest there are still some current health disparities in terms of insurance coverage, access to medical care, substance use, and prevalence of certain health conditions. However, a trend analysis conducted to examine three NHANES panels, suggests a mild improvement in some of these areas. Further findings, discussion, limitations of the study, current implications, and future directions are addressed.

Mental Status, Intellectual, and Mood States Associated with Environmental Illness Patients

The purpose of the present study was to begin development of a psychological profile for environmentally ill patients. Existing psychiatric labels are unable to encompass these patients. Test scores were drawn from a pool of 89 patients whose environmental exposures were verified by the presence of toxins in the blood serum. A Mental Status Exam, a Wechsler Adult Intelligence Scale-Revised screen, and the Profile of Mood States were administered. Results indicate a primary pattern which is significantly different from test norms consisting of fatigue, reduced mental functioning, and a lack of psychotic or personality disorder indicators. The reported symptoms of environmentally ill patients were objectively verified by current psychological test instruments. The need for a new diagnostic category for people who have been poisoned by environmental toxins is discussed.

Does Unemployment Become a Major Stressor in the Evolution of Chronic Pain?

Pain has been described as the most complex human experience and most frequent reason patients seek medical treatment. Few people fail to experience the pain associated with disease, injury, or medical/surgical procedures. However, the impact of unemployment that results from chronic pain suffering has not been widely researched. To present a comprehensive view of the effect unemployment has upon the chronic pain experience, this study focused upon stress philosophy, chronic pain, employment, and coping effectiveness. The Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and a Personal Data Questionnaire (PDQ) were administered to 96 persons (four groups of 24 subjects) representing either unemployed or employed and either chronic or non-chronic (acute) pain populations.
