Primary Care Screening for Psychological Factors (open access)

Primary Care Screening for Psychological Factors

The Behavioral Medicine Questionnare (BMQ) is a 44- item instrument administered via a computer CRT display or pencil and paper. The BMQ was designed to help primary care physicians treating spinal disorders to screen for emotional factors which warrant further psychological evaluation. The test is composed of three scales: Anxiety, Depression, and Somatization. Concurrent validity for each scale was determined through comparisons with subject (n = 133) scores on clinician judgement ratings, pain drawings, and the MMPI. The psychometric properties of the test were supported through statistical analysis. Significant correlations were found between the BMQ, MMPI, and clinician ratings, with the latter showing relationships of lesser strength. The only significant correlation to subject generated pain drawings was to the BMQ depression scale. Analysis indicated the need for seperate norms for males and females. Further research is needed to facilitate measurement and interpretation of the BMQ.

Parkinsonian Personality: Psychometric Description of Intellectual-Motor Functioning (open access)

Parkinsonian Personality: Psychometric Description of Intellectual-Motor Functioning

In an attempt to determine the normative levels in health attribution and emotional, intellectual, and neuromuscular functioning in the parkinsonian population, 31 diagnosed parkinsonian volunteers recruited from exercise classes and/or organizations were tested. Health attribution was measured by the Health Attribution Test (HAT), personality factors by the Clinical Analysis Questionnaire (CAQ), general intellectual level by the Peabody Picture Vocabulary Test- Revised (PPVT-R) and the Intellectual Processes subscale of the Luria-Nebraska Neuropsychological Battery (Luria- Intelligence), and neuromuscular functioning by the McCarron Assessment of Neuromuscular Development (MAND) and Bender- Gestalt (BVMGT). Controls for comparisons were obtained from the clinical ecology population and normals for personality traits and the nonspecific neurologically impaired, healthy aging populations, and normals for intellectual and neuromuscular functionings. Chi-square and t-tests were computed on the data. Results indicated that the parkinsonians manifest less lower body strength (£ < .01), poorer balance with eyes closed (JD < .01), and slower fine motor speed (p < .05) than normals. The parkinsonians function significantly better in areas involving upper body coordination (p < .01, £ < .05) , slow-controlled movements (g.< .001), BVMGT (p < .05), and PPVT-R (p < .01) than the nonspecific neurologically impaired. On the Luria-Intelligence, 21 percent of …

Psychological Stress: Effect on Humoral Immune Functioning as Measured by Immunoglobulin Levels (open access)

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

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 …

Self-Directed Relaxation as a Treatment for Essential Hypertension (open access)

Self-Directed Relaxation as a Treatment for Essential Hypertension

Male (8) and female (22) Essential Hypertensives (130/85 mm Hg or above) were randomized into a nonspecific treatment or an experimental treatment utilizing eight relaxation strategies. Both groups had eight training sessions which consisted of baseline blood pressures (BP), 15 minute relaxation tapes, and post-relaxation BP's. Subjects were instructed to use their tapes three times between sessions. Five BP readings were taken at the one and two month follow-ups. It was hypothesized that the experimentals would have greater within and across session decreases in BP, and that the differences would be maintained during a no treatment follow-up. Eleven experimentals and 8 controls were on medication. Mean medication compliance percentages were 99.9 and 99.6 while mean relaxation compliance percentages were 95.2 and 115.2 for experimentals and controls respectively. Efficacy was checked at each training session on a seven-point scale and group means were 6.5 and 5.4 for experimentals verses controls. Within session decreases in BP were compared with t tests and no significant differences (p < .05) were present for the eight training sessions with systolic (SBP) or diastolic (DBP). Across session changes were compared with ANCOVA and no significant differences (p < .05) were present for the eight training or …

Ethnicity and Cognitive Complexity of Chronic Pain Patients (open access)

Ethnicity and Cognitive Complexity of Chronic Pain Patients

Sixty subjects divided equally among Anglo-Americans, Black Americans, and Hispanic Americans participated in the study. They were classified as chronic pain patients by medical diagnosis and duration of pain. They were drawing Workers' Compensation and were all blue-collar workers from the Dallas-Fort Worth area. Cognitive complexity is a measure of individuals' ability to construe their feelings, events of their lives, and their world in a meaningful manner. Cognitive complexity appeared to differ among the cultural groups as indicated by significantly different functionally independent construct scores. Anglo-Americans appeared to have a greater internal complexity than did Black Americans and Hispanic Americans.

Symptom Based Classification of Environmentally Ill Patients: an Exploratory Study (open access)

Symptom Based Classification of Environmentally Ill Patients: an Exploratory Study

The purpose of the present study was to discern a symptom pattern for environmentally ill patients and provide evidence of the uniqueness of the resultant pattern to this population. Patients' environmental exposure was confirmed by the presence of toxins in the blood serum. All patients were administered psychological and physical symptom checklists, the Clinical Analysis Questionnaire, and a standardized intermediate neuropsychological examination. Results indicate a response pattern of symptoms including fatigue, low energy, weakness, poor concentration, poor memory, poor comprehension, headaches, aches and pains, clumsiness, sinus discomfort, mucus, eye problems, restlessness, and present performance inferior to prior level of functioning. Presence of these symptoms, as well as the uniqueness of this symptom pattern was supported by comparisons of the patient and standardization groups on the two standardized tests.

The Psychophysiological Effects of a Running Program on Depression, Self-Esteem and Anxiety (open access)

The Psychophysiological Effects of a Running Program on Depression, Self-Esteem and Anxiety

The purpose of the present study was to investigate the psychophysiological effects of exercise on measures of cardiovascular fitness, depression, self-esteem, and anxiety. The 1.5 mile run (Cooper, 1972) was used to determine changes in cardiovascular fitness. The Zung Self-Rating Depression Scale was used to measure varying levels of depression. The Rosenberg Self-Esteem Scale was used to measure self-esteem. The Spielberger State-Trait Anxiety Inventory was used to measure state anxiety. An Electromyographic Assay and Digital Skin Temperature were performed on the Experimental and Corrective Therapy Groups in order to measure physiological concomitants of anxiety. A Body Composition Assay was performed in order to measure changes in body composition.

Factors of the Geriatric Depression Scale that may Distinguish between Four Cognitive Diagnostic Groups: Normal, Mild Cognitive Impairment, Dementia of the Alzheimer's Type, and Vascular Dementia

The purpose of the current study was to explore the relationship between cognitive status and depression in a sample of geriatric patients. Participants included 282 geriatric patients ranging in age from 65 to 96 years who were classified according to diagnosis as: DAT, VaD, MCI, and Norm. All were referred for neurocognitive testing from the Geriatric Assessment Program (GAP) at the University of North Texas Health Science Center (UNTHSC) in Fort Worth, Texas. This study sought to identify factor structures for two versions of the GDS using a geriatric sample of cognitively impaired and intact patients. It then compared these factors to each other to determine whether the GDS-15 is truly a shorter version of the GDS-30. These were then compared to a previously determined factor structure. This study explored whether the four-factors of the GDS-30 are able to differentiate cognitive diagnostic groups. Further, this study sought to identify whether the severity of cognitive decline impacted GDS factor score for each of the cognitively impaired groups. Results revealed a two-factor model of the GDS - 15 and a four-factor model with the GDS - 30. The GDS-15 factors did not differ from the first two factors of the GDS-30. Comparison …

Frontal Lobe Functions in Attention Deficit Hyperactivity Disorder from Children to Young Adults (open access)

Frontal Lobe Functions in Attention Deficit Hyperactivity Disorder from Children to Young Adults

Individuals with attention deficit hyperactivity disorder (ADHD) with and without a learning disorder (LD) and a control group of clinically referred individuals with behavioral problems were compared on four neuropsychological tests of frontal lobe functioning. Test results were collected to examine if ADHD individuals with and without LD have deficits in frontal lobe functioning. Two age groups were used to examine developmental differences. In the six to ten age group there were 27 ADHD, 17 ADHD/LD and seven other clinically referred individuals. In the 11 -20 age group there were 12 ADHD, 23 ADHD/LD and 24 other clinically referred individuals. The ADHD and ADHD/LD groups performed at a lower level than the other diagnostic group on the freedom from distractibility factor of the WISC-R and the omission and commission errors of the Gordon Diagnostic system. Differences for the ADHD and ADHD/LD groups were also found on the number of correct responses for the Gordon Diagnostic system, the Speech Sounds test and the Seashore Rhythm test. The developmental differences that were found were not influenced by diagnosis. The deficits that the ADHD individuals with and without LD demonstrated were not affected by age.
