The use of the Minnesota Multiphasic Personality Inventory (MMPI) and the Health Attribution Test (HAT) for predicting referral compliance to a state vocational rehabilitation program was evaluated. Subjects included 53 patients (26 males, 27 females) who were chosen at random three to 18 months following discharge from an inpatient chronic and spinal pain center. Subjects were administered the MMPI and HAT upon hospital admission and seven outcome measures of referral compliance were obtained. A discriminant analysis was performed to test the hypothesis that certain items would best discriminate compliance. Most discriminative of compliance was the MMPI validity scale K (Wilks Lambda = .751, p ≤ .033). A regrouping of data into two groups, active and inactive, yielded ego strength (MMPI, ES) and ability to trust others (PA) as significant differentiating variables.

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 the parkinsonians compared to eight percent of the healthy aging were within the limits for brain damage (JD < .01) . Although the parkinsonians are internals for health attribution, their internal orientation is lower and external locus of control higher than the clinical ecology population (j> < .01). The parkinsonians' CAQ profile was significantly different in comparison to the clinical ecology patients on the following CAQ factors: F (impulsivity), H (boldness), N (shrewdness), 0 (insecurity), Q2 (self-sufficiency), D4 (anxious depression), Pp (psychotic deviation), As (psychasthenia), IN (independence), and So (socialization). The parkinsonians' CAQ profile was negative for depression. Their CAQ profile can be interpreted as being associated with positive adjustment. The results were interpreted as applying to health care provision for the chronically ill.

The relationship between health attribution belief systems and compliance in an ecological treatment regimen was examined in 40 patients with environmental illness. Internal and chance scales on the Health Attribution Test (HAT) were found to be related to reported level of compliance for each subject. Data were subjected to Chi square analysis with highly significant results obtained. Ecology patients appear to take responsibility for their own health and treatment and, although they feel themselves to be victims of fate, they comply with treatment on a high level.

One hundred persons applying for services with the Texas Rehabilitation Commission with reported disabilities of alcohol/substance abuse or back injury/pain were selected for study. Subjects were assigned to two groups (alcohol or back) according to their reported disability. They were tested within one week of application and after 60 days were checked to see what rehabilitation status they were in to determine success or failure. Alcohol clients were administered the Health Attribution Test (HAT), 16PF, and an Alcohol Imagery questionnaire developed for this study. Back clients were administered the HAT, 16PF, and Pain Drawings. Statistical procedures including Pearson correlation, stepwise discriminant analysis, and discriminant analysis were performed. The HAT Internal Factor showed a significant relationship to rehabilitation success or failure and the 16PF motivation indices approached significance. The discriminant analysis demonstrated that success or failure could be predicted at a significant level using these measures. Issues of practicality in using these instruments (particularly imagery measures) in a rehabilitation counseling practice were noted.
