The poor reliability of the DSM diagnostic system has been a major issue of concern for many researchers and clinicians. Standardized interview techniques and rating scales have been shown to be effective in increasing interrater reliability in diagnosis and classification. This study hypothesized that the utilization of the Psychological Rating Scale for Diagnostic Classification for assessing the problematic behaviors, symptoms, or other characteristics of an individual would increase interrater reliability, subsequently leading to higher diagnostic agreement between raters and with DSM-III classification. This hypothesis was strongly supported by high overall profile reliability and individual profile reliability. Therefore utilization of this rating scale would enhance the accuracy of diagnosis and add to the educational efforts of technical personnel and those professionals in related disciplines.

Two separate experiments were designed to measure urinary cyclic AMP and renal papillary cyclic AMP, respectively, Results suggest that urinary cyclic AMP excretion rate is unchanged and cannot be used as an index of tubular sensitivity to either vasopressin or fluoride. However, renal papillary tissue cyclic AMP increased significantly (p<0.05) at plasma fluoride concentrations which result in polyuric renal failure. Further, it appears that fluoride independently stimulates cyclic AMP in the papilla, demonstrated by the additive effect with vasopressin. It was postulated that the defect in water reabsorption induced by fluoride must be at a step subsequent to the generation of cyclic AMP, because one would expect to see an antidiuresis, not a diuresis with increased tissue cyclic AMP.

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.
