Prevalence of Treated and Untreated DSM-III Schizophrenia Results of a Two-Stage Community Survey

By comparison with the PSE-ID system, we showed that the GHQ-60 could be used with good results as a screening instrument in the first of a two stage community survey. Unlike the sensitivity and negative predictive values, the specificity and positive predictive rates reach low figures in this study. The global efficiency and positive and negative predictive values of the test are significantly improved by raising its cut-off score, but at the expense of great reduction in sensitivity. The revised scoring system failed to provide better prediction of caseness' than conventional scoring. The GHQ does not distinguish fully between persons in the community afflicted by ‘transient states of distress' and those whose symptoms would classify them as cases' by the PSE.

Phenylene Sulfide

We are studying the crystallization and annealing behavior of high performance polymers, like poly(p-pheny1ene sulfide) PPS, and poly-(etheretherketone), PEEK. Our purpose is to determine whether PPS, which is similar in many ways to PEEK, undergoes reorganization during annealing. In an effort to address the issue of reorganization, we are studying solution grown single crystals of PPS as model materials.Observation of solution grown PPS crystals has been reported. Even from dilute solution, embrionic spherulites and aggregates were formed. We observe that these morphologies result when solutions containing uncrystallized polymer are cooled. To obtain samples of uniform single crystals, we have used two-stage self seeding and solution replacement techniques.
