IQ as a prognostic indicator in adult psychiatric first-admissions.
This study used IQ, along with measures of premorbid adjustment, health-sickness, symptom level, diagnostic severity and demographic data, to predict to 2-year outcome measures of level of functioning, health-sickness, and symptoms for a sample of 145 adult psychiatric first-admissions. It was hypothesized that IQ as an indicator of cognitive ability, or of general ability to adapt, would predict positively to improvement over the 2-year period. Data analysis was conducted with bivariate correlations and multiple regressions, using both absolute-level and residualized outcome variables. IQ showed modest, significant relationships with all absolute outcome indices and six of seven residualized measures, especially for a subsample of those with non-average IQ scores. Regressions showed that IQ provided independent prediction of symptom outcomes.
