The Psychological Screening Inventory as a predictor of predisposition to suicide among patients at the Oregon State Hospital.

Examined all closed patient files for the inclusion of scores from the Psychological Screening Inventory (PSI) at the Oregon State Hospital between 1977-1979. Subsequently, the patient files (N = 123) were assessed for suicidal inclination employing five categories, which ranged from "no suicidal ideation" to "serious attempt." t-tests were completed between Ss placed in category 1 (no suicidal ideation) and remaining categories. Results yielded a significant value for "discomfort," with lower discomfort scores related to higher suicide risks. Subsequent extreme group analysis yielded significant but opposite results for males and females, which suggests the importance of evaluating the results of the PSI separately for sex.
