Abstract

This study contributes to the convergent and discriminant validity of the Psychiatric Diagnostic Screening Questionnaire (PDSQ) by investigating its correlations with the relevant clinical scales of the Personality Assessment Inventory (PAI) and life space variables, such as relationship status, education level, job loss, and history of suicide attempts. Bivariate correlations were calculated for a sample of 254 psychiatric outpatients. The results indicated that the PDSQ scales demonstrated good to excellent convergent and discriminant validity with target scales from the PAI. They were also found to be meaningfully associated with a variety of life space variables. For example, five of the subscales and the Total Score correlated positively with a recent job loss, and eight of the subscales were negatively associated with education and/or employment status. Some incongruence with hypothesized relationships was discovered for life correlates classified as markers of psychiatric severity. Overall, these findings add to the emerging body of evidence corroborating the convergent and discriminant validity of the PDSQ.
