A Modwied Scoring Algorithm for the PDQ-R: Psychiatric Symptomatology and Substance Use in Adolescents with Personality DisordersColumbia University and The New York State Psychiatric Institute
Gettysburg College
Loyola College of Maryland A study was conducted to investigate the extent to which adolescents diagnosed with one or more personality disorders on a self-report instrument are at an elevated risk for psychiatric symptomatology and psychoactive substance abuse. A modified version of the Personality Diagnostic Questionnaire-Revised (PDQ-R), the Revised Hopkins Symptom Checklist (SCL-90-R), and a standard retrospective substance use diary were administered to 441 undergraduate students, 181 and 166 of whom participated in 1- and 2-month follow-up sessions at which the SCL-90-R and the substance use diary were read ministered. Results were that (a) personality disorder prevalence estimates produced by the modified PDQ-R approximated those obtained by previous researchers who have administered structured clinical interviews to general community samples; and (b) individuals diagnosed with one or more personality disorders by the modified PDQ-R manifested higher levels of psychiatric symptomatology and substance use at both baseline and follow-up than did nondiagnosed subjects.
