A Self-Report Rating Scale to Screen for Psychiatric Disorders: Reliability and Validity Evidence Joyce Sprafkin, Ph.D., Kenneth D. Gadow, Ph.D., & Jayne Schneider, Ph.D., Department of Psychiatry, Stony Brook University, NY 11794-8790 Abstract Objective: There is a need for efficient rating scales to help psychiatrists screen for a wide range of DSM-IV disorders in adults. This study examines the reliability and validity of the Adult Self-Report Inventory-4 (ASRI-4)1. Method: A community sample of 450 males and 450 females between 18 and 75 years old (M=45.6) anonymously completed the ASRI-4. A subsample (N=219) completed the ASRI-4 a second time 2 weeks later. Other subsamples (N-114 to 276) completed the ASRI-4 and other validated measures that assess similar constructs as the ASRI-4 (PTSD Checklist2; Social Phobia Inventory3; Brief Symptom Inventory4; Mood Disorder Questionnaire5). A sample of 487 psychiatry outpatients also completed the ASRI-4. Results: Test-retest correlations (symptom severity scores) ranged between .61 and .94, and kappas (symptom count scores) were > .40 with few exceptions (Table 1). Correlations between ASRI-4 categories and the validity-evidence scales showed a fairly predictable pattern of convergence with scales containing similar symptoms and divergence with scales of dissimilar symptoms (Tables 2 & c). Clinic outpatients who received specific diagnoses scored significantly higher than those without such diagnoses on corresponding ASRI-4 categories (Figure 1). Conclusions: These preliminary findings provide evidence of the reliability and validity of the ASRI-4 as a measure to screen for many psychiatric disorders in adults.
