Abstract

Objective: The aim of this study was to compare the prevalence of psychiatric diagnoses when the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA-II) interview was administered in person with the prevalence when the SSAGA-II was conducted by telephone. Method: As part of the Collaborative Studies on the Genetics of Alcoholism, SSAGAs were administered either by telephone (n = 1,294) or in person (n = 1,484) to adult relatives of probands (42.3% male). The two modes of interview were compared with respect to reported lifetime prevalence of (1) Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) alcohol dependence; (2) other DSM-IV substance-dependence diagnoses (nicotine, marijuana, cocaine, opioid, stimulant, sedative); and (3) DSM-IV nonsubstance diagnoses (i.e., antisocial personality disorder, major depressive disorder, mania, panic, social phobia, obsessive-compulsive disorder, and generalized anxiety disorder). These analyses took into account the potential confounds of gender, age, race, education, income, marital status, and potential within-family correlation. Results: Diagnostic prevalence rates for alcohol dependence and major depressive disorder were lower for telephone interviews than for in-person interviews (7% and 2%, respectively); there were no other significant differences. Conclusions: When circumstances dictate (e.g., subject out of area, subject preference), telephone administration of the SSAGA should be considered.
