The aim othis 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.
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.
When circumstances dictate (e.g., subject out of area, subject preference), telephone administration of the SSAGA should be considered.
