Mode Effects in Self-Reported Mental Health Data

This article analyzes the impact of audio computer-assistedself-interviewing (ACASI) administration on the reporting ofmental health syndromes in a general population survey. Estimatesof four mental health syndromes (major depressive episode, generalizedanxiety disorder, panic attack, and agoraphobia) obtained froman interviewer-administered, paper-and-pencil (I-PAPI) mentalhealth module were compared with those obtained from an ACASIversion of the same module implemented in a separate field test.The mental health questions consisted of four scales from theWorld Health Organization's Composite International DiagnosticInterview Short-Form. Comparisons of ACASI and I-PAPI estimatesfor each mental health syndrome were made overall and withinage, race/ethnicity, gender, educational level, geographic region,and population density subgroups. To assess the likelihood ofreporting a mental health syndrome using ACASI versus I-PAPI,logistic regression models were utilized controlling for possibleconfounding and interaction variables. The results suggest thatadult respondents reported more mental health symptoms wheninterviewed with ACASI than when interviewed with I-PAPI, andthe results support the use of ACASI in general population surveysof mental health.
