Objective: This study investigated beliefs about help seeking, treatment options, and expected outcomes for alcohol abuse, dementia, depression, obsessive-compulsive disorder (OCD), and schizophrenia, by using a vignette-based approach.Methods: The Mind Matters study was a comprehensive, population-based, cross-sectional survey conducted among Singapore residents (N=3,006) ages 18 to 65 to establish the level of mental health literacy. Questions were asked about whom the person in the vignette should seek help from, the likely helpfulness of a broad range of interventions, and the likely outcome for the person in the vignette with and without appropriate help.
