This study examined harms experienced by affected others (AOs) that were attributed to gambling. The quantitative phase used survey data from 197 AOs to identify the rates of harms across different domains. The qualitative phase used interview data of 20 AOs to explore their lived experience of these harms in depth. Data came from the Fourth Social and Economic Impact Study (SEIS) of Gambling in Tasmania, Australia. Overall, emotional or psychological harm was the most common domain of harm, reported by almost all AOs (90%). About 76% of AOs reported relationship harm. Other common domains of harm included financial harm, health harm, work or study harm, and other harm. Analysis of the interview data revealed interconnections between the different harm domains.
