| Abstract: | A large, integrated survey data set provided by the Ontario Problem Gambling Centre was used to investigate psychometric properties
of the Problem Gambling Severity Index (PGSI). This nine-item self-report instrument was designed to measure a single, problem
gambling construct. Unlike its nearest competitor—the South Oaks Gambling Screen (SOGS)—the PGSI was designed specifically
for use with a general population rather than in a clinical context. The present analyses demonstrated that the PGSI does
assess a single, underlying, factor, but that this is complicated by different, multiple factor structures for respondents
with differing levels of problem gambling severity. The PGSI also demonstrated small to moderate correlations with measures
of gambling frequency and faulty cognitions. Overall, the PGSI presents a viable alternative to the SOGS for assessing degrees
of problem gambling severity in a non-clinical context.
