New publication: Are general and activity-specific PGSI scores consistent?
Researchers at the Chair published a new article titled Are general and activity-specific PGSI scores consistent? in the Journal of Gambling Issues.
Gambling research has highlighted substantial activity-specific differences in gambling behaviours, but measures of problem gambling remain non-specific. This paper aims to examine the consistency of general versus activity-specific Problem Gambling Severity Index (PGSI) scores among a sample of moderate-risk and problem gamblers in Québec, Canada. Correlations and t tests were conducted to examine associations and differences between general and activity-specific PGSI scores. Results were analyzed by number of activities reported and activity rank for lottery, video lottery terminals (VLTs), and slot machines and suggested that PGSI scores may not accurately reflect problem gambling severity for all specific activities. General and activity-specific PGSI scores were more highly correlated when lottery was the primary activity, whereas for VLTs, scores were highly correlated regardless of number or rank of activities. General PGSI scores were significantly higher than activity-specific scores for lottery, but general and activity-specific scores were not significantly different for VLTs, demonstrating that the PGSI is a better indicator of activity-specific scores for some forms of gambling over others. Researchers conducting population surveys should exercise caution in assigning general PGSI scores to specific activities.
