The Problem Gambling Severity Index (PGSI) is considered a valid and reliable measure of problem gambling in the general population. This study compared the weighted scoring and binary scoring methods of the PGSI in identifying psychological factors that predict problem gambling. The researchers found that both scoring methods were valid and reliable. Both methods revealed four important predictors of problem gambling in people who do and do not bet on sports : (1) positive urgency; (2) amotivation; (3) luck/perseverance; and (4) gambling identity. The weighted scoring method also revealed two other predictors for people who bet on sports.
