Assessing gambling disorder using frequency- and time-based response options: A Rasch analysis of the gambling disorder identification test.

The frequency- and time-based item response options of the GDIT offer excellent measurement, allowing for elaborate assessment across both lower and higher gambling severity.

Notably, the 3-item GDIT Gambling Behavior subscale also shows potential as a brief screening tool for identifying at-risk gambling behavior.
