The Gambling Disorder Identification Test (GDIT) is a novel DSM-5 based gambling measure, developed analogously to the Alcohol Use Disorders Identification Test (AUDIT; Saunders et al., 1993), and the Drug Use Disorders Identification Test (DUDIT; Berman et al., 2005).

The GDIT has been developed in several interdependent steps, using a previous consensus-based framework for features of gambling measures known as the Banff Consensus Agreement (Walker et al., 2006), as an overall benchmark.

  • In the first step (Molander et al., 2019) four gambling researchers selected 30 items for proposed inclusion in GDIT, based on content analysis and categorization of a pool of 583 unique items from 47 existing gambling measures.
  • In the second step (Molander et al., 2021), preliminary construct and face validity were established. Sixty-one gambling experts from ten countries rated the 30 items proposed for inclusion in the GDIT, in an online Delphi process. Gambling researchers and clinicians participated in subsequent consensus meetings, yielding a 14-item draft version of GDIT. Face validity and item readability of the GDIT draft version were evaluated by obtaining user feedback from eight individuals with experience of problem gambling, as well as eight treatment-seeking participants fulfilling the criteria of GD.
  • In the final step (Molander et al., 2021), evaluation of the GDIT regarding psychometric properties was conducted among 603 gamblers from treatment- and support-seeking contexts, self-help groups, and population samples, in relation to diagnostic interviews assessing the DSM-5 criteria of Gambling Disorder, and other gambling measures.
