Background and Aims
DSM-5 provides nine diagnostic criteria for gambling disorder. All criteria have a pre-assumed equal diagnostic impact and are applied to all individuals and groups in an equal manner. The aims of the study are to analyse the structure underlying the diagnosis and to assess whether DSM-5 is equally applicable to different groups of gamblers.
Data from the 2009 German Epidemiological Survey of Substance Abuse and from a study on slot machine gamblers were used. Item Response Theory analysis was applied to estimate discrimination and severity parameters of the criteria. With the use of Differential Item Functioning analysis, potential criterion biases were analysed. We analysed data from 107 participants from the general population sample and 376 participants from the slot machine gamblers’ sample who answered a 19-item diagnostic questionnaire based on the DSM criteria for gambling disorder.
