Summary

The study examines the efficacy and acceptance of a computer-based training program for individuals with problematic or pathological gambling behavior. The study intends to investigate the extent to which the computer-based training program leads to a significant reduction in pathological gambling (primary outcome) when compared to a control group. The study design is a randomized-controlled trial with one intervention group and one wait-list control group.

Detailed description

The study examines the efficacy of a computer-based training program for individuals with problematic and pathological gambling behavior. The main objective of the study is to investigate the extent to which the online program leads to a significant reduction in pathological gambling. The primary outcome is the Pathological Gambling Adaptation of the Yale-Brown Obsessive Compulsory Scale (PG-YBOCS total score) as a measure of the severity of pathological gambling symptoms. Secondary outcomes are further measures of gambling-related symptoms, such as the South Oaks Gambling Screen (SOGS), as well as rates of depression, measured with the Patient Health Questionnaire - 9 items depression module (PHQ-9), and rates of impulsivity, measured with the impulsivity subscale of the Eysenck's Impulsivity Inventory (I-7). The training is expected to lead to a significant reduction in problematic/pathological gambling behavior (PG-YBOCS) and all secondary outcomes when compared to a control group. The study design is a randomized-controlled trial with one intervention group and one wait-list control group and two assessment times (pre and post). The intervention group receives the download link for the training program directly following the baseline survey and can use the training over a period of 8 weeks, whereas the wait-list control group receives access to the training after completion of the post-survey.

Conditions

• Gambling, Pathological

Interventions

Type	Name	Description
BEHAVIORAL	Retraining (AAT)	The training program is based upon the approach-avoidance task (AAT) and can be easily performed on a computer, laptop or tablet. There is a total of 20 pictures, 10 slot-machine gambling related pictures and 10 neutral pictures that were already used in a prior study (Wittekind et al., submitted). The pictures appear on the computer screen and have to be either pushed or pulled. Pushing and pulling depends on a masked instruction (not related to the content of the pictures, but to the color of the frame). All gambling-related pictures are framed with the color that is instructed to be pushed, all neutral pictures are framed with the color that is instructed to be pulled.
