Study Overview
Brief Summary
The study examines the effectiveness of a computer-based self-help-program for individuals with problematic or 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 (primary outcome), depression and gambling-specific dysfunctional thoughts. The program is expected to lead to a significant reduction regarding all measures when compared to a control group. The study is conducted as a randomized-controlled trial with one intervention group and one wait-list control group.
Detailed Description
The study examines the effectiveness of a computer-based self-help-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 PG-Y-BOCS as a measure of the severity of pathological gambling symptoms. Secondary outcomes are rates of depression, measured with the PHQ-9 as well as gambling-specific cognitive biases, measured with the GABS. The program is expected to lead to a significant reduction in problematic/pathological gambling behavior (PG-Y-BOCS) and also to declines in both depressive symptoms (PHQ-9) and gambling-specific cognitive biases (GABS). The study is conducted as a randomized-controlled trial with one intervention group and one wait-list control group. The intervention group receives the login data directly following the baseline survey and can use the program over a period of 8 weeks, whereas the wait-list control group receives access to the program after completion of the post-survey.

Arms & Interventions
Online self-help program
The intervention group receives the login data for the online program directly following the baseline assessment. The program consists of 10 modules with many interactional exercises and homework-sheets.
Themes that are addressed in the online-program are for example self-esteem, sleep hygiene, problem solving strategies, mindfulness-based relaxation and attention exercises as well as gambling-specific topics such as money/debt management and impulse control. In addition, the user learns to modify negative and gambling-specific thought distortions, to integrate positive activities into his/her daily routine, strategies to deal with the urge to play as well as ways to regulate debts and to prevent relapse.
Intervention: Online self-help program (Behavioral)
Wait-list control group
The participants of the wait-list control condition do not receive any new intervention during the intervention period of 8 weeks, but may continue any treatment that has already been started before, including medication. Participants in the wait-list control condition receive full access to the program after completion of the post-assessment.
Outcomes
Primary Outcomes
Pathological Gambling Adaptation of Yale-Brown Obsessive Compulsive Scale (PG-Y-BOCS)
Time Frame: 1 week
The total score consists of ten items that measure the severity of gambling symptoms within the past week. The first five questions assess urges and thoughts associated with gambling, whereas the last five questions assess the behavioral component of the disorder. The sum score of each subscale ranges from 0-20. Each subscale can be analyzed separately as well as together as a total score (primary outcome). The total score can be interpreted as follows: 0-7 sub-clinical, 8-15 mild, 16-23 moderate, 24-31 severe and 32-40 extreme gambling symptoms.
Secondary Outcomes
- Patient Health Questionnaire - 9 depression module (PHQ-9)(1 week)
- Gambling Attitudes and Beliefs Survey (GABS)(time of assessment)
- South Oaks Gambling Screen (SOGS)(6 months)
