Background and study aims
The DSM IV (American Psychiatric Association, 2000) defines pathological gambling as 'Persistent and recurrent maladaptive gambling behavior' with at least 5 out of 10 associated criteria required to be attained in order to merit the diagnosis. In the US, problem gambling is often considered to be a sub-clinical form of pathological gambling but in many other jurisdictions, the term 'problem gambling' (PG) is used to encompass all people with a significant gambling problem. Problem gambling often has important health and social consequences for those who have it. Divorce rates are high, family violence and relationship problems generally are more common. Bankruptcy rates and participation in criminal activity related to money are also higher amongst this group than in the general community. A recent Cochrane review of the problem gambling treatment literature has found that psychological treatments, such as cognitive behaviour therapy and motivational interviewing, could be helpful in reducing problem gambling. These reviews also identified the current gaps in knowledge about effective treatments for problem gambling and have shown that more research is required to determine which treatment is most effective, and which one works best for whom. The purpose of this study is to investigate the effectiveness of psychological treatments for problem gambling and to determine if the effects can be sustained over time. It will also examine if different types of people respond better to certain types of psychological treatment.
Who can participate?
This study aims to recruit participants aged 18 years and above, wish to receive treatment for their gambling problem and can communicate in the English language. Individuals that are unable to provide informed consent, are at risk of self-harm or are currently receiving other treatments for their gambling problem or have received such treatment in the past 12 months from a counsellor or therapist are not able to participate in this study.
What does the study involve?
Participants will be randomly allocated to one of four treatment arms including cognitive- behavioural therapy, behavioural therapy, motivational interviewing and client-centred therapy. Participants will receive six individual sessions of face-to-face treatment with a psychologist. Information relating to the participants gambling activities, psychological profile and wellbeing will be collected immediately before and after treatment and at 6, 12, 18 and 24 months after the completion of treatment using telephone interviews.
What are the possible benefits and risks of participating?
Participants will receive free treatment for their gambling problems. The information obtained from this study may benefit people seeking help for their gambling problems in the future by informing treatment providers of effective interventions. The main risk involved in taking part in this study is possible distress associated with receiving any psychological intervention for a disorder of this kind.
Where is the study run from?
This study is being conducted by the Problem Gambling Research and Treatment Centre, a joint initiative of Monash University and the University of Melbourne. The study is led by Monash University Problem Gambling Research and Treatment Centre.
