A randomized controlled trial of a personalized feedback intervention for problem gamblers.

Area of Science:

• Addiction Research
• Behavioral Psychology
• Public Health Interventions

Background:

• Personalized feedback is a promising self-help strategy for problem gamblers.
• Previous pilot tests and studies on other addictive behaviors suggest positive outcomes.
• This study evaluates the effectiveness and sustained efficacy of personalized feedback intervention materials for problem gamblers.

Purpose of the Study:

• To evaluate the effectiveness of personalized normative feedback for problem gamblers.
• To assess the sustained efficacy of personalized feedback interventions.
• To compare personalized normative feedback, partial feedback, and a waiting list control.

Main Methods:

• A randomized controlled trial was conducted with Ontario adults experiencing moderate to severe gambling problems.
• Participants were randomly assigned to receive full personalized normative feedback, partial feedback (without norms), or a waiting list control.
• The primary outcome measured was the reduction in gambling days at the six-month follow-up.

Main Results:

• No statistically significant impact was found for personalized normative feedback compared to the control group.
• Participants receiving partial feedback (without normative comparisons) showed a significant reduction in gambling days compared to the control group.
• The personalized feedback interventions were well-received by participants.

Conclusions:

• Personalized feedback interventions, particularly those without normative data, may help reduce gambling behavior.
• Brief interventions like this may have a limited, short-term impact on problem gambling severity.
• An internet-based version could provide accessible support and motivate individuals to seek further assistance.
