A Meta-analysis of Brief Personalized Feedback Interventions for Problematic Gambling

Area of Science:

• Behavioral Psychology
• Clinical Psychology
• Public Health

Background:

• Personal Feedback Interventions (PFIs) are common tools to decrease gambling behaviors.
• PFIs provide personalized gambling data, often compared to peer groups.

Purpose of the Study:

• To review and meta-analyze the efficacy of PFIs.
• To examine intervention content, delivery, samples, and moderators of efficacy.

Main Methods:

• Systematic review and meta-analysis of 11 studies involving 16 PFIs.
• Exploration of six potential moderators influencing intervention effectiveness.

Main Results:

• PFIs demonstrated a small, statistically significant effect (d = 0.20) compared to control groups.
• Efficacy was higher for individuals with greater gambling severity, those receiving educational information, and when combined with motivational interviewing.
• Reduced efficacy was observed with in-person feedback lacking motivational interviewing or when participants were informed of their psychological measure scores.

Conclusions:

• PFIs are a cost-effective harm-reduction strategy for gambling.
• Optimizing PFI efficacy involves targeting severe cases and integrating them with motivational interviewing and educational components.
• Greater therapeutic effects may be achieved when PFIs are part of a broader treatment plan.
