Computerized cognitive training for problem gambling: A randomized controlled trial (TRAIN-online)

Area of Science:

• Psychology
• Behavioral Science
• Clinical Psychology

Background:

• Non-face-to-face interventions show promise for problem gambling.
• Cognitive training has potential but inconsistent efficacy in treating problem gambling.

Purpose of the Study:

• To evaluate a web-based cognitive training program targeting inhibition in adults with problem gambling.
• To compare the efficacy of cognitive training against a visuo-spatial control program.
• To assess changes in gambling severity, impulsivity, and quality of life.

Main Methods:

• A parallel, randomized, controlled, single-blinded trial was conducted.
• Participants (CPGI ≥5) were randomized 1:1 to cognitive training or a control program.
• Weekly phone calls supported engagement and transferability; outcomes measured at 6 and 14 weeks.

Main Results:

• No significant differences were found between the cognitive training and control groups for any outcome.
• Mean Problem Gambling Severity Index (PGSI) change at 6 weeks was -2.75 (intervention) vs. -2.44 (control).
• 34% of participants were no longer problem gamblers at 14 weeks; intervention acceptability was moderate.

Conclusions:

• Further research is needed to optimize cognitive interventions for problem gambling, improve engagement, and demonstrate added value.
• Minimal telephone interventions may be sufficient for some individuals with problem gambling.
• Objective, account-based gambling data are recommended for future studies.
