Area of Science:

  • Psychology
  • Behavioral Science
  • Clinical Psychology

Background:

  • Self-efficacy assessment is crucial for monitoring addictive behavior change and relapse prediction.
  • Existing instruments may not fully capture self-efficacy specific to gambling control.

Purpose of the Study:

  • To develop and validate the Gambling Self-Efficacy Questionnaire (GSEQ).
  • To assess perceived self-efficacy in controlling gambling behavior.

Main Methods:

  • A 42-item scale was administered to 309 adult gamblers.
  • A 16-item GSEQ was finalized based on psychometric properties.
  • Internal consistency, test-retest reliability, and factor structure were evaluated.

Main Results:

Related Experiment Videos

  • The GSEQ demonstrated high internal consistency (alpha =.96) and good test-retest reliability (r =.86).
  • Factor analysis supported a unitary factor structure.
  • GSEQ scores were negatively correlated with problematic gambling behavior, with problem gamblers scoring lower.

Conclusions:

  • The GSEQ is a psychometrically sound instrument for assessing gambling self-efficacy.
  • The GSEQ shows utility in treatment planning and outcome evaluation for problem gamblers.
