Development and validation of the Gambling Follow-up Scale, Self-Report version: an outcome measure in the treatment of pathological gambling

Abstract

Objective: To validate the Gambling Follow-up Scale, Self-Report version (GFS-SR), a 10-item scale designed to assess gambling frequency, time and money spent on gambling, gambling craving, debts, emotional distress, family relationships, autonomy, and frequency of and satisfaction with leisure activities in individuals diagnosed with gambling disorder according to the DSM-5 criteria. Methods: One hundred and twenty treatment-seeking gamblers were evaluated, 84 of whom proceeded to treatment. Fifty-two relatives provided collateral informant reports at baseline. Six months later, the 50 patients who completed the program were reassessed. Results: The GFS-SR showed good inter-rater agreement and internal consistency. Factor analysis presented a three-factor solution: gambling behavior (factor 1); social life (factor 2); and personal hardship (factor 3). There was a high degree of convergence between GFS-SR scores and those of reference scales. The GFS-SR scores showed excellent sensitivity to change (factor 1), predictive validity for treatment response (factor 2), and ability to distinguish recovered from unrecovered patients after treatment (factor 3). A cutoff score of 33 was found to have 87% sensitivity and 80% specificity for gambling recovery. Conclusion: The GFS-SR is well suited to providing reliable follow-up of gamblers under treatment and assessing the efficacy of their treatment.

Demographic and psychiatric correlates of compulsive sexual behaviors in gambling disorder

“…The following gambling behaviors were evaluated using a self-report questionnaire adapted from the Addiction Severity Index (Petry, 2003): age at which the individual started to bet regularly (at least once per month), hours gambled each week, days gambled in the past month, money lost in the past month, and days in which the individual experienced gambling-related problems in the past month. The Portuguese version of this questionnaire exhibits good convergent validity with other measures of gambling severity (Galetti & Tavares, 2017).…”

Demographic, psychiatric, and personality correlates of adults seeking treatment for disordered gambling with a comorbid binge/purge type eating disorder

“…Each item is rated on a Likert scale of 0 to 4 points, with higher scores indicating more severe gambling symptoms. The Brazilian Portuguese version of the Gambling Symptom Assessment Scale has shown good convergent validity with other measures of gambling severity and is sensitive to change in treatment (Galetti & Tavares, ). The alpha from the present sample was α = .93.…”
