Abstract

Gambling urges and gambling refusal self-efficacy beliefs play a major role in the development and maintenance of problem gambling. This study aimed to translate the Gambling Urge
Scale (GUS) and the Gambling Refusal Self-Efficacy Questionnaire (GRSEQ) from English to
Italian (GUS-I, GRSEQ-I) and to test their factor structure, internal consistency, construct
validity, concurrent validity, and gender differences in 513 individuals from the Italian
community. Factor structure and construct validity were tested through Confirmatory Factor
Analysis, internal consistency through Cronbach’s alpha, concurrent validity through correlations with gambling-related cognitions (GRCS-I), probable pathological gambling (SOGS-I),
and gambling functioning (GFA-R-I). Results confirmed that the 6 items of the GUS-I load
highly on one dimension of Gambling Urge, and each of the 26 items of the GRSEQ-I load
highly on their relevant sub-dimension, among the following: situations/thoughts, drugs,
positive emotions, negative emotions. Both scales are internally consistent and show concurrent validity with gambling-related cognitions, probable pathological gambling, and gambling
functioning. Males score higher than females at the GUS-I; females score higher than males at
the GRSEQ-I. The findings from the present study suggest that the GUS-I and the GRSEQ-I
are internally consistent and valid scales for the assessment of gambling urges and gambling
refusal self-efficacy in Italian individuals from the community, with significant repercussions
in terms of assessment, prevention, and intervention.
