Behavioral Intention to Gamble Among Adolescents: Differences Between Gamblers and Non-gamblers-Prevention Recommendations.

Gambling is a rapidly growing phenomenon among adolescents associated with negative psychosocial effects. To prevent this public health problem, it is necessary to identify the factors that cause and maintain adolescent gambling. Based on the theory of planned behavior (TPB), structural equation models were used in a sample of 1174 adolescents (aged 12-20 years) to study the effect of attitudes, subjective norms and self-efficacy on gambling intention in adolescent gamblers (n = 432) and non-gamblers (n = 742). Measurement invariance was assessed and then structural model was tested separately in gamblers and non-gamblers. The influence of past gambling experience on the TPB model was also studied through multigroup analysis. All models showed adequate fit to the data. The relationships between attitudes and self-efficacy with gambling intention were significantly stronger in gamblers subsample. These results confirmed that gambling experience increases the predictive ability of the TPB model in gamblers. TPB independent variables explained 16.2% of variance of gambling intention in non-gamblers and 32.4% in gamblers. Subsequently, the TPB model for gamblers explained 19% of variance of gambling frequency. In this last model, gambling intention partially mediates the influence of self-efficacy on gambling behavior. The subjective norm was the variable with the greatest effect on gambling intention in non-gamblers, while self-efficacy to control gambling was the exogenous variable with greatest effect on gambling frequency. The findings suggest the possibility of specific gambling prevention in adolescent gamblers and non-gamblers.
