Livazović G, et al. - Researchers used the Canadian Adolescent Gambling Inventory with a sample of 366 participants, to determine the purposes of sociodemographic traits, family quality and risk behaviour in adolescent problem gambling, with attention on the psychological, social and financial outcomes from the socio-ecological model approach. On an individual level, a relationship level, as well as a community and societal level, the most crucial risk-protective factors in the development and maintenance of problem gambling were emphasized in this model. Significantly higher gambling results on all scales and significantly more risk behaviour was exhibited by the male participants. Significantly higher psychological outcomes of gambling, higher risk behaviour activity and lower family life satisfaction were reported by students with lower school success. Significant predictors of problem gambling identified in this study were age, gender, school success and the father’s education level. A greater risk was observed in older male adolescents who struggled academically and had lower educated fathers. A crucial link between adolescent gambling behaviour and very serious psychological, social and financial outcomes was identified. A high risk for problem gambling may be present in individuals having a constellation of risk factors.
