Purpose: The purpose of the study was to investigate the personal, familial, and environmental variables that affect low level gambling behavior in university students. Methods: The participants were 389 students in 4 universities. Data were obtained from these participants through self-report questionnaires, administered between August 19 and September 13, 2013 and data were analyzed using the SPSS/WIN 19.0 programs. Results: The significant predictors of low level gambling behavior in university students were self-control, family strengths, social motives, amusement motives, number of gambling peers, onset of gambling, irrational gambling beliefs, gambling experience of father, mother and peers, and risk taking. These personal, familial and environmental variables explained 65.5% of the variance in low level gambling behavior. Conclusion: The outcomes of this study indicate that, for university students to decrease gambling behavior, intervention programs that manage gambling experience of family and peers should be developed with an emphasis on decreasing irrational gambling beliefs, social motives, amusement motives, and risk taking behavior and increasing self-control and family strengths.
