摘要:AbstractThe aim of this study was to determine the effects of inter-parental conflict on college student's self-efficacy. This cross-sectional study was conducted on 374 randomly selected college students of Medical Science University aged 17 to 19 years old in Hamadan, Iran. The Inventory of Children's Perception of Inter-parental Conflict Scale and the General Self-Efficacy Scale were used. Results of Pearson correlation coefficient indicated that low inter-parental conflict had positive significant correlation with high students’ self-efficacy, while high inter-parental conflict had negative correlation with low self-efficacy (p<.05). The result of the study also showed that within CPIC subscales perception of threat to self had highest negative relationship with self-efficacy, followed by conflict properties and self blame. Moreover, results implied that self-efficacy among late adolescents can be improved through positive parents relationship and parents-adolescent relationship (p<.05). Thus, it is suggested that parents prepared with appropriate knowledge and skills for their adolescent's needs and development.
