Objective:To explore the impact of family cohesion and adaptability on positive coping of adolescents with self-injurious behaviors, and the mediating role of self-efficacy in their relationships.Methods:From January 2023 to June 2025, a total of 123 adolescents with self-injurious behaviors from both the outpatient and inpatient departments of Bishan Hospital of Chongqing Medical University were assessed using the family adaptability and cohesion evaluation scale-Ⅱ(FACES-Ⅱ), simplified coping style questionnaire(SCSQ), and general self-efficacy scale(GSES). Descriptive and correlation analysis were conducted using SPSS 25.0 software, while AMOS 24.0 software was employed to construct and test a mediation model.Results:(1)The levels of family cohesion (51.00 (45.00, 60.00)), the family adaptability (34.50±8.88), positive coping (1.00 (0.67, 1.33)) and self-efficacy (23.39±8.23) among adolescents engaging in self-injurious behaviors demonstrated statistically significant positive correlation with each other ( r=0.276-0.795, P<0.01). (2) Family cohesion and adaptability directly predicted positive coping, with a direct effect of 0.291(95% CI=0.099-0.462, P<0.05) accounting for 73.12% of the total effect. Family cohesion and adaptability also indirectly predicted positive coping through self-efficacy, with an indirect effect of 0.107(95% CI=0.027-0.203, P<0.05) accounting for 26.88% of the total effect. The total effect was 0.398(95% CI=0.178-0.577, P<0.05). Conclusion:Family cohesion and adaptability can directly predict the positive coping behaviors among adolescents with self-injurious behaviors, and can also serve as indirect predictors of positive coping behaviors through the mediating role of self-efficacy.
