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.

Objective To investigate the differences between subjective and objective sleep quality in recurrent depressive patients and the correlative factors. Methods Thirty-two cases of recurrent depressive patients(the recurrent group) and 32 cases of first episode depressive patients(the control group)who met the inclusion were recruited in this study. The subjectivesleep quality ,mood and objective sleep quality of patients were estimated by Pittsburgh sleep quality index(PSQI),Hamilton anxiety Scale(HAMA),Hamilton depression Scale(HAMD),respectively. O ne whole-night polysomnography (PSG) was recorded. Results On subjec-tivesleep quality,the total sleep time was shorter,the sleep latency was longer,and the sleep efficiency was lower in the recurrent group compared with the control group. On objectivesleep quality ,the wake times were increased , the NREM1 phase was longer,the NREM2 phase was shorter,the RME phase was longer,the proportion of REM phase was increased,and the latency of REM phase was shorter in the recurrent group compared with the control group(P<0.05,respectively). There were significant differences between the subjective and objective sleep quali-ty in both groups,while the differences in the recurrent group were more significant(P < 0.01). In the recurrent group,thedifference of the total time between the subjective and objective sleep was positively correlated with PSQI score,the duration of disease and the number of attacks(P < 0.05),while,the differences of the sleep latency and sleep efficiency between the subjective and objective sleep were both positively correlated withPSQI score and the HAMA-14 score,respectively(P<0.05). Conclusion There was a significant difference between the subjec-tive and objective sleep quality of patients with recurrent depression ,and the differences were related to the course of disease,the number of attack,PSQI score and HAMA-14 score.
