【摘要】 目的:调查医学生中自伤行为的现状,探讨其与手机依赖和抑郁症状的关联性。方法:在某医科大学选取2376名大一至大三年级学生作为研究对象,通过询问调查条目"最近一年是否做过以下8种故意伤害自己的行为"来评定自伤行为,使用青少年手机使用依赖自评问卷(SQAPMPU)和抑郁自评量表(SDS)对大学生手机依赖行为和抑郁症状进行评估。结果:医学生自伤行为的检出率为12.9%(307/2376)。有手机依赖行为和抑郁症状的医学生中,自伤行为的检出率(17.9%vs.11.0%;21.1%vs.11.0%)更高(P<0.001);医学生手机依赖(OR=1.74)、抑郁症状(OR=2.05)均与自伤行为呈正向关联,并对自伤行为存在相乘交互作用(OR=2.31),但不存在相加交互作用[RERI=0.33(95%CI:-2.17~2.83)、AP=0.12(95%CI:-0.70~0.94)及Index S=1.22(95%CI:0.28~5.38)]。结论:自伤行为在医学生中的发生率较高;手机依赖和抑郁症状与自伤行为正向关联,并对自伤行为存在相乘交互作用。更多还原

【Abstract】 Objective:To explore the prevalence of self-harm and its relation to mobile phone dependence and depressive symptoms in medical college students. Methods: A total of 2376 students involved freshman,sophomore and junior were recruited from a medical university. Their self-harm behavior was assessed with a question of ’Have you ever harmed yourself in a way that was deliberate but not intended as a means to take your life in the last year?". The Self-rating Questionnaire for Adolescent Problematic Mobile Phone Use and Self-rating Depression Scale were applied to measure mobile phone dependence and depressive symptoms. Results: The self-reported rate of self-harm was 12. 9%( 307 /2376). The students with mobile phone dependence and depressive symptoms reported higher rates of self-harm( 17. 9% vs. 11. 0%,21. 1% vs. 11. 0%; P < 0. 001). Mobile phone dependence and depressive symptoms were positively related to self-harm( OR = 1. 74,2. 05),the multiplicative interaction between mobile phone dependence and depressive symptoms on self-harm was significant( OR = 2. 31),but the additive interaction was not significant. The value of three indicators referred to RERI,AP and Index S were 0. 33( 95% CI:- 2. 17- 2. 83),0. 12( 95% CI:- 0. 70- 0. 94) and 1. 22( 95% CI: 0. 28- 5. 38). Conclusion: The results show that the prevalence of self-harm is higher in medical college students. Mobile phone dependence and depressive symptoms are related to self-harm in medical college students,respectively. The multiplicative interaction between mobile phone dependence and depressive symptoms on self-harm is significant.更多还原
