童年创伤在手机依赖与抑郁情绪关联中的中介效应

Mediating effect of childhood trauma in the association of mobile phone dependence and depression

目的探讨手机依赖与抑郁情绪之间的关系及童年期创伤在二者之间的中介作用。方法应用手机依赖量表(MPAI)、抑郁自评量表(SDS)、童年期创伤问卷(CTQ-SF),采用方便抽样的方法于2019年2~5月对404名微信用户在线发放问卷进行调查。结果 (1)404名被试CTQ-SF因子中情感虐待发生率为7.4%,躯体虐待发生率为7.2%,性虐待发生率为7.7%,情感忽视发生率为19.3%,躯体忽视发生率为28.5%;(2)抑郁水平高的人群在CTQ-SF和MPAI得分上显著高于抑郁水平低的人群(F=56.708,P<0.001;F=8.944,P<0.001);(3)CTQ-SF中情感虐待、躯体虐待、性虐待、情感忽视、躯体忽视5项因子的得分与手机依赖和抑郁情绪得分均呈显著正相关;(4)手机依赖对抑郁的直接预测作用显著(β=0.17,P<0.001);加入童年期创伤作为中介变量后,手机依赖仍能显著预测抑郁(β=0.17,P<0.001),童年期创伤中介效应所占比例为34.62%。结论手机依赖程度越高、童年创伤经历越多、抑郁情绪越明显;手机依赖、童年期创伤、抑郁情绪三者之间呈显著正相关且童年期创伤起部分中介作用,手机依赖程度能有效预测抑郁水平的高低,童年期创伤影响抑郁情绪的发生。

Objective To explore the relationship between mobile phone dependence and depression, and the mediating role of childhood trauma between them.Methods The mobile phone dependence scale(MPAI), the depression self-rating scale(SDS), and the childhood trauma questionnaire(CTQ-SF) were used. Convenient sampling was used to issue online questionnaires to 404 WeChat users from February to May 2019.Results(1)Among the 404 subjects, the incidence of emotional abuse in the CTQ-SF factor was 7.4%;the incidence of physical abuse was 7.2%;the incidence of sexual abuse was 7.7% people;the incidence of affective neglect was 19.3%;the incidence of somatic neglect was 28.5%;(2)People with high levels of depression had significantly higher CTQ-SF and MPAI scores than depression people with low levels(F=56.708, P<0.001;F=8.944, P<0.001);(3)The scores of the five factors of emotional abuse, physical abuse, sexual abuse, emotional neglect and physical neglect in CTQ-SF and cell phone dependence and depression emotion scores were significantly positively correlated;(4)Mobile phone dependence had a significant direct predictive effect on depression(β=0.17, P<0.001);after childhood trauma was added as a mediating variable, mobile phone dependence could still significantly predict depression(β=0.17, P<0.001), the mediating effect of childhood trauma was 34.62%.Conclusion The higher the degree of mobile phone dependence and the more childhood trauma experiences, the more obvious the depression. There was a significant positive correlation between mobile phone dependence, childhood trauma and depression, and childhood trauma plays a part of the mediating role. Mobile phone dependence can be effective predict the level of depression, childhood trauma affects the occurrence of depression.
