【摘要】 目的 探讨述情障碍对非自杀性自伤（NSSI）青少年自伤成瘾的影响及内部情绪调节在其中的中介作用，旨在为降低NSSI青少年自伤成瘾提供参考。方法 选取2021年12月至2022年8月在重庆医科大学附属第一医院精神科门诊和住院部就诊的有NSSI行为的123例青少年为研究对象。采用渥太华自伤行为问卷（OSI）中的功能分量表、成瘾分量表以及多伦多述情障碍量表（TAS-20）调查NSSI原因、自伤成瘾以及述情障碍情况，采用Pearson相关分析3者之间的相关性。采用Process插件和Bootstrap法对内部情绪调节在述情障碍与自伤成瘾之间的中介效应进行分析和检验。结果 123例NSSI青少年的TAS-20总分为（68.70±11.17）分，功能分量表中内部情绪调节维度得分为（19.32±6.02）分，社交影响维度得分为（15.29±6.24）分，外部情绪调节维度得分为（10.04±2.96）分，寻求刺激维度得分为（6.30±3.21）分，成瘾分量表得分为（20.26±8.16）分。不同性别、是否是独生子女NSSI青少年的TAS-20总分比较，差异有统计学意义（t=-2.64、-2.84;P<0.01）。不同父母婚姻状况的NSSI青少年的成瘾分量表得分比较，差异有统计学意义（t=-2.03,P<0.05）。TAS-20与功能分量表中的内部情绪调节、社交影响、外部情绪调节、寻求刺激维度得分和成瘾分量表得分呈正相关（r=0.24～0.58,P<0.01）。NSSI青少年的内部情绪调节在述情障碍和自伤成瘾之间的部分中介作用显著，占总效应的46.34%。结论 NSSI青少年自伤成瘾可能与内部情绪调节和述情障碍有关，内部情绪调节在述情障碍和自伤成瘾间起部分中介作用。更多还原

【Abstract】 Objective To explore the influence of alexithymia on self-injury addiction of non-suicidal self-injury(NSSI) adolescents and the mediating role of internal emotional regulation in it, so as to provide reference for reducing self-injury addiction of NSSI teenagers. Methods A total of 123 adolescents diagnosed as NSSI in psychiatric outpatient department and inpatient department of the First Affiliated Hospital of Chongqing Medical University from December 2021 to August 2022 were recruited. The subscales of function and addiction of Ottawa Self-injury Inventory(OSI) and 20-Item Toronto Alexithymia Scale(TAS-20) were applied to investigate the cause of NSSI, self-injury addiction, and alexithymia. Pearson correlation analysis was used to analyze the correlation among the three. The mediating effect of internal emotion regulation between alexithymia and self-injury addiction was analyzed and tested using the Process plug-in and Bootstrap method.Results The total score of TAS-20 in 123 NSSI adolescents was(68.70±11.17), the score of the functional subscale was(19.32±6.02), the social influence was(15.29±6.24), the external emotional regulation was(10.04±2.96), the stimulation seeking was(6.30±3.21), and the score of the addiction subscale was(20.26±8.16). There was a statistically significant difference in the total TAS-20 scores among NSSI adolescents of different genders and whether they were only children(t=-2.64,-2.84; P < 0.01). The comparison of addiction subscale scores among NSSI adolescents with different parental marital status showed statistically significant differences(t=-2.03, P < 0.05). The score of TAS-20 was positively correlated with internal emotion regulation, social influence, external emotion regulation, stimulus-seeking dimension scores and addiction subscale score(r=0.24-0.58, P < 0.01). The internal emotional regulation of NSSI adolescents has a significant mediating effect between alexithymia and self-injury addiction, accounting for 46.34% of the total effect. Conclusions NSSI adolescent self-injury addiction may be related to internal emotional regulation and alexithymia, and internal emotional regulation plays a partial mediating role between alexithymia and self-injury addiction.更多还原
