摘要:	【Introduction】 Both Internet addiction (IA) and self-harm are growing adolescents’ behavior problems in recent years. Previous studies have reported the comorbidity of IA and self-harm, but the comorbidity mechanisms remain unclear. 【Aims】 This study was aimed to investigate the comorbidity mechanisms of IA and Self-harm, by examining whether vulnerable personality traits would increase the risks for IA mediated through the Internet outcome expectancy as well as heightened the risks for self-harm mediated via the self-harm outcome expectancy among junior high school students. 【Methodology】 The cross-sectional design was taken. The participants were 601 junior high school students in Tainan, including 285 males and 316 females. All participate completed the Chen Internet Addiction Scale, Self-Harm Behavior Questionnaire, Internet Positive Outcome Expectancies Questionnaire, Self-injury Positive Outcome, and Expectancies Questionnaire, Shortened Chinese version of FFI. Data analysis was performed by using SPSS version 20.0, Structural Equation Modeling (SEM) was used to evaluate the hypothesized model for comorbidity mechanism of IA and self-harm. 【Results】 SEM results revealed that vulnerable personality traits directly and indirectly predicted the severity of IA, mediated through Internet outcome expectancy, and self-harm, mediated by self-harm outcome expectancy, respectively. The fitness of the model was adequate, and was able to explain 29.0% of the variance to IA and 33.6% of the variance to self-harm. 【Conclusions and imprecations】 Personality vulnerabilities may be the common etiology factor for both IA and self-harm, promoting the development of IA through Internet outcome expectancy and facilitating the risks for self-harm via self-harm outcome expectancy among adolescents. The results suggest for the prevention of IA and self-harm among junior high school students, mental health workers could consider to use vulnerable personality traits screening measures for identifying high risk groups. The results also provide a direction for designing cognitive-behavioral interventions in training effective emotion regulation and impulse control skills, as well as in decisional balancing strategies for cost-benefit of risky and healthy behaviors.
