The correlation between non-suicidal self-injury and mobile phone social media dependence in adolescents

Objective: To explore the correlation between non-suicidal self-injury behavior and mobile social media dependence in adolescents, and to provide reference for intervention of non-suicidal self-injury. Methods: A total of 99 adolescents with non-suicidal self-injury behavior in our hospital from January 2022 to December 2023 were selected as the case group, and 97 healthy students were selected as the control group. Ottawa Self-injury Questionnaire, non-suicidal self-injury questionnaireand mobile phone social media dependence questionnaire were used for assessment, and Spearman correlation analysis was used to explore the correlation between the scores of Ottawa self-injury questionnaire, non-suicidal self-injury questionnaire and mobile phone social media dependence questionnaire. Results: The total score of mobile phone social media dependence questionnaire, conflict and withdrawal scores of the study group were higher than those of the control group, the difference was statistically significant . The scores of the functional subscale of the Ottawa non-suicidal self-injury questionnaire in the case group were higher than those in the control group, and the difference was statistically significant. The scores of the five factors in the functional subscale of the Ottawa non-suicidal self-injury questionnaire , internal emotion regulation, social influence, external emotion regulation, sensation seeking and addiction characteristics, were positively correlated with the scores of the five factors in the mobile phone social media dependence questionnaire, salience, social promoting, compulsive, conflict and withdrawal (r=0.155-0.442). The scores of non-suicidal self-injury questionnaire were positively correlated with the conflict, withdrawal and total scores of the mobile phone social media dependence questionnaire (r=0.145-0.209). The factors influencing non-suicidal self-injury include education level, conflict. Conclusion: There is a correlation between non-suicidal self-injury and mobile phone social media dependence in adolescents, which provides reference for the treatment of non-suicidal self-injury in the future.
