The relationship between negative peer relationship and non-suicidal self-injury in Chinese adolescents: A moderated-mediation model

Abstract

ObjectiveThe objective of the study was to investigate the mediating effect of regulatory emotional self-efficacy (RESE) between negative peer relationship and non-suicidal self-injury (NSSI), as well as the moderating effect of gender difference.MethodsA study of 578 Chinese adolescents (46.9% males, mean age = 16.32 years, SD =0.54) was conducted using the Child and Adolescent Peer Relationship Inventory, Regulatory Emotional Self-Efficacy Scale, and the Adolescent Self-Injury Questionnaire.ResultsNegative peer relationship was positively correlated with NSSI, and RESE was negatively correlated with negative peer relationship and NSSI. RESE mediated the association between negative peer relationship and NSSI. The first stage(predicting the effect of negative peer relationship on RESE) and the second stage (predicting the effect of RESE on NSSI) of the mediation effect of RESE were both moderated by gender. Specifically, compared with boys, the effect of negative peer relationship on RESE was stronger for girls, and the effect of RESE on NSSI was stronger for girls than boys.ConclusionNegative peer relationships may influence NSSI of adolescents through the mediating effect of RESE and the moderating role of gender.

The Effect of Bullying Victimization on Adolescent Non-Suicidal Self-Injury: The Mediating Roles of Alexithymia and Self-Esteem

“…The questionnaire has been used by past studies in measuring NSSI among Chinese adolescents and shows excellent reliability and validity in the populations. 70 In the present study, the Cronbach’s α of NSSI was 0.94.…”

The Characteristics and Influencing Factors of Nonsuicidal Self-Injury of Adolescents With Depressive Disorder in China

“…After data collation, three or more articles on gender, age, residence, and whether they were solitary were investigated in the same form. The mean age of each study was 10 to 22 years, 13 to 18 years, 12 to 20 years, 13 to 20 years, and 13 to 25 years, and the number of subjects with NISS and non-NISS was 18/21, 93/19, 90/70, 90/139, and 230/130, and the NOS score was 6, 7, 6, 7, and 8 (Li, 2021a; Li, 2021b; Liu, 2020; Wen, 2020; Xu, 2021). The quality of the included studies was good, as shown in Table 1.…”

“…A total of 16 articles entered the second stage of evaluation. After full-text reading, two articles older than 22 years, five articles including other mental disorders, and two articles due to other discrepancies were excluded, and five articles were finally included (Li, 2021a;Li, 2021b;Liu, 2020;Wen, 2020;Xu, 2021) (see Fig. 1).…”

“…One article mentioned the site of self-injury; more than 80.0% of the respondents' site of self-injury was the upper limb; the remaining patients' sites of self-injury were the lower leg and ankle, scalp, and abdomen (Li, 2021a). Four articles mentioned the mode of self-injury, and the top four modes of self-injury were sharp cutting the skin, scratching until bleeding, impinging on harder things, and biting (Li, 2021a;Li, 2021b;Liu, 2020;Xu, 2021).…”

“…After data collation, three or more articles on gender, age, residence, and whether they were solitary were investigated in the same form. The mean age of each study was 10 to 22 years, (Li, 2021a;Li, 2021b;Liu, 2020;Wen, 2020;Xu, 2021). The quality of the included studies was good, as shown in Table 1.…”
