Perceived discrimination, loneliness, and non-suicidal self-injury in Chinese migrant children: The moderating roles of parent-child cohesion and gender

Abstract

Chinese rural-to-urban migrant children frequently experience discrimination, which thereby often results in significant negative consequences. However, little is known about the contribution of perceived discrimination experiences to non-suicidal self-injury (NSSI). This study aimed to examine the relationship between perceived discrimination and NSSI, the mediating role of loneliness in this relationship, and the moderating roles of parent-child cohesion and gender. Six hundred fifty-seven migrant children completed a perceived discrimination scale, an NSSI questionnaire, a loneliness scale, and a parent-child cohesion inventory. Results showed that there was a significant positive association between perceived discrimination and NSSI among migrant children. Loneliness mediated the relationship between perceived discrimination and NSSI. Moreover, parent-child cohesion demonstrated a moderating effect on the mediation via loneliness; the indirect association between perceived discrimination and NSSI via loneliness was only significant in low parent-child cohesion condition, but not in the high condition. Additionally, there were differences by gender, with a significantly stronger mediating effect of loneliness among migrant girls compared with migrant boys. The findings from this study contribute to the understanding of the underlying mechanisms in the relationship between perceived discrimination and NSSI. Discussion also provides directions for future interventions and delineate how programs could be designed to target loneliness and parent-child cohesion among migrant children.
