Background Non-suicidal self-injury (NSSI) is a prevalent behavioural health concern during adolescence and has been consistently linked to emotionally invalidating interpersonal environments. Aims This study tested whether distress tolerance and negative urgency prospectively explained the link between invalidating environments and adolescent NSSI. Method The study used a 2-wave longitudinal design with a 6-month interval; 300 Iranian adolescents (70% female, aged 13–17 years) participated. Results Cross-lagged panel modelling showed that invalidating environments at wave 1 predicted higher NSSI at wave 2, when we controlled for baseline NSSI, and were associated with increases in negative urgency. Although both negative urgency and distress tolerance were related to later NSSI, only negative urgency significantly mediated this relationship; distress tolerance and the hypothesised serial pathway did not show significant associations. Sensitivity analyses indicated developmental differences across age groups. Conclusions The findings highlight impulsive response under distress as a central mechanism linking environmental invalidation to adolescent NSSI and identify negative urgency as a key intervention target.
Background Non-suicidal self-injury (NSSI) is a major public health concern during adolescence, yet relatively little is known about whether daily exposure to natural environments is prospectively associated with adolescents’ self-reported NSSI frequency. This study examined the longitudinal association between nature...

Empirical evidence increasingly supports an association between non-suicidal self-injury (NSSI) and social anxiety symptoms among Chinese adolescents, although their temporal relationship remains inadequately established. To address this gap, the present study employed a cross-lagged panel design to examine the longitu...

Background Childhood maltreatment is associated with adolescent non-suicidal self-injury (NSSI), but the roles of depressive symptoms and physical activity remain unclear. We examined these relationships using variable-level and network approaches. Methods This cross-sectional study included 2,354 adolescents recruited...

Background Non-suicidal self-injury (NSSI) is a growing concern among adolescents, yet the emotional mechanisms underlying this behavior remain insufficiently understood. Emotional reactivity—including sensitivity, intensity, and persistence—may be associated with NSSI through its relationship with adolescents’ capacit...

It is suggested that early identification and prevention of NSSI among adolescents should consider both external stressors, such as punishment-related stress, and internal regulatory vulnerabilities, particularly limited access to effective emotion regulation strategies.

Background Despite growing recognition of non-suicidal self-injury (NSSI) as a potential behavioral addiction, the sequential mechanisms linking childhood trauma to NSSI addiction remain unclear. This study examined a serial mediation model testing whether trait impulsivity and depressive symptoms sequentially mediate...
