Abstract

This study aimed at identifying the heterogeneous trajectories of emotional dysregulation across childhood and to study the relationship between specific trajectories and adolescent suicide-related behaviour (SRB). Data from the Millennium Cohort Study (N = 13,853 children; 49.07% female, M = 3.13 years at baseline, SD = 0.2) were used to identify the emotional dysregulation trajectories from 3 to 8 years old, using growth mixture modelling. Moreover, 1992 participants (52.86% female) from the initial sample were used to study the relationship between childhood emotional dysregulation trajectory and engagement in both self-harm and suicide attempt at age 17, using logistic regression. Some other time-invariant and proximal (adolescent) risk factors were incorporated into this analysis. Six emotional dysregulation trajectories were identified. Self-harm at age 17 was significantly associated with the history of self-harm and other proximal factors, but not with emotional dysregulation trajectory membership. Childhood trajectories featured by earlier emotional dysregulation were associated with higher risk of lifetime suicide attempt, as well as other proximal factors (concurrent self-harm). This study found differential risk profiles involved in both SRB forms. A relationship between early emotional dysregulation and suicide attempt engagement in adolescence was identified. Early interventions should be developed to deal with SRB risk factors from childhood.
