Harsh parenting trajectories from childhood through adolescence and socioemotional competences at age 18: 2004 Pelotas Birth Cohort Study.

Background: Limited research has explored the course of harsh parenting practices throughout childhood and adolescence and its impact on socioemotional competences from a longitudinal perspective. This study examined the association between harsh parenting trajectories and socioemotional competences at age 18.

Methods: Data from the 2004 Pelotas (Brazil) Birth Cohort study, originally comprising 4231 live births, were used. Harsh parenting was measured using the parent-report version of the Parent-Child Conflict Tactics Scale at ages 6, 11, 15 and 17 years, and trajectories were identified using a group-based modelling approach. Socioemotional competences were emotion regulation, assessed by the Emotional Regulation Index for Children and Adolescents; self-esteem, measured by the self-report Rosenberg Self-esteem Scale; prosocial behaviour and peer relationship problems, both assessed by the Strengths and Difficulties Questionnaire. Multivariate linear and Poisson regression models were applied to examine the effects of harsh parenting trajectories on socioemotional competences, adjusting for confounding variables.

Results: We identified three trajectories: a "low harsh parenting" trajectory (49.7 %), a "moderate harsh parenting" (44.7 %), and a "high harsh parenting" trajectory (5.6 %). Compared to those belonging to the low harsh parenting trajectory group, adolescents who experienced either a moderate or high harsh parenting trajectory exhibited lower scores in emotion regulation, self-esteem, and prosocial behaviour scales, along with higher scores of peer relationships problems.

Limitations: Data on harsh parenting at 15 and 17 years were available only for a sub-sample.

Conclusions: Our study extends the evidence of the adverse effects of persistent harsh parenting on socioemotional competences during adolescence.
