Purpose: With increased rates of marital breakdown it is important to identify the long-term mental health outcomes of marital problems and marital change for mothers and their children. Of particular interest is the possibility that mothers may benefit from leaving a relationship, but their children may not. This study examines the effects of marital quality and marital change on symptoms of depression in mothers and their children over 21 years. Method: Data (3,512 mothers and 3,334 children) were from Mater-University of Queensland Study of Pregnancy (MUSP), a population-based birth cohort study, which commenced in Brisbane, Australia, in 1981. Mothers and children were followed up at birth, 6 months and 5, 14 and 21 years after the initial interview. Marital status and marital quality were assessed at 5 and 14 years. Symptoms of depression were assessed in mothers and children at the 21-year follow-up. Results: A poor-quality marital relationship at the 14-year follow-up was associated with increased symptoms of depression in both mothers (+3.3 symptoms) and children (+1.1 symptoms) 7 years later. Symptoms of depression in the mother improved if she changed to unpartnered status (−1.31 symptoms); however, children experienced an increase in depression (+1.30 symptoms). There was a substantial increase in mothers' depression (+3.9 symptoms) associated with a poor reconstructed relationship but no change for children (0.68). Conclusion: Marital transitions may improve symptoms of depression in the mothers but not in their children. Clinical decisions for families living in some difficult marital relationships need to take into account the association between maternal and child mental health particularly evidence from clinical samples that remission of depression in the mother improves outcomes for the child.

Whether there is an independent association between problem behaviours and substance use disorders (SUD) needs further investigation. This study examined prospective associations of adolescent psychopathology and problem behaviours with SUD in early adulthood, and whether these associations are confounded by other factors. Data were from a prospective study of 2,429 young Australian adults from birth to the age of 21 when data on SUD were collected. Adolescent psychopathology and behaviour were assessed at 14 years via the Youth Self Report instrument on eight sub-scales of emotional and behavioural problems. In multivariate analyses, attention problems, delinquency, and aggression were associated with both single and multiple SUD in early adulthood, with delinquent behaviour being the strongest predictor (OR = 2.0, 95% CI 1.4–2.9 for one SUD and OR = 3.6, 95% CI 2.4–5.0 for multiple SUDs). Problem behaviours, in particular delinquency and aggression in early adolescence predict long-term SUD. The results suggest that substance use prevention programs should target adolescents with early symptoms of psychopathology and problem behaviour. [ABSTRACT FROM AUTHOR]
