Low-income mothers' patterns of partnership instability and adolescents' socioemotional well-being.

The present study investigated the association of family structure and maternal partnership instability patterns with adolescents' behavioral and emotional well-being among urban low-income families. Analyses employed data from the Three-City Study to track maternal partnerships over the youth's life span, linking longitudinal family structure and transition patterns to adolescent well-being (N = 2305). Families were classified into nine mutually exclusive longitudinal partnership groups based on current status at wave 3 (single, married, or cohabiting) and the longevity of that status: always (since adolescent's birth with no transitions), stable (lasting two years or more, preceded by transitions), or new (transpiring in the past 2 years). Adolescents in the always married group displayed less delinquency and externalizing problems, according to both youth and mother reports, than peers in always single-parent or newly married households. In contrast, youth in always cohabiting households had higher maternal ratings of internalizing problems and youth with newly cohabiting mothers reported higher psychological distress than peers in similar stability groups with single or married mothers. Overall, several potential explanatory processes for the family structure and stability patterns surfaced: married parent families reported less economic hardship, more family routines and father involvement, and less maternal psychological distress and parenting stress than their single and cohabiting counterparts. Policy implications of these findings are discussed. (c) 2012 APA, all rights reserved.
