Unpacking the linkages between single parent households and early adolescent adjustment.

Living with an unmarried mother is consistently associated with adjustment issues in adolescence, but these associations can vary by both time and place. Following life course theory, this study applied inverse probability of treatment weighting techniques to data from the National Longitudinal Survey of Youth (1979) Children and Young Adults study (n = 5,597) to estimate various treatment effects of family structures through childhood and early adolescence on internalizing and externalizing dimensions of adjustment at age 14. Young people who lived with an unmarried (single or cohabiting) mother during early childhood and adolescence were more likely to drink and reported more depressive symptoms by age 14 than those with a married mother, with particularly strong associations between living with an unmarried mother during early adolescence and drinking. These associations, however, varied according to sociodemographic selection into family structures. They were strongest for youth who more closely resembled the average adolescent living with a married mother.
