Serious conduct problems in the children of adolescent mothers: disentangling confounded correlations

Early motherhood (less than 20 years of age) was found to be significantly correlated (r = .33) with the number of DSM-III symptoms of conduct disorder in a sample of 253 boys aged 6-13 years who had been referred to outpatient clinics. The following models were compared using path analysis: (a) Teenage motherhood, parental antisocial personality, and SES each contribute uniquely to the prediction of childhood conduct problems; (b) teenage motherhood mediates the association of SES and parental antisocial personality with child conduct problems; and (c) teenage motherhood is spuriously related with child conduct problems because of common associations with SES and parental antisocial personality. Model (c) best fit our data. Similar results were obtained whether maternal age at the birth of the firstborn child or the proband child was used to define maternal age and when teenage motherhood was defined as giving birth at less than 18 years.
