The author investigated whether adverse effects of single parenthood not observed in 6-7-year-old NLSY (National Longitudinal Study of Youth) children might emerge when they reached 12-13 years of age. Outcomes included mathematics, reading, vocabulary scores, and behavior problem ratings. Little or no evidence of systematic negative effects emerged at the later age except for some isolated findings in the Black sample that suggested that vocabulary scores were somewhat negatively influenced by years of single-parent experience and positively affected by extended 2-parent experience. The general absence of adverse effects, as well as the minimally significant relationships found in the Black sample, may be explained in terms of the role played by maternal education and ability. The findings suggest that the presence of positive maternal attitudes and parenting resources may significantly mitigate the likelihood of adverse child outcomes of single parenthood.
