This study investigated potential heterogeneity in development among offspring (age 17) of teen mothers and maternal life course as correlates of variation. Using latent class analysis, subgroups of developmental outcomes were identified. Maternal standing in two life course realms (i.e., socioeconomic and domestic) was considered as a potential explanation for heterogeneity in offspring's development. Offspring reported on measures assessing their psychological, academic, and behavioral development. Teen mothers reported on measures of life course realms. Three subgroups of developmental outcomes were identified: on track (52%), at risk (37%), and troubled (11%). Findings suggest that economic hardship and number of pregnancies among teen mothers distinguish developmental patterns among teenage offspring, whereas teen mothers' educational attainment and marital status do not.
