OBJECTIVE: : There is now emerging epidemiological evidence that a substantial proportion of toddlers in the general population may be experiencing a significant opposition-defiance problem before 2 years of age. This article describes the continuity and discontinuity in boys' and girls' opposition-defiance statuses during toddlerhood. METHOD: : Data came from The Québec Longitudinal Study of Child Development, a survey of a representative birth cohort of children from the Canadian province of Québec. A time-specific latent variables (Markov) model was used to estimate the proportion of toddlers who cease or start to exhibit oppositional-defiant behaviors (ODBs) on a frequent basis between 17 and 29 months of age and to test for gender differences therein. RESULTS: : A majority of toddlers who had exhibited ODBs on a frequent basis at 17 months of age were still doing so 1 year later. Also, a majority of toddlers who did exhibit ODBs on a frequent basis at 29 months of age had done so 1 year earlier. The results also show that there are more toddlers who start than stop exhibiting ODBs on a frequent basis during this period. Further, the continuity and discontinuity in toddlers' opposition-defiance statuses during this period did not vary between boys and girls, suggesting that gender differences in opposition-defiance have not yet emerged by the second half of the third year of life. CONCLUSION: : The predictive accuracy of early opposition-defiance is very good, with a substantial proportion of toddlers experiencing a significant opposition-defiance problem throughout toddlerhood. |
