Аннотация

Effortful control was investigated in 302 children aged 23–139 months (52% boys) using laboratory-based experimental tasks. We have adapted behavioral batteries developed by Kochanska and colleagues for children aged 22–78 months and developed comparable batteries for older preschoolers and primary school children. Results showed good interrater reliability for observational ratings, as assessed using intraclass correlations and kappas. An examination of the dimensional structure of the observational measures using con-firmatory factor analyses indicated that in the youngest age group (22–45 months) effortful control has a two-factor structure, including Delaying and Motor Control; in middle and older preschool, the component of Suppressing/Initiating Activity emerged. In the primary school years, task measures were not correlated with each other. We evaluated discriminant validity of observational measures with respect to gender and age. There were few significant gender effects whereas age effects were significant for nearly all variables. Age differences suggest the developmental trajectories of effortful control and its components, delaying, control of gross and fine motor activity, suppressing dominant activity and initiating subdominant activity to signal, and effortful attention. In light of the existing literature, these findings are discussed in terms of the structure and development of in Russian children between early childhood and school years.
