Abstract
Several developmental theories identify caregiver emotion socialization (ES) as predicting multiple child psychological outcomes, including anxiety. The present study delineated developmental trajectories of mothers' ES practices, specifically the initial levels and growth across time of their supportive and nonsupportive responses to their young children's emotions. To contextualize the developmental role of these processes, we examined multiple predictors (i.e., maternal emotion dysregulation, child negative emotionality, demographic covariates) and one outcome (i.e., child anxiety) of ES trajectories, as well as how trajectories varied by emotion type-sadness, anger, or worry. We investigated these questions in a community sample of 173 predominantly White, non-Hispanic mother-child dyads who participated at four time points when children were aged 2-5 years, with assessments 1 year apart. Mothers reported on study variables. Results varied by ES type. Mothers' supportive global and emotion-specific ES were highly stable across time and did not relate to predictors, outcomes, or demographic covariates. Mothers endorsed gradual decreases in nonsupportive ES across time, with some variations across emotion type. Nonsupportive responses to worry and sadness each comprised two classes varying by intercept and slope. Nonsupportive worry responses linearly decreased, whereas nonsupportive sadness responses linearly increased. Across global and emotion-specific models, maternal emotion dysregulation, child negative emotionality, and demographic covariates showed unique relations with nonsupportive ES intercept and slope. Trajectories were mostly unrelated to later child anxiety, with the exception of class-specific differences for nonsupportive worry responses. Implications and future directions are discussed.
