First grade emotion knowledge as a predictor of fifth grade self-reported internalizing behaviors in children from economically disadvantaged families.

In this longitudinal study, we examined the relations between emotion knowledge in first grade, teacher reports of internalizing and externalizing behaviors from first grade, and children's self-reported internalizing behaviors in fifth grade. At Time 1, we assessed emotion knowledge, expressive vocabulary, caregiver-reported earned income, and teacher-rated internalizing and externalizing behaviors in 7-year-old children from economically disadvantaged families (N = 154). At Time 2, when the children were age 11, we collected children's self-reports of negative emotions, depression, anxiety, and loneliness. First grade teacher-reported externalizing behaviors, but not first grade internalizing behaviors, were positively related to children's self-reports of internalizing behaviors in fifth grade. First grade emotion knowledge accounted for a significant amount of variance in children's self-reports of internalizing symptoms 4 years later, after controlling for per capita earned income, expressive vocabulary, and teacher-reported internalizing and externalizing behaviors in first grade.
