Although adolescence is characterized by increasing individuation, parental support represents an important resource especially in early adolescence. This multi-informant study examined the role of parental self-efficacy in providing emotional and instrumental support when early adolescents partially learned from home during the COVID-19 pandemic. Based on a resources model of coping, we examined effects of parental self-efficacy on early adolescents' reports of self-regulated learning (SRL), learning self-efficacy, and positive emotions, mediated via early adolescents' problem-focused and emotion-focused coping. Assumptions were tested among 263 Austrian parent-child dyads. While the mediation assumption was rejected, we identified positive associations between emotional support and SRL, and between problem-focused coping and SRL, learning self-efficacy, and positive emotions. Instrumental support negatively related to SRL, suggesting benefits of emotional over instrumental support.
