A moment of autonomy support brightens adolescents' mood: Autonomy support, psychological control and adolescent affect in everyday life

This experience sampling study examined whether autonomy-supportive and psychologically controlling interactions with parents are intertwined with adolescents' momentary affect. For 7 days (in 2020), 143 adolescents (Mage = 15.82; SDage = 1.75; 64% girls; 95% European, 1% African, 3% unknown) reported 5 or 6 times a day how they felt and how interactions with parents were experienced. Preregistered dynamic structural equation models on 1439 (including 532 adjacent) parent-adolescent interactions revealed significant within-family associations: Adolescents experienced more positive affect during and following autonomy-supportive interactions, and vice versa. Adolescents felt more negative affect during and 3 h before psychologically controlling interactions. Between-family associations showed significant linkages between parenting and affect. These findings show that a moment of autonomy support can alter adolescents' everyday well-being.
