Parent-adolescent interaction quality and adolescent affect-An experience sampling study on effect heterogeneity.

Person-environment interactions might ultimately drive longer term development. This experience sampling study (Data collection: 2019/20 the Netherlands) assessed short-term linkages between parent-adolescent interaction quality and affect during 2281 interactions of 124 adolescents (M age  = 15.80, SD age  = 1.69, 59% girls, 92% Dutch, Education: 25% low, 31% middle, 35% high, 9% other). Adolescents reported on parent-adolescent interaction quality (i.e., warmth and conflict) and momentary positive and negative affect five to six times a day, for 14 days. Preregistered dynamic structural equation models (DSEM) revealed within-family associations between parent-adolescent interaction quality and adolescent affect (concurrently: r = -.22 to .39; lagged effects: ß = -.17 to .15). These effects varied significantly between families. These findings stress the need for more person-specific research on parenting processes.
