Good can be stronger than bad: the daily relationship among maternal warmth, mother-teen conflict and adolescents' self-esteem.

Self-esteem is associated with adaptive adolescent outcomes but tends to decline in adolescence. Parent-teen warmth has been linked to concurrent increases in adolescents' self-esteem while adolescents' conflict with parents is detrimental to their self-esteem in cross-sectional or longitudinal studies. However, it is unknown how adolescents experience of maternal warmth and conflict with mothers are correlated with their daily self-esteem, and whether these associations vary in adolescents' gender, age and family subjective socioeconomic status (SES) from the perspective of Process-Person-Context-Time (PPCT) theory. To address this gap, 293 adolescents (  = 13.88 years,  = .62) were recruited from a school, reporting their daily experience of maternal warmth, conflict with mothers and self-esteem by answering checklists for up to 7 days. Multilevel analysis showed that adolescents reported significantly higher self-esteem on days they experienced more warmth or less conflict with mothers than usual. Moreover, maternal warmth was linked to next-day self-esteem positively, yet mother-teen conflict not shown this spill-over effect. Gender, age and subjective SES did not moderate all the daily associations among mother-teen warmth, conflict and self-esteem. Findings suggest that mother-teen interactions play both protective and detrimental role in adolescents' daily self-image and that "good" interaction goes a longer way than "bad" one.
