The Role of Parental Reflective Functioning in Associations between Daily Autonomy-Relevant Parenting, Parenting Stress, and Early and Middle Adolescents' Day-to-Day Difficulties.

Autonomy-supportive parenting benefits adolescents' psychosocial adjustment, but daily fluctuations in adolescent difficulties and parenting stress can reduce autonomy support and lead to more controlling practices. However, currently it is not yet well understood why some parents seem better able to deal with the daily upheavals characteristic of adolescence, while other parents may resort to controlling practices. To address this gap, the present studies examined the moderating role of parental reflective functioning (i.e., parents' capacity to understand their adolescent's behavior in terms of mental states) in the daily relationships between adolescent difficulties, parental stress, and autonomy-supportive or controlling parenting. Two 7-day diary studies were conducted, of which Study 1 involved 220 parents of early adolescents (M_age = 13.05 years, SD = 0.87, range 10-15, 66% female) and Study 2 involved 161 parents of middle adolescents (M_age = 15.56 years, SD = 1.14, range = 13-18, 61.5% female). Multilevel analyses indicated that daily perceived externalizing difficulties and parental stress were associated with less autonomy-supportive and more controlling parenting. Furthermore, prementalizing (i.e., attributing malevolent intentions to adolescents) predicted less autonomy support and more controlling parenting. Greater interest and curiosity about adolescents' mental states buffered the associations between middle adolescents' (internalizing and externalizing) difficulties and parent-reported controlling parenting. These findings highlight the role of both parent and adolescent characteristics in day-to-day parenting fluctuations and underscore the importance of parental reflective functioning in understanding variations in autonomy-supportive and controlling practices.
