Although research increasingly addresses the role of parenting in fostering adolescent disclosure, most research relied on self-report measures of parenting and did not address the role of autonomy support. In the present observational study (conducted in Belgium), with 62 mother-adolescent dyads (mean age mothers = 44 years; mean age adolescents = 14 years; 77% of adolescents female), we rated mothers' provision of autonomy support during a 10-minute conversation about friendships. We found that observed maternal autonomy support was related positively to adolescents' degree of and volitional reasons for disclosure about friends. These associations were mediated by observed non-verbal reciprocity during the conversation and by adolescent satisfaction of their needs for autonomy and relatedness. Mothers' autonomy-support and mother-adolescent reciprocity also predicted mothers' own psychological need satisfaction and conversation pleasure. The relevance of the findings for adolescent autonomy and disclosure are discussed.
