Although receiving autonomy support within close friendships has been found to relate to higher levels of psychosocial well-being, less is known about why some friends are more autonomy supportive or controlling than others. The present study investigated the role of individuals' evaluative concerns perfectionism and experienced need satisfaction or frustration within the friendship as predictors of provided autonomy support and psychological control towards their best same-sex friend. Participants were 108 young adults (Mage = 23.18; SD = 2.26; 66.7% women) who reported on their level of evaluative concerns perfectionism, friendship need satisfaction and frustration, and provided friendship autonomy support and psychological control. Results showed that evaluative concerns perfectionism related positively to provided psychological control and negatively to provided autonomy support via, respectively, higher need frustration and lower need satisfaction.
