The Mediating Role of Therapeutic Alliance in the Relation Between Self-critical Perfectionism and Subsequent Changes in Body Dissatisfaction and Drive for Thinness. Note: Coefficients reported between brackets represent the direct relation between SC perfectionism T1 and the outcome without therapeutic alliance T2 in the model. SC = Self-critical. *p < .05.
