Treatment preference and acceptability: Epistemology and locus of control

Treatment preference and acceptability were investigated in 397 female university students. Three audiovisual vignettes depicting a client and therapist discussing a body image disturbance problem were presented to subjects. Predictions were that subjects would prefer one of three therapy approaches-behavioral, cognitive-rational, or cognitive-constructivist-as a function of personal epistemology and locus of control. Overall, subjects rated the constructivist therapy approach more favorably than either the cognitive-rational or behavioral approach. Similarly, subjects evaluated the constructivist therapist more positively than either the rational or behavioral therapist. After degree of subject identification with the target problem was controlled, results indicated that matching subjects who had an external locus of control orientation to a behavioral or cognitive-rational therapist resulted in more favorable assessments of that therapist. Matching subjects who had an internal locus of control orientation to a constructivist therapist resulted in more positive assessments of that therapist. Implications for matching in clinical practice are discussed.
