Presession mood induction in therapists: Effects on therapist empathy.

Previous studies show that therapist mood is associated with psychotherapy processes, but the observational nature of these studies does not allow for causal inference. It is also unclear if other therapist characteristics, such as therapist trait empathy, moderate the relation between therapist mood and process variables. Thirty-four therapists and volunteer client dyads participated in three weekly counseling sessions. Before each session, therapists were induced to experience one of three moods, elation, depression, or neutral, in a counterbalanced order, using a combination of music and the Velten method. After each session, clients rated therapist empathy and session quality, therapists rated session quality, and observers rated therapist empathy using videotapes. Electrocardiogram was collected from therapists and clients during the session to assess heart rate synchrony as an indicator of therapist empathy. Therapist trait empathy moderated the effect of mood induction on observer-rated therapist empathy, such that when induced to experience elation, therapists with high trait empathy were observed to be more empathic, whereas therapists with low trait empathy were observed to be less empathic. Therapists of different trait empathy levels did not differ on observer-rated empathy when induced to experience depression or neutral mood. No significant effect of mood induction was found for client-rated empathy, client- and therapist-rated session quality, or heart rate synchrony. The experimental design offers preliminary evidence that therapist presession mood may influence the psychotherapy process. The findings are explained in light of empathy amplification and empathy attenuation hypotheses in relation to positive emotion. Practice and research implications are discussed.
