The process of change in brief psychotherapy: Effects of psychodynamic and cognitive-behavioral prototypes.

A brief psychodynamic psychotherapy was assessed using the Brazilian Portuguese version of the Psychotherapy Process Q-Set (PQS). Each session was scored for its adherence to expert psychodynamic therapy (PDT) and cognitive-behavioral therapy (CBT) prototypes derived from the PQS. Results revealed that the therapy process adhered more closely to prototypical CBT than prototypical PDT. Bivariate time-series analyses showed that prototype components capturing the client's adherence to ideal CBT behaviors and collaboration between therapist and client on ideal PDT and CBT behaviors predicted therapy progress. In addition, specific client symptoms influenced whether the therapist adhered to prototypical PDT or CBT behaviors. [ABSTRACT FROM AUTHOR]
