Do clients train therapists to become eclectic and use the common factors? A qualitative study listening to experienced psychotherapists

BACKGROUND: Psychotherapists must choose from an overwhelming number of theoretical models and empirically supported treatments to guide their work. Meta-analytic studies show there is comparable efficacy among the choices, making the decision about which approach to use difficult. Research indicates there are pantheoretical elements found in all effective models, called the common factors, which can offer psychotherapists a focusing point to maximize their effectiveness regardless of their chosen approach. Most psychotherapists begin practicing from a traditional theoretical orientation, but then their approach evolves over time toward an unintentional eclecticism, derived primarily from their practice experience with clients. METHODS: This exploratory qualitative study conducted in-depth interviews with six experienced clinical social workers about their evolution as psychotherapists and what they believe creates change in psychotherapy. The interviews were conducted using standardized prompts and then coded and analyzed utilizing thematic analysis based on a six-phase framework. RESULTS: The analysis suggests the psychotherapists had evolved to conducting therapy via an implicit and unique approach based on an unintentional heavy use of common factors. Five prominent themes emerged as central components of change in psychotherapy: the therapeutic relationship as a primary change agent, the importance of the therapist genuineness, the need to acknowledge and act upon a poor therapist—client match, the client bearing the primary responsibility for change, and the therapists’ development of unintended eclecticism in response to client interactions. CONCLUSIONS: In practice, most psychotherapists start practicing from a traditional theoretical orientation only to find their approach evolves over time toward an informal eclecticism featuring common factors. This common factors-based eclecticism emerges primarily from practice experience with clients. These findings suggest an avenue for further inquiry—if psychotherapists are going to gradually evolve in an unplanned eclectic direction guided by their client interactions, are they also concurrently and inherently drawn to the common factors? If the answer proves to be yes, what are the implications for early training? Should the gradual emphasis toward common factors be supplanted with a more intentional and efficient focus on them in the training of students and early career clinicians?
