There is a widely acknowledged lack of clarity in psychotherapeutic training about the role of personal therapy in developing practitioner competence. This paper presents part of a wider ongoing qualitative study exploring the role that personal therapy plays in the clinical practice and training of experienced counselling psychologists. Results derived from an interpretative phenomenological analysis suggest that personal therapy is valued mainly as a means of enhancing reflectiveness within clinical work. Detailed examination of a subset of the data offers scope for exploring how this process may occur within therapy, and points to the potential significance of early attachment experiences in the development and amplification of participants' reflective capacities. A possible theoretical framework is proposed and implications for future research discussed. (Contains 1 table.)
