Is professional training worth the bother? A review of the impact of psychotherapy training on client outcome

This article reviews the research literature on the effectiveness of paraprofessional counsellors and the impact of psychotherapy training on client outcome. Methodological and conceptual difficulties that have hampered previous research in this area are noted, and several well-designed individual studies are highlighted. The existing evidence supports the efficacy of paraprofessional counsellors, although professional training may lead to better outcome in specific areas, such as greater client retention, briefer therapy, and better overall wellbeing for clients. However, methodological limitations of the research prohibit definitive conclusions. Guidelines for future research are offered.
