In this chapter we focus on research published since our previous reviews (Greenberg, Elliott & Lietaer, 1994; Elliott, Greenberg & Lietaer, 2004), which covered research published between 1978 and 2001, plus additional earlier research on humanistic-experiential psychotherapy (HEP) outcome that we have been able to track down. A key element of the chapter is a meta-analysis of nearly 200 HEP outcome studies (through 2008) and a survey of the use of the approach with different client groups. In addition, we offer a meta-synthesis of qualitative research on these therapies (cf. Timulak, 2007), and provide a narrative review of recent quantitative research on change processes in HEPs. We conclude by reviewing and integrating the literature reviewed and discuss policy implications.
