This paper reviews the research literature on personal therapy and mak
es some recommendations for how future work in this area may be improv
ed. Despite the general acceptance of the importance of personal thera
py amongst therapists, there has been relatively little research to ev
aluate its effectiveness. The vast majority of studies have consisted
of surveys of therapists' opinions and experiences of therapy or natur
alistic comparisons across therapists who have or have not had therapy
. The interpretation of most findings is compromised because of small
sample sizes and confounding variables, nevertheless some conclusions
can be made. Whilst the majority of therapists feel chat they have ben
efited professionally from personal therapy there is very little empir
ical evidence that it has any measurable effect on client outcome. How
ever, there is some evidence that personal therapy has a positive effe
ct on those therapist qualities often cited as constructive to client
change (e.g. empathy, warmth, genuineness). What is evident is that th
ere is a need for more methodologically sound research as well as a mo
re theoretical understanding of how personal therapy affects clinical
practice, before any firm conclusions can be drawn about its usefulnes
s. It is suggested that it may be more useful for future research in t
his area to focus on therapy process rather than client outcome.
