The necessary and sufficient conditions of therapeutic personality change.

For many years I have been engaged in psy-chotherapy with individuals in distress. In recentyears I have found myself increasingly concernedwith the process of abstracting from that experi-ence the general principles which appear to beinvolved in it. I have endeavored to discover anyorderliness, any unity which seems to inhere inthe subtle, complex tissue of interpersonal rela-tionship in which I have so constantly been im-mersed in therapeutic work. One of the currentproducts of this concern is an attempt to state, informal terms, a theory of psychotherapy, of per-sonality, and of interpersonal relationships whichwill encompass and contain the phenomena ofmy experience.
