ABSTRACT
Drawing from a larger theoretical context, six conditions are postulated as necessary and sufficient conditions for the initiation of a process of constructive personality change. A brief explanation is given of each condition, and suggestions are made as to how each may be operationally defined for research purposes. The implications of this theory for research for psychotherapy, and for educational and training programmes aimed at constructive personality change, are indicated. It is pointed out that many of the conditions which are commonly regarded as necessary to psychotherapy are, in terms of this theory, nonessential.
