ABSTRACT
To facilitate individual change is one of the major tasks of social work and other helping professions. Traditional treatment methods aimed at accom plishing this task have been described only in rather general, vague terms. Criteria for assessing whether desired changes have been accomplished have likewise been vague and poorly operationalized. When traditional treatment methods have been subjected to controlled experimental evaluation of out comes, the results have been disappointing. See, for example, Brown (1968); Meyer, Borgatta, and Jones (1965); Teuber and Powers (1953); also reviews by Briar (1966); Eysenck (1960a); Eysenck and Rachman (1965); Levitt (1957, 1963); Stuart (1969).
