The American Group Psychotherapy Association began in 1942 as an elite, strictly Freudian organization. Its dramatic growth in the 1960s and 1970s was accompanied by much theoretical disagreement and professional "chauvinism." During the past decade, however, the ideological controversy has yielded to pluralism in theory and eclecticism in practice.
