“…The absence of symptom substitution in many reports was considered to refute psychodynamic conceptions of clinical disorders and their treatment (Jones, 1924;Mowrer & Mowrer, 1938;Yates, 1958a). Moreover, several studies indicated that treatment of a particular problem-such as obsessions, phobias, enuresis, and others-was often followed by improvements in other specific areas of functioning (e.g., Baker, 1969;Boersma, Den Hengst, Dekker, & Emmelkamp, 1976;Donner, 1970;Paul, 1967Paul, , 1968Solyom, Heseltine, McClure, Ledwidge, & Kenny, 1971). These beneficial effects were frequently considered as evidence for "generalization," although the mechanisms responsible for broad changes have not been examined or clarified by the findings themselves.…”
