The assertive training literature has documented the effectiveness of both behavioral and cognitive methods to increase individual's assertiveness. However, the ability for such methods to enhance the generalization of treatment effects to untrained assertive response classes and the natural environment has been poor. In addition, little notice has been paid to the durability of these changes. Although the past several years have witnessed more intensive efforts by investigators to program generalization as part of their interventions, results have continued to be disappointing. A specific generalization-enhancing treatment strategy, self-directed practice, has been utilized with much success in phobic populations. This strategy, and the theoretical orientation it reflects, has been proposed for use in assertive training. The present study sought to examine the effectiveness of this method as compared to the traditional assertive training procedures and investigate the role of self-efficacy expectations in mediating initial behavior change and its subsequent generalization.

This study examined psychoanalytic, physiological, and social learning models of depression in terms of etiology and symptomatology. Emphasis was placed on social learning theories of depression. First, Beck's cognitive approach stated that the root of depression was a negative cognitive set. Depressive episodes might be externally precipitated, but it was the individual's perception and appraisal of the event that rendered it depression inducing. Secondly, Seligman's learned helplessness model explained reactive depression in terms of a belief in one's own helplessness. Specifically, Seligman stated belief in the uncontrollability of outcomes resulted in depression, irrespective of the correspondence of such beliefs to objective circumstances. Additionally, depression resulted from noncontingent aversive stimulation and noncontingent positive reinforcement. Thirdly, Lewinsohn's model was based on these assumptions: a low rate of response-contingent positive reinforcement which acted as an eliciting stimulus for depressive behaviors. This low rate of response-contingent positive reinforcement constituted an explanation for the low rate of behaviors observed in the depressive. Total amount of response—contingent positive reinforcement is a function of a number of events reinforcing for the individual, availability of reinforcement in the environment, and social skills of the individual that are necessary to elicit reinforcement.

The present study translated the major theories of obesity into physiological terms, then tested for the ways these theories might find physiological expression. Theoretical positions included the psychoanalytic perspective, emphasizing intrapsychic processes; psychosomatic perspective, emphasizing food as an anxiolytic agent; and Schachterian perspective, emphasizing heightened sensitivity to external stimuli. Additionally, two classificatory distinctions, age at onset of obesity and extent of dietary restraint, were examined. The later distinction suggested that Schachterian findings on obese behavior were due not to obesity, but to a dieting life style.
