Identifies promising developments and mistakes found in assertiveness training programs. Discusses problems arising from negative image, generalizability of learned skills and, especially, curriculum format. Concludes that elicited "assertiveness" may not have positive outcomes for all individuals. Recommends enhancement interventions…

The cross-levels hypothesis is presented as an explanation for program evaluation failures. It states that the usefulness of evaluation data as feedback for decision making varies inversely with the number of organizational levels between the action the data describe, and the decisions they are intended to influence. To be useful for decision…

This paper presents a model for school psychologists to instruct parents in behavior modification procedures for use with their children. This model, designed for use by individuals who have a basic working knowledge of operant conditioning and applied behavior analysis procedures, consists of three training sessions which are outlined with…
