When causal inferences are to be synthesized across multiple studies, efforts to establish the magnitude of a causal effect should be balanced by an effort to evaluate the generalizability of the effect. The evaluation of generalizability depends on two factors that are given little attention in current syntheses: construct validity and external…

D'Eon et al. concluded that change in performance self-assessment means from before to after a workshop can detect workshop success in their and other situations. In this commentary, their recommendation is refuted by showing that (a) self-assessments with balanced over- and underestimations are still biased and should not be used to evaluate…

Contends that success of supported employment service programs depends on the ability of new programs to replicate results of supported work demonstration projects. Notes that the capacity to verify accurate replication independently is limited, as is knowledge of the extent to which supported employment demonstration programs generalize to a wide…

Responds to article by DuPaul and Eckert on generalization and maintenance of behavior change resulting from packaged social skills training programs. Argues that DuPaul and Eckert focused their attention on generalization and ignored more immediate issue--that participation in these programs failed to produce meaningful change in social behavior.…

Responds to article by DuPaul and Eckert on generalization and maintenance of behavior change resulting from packaged social skills training programs. Agrees with DuPaul and Eckert and focuses commentary on identification and discussion of issues raised by suggestions to reprogram school environments to promote and change social behavior. (NB)

Responds to article by DuPaul and Eckert on generalization and maintenance of behavior change resulting from packaged social skills training programs. Discusses failure to obtain generalization from two perspectives: topographical generalization and functional generalization. Suggests that generalization programming based on functional analysis…

Reflects on a study of the effectiveness of an inservice training program on individualized education programs that was provided to two vocational coordinators and seven teachers of students with mental retardation. Discusses the reasons the study focused on behavioral objectives and the importance of writing quality behavioral objectives. (CR)
