Effects of covert modeling and coding of modeled stimuli on assertive behavior.

The present investigation examined the effects of covert modeling in developing assertive behavior and the effects of verbal coding of the modeling stimuli on treatment outcome. In a 2 × 2 design, modeling (imagining an assertive model versus imagining scenes without an assertive model) and summary coding (developing verbal codes of the modeled material versus not developing codes) were combined. The results indicated that modeling and coding enhanced behavior change across self-report inventories and a behavioral role-playing test. Superior performance on these measures was achieved by the modeling group that both imagined an assertive model and engaged in summary coding. These effects transferred to novel role-playing situations at post-treatment and were maintained at a 6-month follow-up assessment. The results suggest that coding of treatment stimuli affects acquisition and maintenance of the modeled behaviors in treatment in a way that resembles findings from laboratory research on modeling.
