Effects of live modeling, covert modeling and rehearsal on assertiveness in psychiatric patients.

The present study evaluated the effects of live modeling, covert modeling, and rehearsal in unassertive psychiatric patients. Psychiatric patients scoring 19 or below on the Wolpe-Lazarus Assertiveness Scale were assigned to one of five conditions, with 10 subjects in each group: (1) Test-retest (no treatment). (2) Live modeling plus rehearsal. (3) Live modeling without rehearsal. (4) Covert modeling plus rehearsal, and (5) Covert modeling without rehearsal. All subjects were videotaped (pre- and post-test) while responding to eight interpersonal situations (four training scenes; four generalization scenes) requiring assertive responses. Pre- and post-test responses for all subjects were rated independently by judges on several verbal and non-verbal components of assertiveness. The results indicated that live modeling and covert modeling effected improvements in the assertive behavior of the patients, but that the two treatments were not differentially effective. Generally, the addition of rehearsal to live or covert modeling failed to enhance treatment. But on two measures, the covert modeling plus rehearsal condition was superior to the other treatments. There was evidence for transfer of treatment effects from training to generalization scenes. No differences were found among the groups on the Wolpe-Lazarus Assertiveness Scale and the Eysenck Personality Questionnaire. The results were discussed in light of prior findings with live and covert modeling procedures.
