This study investigated the impact of counselor smoking behavior upon nonsmoking clients' perceptions of therapists both during and at the conclusion of treatment. Clients' impressions when counselor smoking behavior was consistent across sessions and when counselors smoked in only the first or only the second interview were examined. In addition, the effect of therapists' smoking behavior on the outcome of counseling was assessed in two ways: changes in clients' career decisiveness and counselors' ability to influence client behavior. Eighty-two female undergraduates met with a vocational counselor for two sessions during which the counselor either smoked or refrained from smoking. Prior to the first interview, subjects completed the Behavioral Indecision Scale. Subjects then met and discussed their vocational concerns with a counselor. Following the interview, subjects completed the Counselor Rating Form and the California Occupational Preference System. The latter instrument, an interest inventory, was interpreted by the counselor during the second interview. The Counselor Rating Form and the Behavioral Indecision Scale were again administered following the conclusion of treatment. Data were analyzed by 2 (counselors) X 2 (conditions) X 2 (interviews) multivariate analyses with repeated measures on the third factor. No significant differences emerged for clients' perceptions when the counselors' indulgence in or restraining from smoking was constant from the first to the second sessions. Similarly, clients' impressions did not differ in relation to the inconsistency of counselors' smoking behavior from the first to the second interviews. In addition, subjects' compliance to a counselor initiated behavioral task and reported certainty of career choice were not differentially affected by counselors' smoking behavior. In conclusion, this study suggests that it makes no difference in nonsmoking clients' impressions of therapists and in counseling outcome if the latter smoke during treatment. Suggested variables to further explore include the effects of counselors' smoking in brief and extended psychotherapy, the impact of therapists' smoking implements other than cigarettes, and smoking clients' perceptions of smoking therapists.
