This study examined how sex of client and sex and experience level of the counselor affected behaviors in counseling. Twelve male and 12 female counselors, half inexperienced and half experienced, each recorded the second counseling session with one male and one female client. Satisfaction items, frequency counts of counselor and client verbal behavior, activity levels, and judges' ratings were obtained for each session. Results indicated that same-sex pairings had more discussion of feelings by both counselor and client and that inexperienced males and experienced female counselors were more active and empathic and elicited more feelings from clients than did their counterparts. Thus, counselors responded differently to different clients.Many counselors consider it appropriate to match sex of client and counselor.

Male and female clients do present different problems in counseling (Chesler, 1971;Gurin, Veroff, & Felds, 1960;Howard, Orlinsky, & Hill, 1970) and are viewed differently by counselors (Broverman, Broverman, Clarkson, Rosenkrantz, & Vogel, 1970), but little research has focused on the specific behavioral effects of sex of client and sex and experience level of counselors.Sex pairings may affect the counseling process. Howard et al. (1970) discovered that, following therapy, female clients were more satisfied with female therapists. Chesler (1971) hypothesized that all-male pairings would encourage aggression and competition, whereas male therapist -female client pairings would involve the greatest
