Results indicated that clients, expectations for personal commitment and perception of counselors5 credibility of expertness and attractiveness predicted the task and goal dimensions of the working alliance. Clients’ expectations for personal commitment and facilita-tive conditions and perception of counselors’ credibility of expertness，attractiveness and trustworthiness predicted the bond dimension of the working alliance. Also, clients5 expectations of counseling predicted working alliance indirectly through perceived counselor credibility, the effect size is .42 (p < .05), and clients, expectations of counseling directly predicted working alliance, the effect size is .23 (p < .05).
