One hundred one counselors/therapists from 13 agencies completed a 16-item questionnaire describing their reactions to behaviors of three clients that a previous study had shown were irritating or annoying to therapists. The subjects' reactions to certain "rules" of therapy and their ambiguity tolerance were also examined. Counselors' reactions were most negative to client impositions and attacks and least negative to client resistance and involvement in client dynamics. Several rules were significantly correlated with counselors' annoyance, but there was no relationship with counselors' ambiguity tolerance.Therapists' annoyance or anger with clients has largely been ignored in the research literature, but a number of authors have discussed their clinical observations of therapists' anger and its impact on clients. Cahill (1981), Rothenberg (1971), and Rubin (1969 all stressed anger as a positive, caring drive. Cahill (1981) made an important distinction wherein anger occurs in the context of a relationship in which the object of the anger is trusted and pursued. In contrast, he suggested that hostility originates in disappointment, rejection, and punitiveness.Anger, however, has its more noxious aspects, often arising in situations in which the individual feels less powerful, useful, whole, or valued (e.g., Gaylord, 1984;Rothenberg, 1971). Novaco (1976) implicated anxiety in the arousal of anger, suggesting that anger functions as an ego defense, a protective reaction to feelings of vulnerability.For therapists there is also the danger that annoyance/anger at clients' behavior might be a manifestation of countertransference and, as such, might be a reflection of the therapist's own unresolved neuroses. Discussing negative countertransference, Singer (1965) commented that "it is important to distinguish between realistic negative attitudes such as annoy-SUZANNE R.
