This study investigates how social workers, psychologists, and psychiatrists document the treatment they provide clients to managed behavioral health care organizations. The rosters of the Register of Clinical Social Workers, the American Psychological Association, and the American Psychiatric Association yielded a sample of 168 private practicing social workers, 158 psychologists, and 258 psychiatrists from across the nation. Results indicated that practitioners differed based on age, amount of time spent in private practice, racial self-identification, percentage of time with clients diminished due to communicating with managed behavioral health care organizations, and documentation of clients' prognoses. Some practitioners believe it is necessary to report treatment needs in ways to assure certification rather than in ways that accurately depict clients' clinical profiles. The ramifications for clinicians' evaluation of their own practices, reimbursement for their services, and meeting clients' needs while working under managed behavioral health care guidelines are discussed.
