Nature, extent, and importance of what psychotherapy trainees do not disclose to their supervisors.

Nondisclosures in supervision were studied for 108 supervisees. Supervisees reported an average of 8.06 nondisclosures ranging in importance level. Negative reactions to the supervisor were the most frequent type of nondisclosure. The most frequent reasons for nondisclosures were perceived unimportance, that the nondisclosure was too personal, negative feelings, and a poor alliance. The manner of nondisclosure was usually passive. Most nondisclosures were discussed with someone else, typically a peer. Supervisor style was related to content of and reasons for nondisclosure. Supervisees were less satisfied when they reported more negative reactions to supervisors and when they did not disclose because of poor alliances, supervisor incompetence, and fear of political suicide. Thus, nondisclosure affects the process of supervision. Further research is needed on how nondisclosures in supervision affect supervision and therapy processes.
