Therapist drift refers to the tendency for psychologists to move away from the delivery of the evidence-based practices in which they are trained, even when resourced to implement them. When therapists do not provide, or only partially provide, empirically supported treatments their patients may receive interventions that are not effective, or that are harmful. The aim of the current study was to conduct a systematic review of the literature to ascertain the correlates of therapist drift in psychological practice, focusing on therapist characteristics. Relevant articles were identified through a comprehensive search of the literature. Sixty-six studies met the inclusion criteria and nine therapist characteristics that correlate with therapist drift were identified. These characteristics included: (1) therapist knowledge; (2) attitudes toward research; (3) therapist anxiety; (4) clinical experience; (5) therapist age; (6) theoretical orientation; (7) critical thinking; (8) personality traits; and (9) cultural competency. The interrelationships between these factors are explored and the clinical implications of results are discussed. Recommendations are made for future research.

治疗师漂移是指心理学家倾向于远离提供他们接受培训的循证实践，即使有资源实施它们。当治疗师不提供或仅部分提供经验支持的治疗时，他们的患者可能会接受无效或有害的干预措施。当前研究的目的是进行系统回顾文献以确定心理实践中治疗师漂移的相关性，重点关注治疗师特征。通过对文献的全面检索，确定了相关文章。六十六项研究符合纳入标准，并确定了九项与治疗师漂移相关的治疗师特征。这些特征包括：（1）治疗师知识；(2) 对研究的态度；(3) 治疗师焦虑；（四）临床经验；(5) 治疗师年龄；（六）理论导向；(7) 批判性思维；（八）人格特质；(9) 文化能力。探讨了这些因素之间的相互关系，并讨论了结果的临床意义。对未来的研究提出了建议。
