To investigate if therapists' personality influences their patients' treatment outcomes. = 4,052 patients were treated by 69 therapists, including 36 Psychological Wellbeing Practitioners (PWPs) and 33 Cognitive Behavioural Therapists (CBTs). Therapists completed the NEO-PI-R personality inventory, they reported years of clinical experience, and expert assessors rated their clinical competence and reflective abilities. Their patients completed pre and post-treatment measures of depression (PHQ-9) and anxiety (GAD-7). Associations between therapist personality traits and patient treatment outcomes were examined using multilevel modelling, controlling for therapist demographics, clinical experience, technical competence and reflective ability. Relative to other sources of variability, therapists accounted for 1% to 3% of overall variability in treatment outcomes. However, the magnitude of systematic heterogeneity in performance was around 6%, such that the best-performing therapists outperformed average therapists by a margin of moderate to large effects ( = .57-1.10). Clinical experience, technical competence and reflective ability were unrelated to treatment outcomes. Patients treated by PWPs with above-average scores and CBTs with above-average scores had poorer treatment outcomes. Therapist effects may be partly explained by the influence of their personality on their work with anxious and depressed patients.
研究治疗师的个性是否会影响患者的治疗效果。共有 4052 名患者接受了 69 名治疗师的治疗，其中包括 36 名心理健康从业者（PWPs）和 33 名认知行为治疗师（CBTs）。治疗师完成了 NEO-PI-R 人格量表，他们报告了多年的临床经验，专家评估者评估了他们的临床能力和反思能力。他们的患者在治疗前和治疗后完成了抑郁（PHQ-9）和焦虑（GAD-7）的测量。使用多层次模型，控制治疗师的人口统计学、临床经验、技术能力和反思能力，研究了治疗师人格特质与患者治疗结果之间的关联。与其他变异源相比，治疗师在治疗结果的整体变异中占 1%至 3%。然而，绩效的系统异质性的幅度约为 6%，因此表现最好的治疗师比平均治疗师的表现要好中等至较大的效应（ = .57-1.10）。临床经验、技术能力和反思能力与治疗结果无关。接受高于平均得分的 PWPs 和高于平均得分的 CBTs 治疗的患者治疗效果较差。治疗师的影响可能部分归因于他们的个性对他们与焦虑和抑郁患者工作的影响。
