While psychotherapies are of established value, they may, as active treatments, risk adverse outcomes. As there is no validated measure of potentially negative psychotherapeutic ingredients, we sought to develop such a measure for use in psychotherapy evaluation studies. Based on a review of the literature, a 103-item experiential measure was derived. Psychometric properties and scale score correlates were examined in a sample of more than 700 respondents. Principal component analyses revealed a five-factor solution, explaining 53.4% of the variance; namely 'Negative Therapist', 'Pre-occupying Therapy', 'Beneficial Therapy', 'Idealization of Therapist' and 'Passive Therapist' constructs. Derived factors had high internal consistency, and scale scores were correlated with a number of clinically relevant demographic and treatment characteristics. An independent study established high test-retest reliability for the measure. Assessment of any adverse effects of psychotherapy is of clinical and research significance. We report the development of a measure that should allow the impact of such effects to be quantified in treatment studies, and especially in apportioning the contribution of such non-specific therapeutic effects.
虽然心理治疗具有既定的价值，但作为一种积极的治疗方法，它们可能存在不良后果的风险。由于目前还没有经过验证的测量潜在负面心理治疗成分的方法，我们试图开发这样一种方法，用于心理治疗评估研究。基于文献回顾，我们得出了一个包含 103 个项目的体验式测量方法。在超过 700 名受访者的样本中，我们对其心理测量学特性和量表评分相关性进行了检验。主成分分析显示，该方法具有五个因素解决方案，可解释 53.4%的方差，分别为“消极治疗师”、“占据治疗”、“有益治疗”、“理想化治疗师”和“消极治疗师”。衍生因素具有较高的内部一致性，量表评分与许多临床相关的人口统计学和治疗特征相关。一项独立的研究确立了该测量方法的高重测信度。评估心理治疗的任何不良影响都具有临床和研究意义。我们报告了一种方法的开发，该方法应允许在治疗研究中量化这些影响，特别是在分配这种非特异性治疗效果的贡献方面。
