Abstract

Objective: This study evaluated the psychometric properties of the Person-Centered and Experiential Psychotherapy Scale for Emotion-Focused Therapy: Adherence and Competence Observer Rating (PCEPS-EFT-9). It includes its reliability, discriminant validity between emotion-focused therapy (EFT) and person-centered therapy (PCT), and its predictive validity for therapeutic outcomes.

Method: Data were drawn from a pilot study comparing EFT and PCT in treating social anxiety. Recordings of 22 EFT and 14 PCT sessions from early and mid-therapy phases were coded using the PCEPS-EFT-9. Discriminant validity was assessed by comparing scores between therapies and predictive validity through correlations with residual symptom changes.

Results: The PCEPS-EFT-9 showed strong inter-rater reliability (intraclass correlation coefficients = .90-.93). Internal consistency was high for EFT (Cronbach's alpha > .97) and moderate for PCT (Cronbach's alpha = .65). EFT therapists scored significantly higher than PCT therapists (p < .001), supporting discriminant validity.

Conclusion: The PCEPS-EFT-9 demonstrated robust reliability and validity, supporting its use in evaluating therapist adherence and competence in EFT. Higher adherence and competence were linked to improved outcomes, highlighting the importance of monitoring treatment fidelity in psychotherapy research.

以人为本的体验性心理治疗量表中以情绪为中心的治疗版本的心理测量学评价：治疗师依从性和能力的测量。

目的：评价以人为中心的体验式心理治疗情绪性治疗依从性和能力观察者评定量表（ppep - eft -9）的心理测量学特征。它包括信度、情绪聚焦治疗（EFT）和以人为中心治疗（PCT）的区别效度以及对治疗结果的预测效度。方法：数据来自一项比较EFT和PCT治疗社交焦虑的初步研究。使用ppep -EFT-9对治疗早期和中期的22次EFT和14次PCT记录进行编码。判别效度是通过比较治疗和预测效度之间的得分来评估的，通过与剩余症状变化的相关性来评估。结果：peps - eft -9具有较强的组间信度（组内相关系数= 0.90 ~ 0.93）。EFT的内部一致性高（Cronbach’s alpha = 0.97）， PCT的内部一致性中等（Cronbach’s alpha = 0.65）。EFT治疗师的得分明显高于PCT治疗师(p)结论：ppep -EFT-9具有强大的信度和效度，支持其用于评估治疗师在EFT中的依从性和能力。更高的依从性和能力与改善的结果有关，强调了在心理治疗研究中监测治疗忠实度的重要性。
