Evidence-based treatment for panic disorder consists of disorder-specific cognitive behavioural therapy (CBT) protocols. However, most measures of CBT competence are generic and there is a clear need for disorder-specific assessment measures.
To fill this gap, we evaluated the psychometric properties of the Cognitive Therapy Competence Scale (CTCP) for panic disorder.
CBT trainees (n = 60) submitted audio recordings of CBT for panic disorder that were scored on a generic competence measure, the Cognitive Therapy Scale - Revised (CTS-R), and the CTCP by markers with experience in CBT practice and evaluation. Trainees also provided pre- to post-treatment clinical outcomes on disorder-specific patient report measures for cases corresponding to their therapy recordings.
The CTCP exhibited strong internal consistency (α = .79-.91) and inter-rater reliability (ICC = .70-.88). The measure demonstrated convergent validity with the CTS-R (r = .40-.54), although investigation into competence classification indicated that the CTCP may be more sensitive at detecting competence for panic disorder-specific CBT skills. Notably, the CTCP demonstrated the first indication of a relationship between therapist competence and clinical outcome for panic disorder (r = .29-.35); no relationship was found for the CTS-R.
These findings provide initial support for the reliability and validity of the CTCP for assessing therapist competence in CBT for panic disorder and support the use of anxiety disorder-specific competence measures. Further investigation into the psychometric properties of the measure in other therapist cohorts and its relationship with clinical outcomes is recommended.
恐慌症的循证治疗包括特定于疾病的认知行为疗法（CBT）方案。然而，大多数 CBT 能力的衡量标准都是通用的，因此非常需要特定于疾病的评估措施。
为了填补这一空白，我们评估了针对恐慌症的认知疗法能力量表（CTCP）的心理测量特性。
CBT 学员（n=60）提交了针对恐慌症的 CBT 录音，这些录音由具有 CBT 实践和评估经验的标记物根据通用能力量表，即认知疗法量表修订版（CTS-R）和 CTCP 进行评分。学员还提供了与治疗录音相对应的案例的针对特定疾病的患者报告测量的治疗前至治疗后的临床结果。
CTCP 表现出很强的内部一致性（α=.79-.91）和评分者间可靠性（ICC=.70-.88）。该量表与 CTS-R 表现出了良好的聚合效度（r=.40-.54），尽管对能力分类的调查表明，CTCP 可能更能敏感地检测针对恐慌症的特定 CBT 技能的能力。值得注意的是，CTCP 首次显示出治疗师能力与恐慌症临床结果之间的关系（r=.29-.35）；而 CTS-R 则没有发现这种关系。
这些发现初步支持 CTCP 用于评估针对恐慌症的 CBT 治疗师能力的可靠性和有效性，并支持使用特定于焦虑症的能力衡量标准。建议进一步调查该测量方法在其他治疗师群体中的心理测量特性及其与临床结果的关系。
