Guided internet-delivered CBT for anxiety disorders has received increasing empirical support, but little is known regarding the role of the therapist.
This study addressed therapist factors in guided internet-delivered cognitive behavioural therapy for anxiety disorders.
Data from three controlled trials with a total N of 119 were analyzed with attention to differences between eight therapists.
No significant mean level differences between therapists appeared in the dataset. However, one significant intraclass correlation between participants was found, suggesting that the outcome on the Beck Anxiety Inventory might have been influenced by the impact of the individual therapists.
The therapist can possibly have some influence on the outcome of guided internet-delivered CBT for anxiety disorders, but studies with more statistical power are needed to establish whether therapist effects are present in this modality of psychological treatment. The present study was underpowered to detect minor therapist effects.
基于网络的认知行为疗法（CBT）已在焦虑障碍的治疗中得到越来越多的实证支持，但关于治疗师的作用却知之甚少。
本研究旨在探讨焦虑障碍网络 CBT 中治疗师的因素。
对三项包含共 119 名参与者的对照试验的数据进行了分析，关注了 8 位治疗师之间的差异。
在数据集中未发现治疗师之间存在显著的平均水平差异。然而，发现了参与者之间的一个显著的组内相关，表明贝克焦虑量表的结果可能受到个别治疗师影响。
治疗师可能对焦虑障碍的网络 CBT 结果产生一定影响，但需要更多的统计效能研究来确定这种心理治疗模式是否存在治疗师效应。本研究的统计效能不足，无法检测到较小的治疗师效应。
