Objective Both Internet-delivered cognitive behavioural therapy (ICBT) and Internet-delivered psychodynamic psychotherapy (IPDT) have shown promise in the treatment of social anxiety disorder (SAD). However, little is known about client preferences and what predicts treatment outcome. The objective of the present pilot study was to examine preference for ICBT versus IPDT in the treatment of SAD and whether participants' preference strength and therapeutic alliance predicted treatment response. Further, we also investigated the effect of the two treatments, including 6-months follow-up. Method Thirty-six participants were instructed to choose between either IPDT or ICBT based on a brief description. Both treatments were 10 weeks long. Liebowitz Social Anxiety Scale – Self Report was used as the primary outcome measure. Results IPDT (N = 23; 63.9%) was preferred more often than ICBT (N = 13; 36.1%), but the difference did not reach statistical significance (p = .10). Preference strength did not predict the treatment effect but therapeutic alliance did. The observed within-group effects for the treatment period were d = 0.40 [−0.21, 0.99] for the IPDT group and d = 0.53 [−0.29, 1.31] for the ICBT group. An intention-to-treat (ITT) analysis revealed no significant difference between the two treatments on any outcome measure at either post-treatment or at six months follow-up. Conclusion The present pilot study did not find a difference in preference for IPDT or ICBT in the treatment of SAD and both treatments resulted in small to moderate improvements in symptoms of SAD. Preference strength might not predict treatment effect, but this needs to be tested in larger studies.

基于互联网的心理动力学疗法与社交焦虑症的认知行为疗法：偏好研究

目的 互联网提供的认知行为疗法（ICBT）和互联网提供的心理动力学心理疗法（IPDT）在社交焦虑障碍（SAD）的治疗中显示出前景。然而，关于客户偏好和预测治疗结果的因素知之甚少。本试点研究的目的是检查 ICBT 与 IPDT 在治疗 SAD 中的偏好，以及参与者的偏好强度和治疗联盟是否预测治疗反应。此外，我们还调查了两种治疗的效果，包括 6 个月的随访。方法 指示 36 名参与者根据简要描述在 IPDT 或 ICBT 之间进行选择。两种治疗均为 10 周。Liebowitz 社交焦虑量表 - 自我报告被用作主要结果测量。结果 IPDT（N = 23；63。9%) 比 ICBT (N = 13; 36.1%) 更受欢迎，但差异没有达到统计学意义 (p = .10)。偏好强度不能预测治疗效果，但治疗联盟可以。在治疗期间观察到的组内效应对于 IPDT 组为 d = 0.40 [-0.21, 0.99]，对于 ICBT 组为 d = 0.53 [-0.29, 1.31]。意向治疗 (ITT) 分析显示，在治疗后或六个月的随访中，两种治疗在任何结果指标上均无显着差异。结论 目前的试点研究没有发现在治疗 SAD 中对 IPDT 或 ICBT 的偏好存在差异，并且两种治疗都导致 SAD 症状有小到中度的改善。偏好强度可能无法预测治疗效果，但这需要在更大规模的研究中进行测试。
