Background:Person-based cognitive therapy (PBCT) was developed as a treatment for psychosis. The effectiveness of group PBCT was examined in the Mindfulness for Voices (M4V) randomized controlled trial and generated promising results. Group PBCT was implemented as a trans-diagnostic treatment for distressing voices within the Sussex Voices Clinic (SVC), a specialist secondary care mental health service.Aim:To conduct a service evaluation of engagement, outcomes and cost of group PBCT within SVC, and to compare engagement and outcomes from routine practice with the M4V trial. Secondary aims were to explore predictors of levels of engagement and change in group PBCT.Method:Service level data from 95 SVC patients were evaluated. Descriptive statistics, hypothesis tests and linear regression models were used. The primary clinical outcome was voice-related distress. Engagement levels and pre–post effect sizes were estimated; associated predictors were explored.Results:Fifty-nine per cent of patients completed group PBCT within SVC, compared with 72% within M4V. Completers within SVC had lower baseline depression scores compared with non-completers. There were significant improvements in voice-related distress (Cohen’s d = –0.47; p = 0.001), subjective recovery (Cohen’s d = 0.35; p = 0.001) and depression (Cohen’s d = –0.20; p = 0.044); these outcomes were comparable to M4V. Higher baseline subjective recovery and lower depression both predicted improvement in voice-related distress. Therapy within SVC cost an average of £214 per patient.Conclusion:PBCT groups can be delivered trans-diagnostically in routine clinical practice. Engagement was lower when compared with an RCT, but outcomes were comparable. The low level of resources involved suggests that group PBCT can offer value for money.

针对令人痛苦的声音的基于团体正念干预的服务评估：随机对照试验的结果与常规临床实践相比如何？

背景：以人为本的认知疗法（PBCT）是作为一种治疗精神病的方法而开发的。Mindfulness for Voices (M4V) 随机对照试验检验了 PBCT 组的有效性，并产生了可喜的结果。小组 PBCT 被实施为苏塞克斯之声诊所 (SVC) 内令人痛苦的声音的跨诊断治疗，这是一个专业的二级保健心理健康服务。目的：对 SVC 内的小组 PBCT 的参与、结果和成本进行服务评估，以及将常规实践的参与度和结果与 M4V 试验进行比较。次要目的是探索参与水平和组 PBCT 变化的预测因子。方法：评估来自 95 名 SVC 患者的服务水平数据。使用了描述性统计、假设检验和线性回归模型。主要临床结果是语音相关的痛苦。估计参与度和事后效应大小；探索了相关的预测因素。结果：59% 的患者在 SVC 内完成了组 PBCT，而在 M4V 内完成了 72%。与未完成者相比，SVC 内完成者的基线抑郁评分较低。与语音相关的痛苦有显着改善（Cohen'sd= –0.47；p= 0.001), 主观恢复 (Cohen'sd= 0.35; p = 0.001) 和抑郁症 (Cohen'sd= –0.20；p= 0.044); 这些结果与 M4V 相当。较高的基线主观恢复和较低的抑郁都预示着语音相关痛苦的改善。SVC 内的治疗费用平均为每位患者 214 英镑。结论：PBCT 组可以在常规临床实践中进行跨诊断。与 RCT 相比，参与度较低，但结果具有可比性。所涉及的资源水平低表明团体 PBCT 可以提供物有所值。
