register hereIntroduction: Access to evidence-based psychological therapy for posttraumatic stress disorder (PTSD) is limited. Blended Trauma-focused Cognitive Therapy (bTF-CT), merging internet-modules with a few therapy sessions, may be a pathway to enhance treatment access while maintaining the benefits of face-to-face therapy.Objectives: This study aimed to evaluate the feasibility, acceptability, and preliminary effectiveness of bTF-CT for PTSD in routine care, as well as the feasibility of assessments and data collection.

在此注册简介：创伤后应激障碍（PTSD）的循证心理治疗有限。以创伤为中心的混合认知疗法（bTF-CT）将互联网模块与一些治疗课程相结合，可能是一种增强治疗机会的途径，同时保持面对面的治疗的益处。目的：本研究旨在评估bTF CT在常规护理中治疗PTSD的可行性，可接受性和初步有效性，以及评估和数据收集的可行性。

Method: A single-arm design was adopted. bTF-CT was provided to 17 participants across two psychiatric and one primary care clinic. Assessments were conducted pre, during, post and 6months following treatment. We assessed feasibility and acceptability via self-report questionnaires, retention, and attrition rates.

方法：采用单臂设计。bTF CT被提供给两个精神病诊所和一个初级保健诊所的17名参与者。在治疗前，治疗期间，治疗后和治疗后6个月进行评估。我们通过自我报告问卷，保留率和流失率评估了可行性和可接受性。

Preliminary treatment effectiveness was estimated using the PTSD Symptom Checklist (PCL-5) was used to assess PTSD symptom severity. Results: Treatment satisfaction was high with a mean score of 28.7 out of 32 on the Client Satisfaction Questionnaire (SD = 3.5). The dropout rate was low, with 88% treatment retention.

使用PTSD症状检查表（PCL-5）评估初步治疗效果，以评估PTSD症状的严重程度。结果：治疗满意度很高，客户满意度问卷（SD=3.5）的32分平均得分为28.7分。辍学率很低，治疗保留率为88%。

Program adherence was satisfactory, with scores ranging from 2.13 to 3.13 out of 4 on the internet intervention patient adherence scale. On the PCL-5, 88% made a reliable change, 64% demonstrated a clinically significant change, and the mean change from pre to post was 24 points (d = 2.13). Some negative effects were reported, such as unpleasant memories, feelings, and disrupted sleep, but these were temporary according to symptom scales.

项目依从性令人满意，互联网干预患者依从性量表的得分范围为2.13至3.13（满分4分）。在PCL-5上，88%发生了可靠的变化，64%表现出临床上显着的变化，从术前到术后的平均变化为24分（d=2.13）。据报道有一些负面影响，例如不愉快的记忆，感觉和睡眠中断，但根据症状量表，这些是暂时的。

Conclusions: bTF-CT appears to be acceptable, feasible, and potentially effective when delivered in routine care. A large-scale non-inferiority trial to assess effectiveness compar.

结论：bTF CT在常规护理中似乎是可接受的，可行的，并且可能有效。一项大规模的非劣效性试验来评估有效性比较。
