Although evidence-based interventions for posttraumatic stress disorder (PTSD) are highly effective, on average about 20% of patients drop out of treatment. Despite considerable research investigating PTSD treatment dropout in randomized controlled trials (RCTs), findings in naturalistic settings remain sparse.
Therefore, the present study investigated the frequency and predictors of dropout in trauma-focused interventions for PTSD in routine clinical care.
The sample included = 195 adults with diagnosed PTSD, receiving trauma-focused, cognitive behavioral therapy in routine clinical care in three outpatient centers. We conducted a multiple logistic regression analysis with the following candidate predictors of dropout: patient variables (e.g., basic sociodemographic status and specific clinical variables) as well as therapist's experience level and gender match between therapist and patient.
Results showed a dropout rate of 15.38%. Age (higher dropout probability in younger patients) and living situation (living with parents predicted lower dropout probability compared to living alone) were significant predictors of dropout. Dropout was not significantly associated with the therapist's experience level and gender match.
In conclusion, routinely assessed baseline patient variables are associated with dropout. Ultimately, this may help to identify patients who need additional attention to keep them in therapy.
尽管基于证据的创伤后应激障碍（PTSD）干预措施非常有效，但平均约20%的患者会退出治疗。尽管在随机对照试验（RCT）中对PTSD治疗退出情况进行了大量研究，但在自然环境中的研究结果仍然很少。
因此，本研究调查了常规临床护理中针对PTSD的创伤聚焦干预措施中退出治疗的频率和预测因素。
样本包括195名被诊断为PTSD的成年人，他们在三个门诊中心接受常规临床护理中的创伤聚焦认知行为疗法。我们进行了多元逻辑回归分析，以下是退出治疗的候选预测因素：患者变量（如基本社会人口统计学状况和特定临床变量）以及治疗师的经验水平和治疗师与患者之间的性别匹配。
结果显示退出率为15.38%。年龄（年轻患者退出可能性更高）和生活状况（与独自生活相比，与父母同住预测退出可能性更低）是退出治疗的显著预测因素。退出治疗与治疗师的经验水平和性别匹配没有显著关联。
总之，常规评估的基线患者变量与退出治疗有关。最终，这可能有助于识别需要额外关注以使其继续接受治疗的患者。
