To compare the outcomes of cognitive therapy for depression under controlled and clinically representative conditions, while holding several therapist and clinical assessment factors constant.
Treatment outcomes for a sample of 23 adults with a primary diagnosis of Major Depressive Disorder who received cognitive therapy in an outpatient clinic were compared with outcomes of 18 clients who were treated in the cognitive therapy condition of a large, multi-site randomized clinical trial of treatments for depression. All participants had been treated by one of two therapists who served as clinicians in both settings. Individuals in the two samples were diagnostically and demographically similar (approximately 50% Female, 83% White). A variety of client characteristics, assessed prior to treatment, as well as the outcomes of treatment, were examined.
Significantly superior treatment outcomes were observed in the individuals treated in the research study, relative to clients in the outpatient clinic, and the difference was not accounted for by intake characteristics. Individuals treated by the therapists in the RCT experienced almost three times as much improvement in depressive symptoms as clients seen in the outpatient setting.
If replicated, the findings suggest that differences exist between treatment outcomes in research and outpatient settings and that these differences may not simply be due to therapist experience and training, or differences in patient populations. Future research should further examine the impact of fidelity monitoring, treatment expectation and motivation, and the duration and timing of treatment protocols on clinical outcomes.
在保持若干治疗师和临床评估因素不变的情况下,比较在受控条件和临床代表性条件下抑郁症认知疗法的治疗效果。
将23名初步诊断为重度抑郁症的成年人在门诊接受认知疗法的治疗效果,与18名在一项大型多地点抑郁症治疗随机临床试验的认知疗法组接受治疗的患者的治疗效果进行比较。所有参与者均由在两种环境中担任临床医生的两名治疗师之一进行治疗。两个样本中的个体在诊断和人口统计学特征上相似(约50%为女性,83%为白人)。对治疗前评估的各种患者特征以及治疗结果进行了检查。
与门诊患者相比,在研究中接受治疗的个体观察到显著更好的治疗效果,且这种差异不能由初始特征来解释。在随机对照试验中接受治疗师治疗的个体,其抑郁症状的改善程度几乎是门诊患者的三倍。
如果研究结果得到重复验证,则表明研究环境和门诊环境中的治疗效果存在差异,且这些差异可能不仅仅归因于治疗师的经验和培训,或患者群体的差异。未来的研究应进一步考察保真度监测、治疗期望和动机,以及治疗方案的持续时间和时机对临床结果的影响。
