摘要
重度抑郁障碍(MDD)是一种常见的疾病,复发率高。预防性认知疗法(PCT)已被证明可以延长复发时间,并降低复发风险(s)超过2-10年的复发性抑郁症患者。目的:本研究的目的是检查PCT在20年内首次复发的时间、首次复发的累积比例、无抑郁时间的百分比、平均复发严重程度和患者复发次数的有效性。方法:复发性重度抑郁症的成年人被随机分配到PCT或常规治疗(TAU)组。临床结果评估使用SCID超过20年。我们使用了Cox回归分析、Kaplan-Meier分析、方差分析和负二项回归,并测试了与既往发作次数的相互作用。结果:既往发作次数与治疗条件、首次复发时间存在显著交互作用(Wald[1, n = 172] = 8.840, p = 0.003)。对于既往发作超过3次的参与者,PCT的平均复发时间为4.8年,TAU为1.6年;PCT首次复发的累计比例为87.5%,TAU为100%。对于既往发作超过3次的参与者,探索性分析表明,与TAU相比,PCT的复发率降低了53%,无抑郁时间的百分比显著高于TAU。对平均严重程度没有显著影响。结论:在长达20年的时间里,对于既往发作超过3次的MDD患者,与TAU相比,接受PCT的患者首次复发的时间明显更长,复发风险更低,复发率更低,无抑郁时间更长。这表明PCT具有长达20年的长期保护作用。
Effects up to 20-Year Follow-Up of Preventive Cognitive Therapy in Adults Remitted from Recurrent Depression: The DELTA Study.
Introduction: Major depressive disorder (MDD) is common, and recurrence rates are high. Preventive Cognitive Therapy (PCT), has been shown to prolong time to recurrence and reduce risk of recurrence(s) over 2-10 years in patients with recurrent depression.
Objective: The aim of the study was to examine the effectiveness of PCT over 20 years on time to first recurrence, cumulative proportion of first recurrences, percentage of depression-free time, mean severity of recurrences, and the number of recurrences within a patient.
Methods: Adults remitted from recurrent MDD were randomized to PCT or Treatment As Usual (TAU). Clinical outcomes were assessed using the SCID over 20 years. We used Cox regression analyses, Kaplan-Meier analyses, ANOVA, and negative binomial regression and tested for interaction with the number of previous episodes.
Results: There was a significant interaction effect for number of previous episodes with treatment condition on time to first recurrence (Wald[1, n = 172] = 8.840, p = 0.003). For participants with more than 3 previous episodes, the mean time to recurrence was 4.8 years for PCT versus 1.6 years for TAU; the cumulative proportion of first recurrences was 87.5% for PCT and 100% for TAU. For participants with more than 3 previous episodes, exploratory analyses suggest that PCT had 53% less recurrences and percentage of depression-free time was significantly higher compared to TAU. There were no significant effects on mean severity.
Conclusions: Up to 20 years, for MDD patients with more than 3 previous episodes, those who received PCT had significantly longer time to a first recurrence and lower recurrence risk and may have less recurrences and more depression-free time compared to TAU. This suggests long term protective effects of PCT up to 20-years.
