Abstract

Objective

Interpersonal psychotherapy (IPT) has been proposed as a treatment strategy for eating disorders (EDs). However, cognitive behavioural therapy (CBT) is the treatment more widely used than IPT.

Method

Our study aimed to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) in order to compare the effectiveness of IPT with CBT in treating eating disorders (EDs). To achieve this goal, we conducted a comprehensive search on PubMed, Embase, Medline, Cochrane, Web of Science, and the Clinical Trials Database for RCTs that compared the effectiveness of IPT with CBT in treating EDs.

Results

After reviewing 468 potential studies, we selected 10 suitable for our meta-analysis, which included 833 participants. Results showed that both IPT and CBT had similar effects on the primary outcome measure (i.e., ED score) (SMD = 0.08). However, IPT had a more significant effect on the secondary outcome measure (i.e., Inventory of Interpersonal Problems) (SMD = 0.32) compared to CBT. Additionally, IPT had a better treatment effect for individuals with EDs who had a lower body mass index (SMD = 0.27) and were younger (SMD = 0.43) than those receiving CBT. Both IPT and CBT demonstrated follow-up effects at pretest and after follow-up periods of less than 6 months (SMD = 1.61, 1.83), between 6 and 12 months (SMD = 1.48, 1.65), and greater than 12 months (SMD = 1.29, 1.33). However, only CBT demonstrated a dose–response relationship trend (β = 0.017, p = 0.067).

Conclusions

The meta-analysis yielded compelling evidence that IPT is an effective treatment for individuals with EDs. However, the review highlights the need for future research to further elucidate the effects of IPT on ED treatment.

人际心理疗法与认知行为疗法对饮食失调症的疗效对比：系统回顾与荟萃分析

目的人际心理疗法（IPT）被认为是饮食失调症（ED）的一种治疗策略。然而，认知行为疗法（CBT）是比 IPT 应用更广泛的治疗方法。方法我们的研究旨在对随机对照试验（RCTs）进行系统回顾和荟萃分析，以比较IPT和CBT治疗进食障碍（EDs）的效果。为了实现这一目标，我们在 PubMed、Embase、Medline、Cochrane、Web of Science 和临床试验数据库中进行了全面检索，以寻找比较 IPT 和 CBT 治疗 ED 的有效性的 RCT。结果在审查了 468 项潜在研究后，我们选择了 10 项适合进行荟萃分析的研究，其中包括 833 名参与者。结果显示，IPT 和 CBT 对主要结果指标（即 ED 评分）的影响相似（SMD = 0.08）。然而，与 CBT 相比，IPT 对次要结果测量（即人际关系问题量表）（SMD = 0.32）的影响更为显著。此外，对于体重指数较低（SMD = 0.27）和年龄较小（SMD = 0.43）的 ED 患者，IPT 的治疗效果要好于接受 CBT 的患者。IPT和CBT在测试前和测试后的随访期均显示出治疗效果，随访期分别小于6个月（SMD = 1.61，1.83）、6至12个月（SMD = 1.48，1.65）和大于12个月（SMD = 1.29，1.33）。然而，只有 CBT 显示出剂量-反应关系趋势（β = 0.017，p = 0.067）。结论该荟萃分析提供了令人信服的证据，证明 IPT 是治疗 ED 患者的有效方法。然而，综述强调了未来研究的必要性，以进一步阐明 IPT 对 ED 治疗的效果。
