Bariatric surgery is currently considered the most effective treatment of severe obesity, but considerable individual variations in weight loss results have been reported. We therefore conducted a systematic review and meta-analysis of studies investigating the effect of psychotherapeutic interventions and support groups on weight loss following bariatric surgery. A literature search was conducted in the databases PubMed and PsycINFO, identifying nine eligible studies reporting results of the effect of psychotherapeutic interventions and support groups on weight loss following bariatric surgery. The results revealed a statistically significant overall effect of both psychotherapeutic interventions and support groups on weight loss (pooled effect size correlation (ESr) = 0.18; p < 0.0001). When comparing the effect sizes of psychotherapeutic interventions and support groups, no difference was found (p = 0.51). Higher quality studies had smaller effect sizes (0.16) than studies with low quality scores (0.22), but the difference did not reach statistical significance (p = 0.26). Patients attending psychotherapeutic interventions or support groups in combination with bariatric surgery appeared to experience greater weight loss results than patients treated with bariatric surgery only. However, research in this area is characterized by a lack of methodological rigor, and it is recommended that future study designs include randomization and active attention control conditions.
减重手术目前被认为是治疗重度肥胖症最有效的方法，但据报道，减重效果存在相当大的个体差异。因此，我们对调查减重手术后心理治疗干预和支持小组对减重效果的影响的研究进行了系统回顾和荟萃分析。在 PubMed 和 PsycINFO 数据库中进行了文献检索，确定了 9 项符合条件的研究，这些研究报告了心理治疗干预和支持小组对减重手术后减重效果的影响。结果显示，心理治疗干预和支持小组对减重均有统计学显著的总体效果（汇总效应大小相关系数（ESr）=0.18；p<0.0001）。比较心理治疗干预和支持小组的效果大小，没有发现差异（p=0.51）。高质量研究的效果大小（0.16）小于低质量评分研究的效果大小（0.22），但差异无统计学意义（p=0.26）。与仅接受减重手术治疗的患者相比，接受减重手术联合心理治疗干预或支持小组治疗的患者似乎减重效果更好。然而，该领域的研究存在方法学严谨性不足的问题，建议未来的研究设计包括随机和积极的注意对照条件。
