In a 3rd meta-analysis of the effect of adding hypnosis to cognitive-behavioral treatments for weight reduction, additional data were obtained from authors of 2 studies, and computational inaccuracies in both previous meta-analyses were corrected. Averaged across posttreatment and follow-up assessment periods, the mean weight loss was 6.00 lbs. (2.72 kg) without hypnosis and 11.83 lbs. (5.37 kg) with hypnosis. The mean effect size of this difference was 0.66 SD. At the last assessment period, the mean weight loss was 6.03 lbs. (2.74 kg) without hypnosis and 14.88 lbs. (6.75 kg) with hypnosis. The effect size for this difference was 0.98 SD. Correlational analyses indicated that the benefits of hypnosis increased substantially over time (r = .74).
在对催眠辅助认知行为疗法治疗体重减轻效果的第三次荟萃分析中，从两项研究的作者处获取了更多数据，并纠正了前两次荟萃分析中的计算错误。在治疗后和随访评估期的平均数据显示，未使用催眠时平均体重减轻6.00磅（2.72千克），使用催眠时平均体重减轻11.83磅（5.37千克）。这种差异的平均效应大小为0.66标准差。在最后评估期，未使用催眠时平均体重减轻6.03磅（2.74千克），使用催眠时平均体重减轻14.88磅（6.75千克）。这种差异的效应大小为0.98标准差。相关性分析表明，催眠的益处会随着时间大幅增加（r = 0.74）。
