Background Results of behavioral weight-loss treatments vary widely, with mostly unsuccessful outcomes beyond the short term. Women with obesity participating in a new cognitive-behavioral weight-loss treatment were assessed on their responses to psychological targets. Methods Groups of responders ( n = 43) and nonresponders ( n = 48) were established post hoc. Results Age, race/ethnicity, education, income, body composition, physical activity, and eating behaviors at baseline were not discriminated between responders and nonresponders. Over both 6 and 24 months, responders improved significantly more in physical activity and fruit/vegetable consumption but not sweets intake. Weight loss over 6 and 24 months was significantly greater for the responder group at 8.1% and 8.6% versus nonresponders at 4.7% and 3.8%, respectively. Self-regulation change significantly predicted all behavioral changes, with mood change improving the predictive strength for only sweets intake. Discussion Although further research is required to determine the etiology of, and to maximize, positive responses, findings suggested prospects for treatment improvements.
行为减肥治疗的结果差异很大，短期之外大多效果不佳。对参与一项新的认知行为减肥治疗的肥胖女性就其对心理目标的反应进行了评估。方法：事后设立了反应者组（n = 43）和无反应者组（n = 48）。结果：反应者和无反应者在基线时的年龄、种族/民族、教育程度、收入、身体组成、身体活动和饮食行为方面没有差异。在6个月和24个月期间，反应者在身体活动和水果/蔬菜摄入量方面的改善明显更多，但在甜食摄入量方面没有改善。反应者组在6个月和24个月时的体重减轻分别为8.1%和8.6%，显著高于无反应者组的4.7%和3.8%。自我调节变化显著预测了所有行为变化，情绪变化仅提高了对甜食摄入量的预测强度。讨论：尽管需要进一步研究来确定积极反应的病因并使其最大化，但研究结果表明了治疗改进的前景。
