Intervention programs for treating adiposity which focus on dietary change and physical exercise often do not lead to the desired long-term reduction in weight. This article reports on the effectiveness of M.O.B.I.L.I.S., a standardized theory-driven intervention program. Participants are taught cognitive-behavioral strategies of goal setting, action planning, barrier management, and self-monitoring. Persons with obesity (N=316) responded to a public advertisement to participate in the intervention program (IG) or comparison group (CG; quasi-experimental design). Assessments were conducted at four time points, with the last assessment being conducted two years after baseline. At the 24-month follow-up, the IG showed weight loss of 5.57%, whereas the CG lost 1.12% of their weight (t1-t4, p < .01). The results yielded significant interaction terms (group x time), indicating that the intervention had a substantial effect on food choice and level of physical exercise (p < .01). The IG showed significantly enhanced self-efficacy, stronger goal intentions, and more detailed implementation intentions than the CG at follow-ups. The intervention program has the potential to evoke enduring changes in the cognitions we hypothesized to be responsible for inducing obese adults to begin and continue regular exercise and healthy eating behavior, resulting in substantial weight loss.
针对饮食改变和体育锻炼的肥胖干预计划通常无法实现预期的长期减重效果。本文报告了标准化理论驱动干预计划 M.O.B.I.L.I.S. 的有效性。该计划教授肥胖者认知行为策略，包括目标设定、行动计划、障碍管理和自我监测。肥胖者（N=316）响应了一则公开广告，参加干预组（IG）或对照组（CG；准实验设计）。在四个时间点进行评估，最后一次评估在基线后两年进行。在 24 个月的随访中，IG 的体重减轻了 5.57%，而 CG 减轻了 1.12%（t1-t4，p<.01）。结果显示出显著的交互效应（组 x 时间），表明干预对食物选择和体育锻炼水平有实质性影响（p<.01）。在随访中，IG 显示出比 CG 更高的自我效能、更强的目标意图和更详细的实施意图。该干预计划有可能引起我们假设的认知变化，这些变化促使成年肥胖者开始并持续进行有规律的锻炼和健康的饮食习惯，从而导致显著的体重减轻。
