In the Middle East, the prevalence of overweight/obesity is 80%; however, no studies have yet tested the efficacy of interventions to promote weight loss. The aim of the present study was to test the ability of implementation intentions formed using a volitional help sheet to support weight loss among people who were overweight/obese. Participants (N = 216) enrolling in a weight loss program in Kuwait were randomly allocated either to form implementation intentions using a volitional help sheet (intervention group) or to use the volitional help sheet to think about critical situations and appropriate responses but not form implementation intentions (control group). The main outcome measure was weight at 6-month follow-up. Participants in the intervention condition lost significantly more weight (6.15 kg; -6.58% initial body weight) than those in the control condition (3.66 kg; -4.04% initial body weight), M = 2.55% initial body weight, SE = .92, t(214) = 2.76, p = .006, 95%CI = .73, 4.36, d = .38. The present study is the first to show that implementation intentions work beyond a Western context and that the volitional help sheet could be used in a variety of cultural contexts to enhance weight-loss programs.
在中东，超重/肥胖的患病率为 80%；然而，目前还没有研究测试过促进减肥的干预措施的效果。本研究的目的是测试使用意志帮助表制定实施意向以支持超重/肥胖人群减肥的能力。在科威特参加减肥计划的参与者（N=216）被随机分配到使用意志帮助表制定实施意向（干预组）或使用意志帮助表思考关键情况和适当的反应但不制定实施意向（对照组）。主要结果测量是 6 个月随访时的体重。干预组的参与者体重减轻显著更多（6.15 公斤；初始体重的-6.58%），而对照组的参与者体重减轻较少（3.66 公斤；初始体重的-4.04%），M=2.55%初始体重，SE=.92，t（214）=2.76，p=.006，95%CI=.73，4.36，d=.38。本研究首次表明，实施意向在西方背景之外也有效，并且意志帮助表可以在各种文化背景下用于增强减肥计划。
