Abstract：
We examined whether people with high BMI sampled from two different countries were more susceptible to behavioural change via an implicit, rather than explicit, intervention. We measured BMI and used three types of cue interventions (implicit vs explicit healthy lifestyle cue vs neutral cue) to examine their impact on our participants\' food choice using the Fake Food Buffet. Healthiness of the meal chosen was measured by the percentage of healthy food items in the meal. Portion size of their chosen meal was operationalised by the total number of food items chosen and its total calorie content was also estimated. Participants were recruited from the United Kingdom (N = 264) and Indonesia (N = 264). Our results indicated that while explicit food cues were overall more effective, implicit cues were a more effective strategy to change food choice behaviours among individuals with high BMI. Participants with high BMI were more likely to regulate the healthiness of their meal and less likely to regulate its portion size or calorie content. The efficacy of our healthy eating interventions was cross-culturally generalizable. Our study supports previous research that implicit cues of a healthy lifestyle might be a more effective behavioural change strategy for individuals with high BMI.
摘要：
我们检查了来自两个不同国家的高BMI样本的人是否更容易受到行为变化的影响，而不是明确的，干预。我们测量了BMI，并使用了三种类型的提示干预措施（内隐与外显的健康生活方式提示与中性提示），以检查它们对参与者使用假食物自助餐的食物选择的影响。所选择的膳食的健康状况通过膳食中健康食品的百分比来衡量。他们选择的膳食的份量是通过选择的食物项目的总数来操作的，并且还估计了其总卡路里含量。参与者来自英国（N=264）和印度尼西亚（N=264）。我们的结果表明，虽然明确的食物提示总体上更有效，内隐提示是改变高BMI个体食物选择行为的更有效策略.高BMI的参与者更有可能调节膳食的健康状况，而不太可能调节膳食的份量或卡路里含量。我们的健康饮食干预措施的效果是跨文化的。我们的研究支持先前的研究，即健康生活方式的内隐提示可能是高BMI个体更有效的行为改变策略。
