There is a paucity of effective intervention tools for overweight/obese women to assess, guide and monitor their eating behavior. This study aimed to develop a lifestyle intervention tool, assess its acceptability and usefulness, and verify its construct validity in overweight/obese women. The 6P tool (Portion, Proportion, Pleasure, Phase, Physicality, Psychology) was developed and 15 women with a body mass index (BMI) ≥ 25 kg/m were interviewed to assess its perceived acceptability and usefulness. Subsequently, the revised 6P tool was tested in 46 women with a BMI ≥ 25 kg/m. The Three-Factor Eating Questionnaire (TFEQ), International Physical Activity Questionnaire-Short (IPAQ), and weight were measured at baseline and one-month. Most participants were satisfied with the presentation of the 6P tool (86.8%), and agreed it was useful in guiding healthy eating (81.6%) and raising awareness of eating behavior (97.4%). There were significant improvements in cognitive restraint ( = 0.010) and disinhibition ( = 0.030) (TFEQ), portion size (P1), pleasure behaviors (P3), and total composite 6P score ( < 0.001). However, there was no significant reduction in weight or increase in physical activity. The 6P tool is acceptable and presents with good validity for assessing lifestyle behaviors.
针对超重/肥胖女性，目前缺乏有效的干预工具来评估、指导和监测其饮食行为。本研究旨在开发一种生活方式干预工具，评估其可接受性和有用性，并验证其在超重/肥胖女性中的结构有效性。开发了 6P 工具（份量、比例、愉悦、阶段、体力活动和心理），并对 15 名 BMI≥25kg/m2 的女性进行了访谈，以评估其感知的可接受性和有用性。随后，对 46 名 BMI≥25kg/m2 的女性进行了修订后的 6P 工具测试。在基线和一个月时测量了三因素饮食问卷（TFEQ）、国际体力活动问卷-短卷（IPAQ）和体重。大多数参与者对 6P 工具的呈现方式表示满意（86.8%），并同意它在指导健康饮食（81.6%）和提高对饮食行为的认识（97.4%）方面很有用。认知约束（ = 0.010）和抑制解除（ = 0.030）（TFEQ）、份量（P1）、愉悦行为（P3）和总分 6P 评分（<0.001）均有显著改善。然而，体重或体力活动没有显著减少。6P 工具是可以接受的，并且在评估生活方式行为方面具有良好的有效性。
