We aimed at developing and evaluating a questionnaire assessing health and appearance as the two main reasons for weight loss in overweight and obese individuals.
Using data from two representative telephone surveys in Switzerland, the factorial structure of this questionnaire was analyzed by exploratory and confirmatory factor analysis. The model obtained was cross-validated with data from a second representative Swiss survey and multigroup analyses according to sex, age, BMI and regional language subgroups were performed.
This lead to a 24-item, 3-factor solution, with factors labeled 'health', 'appearance in relation to others', and 'appearance in relation to oneself'. Internal consistency and test-retest reliability were good.
To the best of our knowledge, this is the first validated questionnaire assessing overweight and obese individuals' reasons for weight loss. It should be further tested whether using this questionnaire as a pretreatment assessment device will help in tailoring treatments to individuals, thereby increasing treatment adherence and success.
我们旨在开发并评估一份问卷，以评估超重和肥胖个体减轻体重的两个主要原因，即健康和外貌。
利用来自瑞士两项具有代表性的电话调查的数据，通过探索性和验证性因子分析来分析该问卷的因子结构。利用来自瑞士第二项具有代表性的调查的数据对获得的模型进行交叉验证，并根据性别、年龄、BMI 和地区语言亚组进行多组分析。
由此得出了 24 项、3 个因子的解决方案，这些因子分别标记为“健康”、“与他人相关的外貌”和“与自己相关的外貌”。内部一致性和重测信度均良好。
据我们所知，这是第一个经验证的评估超重和肥胖个体减肥原因的问卷。进一步测试使用该问卷作为预处理评估工具是否有助于针对个体量身定制治疗，从而提高治疗依从性和成功率。
