The aim of this study was to validate the content of a questionnaire in order to assess the attitudes and practices in childcare consultations, knowledge on overweight and obesity, their risk factors, and barriers in addressing the issue by pediatricians and family physicians.
The Delphi technique was used, with the objective of reaching a consensus on a certain subject, through experts' opinions. The content validity index (CVI) of each item, axis, and questionnaire was calculated. The inter-rater reliability was calculated using an agreement coefficient suitable for the answer distribution such as Gwet's AC2 with ordinal weight.
A total of 63 experts were invited to assess and give their opinion on the questionnaire. In all, 52 accepted the invitation and analyzed the instrument. After two rounds, the questionnaire reached the proper CVI for the study and was considered complete, with its final version having 40 questions, a final index of 95%, and an inter-rate reliability of 0.905.
This instrument, developed to assess attitudes and practices, knowledge, and barriers found in addressing the obesity by primary care physicians, obtained a CVI greater than 0.8 and an excellent agreement coefficient of the 52 judges. Therefore, its content can be considered validated.
本研究旨在验证一份调查问卷的内容，以评估儿科医生和家庭医生在儿童保健咨询中对超重和肥胖的态度和实践、相关知识、风险因素，以及解决该问题的障碍。
采用德尔菲法，通过专家意见，旨在就某一主题达成共识。计算了每个项目、轴和问卷的内容效度指数（CVI）。使用适合答案分布的一致性系数（如有序权重的 Gwet 的 AC2）计算了评分者间可靠性。
共邀请了 63 名专家评估并对问卷发表意见。共有 52 名专家接受了邀请并对该工具进行了分析。两轮之后，该问卷达到了研究的适当 CVI，被认为是完整的，最终版本有 40 个问题，最终指数为 95%，评分者间可靠性为 0.905。
本研究开发了一种用于评估初级保健医生在解决肥胖问题方面的态度和实践、知识和障碍的工具，其 CVI 大于 0.8，52 位评审员的一致性系数极好，因此其内容可以认为是有效的。
