There are few instruments with good validity and reliability for evaluating body image in children. In this study we aimed to develop and evaluate the psychometric properties of a scale for Brazilian children. In Study 1, we developed 53 items on the basis of a literature review, previous body image scales and qualitative study. We developed the item format and response options and developed instructions for both researchers and participants. In Study 2, we used 10 experts and 21 boys and girls aged 7-11 years ( = 8.25 years, = 1.70) to evaluate item content and semantics. The scale went through further refinement, leading to the exclusion of some items and the modification of others. In Study 3, we analyzed the instrument's psychometric properties in 571 girls ( = 9.17 years of age, = 1.23) and 597 boys ( = 9.32 years, = 1.24) from all over Brazil, using exploratory and confirmatory factorial analyses with independent samples. The scale's final version for females was composed of 17 items divided into five factors; and the final male version included 13 items and two factors. Both versions presented satisfactory convergent and discriminant validity, and these scales can now be used reliably with 7-11 year old Brazilian children.
用于评估儿童身体意象的有效且可靠的工具很少。在本研究中，我们旨在开发并评估一种针对巴西儿童的量表的心理测量特性。在研究1中，我们基于文献综述、先前的身体意象量表和定性研究，编制了53个条目。我们设计了条目格式和回答选项，并为研究人员和参与者制定了指导说明。在研究2中，我们邀请了10位专家以及21名7至11岁的男孩和女孩（平均年龄=8.25岁，标准差=1.70）来评估条目的内容和语义。该量表经过进一步完善，一些条目被排除，另一些则进行了修改。在研究3中，我们对来自巴西各地的571名女孩（平均年龄=9.17岁，标准差=1.23）和597名男孩（平均年龄=9.32岁，标准差=1.24）进行了探索性和验证性因子分析，以分析该工具的心理测量特性。女性版量表的最终版本由17个条目组成，分为五个因子；男性版最终版本包括13个条目和两个因子。两个版本都呈现出令人满意的收敛效度和区分效度，这些量表现在可以可靠地用于7至11岁的巴西儿童。
