The Body Acceptance by Others Scale (BAOS) measures the degree to which individuals perceive body acceptance by others, but its factor structure is questionable. Here, we developed a revision of the BAOS (i.e., the BAOS-2) by designing novel items reflective of generalised perceptions of body acceptance by others. In three studies, we examined the psychometrics of the 13-item BAOS-2. Study 1, with United Kingdom adults (N = 601), led to the extraction of a unidimensional model of BAOS-2 scores and provided evidence of 4-week test-retest reliability. Study 2, with United Kingdom adults (N = 423), indicated that the unidimensional model of BAOS-2 scores had adequate fit and that scores were invariant across gender. Study 2 also provided evidence of convergent, construct, criterion, discriminant, and incremental validity. Study 3 cross-validated the fit of the unidimensional model in adults from the United State (N = 503) and provided evidence of invariance across gender and national group. Internal consistency coefficients of BAOS-2 scores were adequate across all three studies. There were no significant gender differences in BAOS-2 scores and a significant national difference had a negligible effect size. Thus, the BAOS-2 is a psychometrically-sound measure that can be utilised in future research.

他人的身体接受量表（BAOS）衡量个人对他人的身体接受程度，但其因素结构值得怀疑。在这里，我们通过设计新颖的物品来反映BAOS（即BAOS-2），该物品反映了他人对身体的普遍认可。在三项研究中，我们检查了13个项目BAOS-2的心理计量学。研究1与英国成年人（N = 601）一起提取了BAOS-2分数的一维模型，并提供了4周重测信度的证据。研究2，与英国成人（N= 423），表明BAOS-2分数的一维模型具有足够的拟合度，并且分数在性别之间是不变的。研究2还提供了收敛，构造，准则，判别和递增效度的证据。研究3交叉验证了来自美国（N = 503）成人一维模型的拟合度，并提供了性别和民族之间不变的证据。在所有三项研究中，BAOS-2评分的内部一致性系数均足够。BAOS-2评分没有明显的性别差异，而全国差异显着，影响大小可忽略不计。因此，BAOS-2是一种可以在未来研究中使用的心理计量方法。
