The Physical Appearance Comparison Scale (PACS [14]) is the most commonly used validated measure of body-related social comparison habits. Here we investigate reliability and construct validity of the PACS in a German sample. Participants (n=75 men, n=75 women and n=25 women with a confirmed diagnosis of anorexia nervosa) completed the PACS along with measures of eating disorder pathology, body image and self-esteem. Results show an adequate internal consistency of the PACS for the female subgroups and medium to high correlations with eating disorder pathology, body image and self-esteem. PACS total score differed significantly between groups, with men scoring lowest and women with anorexia nervosa scoring highest. We conclude that the PACS is a sufficiently reliable and valid measure of body-related social comparison habits in women. In men, it should only be used with special care. The PACS is generally suitable to promote patient studies testing the role of social comparisons for the patho-mechanisms of eating disorders.
身体外貌比较量表（PACS [14]）是最常用的经过验证的与身体相关的社会比较习惯测量工具。在此，我们在一个德国样本中研究了PACS的信度和结构效度。参与者（75名男性、75名女性以及25名确诊为神经性厌食症的女性）完成了PACS以及饮食失调病理学、身体意象和自尊的测量。结果显示，PACS在女性亚组中有足够的内部一致性，并且与饮食失调病理学、身体意象和自尊有中度到高度的相关性。PACS总分在各组之间存在显著差异，男性得分最低，神经性厌食症女性得分最高。我们得出结论，PACS是女性与身体相关的社会比较习惯的一种足够可靠且有效的测量工具。对于男性，使用时应格外谨慎。PACS总体上适合促进患者研究，以检验社会比较在饮食失调病理机制中的作用。
