The changes in appearance of people living with HIV/AIDS (PLHA) interferes with how people around them react to their body, how social interactions take place, and how each person perceives and accepts their body. The definition of itself can be severely challenged when the body changes as a result of illness and the person does not look healthier anymore. People living with HIV/AIDS (PLHA) are an especially vulnerable group when it comes to "distress" and the psychosocial impact of appearance, yet the assessment of body image changes in these people was subjective in Brazil. The aim of this paper was to assess the psychometric properties of the Brazilian version of Derriford Appearance Scale 24 (DAS-24) for a sample of Brazilians living with HIV/AIDS. A sample of 400 patients were recruited from an HIV/AIDS ambulatory, aged between 18 and 78 years, of both sexes. The psychometric properties of DAS-24 were investigated while using confirmatory factor analysis (CFA), with unweighted least square estimation and listwise deletion for missing data. The adjustment of three structural models previously established for DAS-24 (single-factor, two-factor, and three-factor) was investigated. Evidences of construct validity-convergent and discriminant-and internal consistency-Cronbach's alpha and construct reliability-were also generated for the measure model. The results showed that the one-factor model had the best adjustment, after eliminating items 8, 17, and 20, and accepting the covariance of errors between items 4 and 10; 9 and 23; 11 and 14; and, 14 and 22. Additionally, validity and reliability evidence were satisfactory for the model. The Brazilian Portuguese version of DAS-24 seems to be a psychometrically sound scale for measuring body image distress for people living with HIV/AIDS (PLHA).
感染艾滋病毒/艾滋病者（PLHA）外表的变化会影响周围人对其身体的反应方式、社会互动的发生方式，以及每个人对自身身体的认知和接受程度。当身体因疾病而发生变化，且此人看起来不再健康时，身体本身的定义可能会受到严峻挑战。在“苦恼”以及外表的心理社会影响方面，感染艾滋病毒/艾滋病者（PLHA）是一个特别脆弱的群体，然而在巴西，对这些人的身体意象变化的评估是主观的。本文旨在评估巴西版德里福德外表量表24（DAS - 24）在一组感染艾滋病毒/艾滋病的巴西人中的心理测量特性。从一个艾滋病毒/艾滋病门诊招募了400名患者作为样本，年龄在18至78岁之间，男女皆有。在使用验证性因素分析（CFA）时，对DAS - 24的心理测量特性进行了研究，采用未加权最小二乘法估计和对缺失数据的列删除法。研究了先前为DAS - 24建立的三个结构模型（单因素、双因素和三因素）的拟合情况。还为测量模型生成了结构效度（收敛效度和区分效度）以及内部一致性（克朗巴赫α系数）和结构可靠性的证据。结果表明，在剔除第8、17和20项，并接受第4和10项、9和23项、11和14项以及14和22项之间的误差协方差后，单因素模型拟合最佳。此外，该模型的效度和信度证据令人满意。巴西葡萄牙语版的DAS - 24似乎是一个在心理测量上合理的量表，可用于测量感染艾滋病毒/艾滋病者（PLHA）的身体意象苦恼。
