Abstract

ABSTRACT Objective This study aimed to estimate the psychometric properties of the Body Area Scale (BAS) applied to a sample of Brazilian university students to support the validity and reliability of the obtained data. Methods We performed confirmatory factor analysis (CFA) using the Comparative Fit index (CFI), Tucker-Lewis index (TLI), and Root Mean Square Error of Approximation (RMSEA). We calculated the average variance extracted (AVE), composite reliability (CR), and ordinal alpha coefficient (α). All estimates were calculated separately for women and men. A thousand students participated (women = 64.0%, mean [M] age = 20.92, standard deviation [SD] = 2.40 years; body mass index (BMI) M = 23.24, SD = 3.97 kg/m2). Results Considering the CFA results, the original unifactorial model (24 items) did not fit data for women and men. Instead, the two-factorial model with 19 items had adequate fit for male and female samples (CFI = 0.922-0.958; TLI = 0.912-0.952; RMSEA = 0.090-0.096), as well as good convergent validity (AVE = 0.536-0.668) and reliability (CR = 0.920-0.952; α = 0.916-0.948). Once BAS was proposed to evaluate satisfaction/dissatisfaction with one’s own body, and considering the reformulation of the factorial model, we proposed a new name for the instrument: Body Appearance (Dis)Satisfaction Scale (BAS-R). Conclusion Professionals can now include the BAS-R in future protocols to evaluate satisfaction/dissatisfaction with the body in Brazilian students.

巴西大学生身体外观（Dis）满意度量表

摘要目的本研究旨在评估应用于巴西大学生样本的身体面积量表（BAS）的心理测量特性，以支持所获得数据的有效性和可靠性。方法采用比较拟合指数（CFI）、Tucker Lewis指数（TLI）和均方根误差（RMSEA）进行验证性因素分析（CFA）。我们计算了提取的平均方差（AVE）、复合可靠性（CR）和有序α系数（α）。所有估计数都是分别为妇女和男子计算的。1000名学生参与了研究（女性=64.0%，平均[M]年龄=20.92，标准差[SD]=2.40岁；体重指数（BMI）M=23.24，SD=3.97 kg/m2）。结果考虑到CFA的结果，原始的单一因素模型（24个项目）不适合女性和男性的数据。相反，包含19个项目的双因子模型对男性和女性样本具有足够的拟合度（CFI=0.922-0.958；TLI=0.912-0.952；RMSEA=0.090-096），以及良好的收敛有效性（AVE=0.536-0.668）和可靠性（CR=0.920-0.952，α=0.916-0.948），并考虑到因子模型的重新表述，我们为该工具提出了一个新的名称：身体外观（Dis）满意度量表（BAS-R）。结论专业人员现在可以将BAS-R纳入未来的方案中，以评估巴西学生对身体的满意度/不满意度。

期刊介绍： O Jornal Brasileiro de Psiquiatria se insere em programas de educação continuada e atualização e tem como missão divulgar trabalhos de pesquisa (realizados em instituições brasileiras e estrangeiras) cujos resultados tenham potencial para a investigação e prática clínica no campo da Psiquiatria. Criado em 1938, foi publicado até 1950, sob o título “Anais do Instituto de Psiquiatria”, sem periodicidade regular.
