The present study developed a Brazilian adaptation of the BAS for young adolescents, testing its factor structure by the Confirmatory Factor Analysis (CFA), concurrent and criterion validity, and its internal consistency. Participants were 347 adolescents (171 male and 176 female, aged between 10 and 13 years old). Three psychologists experts in psychological evaluation and three teachers of Portuguese of elementary school also participated for the adaptation stage of the items in order to be properly understood by the sample age group. There were few changes from the version culturally adapted for the Brazilian adult population. Cronbach's alpha coefficients were satisfactory for the general population and both sexes (.804; female =.851; male =.752). The one-factor model of the BAS was confirmed by the confirmatory factor analysis with good indicators for the measurements of adjustment to the model, χ2 = 77.9; GFI = 0.967; NFI = 0.940, CFI = 0.979; TLI = 0.968; RMSEA;.038). The convergent validity analyzes revealed significant correlations between BAS scores and BMI (r = -.230; p < .001) and between the first and body image satisfaction (r = .309; p < .001). The BAS version for Brazilian young adolescents had adequate levels of validity and reliability, keeping the one-dimensional structure which indicates its use in Brazilian adolescent's samples.
本研究对青少年版的BAS进行了巴西本土化改编,通过验证性因素分析(CFA)检验其因素结构、同时效度和效标效度以及内部一致性。参与者为347名青少年(171名男性和176名女性,年龄在10至13岁之间)。三位心理评估专家和三位小学葡萄牙语教师也参与了项目的改编阶段,以便该年龄段的样本能够正确理解。与针对巴西成年人群体进行文化改编的版本相比,改动很少。总体人群以及男性和女性的克朗巴哈系数均令人满意(.804;女性=.851;男性=.752)。验证性因素分析证实了BAS的单因素模型,模型适配度测量指标良好,χ2 = 77.9;GFI = 0.967;NFI = 0.940,CFI = 0.979;TLI = 0.968;RMSEA =.038)。收敛效度分析显示,BAS得分与BMI之间存在显著相关性(r = -.230;p <.001),与身体意象满意度之间也存在显著相关性(r =.309;p <.001)。巴西青少年版的BAS具有足够的效度和信度水平,保持了一维结构,表明其可用于巴西青少年样本。
