CONTI, Maria Aparecida; LATORRE, Maria do Rosário Dias de Oliveira; HEARST, Norman  e  SEGURADO, Aluísio. Cross-cultural adaptation, validation and reliability of the Body Area Scale for Brazilian adolescents. Cad. Saúde Pública [online]. 2009, vol.25, n.10, pp.2179-2186. ISSN 0102-311X.  https://doi.org/10.1590/S0102-311X2009001000009.

The aim of this study was to translate, validate and verify the reliability of the Body Area Scale (BAS). Participants were 386 teenagers, enrolled in a private school. Translation into Portuguese was conducted. The instrument was evaluated for internal consistency and construct validation analysis. Reproducibility was evaluated using the Wilcoxon test and the coefficient of interclass correlation. The BAS demonstrated good values for internal consistency (0.90 and 0.88) and was able to discriminate boys and girls according to nutritional state (p = 0.020 and p = 0.026, respectively). BAS scores correlated with adolescents' BMI (r = 0.14, p = 0.055; r = 0.23, p = 0.001) and WC (r =0.13, p = 0.083; r = 0.22, 0.002). Reliability was confirmed by the coefficient of inter-class correlation (0.35, p < 0.001; 0.60, p < 0.001) for boys and girls, respectively. The instrument performed well in terms of understanding and time of completion. BAS was successfully translated into Portuguese and presented good validity when applied to adolescents.
