To traslate and validate of the Brazilian version of the SDI-2.
This was a cross-sectional study. The cultural adaptation considered the stages of initial translation, synthesis of translations, evaluation by a committee of experts from different regions of Brazil, back-translation, and pre-test. The content validity and psychometric proprieties was assessed.
Ten specialists participated in the cultural adaptation of the SDI-2. The content validity showed a Content Validity Ratio (CVR) ≥ 0.75 ( = 0.05). A total of 674 subjects participated in the field study. The Exploratory Factorial Analysis (EFA) presented factor loads ≥ 0.445, and commonalities ≥ 0.40; and two dimensions represented 77% of the total variance explained. The Confirmatory Factorial Analysis CFA presented /df = 4.265; the Root Mean Square Error of Approximation RMSEA = 0.110; the Non-Normed Fit Index NNFI = 0.946; the Comparative Fit Index (CFI) = 0.963; the Goodness of Fit Index GFI = 0.986; and the Adjusted Goodness of Fit Index AGFI = 0.979 for a two-factor model. The coefficient values for the total SDI-2 score were 0.91 for Cronbach's alpha, 0.91 for McDonald's Omega, and 0.97 for the Greatest Lower Bound GLB coefficients. The invariance between sexes was 0.01 for the ΔCFI and ΔRMSEA, showing model stability for these two populations.
The Brazilian version of the SDI-2 is self-report, valid, reliable and invariant across sex.
翻译和验证巴西版 SDI-2。
这是一项横断面研究。文化适应考虑了初始翻译、翻译综合、来自巴西不同地区的专家委员会评估、反向翻译和预测试等阶段。评估了内容效度和心理测量特性。
10 名专家参与了 SDI-2 的文化适应。内容效度显示内容效度比（CVR）≥0.75（=0.05）。共有 674 名受试者参与了现场研究。探索性因素分析（EFA）显示因子负荷≥0.445，共性≥0.40；两个维度代表了总方差的 77%。验证性因素分析（CFA）显示 /df = 4.265；近似均方误差 RMSEA = 0.110；非归一拟合指数 NNFI = 0.946；比较拟合指数（CFI）= 0.963；拟合优度指数（GFI）= 0.986；以及调整后的拟合优度指数（AGFI）= 0.979 的两因素模型。SDI-2 总分的系数值为 Cronbach's alpha 的 0.91，McDonald's Omega 的 0.91，以及 Greatest Lower Bound GLB 系数的 0.97。性别之间的不变性为 ΔCFI 和 ΔRMSEA 的 0.01，表明该模型在这两个群体中具有稳定性。
巴西版 SDI-2 是一种自我报告的、有效的、可靠的、性别不变的工具。
