This study aimed to test the construct validity of the newly developed Chinese version of the Revised Restraint Scale (RRS) in two separate female samples from Chinese universities (n(1) = 171; n(2) = 158). The RRS is the most widely used measure of restricted eating for the purpose of achieving or maintaining a desired weight. Results showed that the 10-item Chinese RRS comprised of two subscales of concern dieting (CD) and weight fluctuation (WF), which together accounted for 53.01% of the total variance. Confirmative factor analysis supported this two-factor model as an acceptable model (χ(2)/df = 1.545, p < 0.001; RMSEA=0.059, GFI=0.938, and CFI=0.935). Cronbach's alpha coefficients were 0.77 for RRS, 0.71 for CD and 0.66 for WF. Significant correlations were shown between RRS and its subscales ((rRRS-CD) = 0.894, p < 0.01; r(RRS-WF) = 0.850, p < 0.01; r(CD-WF) = 0.523, p < 0.01). Moreover, RS significantly correlated with the Three-Factor Eating Questionnaire-R (TFEQ-R), the Dutch Eating Behaviour Questionnaire-R (DEBQ-R), the Fatness Concern (FC) and the body measure index (BMI) (r = 0.548, p < 0.01; r = 0.631, p < 0.01; r = 0.620, p < 0.01; r = 0.351, p < 0.01, respectively). In sum, the RS has stable factor structure, acceptable internal consistency and satisfactory convergent reliability among female Chinese college students. The adapted scale may serve as a useful tool for identifying restrained and unrestrained eaters among Chinese women and may be particularly useful in assessing eating restraint before and after prevention and intervention programs.
本研究旨在通过来自中国两所大学的两个独立女性样本测试新修订的限制饮食量表（RRS）的中文版的结构效度（n(1) = 171；n(2) = 158）。RRS 是最广泛用于测量为达到或维持理想体重而限制饮食的工具。结果表明，中文版 RRS 由关注节食（CD）和体重波动（WF）两个分量表组成，共占总方差的 53.01%。验证性因子分析支持这一包含两个分量表的模型，该模型具有可接受的拟合度（χ(2)/df = 1.545，p < 0.001；RMSEA=0.059，GFI=0.938，CFI=0.935）。RRS、CD 和 WF 分量表的 Cronbach's α 系数分别为 0.77、0.71 和 0.66。RRS 及其分量表之间存在显著相关性（rRRS-CD = 0.894，p < 0.01；r(RRS-WF) = 0.850，p < 0.01；r(CD-WF) = 0.523，p < 0.01）。此外，RRS 与三因素饮食问卷-R（TFEQ-R）、荷兰饮食行为问卷-R（DEBQ-R）、肥胖担忧（FC）和身体测量指数（BMI）显著相关（r = 0.548，p < 0.01；r = 0.631，p < 0.01；r = 0.620，p < 0.01；r = 0.351，p < 0.01）。总之，RRS 具有稳定的因子结构、可接受的内部一致性和令人满意的聚合可靠性，适用于中国女大学生群体。该改编量表可以作为识别中国女性限制进食者和非限制进食者的有用工具，特别是在预防和干预前后评估进食限制时可能特别有用。
