Recent studies on transdiagnostic processes consider eating disorder (ED) examples of psychological inflexibility. To date, the instrument most widely used to evaluate self-concealment is the Self-Concealment Scale (SCS), although there is as yet no Spanish adaptation of the instrument. The objective of this study was to adapt and study evidence of validity of the SCS to the adolescent population in Spain.
A sample of 230 Spanish adolescents aged 13 to 19 years (Mean (M) = 15.52; Standard deviation (SD) = 1.13) was used to study the psychometric properties of the SCS. The discriminative capacity of the items was analyzed, their unidimensional factorial structure was confirmed, the reliability of the scores was studied, and evidence of validity in relation to other clinical variables was examined.
As in the original scale, confirmatory factor analysis showed adequate fit of the 10-item one-dimensional model (Standardized Root Mean Square Residual (SRMSR) = 0.05; comparative fit index (CFI) = 0.90). Body image inflexibility, and to a lesser extent, self-concealment, explained 52.2% of the variance in risk of ED.
It was concluded that the Spanish version of the SCS has adequate psychometric properties and may be a useful tool in evaluating risk of ED in adolescents.
近期关于跨诊断过程的研究将饮食失调（ED）视为心理灵活性不足的例子。迄今为止，评估自我隐瞒最广泛使用的工具是自我隐瞒量表（SCS），不过该量表尚无西班牙语版本。本研究的目的是对SCS进行改编，并研究其在西班牙青少年人群中的效度证据。
选取230名年龄在13至19岁的西班牙青少年样本（均值（M）=15.52；标准差（SD）=1.13），以研究SCS的心理测量特性。分析了项目的区分能力，确认了其一维因子结构，研究了得分的可靠性，并检验了与其他临床变量相关的效度证据。
与原始量表一样，验证性因素分析表明10项一维模型拟合良好（标准化均方根残差（SRMSR）=0.05；比较拟合指数（CFI）=0.90）。身体意象灵活性不足，以及程度较轻的自我隐瞒，解释了饮食失调风险中52.2%的方差。
得出结论，SCS的西班牙语版本具有足够的心理测量特性，可能是评估青少年饮食失调风险的有用工具。
