CD-RISC Portuguese Validation

The objective of this study was to evaluate the psychometric properties and convergent validity of first Portuguese version of the Connor- Davidson Resilience Scale (CD-RISC, 2003). Data sets came from two studies in Portugal, respectively, 476 participants from the Resilience Effect in Coping with Trauma (RECT) project and 405 participants from the Health Impact Assessment of Employment Strategies (HIAES) project. The original CD-RISC items were translated to Portuguese and used in a survey along with additional psychosocial and biomedical measures. An Exploratory Factorial Analysis (EFA) with each of the two samples revealed that the best solution in both samples had 3 factors - Self-Efficacy, Spirituality and Social Support. A Confirmatory Factor Analysis (CFA) using the two samples together and the 3 factors model specified on the EAF revealed, in absolute, a good overall fit and, comparatively, a better fit than the model with the original 5 factors. The bivariate correlations between the 3 factors and the variables used for the convergent validity are consistent with previous research and show significant correlations with physical activity, medication, mental health, subjective happiness and stress. There may be a protective and beneficial role of positive mental health and resilience on health outcomes.

本研究旨在评估首版葡萄牙语版Connor-Davidson韧性量表（Connor-Davidson Resilience Scale, CD-RISC, 2003）的心理测量学属性与会聚效度。本研究数据集源自葡萄牙的两项独立研究：其一为创伤应对韧性效应（Resilience Effect in Coping with Trauma, RECT）项目，共纳入476名参与者；其二为就业策略健康影响评估（Health Impact Assessment of Employment Strategies, HIAES）项目，共纳入405名参与者。原版CD-RISC条目被译为葡萄牙语，并与额外的社会心理及生物医学测评工具一同用于本次调查。针对两个样本分别开展探索性因素分析（Exploratory Factorial Analysis, EFA），结果显示两个样本的最优因子解均包含3个因子——自我效能感、精神性与社会支持。联合两个样本开展验证性因素分析（Confirmatory Factor Analysis, CFA），并采用探索性因素分析所确定的三因子模型，结果显示整体拟合度良好，且相较于原版5因子模型，拟合效果更优。3个因子与会聚效度检验变量间的双变量相关结果与既往研究一致，且与体力活动、服药状况、心理健康、主观幸福感及压力均存在显著相关。积极心理健康与韧性或许对健康结局具有保护性及有益作用。
