Positive psychology focuses on enhancing attitudes and behaviors that support well-being, with a key pillar being the use of psychological strengths for optimal functioning. This is linked to positive outcomes such as increased happiness and life satisfaction.
This study aimed to evaluate the psychometric validity of the French adaptation of the Strengths Use Scale (SUS), a self-report tool measuring how individuals use their strengths in daily life. The original SUS, developed by Govindji and Linley (2007), has not been thoroughly assessed across languages and cultures.
The French SUS's psychometric properties were examined using data from six independent French-speaking Canadian samples ( = 1397). After removing cases with missing data, exploratory factor analysis (EFA) was conducted on a subsample to establish the optimal factor structure. Confirmatory factor analysis (CFA) was then performed to assess the factor structure's goodness-of-fit.
Both EFA and CFA supported a unidimensional structure of the scale. The French SUS demonstrated good internal consistency (α = .94). The one-factor model yielded an RMSEA of .122, indicating some model misspecification. However, allowing residuals of some items to covary improved the model fit (RMSEA = .077).
The adapted French SUS exhibits similar properties to the original and presents no new consistency issues. This study contributes to adapting and validating the SUS in French for research and clinical practice. Future research should focus on developing a shorter version by eliminating redundancies and adapting the scale for children to evaluate positive psychology interventions' efficacy in youth.
积极心理学专注于增强支持幸福感的态度和行为，其关键支柱之一是利用心理优势实现最佳功能。这与诸如增加幸福感和生活满意度等积极结果相关联。
本研究旨在评估法语版优势利用量表（SUS）的心理测量效度，这是一种自我报告工具，用于测量个体在日常生活中如何运用自身优势。由戈文德吉和林利（2007年）开发的原始SUS尚未在跨语言和文化中得到全面评估。
使用来自六个独立的加拿大法语样本（n = 1397）的数据检查法语SUS的心理测量特性。在去除缺失数据的案例后，对一个子样本进行探索性因素分析（EFA）以建立最佳因素结构。然后进行验证性因素分析（CFA）以评估因素结构的拟合优度。
EFA和CFA均支持该量表的单维结构。法语SUS表现出良好的内部一致性（α = 0.94）。单因素模型的RMSEA为0.122，表明存在一些模型设定错误。然而，允许一些项目的残差协变改善了模型拟合（RMSEA = 0.077）。
改编后的法语SUS表现出与原始量表相似的特性，并且没有出现新的一致性问题。本研究有助于在法语环境中对SUS进行改编和验证，以用于研究和临床实践。未来的研究应专注于通过消除冗余来开发一个更短的版本，并使该量表适用于儿童，以评估积极心理学干预对青少年的效果。
