The 18-item Mental Toughness Questionnaire (MTQ-18) is a brief, widely used measure of mental toughness. The MTQ-18 derives from the longer MTQ-48, which comprises four independent but correlated factors (challenge, commitment, control, and confidence). Despite sampling items from across MTQ-48 dimensions, the MTQ-18 (as intended) provides a global, unidimensional score. Researchers have recently developed a further abridged version of the MTQ-18, the MTQ-10, which has demonstrated promising psychometric performance. The current paper assessed the factorial structure, reliability, predictive validity and invariance of the MTQ-18 and MTQ-10 in a sample of 944 students from English independent schools (year 11, aged 16 years). Respondents completed the MTQ-18 items online alongside the Satisfaction with Life Scale. Confirmatory factor analysis revealed that the MTQ-10 was a superior general measure, because the MTQ-18 possessed additional variance to that accounted for by an unidimensional solution. Additionally, the MTQ-10 evidenced higher factor loadings and demonstrated better data-model fit. Tests of concurrent validity revealed the MTQ-10 was a stronger predictor of well-being (life satisfaction). Both the MTQ-18 and MTQ-10 demonstrated gender invariance at the configural, metric, and scalar level. Overall, although the MTQ-18 was a psychometrically acceptable measure, the MTQ-10 was a superior unidimensional measure of MT.
18项心理韧性问卷（MTQ - 18）是一种简短且被广泛使用的心理韧性测量工具。MTQ - 18源自更长的MTQ - 48，MTQ - 48包含四个独立但相关的因素（挑战、承诺、控制和信心）。尽管MTQ - 18从MTQ - 48的各个维度选取项目，但它（正如预期的那样）提供一个整体的单维度得分。研究人员最近开发了MTQ - 18的进一步简化版本MTQ - 10，其心理测量性能已显示出良好前景。本文在944名英国私立学校学生（11年级，16岁）样本中评估了MTQ - 18和MTQ - 10的因子结构、信度、预测效度和不变性。受访者在线完成MTQ - 18项目以及生活满意度量表。验证性因子分析表明，MTQ - 10是一种更优的总体测量工具，因为MTQ - 18除了单维度解决方案所解释的方差外还具有额外方差。此外，MTQ - 10显示出更高的因子载荷，并表现出更好的数据 - 模型拟合。同时效度检验表明，MTQ - 10是幸福感（生活满意度）更强的预测指标。MTQ - 18和MTQ - 10在构型、度量和标量水平上均表现出性别不变性。总体而言，尽管MTQ - 18在心理测量学上是可接受的测量工具，但MTQ - 10是心理韧性更优的单维度测量工具。
