Abstract

The psychometric properties of the Indonesian version of the 18-item Mental Toughness Questionnaire (MTQ-18) remain vague. This study uses the Rasch model to elucidate these properties. In addition, boosting classification was adopted to assess the predictive validity of athletes’ achievement. The sample size comprised 400 athletes. According to the Martin-Loef likelihood-ratio test = 482, p = 1.0 and factor analysis of the Rasch residuals, the questionnaire tends to make unidimensional assumptions. The MADaQ3 = 0.074 shows the overall tendency of local independency across all items, with the majority clustered in moderate to low-level measures. Q11, Q15, and Q18 were clearly identified as showing gender bias, with significant effect sizes. According to the boosting classification, the performance between national vs no achievement (F1 = 0.7, AUC = 0.56) and international vs no achievement (F1 = 0.62, AUC = 0.58) was flagged as unsatisfactory predictive performance. In conclusion, the abridged questionnaire is not preferable for determining an individual’s future performance or achievement. Future studies are needed to develop a better version that is more unimpeded by gender bias, and to resolve the variability of the items.

Abstract

Although common spaces in a university can serve an important role for adolescents in learning with colleagues and developing their ideas, common spaces have received insufficient research attention. Therefore, this study identified the characteristics of physical environments that promote active leaning among university students and the psychological aspects of students’ modes of being in common spaces. We conducted an online questionnaire and analyzed the data (N = 144; 86 men and 58 women; mean age = 23.5 ± 5.8 years) using cluster analysis and text-mining. We revealed three types of physical characteristics that promote students’ active learning and five groups of students’ modes of being in common spaces. The physical and psychological characteristics of the common spaces that promote active learning are discussed.
