Research has shown that the triarchic model of grit scale (TMGS)—a measure that assesses tendency to show perseverance, passion, and adaptability for long-term goals—has been valid in different contexts such as the Philippines, Japan, Poland, mainland China, and the United States. However, there is limited research on the validity of this scale in Hong Kong. Against this backdrop, this research examined the structural, convergent, and criterion-related of the TMGS among secondary school students in Hong Kong. A total of 298 secondary school students in Hong Kong participated in this study. Confirmatory factor analysis (CFA) was used to evaluate the structural validity of the three-factor model of grit. Correlational analysis was conducted between grit's dimensions and school satisfaction to assess the criterion-related validity of this scale. CFA showed that the scores from the three-factor model of grit underpinned by perseverance of effort, consistency of interests, and adaptability to situations were valid and reliable. There was mixed evidence on the convergent validity of the scale based on the subscales’ composite reliability (CR) estimates. Whereas perseverance of effort and adaptability to situations were positively correlated to school satisfaction, consistency of interests was negatively linked to the said criterion variable. This research demonstrates the potential applicability of the TMGS in Hong Kong. Copyright © 2023 The Authors. Psychology in the Schools Published by Wiley Periodicals LLC.

Studies have shown that the School Kindness Scale (SKS) has adequate psychometric properties in different societies such as Canada, Turkey, and the Philippines. However, there is scarce evidence on the psychometric validity of this scale across multiple societies and educational contexts. This study explores the cross-national invariance of the SKS among high school students in the Philippines, Hong Kong, and mainland China. Results showed that the modified unidimensional model of school kindness with correlated error terms on item number 2 and 3 had the most optimal fit. There was evidence supporting partial invariance of the modified unidimensional model of school kindness across setting and year level, and full invariance across gender. Whereas school kindness also demonstrated positive correlations with perceived academic performance in Hong Kong and mainland China, this construct was linked to higher emotional and social engagement in math in all contexts.
