“…Given this, detailed psychometric properties of the CAAS-SF among the Grade 7 SEN students remain unknown. Furthermore, the two scholars focused on mainly three major types of SEN: “attention-deficit/hyperactivity disorder ( n = 114, 33.0%), reading/writing difficulties ( n = 102, 29.6%), and speech/language difficulties ( n = 58, 16.8%)” ( Yuen and Chan, 2022 , p. 8). Given that the types of SEN students integrated into regular classes have reached nine types 1 in Hong Kong ( Education Bureau, 2021 ), for more implications of validating an instrument, it would be more meaningful for researchers to include more SEN types than only three and more grades than only grade 7 in further research.…”
