A Chinese version of the Psychological Sense of School Membership (PSSM) scale was developed to find out the subjective PSSM of Mainland immigrant and local Hong Kong students. Five schools participated with 295 boys and 252 girls from Primary years 4, 5, and 6 taking part. Among those, 264 students were local Hong Kong students, while 283 were Mainland immigrant students who claimed that they had lived in Hong Kong for 7 years or less. The Chinese version of the PSSM scale was found to be reliable, and interestingly, Mainland immigrant students were found to have a significantly higher sense of school belonging, but had a lower feeling of rejection than Hong Kong students did. Results would be useful to understand how students feel towards support in school. (Contains 3 tables and 1 figure.) [Appended to this document is: "Appendix 1.
