An English version was cross-validated in Brunei Darussalam with samples of 644 Grade 10 chemistry students(Riah& Fraser, 1998) and 1,188 Form 5 science students (Khine& Fisher, 2001). In Singapore, Fraser and Chionh(2000) reported strong validity and reliability for both an actual and a preferred form of the WIHIC when it was responded to by sample of 2,310 students in 75 senior high school classes.
