Verification of Reliability and Validity of a Malaysian Version of Rathus Assertiveness Schedule as Drug Prevention Scale

The aim of this research was to verify the Malaysian version Rathus assertiveness as a drug prevention scale in secondary students. current articipants were 211 students Johor, Selangor, and Kuala Lumpur, Malaysia. An exploratory factor analysis with principal axis factoring varimax rotation performed for initial analysis. After eigenvalue emerged, data suppressed .30 display loading. value commonalities loading considered frame locate items structure. Furthermore, reliability tested through Cronbach's alpha. result showed that nine factors explaining 58.721% variance. Four 30 eliminated from because they had below threshold. structure follows: seven first factor, four second third two fourth fifth one item sixth seventh eight factors, ninth factor. .748. Meaning internally consistent measuring student`s education.
