The main intention of this research is to examine the content validity of Marine
Engineer Personality Inventory or PERJURA for student candidates of Diploma in
Marine Engineering course at Malaysian Polytechnics by using Content Validity Ratio
(CVR). The assessment was conducted through the evaluation among 14 subject
matter experts (SME) selected via judgment sampling. Seven professional university
experts involved with the expertise in psychology, psychometric, educational
measurement and linguistics. The field experts specializing in particular fields of study
consisted of seven practitioners who worked in the polytechnics field and maritime
industry. The instrument involved 288 items with six main constructs. The results of
the research show that the instrument has a good content validity and proved that
PERJURA has great potential to be promoted as a good measurement instrument of
personality screening for Marine Engineering student selection process. It is
recommended to apply more sophisticated statistical analysis, such as the Item
Response Theory (IRT) model for elaborating on quality items.
