| Summary: | The objective of this research is to assess the validity and reliability of the general mental
ability instrument that was developed based on Western norms. The instrument comprise 153
items obtained from the International Cognitive Ability Resources (ICAR) categorised into
three dimension (3D) rotation, abstract reasoning, figural analogies, letter-number series,
matrix reasoning and verbal reasoning. Forty-five (45) masters-programme students from the
Human and Social Science Faculty at a local university undertook the 1-hour test. Utilising
the Winsteps software, the Rasch meaurement analysis comprising summary statistics,
unidimensionality and item-person measures were used to test the validity and reliability of
the ICAR. The research findings indicated that the ICAR has good psychometric properties
that is acceptable as a mesure of general mental ability. Nonetheless, the findings also
indicated that the ICAR was difficult relative to the respondents’ ability. As such,
improvements and selection of appropriate item-difficulty level are required to portray a more
accurate level of the general mental ability in the local context. |
