Assessing Content Validity of IKBAR among Field Experts in Polytechnics
Universiti Sains Malaysia
ABSTRACT
This study aims to examine the content validity of measurement instruments of the Adversity Quotient or IKBAR for polytechnic students. The analysis used the Content Validity Ratio (CVR) based on the Lawshe Validity Model (1975). This study was conducted through the evaluation of written and online questionnaires on 28 field experts selected via purposive sampling. The experts specializing in particular fields who worked in polytechnics area as directors, lecturers, psychologists and student affairs officers. The validity involved 220 items with four main constructs such as Control, Ownership, Reach and Endurance. The CVR’s critical value that must be adhered to is 0.370 (N = 28) for the purpose of refining items. The results of the study shows that the instrument has good content validity of the candidates in the research (N = 28, CVRcritical = 0.370, CVRall = 21 items refined). The results have proved the IKBAR instrument has great potential to be promoted as a measuring instrument for psychometric adversity quotient for polytechnic students. It is recommended that further research be carried out using more sophisticated statistical analysis, for elaborating on quality items.
