An investigation of the psychometric properties of the Maree Career Matrix

The purpose of this study was to investigate the reliability and structural validity of the Maree Career Matrix when used to measure the vocational interests of adults. Reliability of the 19 Maree Career Matrix interest categories were investigated using Cronbach’s alpha and McDonald’s omega total and the structural validity of these 19 interest categories was examined using principal components analysis. Results indicated mostly satisfactory reliability of the 19 interest categories when used for discussion of interest profiles and that the 19 interest categories formed approximate circular ordering consistent with Holland’s circumplex model of vocational personality types. These results provide initial support for the reliability and structural validity of the Maree Career Matrix when used to measure the vocational interests of adults. Implications for theory and practice are discussed
