ABSTRACT: This study aimed to investigated the psychometric properties
of the High Potential Traits Inventory (HPTI), particularly reliability, structure
as well as convergent and predictive validity. The previously established six-factor
structure (MacRae & Furnham, 2014) was tested through structural equation modelling (SEM), along with subscale
reliabilities measured by Cronbach’s α.
All subscales had high reliability. Convergent validity with the NEO-PI-R was also
tested. All HPTI and NEO-PI-R personality factors were regressed on a measure of
subjective success to determine predictive validity. Model fit was sufficient for
early scale validation, but suggested more work needs
to be done. HPTI subscales were highly correlated with subjective success, and significantly
better predictors of subjective success when all personality factors were regressed
on a measure of subjective success. Limitations, implications, and the need for
further work are discussed.
