Abstract

The Ummatic Personality Inventory (UPI)© was devised within a specific framework. It intends to be an
assessment tool for self-introspection (muhasabah) and self-improvement (islah). Central to this idea is the
concept that one would be able to identify the area where improvements could be made as far as one’s
personality as a Muslim is concerned. This research was conducted at two universities. The sample size was 588.
The statistical method, Principal Component Analysis (PCA), was used. PCA was used to identify the underlying
dimensions for each construct of the instrument. The results provide evidence that the developed instrument
possesses sound psychometric properties. The reliability test indicated that the instrument was reliable, given that
the overall reliability value of Cronbach’s Alpha was .963. The findings revealed that with the use of PCA, the
Ibadah (worship) construct produced 5 significant factors, the Amanah (trust) construct generated 5 factors and
the Ilm(knowledge) construct produced 2 factors. In conclusion, this study produced a prototype of the Ummatic
Personality Inventory that possesses sound psychometric properties and contributes to the development of a
novel psychological instrument from the Islamic perspective.
