Abstract

The aim of this study is to develop and acquire content validity and reliability for Extrovert and Introvert Personality Inventory (IPEI). IPEI is developed based on the personality theory by Jung (1954). IPEI has 30 items comprising of two subscales. The first is an extrovert personality subscale (15 positive items) while the second is introvert personality subscale (15 positive items). In determining the content validity of the IPEI, it was evaluated by an expert panel of 11 people consisting of academicians and education practitioners; psychology and counseling at the Higher Education Institute (HEI) and the school. Reliability analysis of IPEI was tested on 40 respondents consisting of students at a university in the state of Perak, Malaysia. IPEI has a good overall content validity of 87.8 percent with cumulative value equal to 0.88. Content validity based on extrovert subscale were 88.6 per cent, while introvert subscale is 87.0 percent. This indicates that the IPEI have high expert content validity. The overall reliability analysis of IPEI is acceptable at .60. Analysis of the reliability of extrovert subscales show satisfactory results of .73 while introverts subscales was .80. As such, the study succeeded in producing IPEI with a good validity and reliability and useful to use for determining whether an individual personality is extrovert or introvert.
