The major purpose of this study is to re-test the instruments for leadership style, knowledge sharing behaviour, intrapreneurial orientation and academic leader’s performance due to the differences in research settings and variables structures where these instruments were initially used. As a result, a construct validity test through the factor analysis and reliability test were conducted on 36 respondents who are believed to possess the same characteristics with the main population. The result validates all the instruments for leadership style, knowledge sharing behaviour, intrapreneurship orientation and academic leaders’ performance. The results also indicate that all the instruments for the variables under investigation are reliable.
