Given the main findings of Fiedler’s Contingency Theory (1964-1990s) and Bass’ leadership
theory (1985-2000s), the author hypothesized that there are associations between Leader Member
Exchange (LMX) and leadership style (transactional and transformational) in CISISU(H1); there are
associations between Task Structure (TS) and leadership style (transactional and transformational) in
CISISU (H2); there are associations between Position Power (PP) and leadership style (transactional and
transformational) in CISISU (H3); the three main situational factors (LMX, TS, and PP) affect
transactional leadership style (H4); the three main situational factors (LMX, TS, and PP) affect
transformational leadership style (H5).
