Comparison of leadership theories
| Criterion | Trait | Behavioural | Contingency | Transformational / transactional |
|---|---|---|---|---|
| Central question | What traits do good leaders have? | What do good leaders do? | Which behaviour works in which situation? | Does the leader inspire followers, or trade rewards for results? |
| Strength | Measurable; plenty of data | Tends to explain more of leadership effectiveness than traits do | Recognises context: when a crisis is familiar directive fits, when it is unfamiliar participative fits | Transformational correlates 0.44 with leadership effectiveness, contingent reward 0.39 |
| Limit | Depends on context; explains less than behaviour | The same behaviour can suit one situation and fail in another | Tests of situational leadership theory give only limited support | Overlaps heavily with contingent reward (0.80), so hard to separate |
Pitfalls
Pitfall
Treating the streams as successive, each replacing the last. DeRue et al. (2011) found that traits and behaviours together explain at least 31% of the variance in leadership effectiveness, behaviours explain more, and behaviours mediate the link from traits to effectiveness.
