Abstract:
The purposes of this research were to study the predictions of job satisfaction and affective commitment by assessing transformational leadership as mediated by liking of leader. The instruments used were Multifactor Leadership Questionnaire (Bass, 1985), Job Descriptive Index (Smith, Kendall, & Hulin, 1985), Affective commitment questionnaire (Allen & Meyer, 1990), and liking of leader questionnaire (Brown & Keeping, 2005). The participants (N = 385) were males and females who have worked in the Operation Department of Electricity Generating Authority of Thailand, Results are as follows: 1. Transformational leadership can significantly predict job satisfaction (p < .01) and affective commitment (p < .05). 2. Transactional leadership can significantly predict job satisfaction (p < .05) and affective commitment (p < .01). 3. Laissez-faire leadership can significantly predict job satisfaction (p < .01). 4. Liking of leader significantly mediates the relationships between transformational leadership and job satisfaction (p <.001) and between transformational leadership and affective commitment (p < .001). 5. Liking of leader significantly mediates the relationships between transformational leadership, which consists of 4 factors and contingent reward, and job satisfaction (p < .001). 6. Liking of leader significantly mediates the relationships between transformational leadership, which consists of 4 factors and contingent reward, and affective commitment (p < .001). 7. Contingent reward has significant positive correlations with charismatic leadership, inspirational leadership, and individual consideration subscales of transformational leadership (p < .01). 8. Laissez-faire leadership has significant negative correlations with charismatic leadership, inspirational leadership, individual consideration, intellectual stimulation, contingent reward, and management by exception in active form (p < .01). 9. Management by exception in passive form has significant negative correlations with charismatic leadership, and intellectual stimulation (p < .01)
