[Study of the relation between transformational leadership of the head nurse and supplementary efforts of nursing personnel].

The present study proposes to show that the ethos of the Head Nursing staff is related to the practice of transformational leadership, and to additional efforts displayed by the treatment staff. Using a sampling of 57 nurses, it was established that transformational leadership presented a positive influence on additional efforts which were superior to that produced by transactional leadership. Contrary to transactional leadership, transformational leadership was shown to exert a positive effect on the ethos of the leader who in turn, had a positive influence on the extra care supplied by the nursing staff.
