Despite a number of leadership definitions based on a various perspectives in mainstream psychology, the most popular definition of leadership used in sport leadership studies is, "the behavioural process of influencing individuals and groups toward set goals" (Barrow, 1977, p. 232). The Multidimentional Model of Leadership (MML; Chelladurai & Carron, 1978) was developed to explain sport leadership. Although the Leadership Scale for Sport (Chelladurai & Saleh, 1980) has been widely used in sport leadership investigations, several researchers have identified limitations associated with the LSS. Given these shortcomings, Zhang, Jensen, and Mann (1997) developed the Revised Leadership Scale for Sport (RLSS). No independent studies, however, have systematically investigated the psychometric properties of the RLSS. The three interconnected studies in this dissertation were designed to develop the Japanese version of the RLSS (JRLSS) and to examine the psychometric properties of the JRLSS.
