“…However, a review of LMX studies published in the last 10 years reveals two different theoretical conceptualizations of LMX: the popularity of LMX research grew, so did the number of items. For example, Graen and Cashman (1975) and Liden and Graen (1980) measured vertical exchange with a four-item scale; Graen, Liden, and Hoel (1982) employed a five-item scale to measure LMX; Schriesheim, Neider, Scandura, and Tepper (1992) developed a six-item LMX scale; Graen, Novak, and Sommerkamp (1982) proposed a seven-item LMX scale; Kozlowski and Doherty (1989) used an eight-item information exchange scale; Bhal and Ansari (1996) employed a 10-item quality interaction scale; Liden and Maslyn (1998) developed an 11-and, subsequently, a 12-item multidimensional LMX scale. Others have used a 14-item vertical exchange scale (Wakabayashi, Graen, & Uhl-Bien, 1990;Uhl-Bien & Maslyn, 2003), a 17-item LMX scale (Deluga & Perry, 1994), and even a 40-item Leader Behavior Description Questionnaire (Graen, Dansereau, & Minami, 1972).…”
