Researchers have raised questions concerning the validity of masculinity-related measures in relation to existing masculine gender role theory. The current study adds to the existing knowledge concerning masculine gender role-related measures by examining 8 masculinityrelated instruments representing 3 broad constructs: masculinity ideology, masculine role conflict, and gender role ideology. Four distinct dimensions, accounting for 67% of the total variance, were revealed in a sample of 162 college men. Results of multiple regression analyses predicting sociosexuality from participants' scores on the 4 faclorially derived masculinity dimensions offered some preliminary convergent validity evidence for the 4 dimensions. Theoretical implications of the findings are discussed, and directions for future masculinity research are offered. Following in the footsteps of feminist research on women, psychological researchers have taken an interest in the study of masculinity and men's gender roles, culminating in the recent formation of the American Psychological Association's Division 51 (Society for the Psychological Study of Men and Masculinity). Whereas early research attempted to identify masculine personality traits and their correlates, more recent research efforts have centered on dimensions of masculine gender role socialization, including attitudes about and internalization of societal prescriptions for masculinity. Within this paradigm, a variety of theories and conceptual schemes have been reviewed extensively (see Good, Wallace, & Borst, 1994;Levant, 1996), as have operational!zations of masculine gender role variables (Thompson, Pleck, & Ferrera, 1992). However, concerns have been raised (e.g., Betz, 1995) regarding the relations among com-
