Norms for College Undergraduates for the Bem Sex-Role Inventory and the Wiggins Interpersonal Behavior Circle

Norms based on large random samples of introductory psychology college students are presented for the Bem Sex-Role Inventory (N = 1,133) and the Wiggins Interpersonal Behavior Circle (N = 564). The use of normative data, as compared with raw data or data standardized separately within studies, should result in more precise and meaningful measurement of subjects' locations on sex-role dimensions (i.e., instrumentality and expressiveness) by future researchers using these instruments, although norms should be updated to reflect future research results. Conventional definitions of moderately extreme and statistically extreme scores are presented for these instruments based on these norms, encouraging standardization of sample characteristics of future studies.
