• Welcome to the Bem Sexual Role Inventory. This test was developed by Psychologist Sandra Lipsitz Bem in 1971. It measures how well a person fits into their traditional gender role, determining if you are more masucline, feminine, adrogynous, or undifferentiated. For the test, rate yourself on a scale of 1 (never or almost never true) to 7 (always or almost always true). The questions are from the original test but I have tweaked the scoring due to the restrictions on how these tests can be scored.
