Despite scholarly interest in changes in masculinity, no study to date offers quantitative measures of nontraditional masculinity ideologies. We identify common denominators of ''new masculinity'' (NM) ideology rooted in therapeutic discourse, which includes themes of authenticity and holistic self-awareness. A theoretical construct of NM was formalized from in-depth interviews and operationalized as the NM Inventory (NMI). The NMI was tested for structural and external validity in two quantitative samples of Israeli men. The inventory demonstrated discriminant validity with traditional and consumer masculinity ideologies, converged with selflabeling as feminist, and was uniquely predicted by lower levels of modern sexism. This suggests stronger associations between NM and feminist attitudes than previously argued. Lay responses confounded between self-labeling as new man and as metrosexual, echoing ambiguities in public rhetoric of NM. As a unique measure of nontraditional masculinity, the NMI can spur more systematic research into variable outcomes of contemporary understandings of masculinity.
