The present study sought to develop and validate the Masculine Sexual Entitlement Norms (MSEN) Scale. Following scale development best practices, a thorough review of the literature and existing measures was conducted. Next, the construct was operationalized with six hypothesized subscales. Items were developed with input from content experts (N = 9) and focus groups of undergraduate men (N = 9). The initial 90 items (i.e., the MSEN90) were administered to a preliminary sample (N = 281) of undergraduate men. Exploratory factor analysis indicated a five-factor structure (i.e., Prioritizing Sexual Needs of Self, Peer Norms, Sexual Deception, Gender Essentialism, and Minimization of Men's Sexual Behavior). Item analysis yielded a 40-item five-factor survey (MSEN40) that was administered to a second sample (N = 210) of undergraduate men. A confirmatory factor analysis indicated inadequate fit for the 40-item scale; however, fit was improved by reducing scale length to 25 items loading onto one global scale (MSEN25). Internal consistency reliability, construct validity, group differences, and the instrument's ability to predict selfreported sexual violence were explored with this sample. The MSEN25 demonstrated strong correlations with related measures (e.g., Sexual Narcissism Scale, Male Role Norms Inventory-Short Form) and an absence of correlation with unrelated constructs. Additionally, across both samples, the MSEN25 demonstrated adequate internal consistency for the scale overall (α = .90 and .90) and for the five-item subscales (i.e., α's ranged = .71-.82). Future directions and implications for the measure are discussed.
Public Significance StatementDynamics related to sex and masculinity are receiving increasing public and scholarly attention as instances of abuse and violence are more widely acknowledged. The present study identifies an understudied construct-masculine sexual entitlement (MSE)-and provides a framework to target research, clinical, and violence prevention applications of attitudes and behaviors that involve MSE.
