Development and validation of the Hookup Motives Questionnaire (HMQ).

Despite the high prevalence rates and growing research on hooking up among college students, no multidimensional inventory exists in the literature to assess motivations for hooking up. In the current study, we report on the development and validation of the Hookup Motives Questionnaire (HMQ), designed to assess the various reasons for hooking up. Exploratory and confirmatory factor analyses were conducted using 2 samples of college students (Campus 1, N = 401; Campus 2, N = 367). Exploratory factor analysis was undertaken to explore the psychometric properties of an initial set of 25 items, and confirmatory factor analysis was conducted to evaluate additional properties of the factor structure. The final factor structure of the HMQ contained 19 items that tapped 5 subscales representing social-sexual, social-relationship, enhancement, coping, and conformity motives. Results demonstrated good internal consistency and discriminant validity for the subscales. Moreover, criterion-related validity was satisfied by showing that HMQ subscales significantly correlated with hookup approval and behavior. Gender differences on the measures were found. The inventory offers considerable potential as a psychometrically sound instrument that may be administered to understand reasons for engaging in potentially risky hookup behaviors and used to inform the design of sexual health programs and interventions targeting young adults.
