Previous research regarding social work related to sexual health and sexuality shows the importance of competence in this field for social workers and therefore is a need to explore students´ attitudes, knowledge and view on working with sexual health in their future profession. This project aims to psychometrically test the questionnaire Students’ Attitudes towards Addressing Sexual Health (SA-SH) for students in social work. The results show good content validity, construct validity, internal consistency and intra-rater reliability for the SA-SH for students in social work (response rate of 91%, 242 students). The SA-SH can therefore be recommended to be used to measure attitudes, believed competence, and knowledge regarding sexual health among social work students, and to follow up educational interventions.
