Intimate partner violence (IPV) is a major concern across the world, and its prevalence assessment has been a priority in numerous countries. However, data about IPV prevalence in Portugal is scarce and not up-to-date. This study aims to estimate IPV prevalence in Portugal. A community sample of 1392 adults (77.4% female, mean age=34.95 years, SD=12.80) was collected through a web-based survey, between March and June of 2020. Participants completed a socio-demographic questionnaire and the Conflict Tactic Scales-2 (CTS-2). Accounting for all forms of IPV, a past-year prevalence of 64.4% and 64.6% were found, for victimization and perpetration, respectively. Regarding gender or sexual orientation, no significant differences were found in the past-year or the lifetime prevalence, nor concerning frequency. Directionality and dyadic concordance types were analyzed and showed that most violence was bidirectional. Having perpetrated violence in previous intimate relationships was the most influential factor when predicting past-year perpetration or victimization. Other significant predictors were age, being victimized before 15 years old, cohabitation with an intimate partner, and drug use, but the last two were only significant for victimization. Findings support the idea that IPV is a relevant phenomenon, regardless of gender and sexual orientation. It is the first nationwide, gender-inclusive study to do so in Portugal. Studies based on different samples might provide important evidence to prevent hasty conclusions about IPV prevalence and patterns and to guide empirically driven policies.
