Intimate partner violence (IPV) is a problem of global proportions that affect men and women worldwide. It is a problem that occurs in all stages of life where we have intimate partners, starting in adolescence. Previous research show that the prevalence of IPV in adolescence is high, around 30% in most parts of Europe and North America. In Scandinavia the levels are a bit lower with previous research showing rates from approximately 10 to 20%, although the research in the Scandinavian context is scarce. The effects of morality on IPV perpetration is even less studied, with previous research showing that there is a significant correlation between the personal morality regarding IPV (IPV morality) and IPV perpetration. The aim of the present study is to use a Situational action theory perspective to study the prevalence of physical IPV and to investigate if there are significant associations between IPV perpetration, levels of IPV morality and levels of partner conflict in a sample of Swedish adolescence. The study is cross-sectional and based on self-reported data collected in the Malmö Individual Neighborhood Development Study (MINDS) during 2014 when the participants were between 18-19 years old. The results showed an IPV prevalence around 4-7% and that there were significant associations between morality and IPV perpetration and between IPV morality and IPV perpetration. The association between partner conflict and IPV perpetration was not significant. Also, the results revealed that levels of IPV morality may shift depending on the situation and that girls seem to have lower IPV morality than boys. Furthermore, the results showed that IPV perpetration is bidirectional with boys and girls being as likely to commit acts of IPV.
