Children involved in mutually hostile interactions at home are at risk of experiencing adjustment problems in other everyday life contexts. However, little is known about whether the pattern of mutual hostility at home is reproduced by high-conflict youths in other interpersonal contexts. In this study, we examined whether adolescents involved in mutually hostile interactions with their parents encounter similar mutually hostile interactions in other interpersonal contexts. We used a longitudinal design, following mid-adolescents over 1 year (N = 2,009, 51 % boys, Mage = 14.06, SD = 0.73). The adolescents were 7th and 8th grade students in a mid-sized town in Sweden. The results showed that the youths involved in mutual hostility at home were more likely to be involved in mutual hostility at school and in their free-time. A longitudinal relationship between mutual hostility at home and mutual hostility in other contexts was confirmed. Being involved in mutually hostile interactions at home at Time 1 increased adolescents’ likelihood of getting involved in mutually hostile interactions with peers at school and in free-time at Time 2. Overall, the results point to the important role played by experiencing mutual hostility at home in maladaptive behaviors across everyday settings.
