Background: Over 70% of children in Germany grow up with at least one other child living in the same household (Statistisches Bundesamt 2014). During childhood, sisters and brothers are companions, teachers, role models but also rivals to each other (Walper et al. 2010).

Method: Participants were recruited using an online survey. Through the course of the online survey participants were asked to invite one of their siblings to take part in the study as well. Both siblings answered the Childhood Trauma Questionnaire and further questions about critical life events, questions regarding their relationship with their siblings and parents during childhood as well as a short measure on their own well-being during the last two weeks.
Results: A total of 4568 participants completed the online questionnaire, in 870 cases both siblings participated in the study. Differences and similarities between childhood maltreatment experience and their implication for the quality of the sibling relationship as well as links to well-being in adulthood are reported.
Discussion: Implications of the results for research and practice as well as limitations of the study are discussed.
