Central aspects of intra-familiar violence and of their causes are discussed. The first results of the study "Handeln statt Misshandeln" (HSM, Action against Violence) are presented. Data were collected in Bonn, Germany, by the means of a postal questionnaire. Approximately 10 percent of old people reported experiences of violence in their families during the past five years. Most often mental violence and financial deceit were mentioned. Experiences of violence mainly caused psychological and emotional problems. If at all, victims searched for support in their immediate social network. Persons who were married or of bad physical health had often experiences of violence. Significant difference between victims and non-victims were detected for experiences of violence, the victims' subjective well-being, the quality of the families' external relations and the victims' socio-economic status.
