The purpose of this study is to investigate preschool personnel experiences concerning their obligation to report existing and suspicions of child maltreatment. This is a qualitative study based on in-depth interviews that can provide a good understanding of the subject and of the informants’ views. The theoretical starting points we used were the communication theory, Kelly’s personality theory and the role theory. We carried out eight interviews with pre-school personnel who work in four different counties in Sweden. The interviews lasted between 45 to 60 minutes. The result from our study shows that the pre-school personnel have a positive view upon their obligation to report child maltreatment. In contradiction to this, the result also shows that there is a fear and concern about making a report. The main reasons for not reporting, is the relationship with the preschool children’s parents, lack of knowledge to identify the children who suffer the abuse, previous bad experiences from the social services and poor feedback from the social services.
