The diploma thesis deals with families who face sudden separation of a loved one due to imprisonment. From previous experience the work differs in focusing primarily focused on the family, not prisoners. Theoretical part is devoted to conceptual and legislative definition, the negative effects of imprisonment and the specific needs of the prisoners families as an object of help. Thesis marginally touches on recidivism in the chapter about the family as an entity assist in the reintegration of prisoners and also highlights the potential risks that may family for imprisoned in the process mean. It results from foreign experience, which is traditionally ahead. The empirical part of the qualitative research carried out within of self-help groups of prisoners families provides insight into the specific experiences of families. Its purpose is both to draw attention to this marginalized social group and its needs, as well as outline effective assistance, which would deal with this life situation the best. POTOCKÁ, Veronika.
