Abstract: The aim of this study was to determine the prevalence and evaluation of the adjudicated incest cases in the heavy penal court in a province of western Turkey. The court files of 65 incest cases during a 10-year period between 1999 and 2008 were explored. When compared to those who lived in cities, the cases who lived in rural areas, such as villages or towns, had been exposed to penetration more frequently (94.3% and 70.0%, respectively, p < 0.01). For the cases where the victim and perpetrator lived in the same house, the accused were generally members of the nuclear family (p < 0.001). When compared to those who had not been exposed to penetration, most of those who had been exposed to it were determined to apply later (after 10 days) to judicial institutions (77.8%, p < 0.01). The education and awareness of persons, such as teachers and physicians, who may confront incestuous relationships rather frequently are very important in the protection of children and in their adaptation to society.
