Physical abuse and neglecting of children can be physically observed which facilitates the study and suppression of this type of violence against children. Mental abuse or neglect that children can experience within the family is a more 'elusive' concept because it doesn't leave clear material evidence and poses a greater challenge in doing research and in daily practice. Although it is almost always accompanied by other forms of abuse or neglect, it can occur independently. In this area of study defining, recognizing and measuring a problem poses great difficulties. Therefore it is very hard to determine the extent of this problem in general population, while the high quality intervention is often missing. Sexual abuse is also not so easy to determine because the victims frequently hide what they have experienced in order to avoid being exposed to embarrassment, shame, mistrust, derision or labelling. However, increasing awareness from expert of this form of abuse within the family brings forth better results in sanctioning this type of violence. Children can suffer from neglect in various areas and it can greatly influence their psycho-physical and intellectual development. This thesis will show different forms of violence within the family and psychological effects brought by particular forms of violence.
