The article is devoted to the description of scientific research and theoretical generalization of modern ideas about the influence of psychological factors on personal changes in parents raising children with disabilities. The study outlines the urgency of this problem, as the number of such families is constantly growing and the fact of birth of a child with mental and physical disabilities can become a trauma for parents, which manifests itself in the form of despair, anger, irritability and more. The study of the personal characteristics of parents raising children with disabilities is important for the development of effective methods and programs of psychological support for such families. Common features of parents of children with disabilities are sensitivity, hypersocialization and protective behavior, they are characterized by feelings of isolation, depression, weakness and the need for compassion of others, and the main psychological reactions to a child with developmental disabilities are shock, denial, aggression, depression and acceptance. Parents with high levels of subjective stress have fewer adaptive resources to their child's special needs. In general, parents of children with disabilities are divided into neurotic, authoritarian and psychosomatic types (according to V. Tkachova) and schizophrenic, epileptoid, steroid and cycloid psychotypes (according to I. Ryzhenko).
The concept of experiencing heavy loss is highlighted by E. Kubler-Ross, OV Gnezdylov, K. Lucas and the constitutional-continuum concept of IV Boev and OO Akhverdov. In general, personality-typological constitutional variability determines the transformation of personality in the ranges of psychological norm-accentuation-borderline abnormal personality (MAO) – pathological mental constitution (psychopathy). The severity of variational personal variability, which is defined constitutionally, is responsible for the adaptability, tolerance and compensatory capabilities of the individual to pathogenic stresses, ie the result of the refraction of external factors through the internal (constitutional) content. Determining the level of constitutional determinism of personality-typological manifestations in parents contributes to a more accurate prediction of their reaction in extreme conditions.
