The theory of positive disintegration (TPD) by Kazimierz Dąbrowski is a theory of personality development.
Unlike some other theories of development such as Erikson’s stages of psychosocial development, it is not assumed that even a majority of people progress through all levels. TPD is not a theory of stages, and levels do not correlate with age.
Unlike mainstream psychology, Dąbrowski’s theoretical framework views psychological tension and anxiety as necessary for growth. These “disintegrative” processes are therefore seen as “positive”, whereas people who fail to go through positive disintegration may remain for their entire lives in a state of “primary integration”, lacking true individuality. Advancing into disintegration and into the higher levels of development is predicated on having developmental potential, including overexcitabilities, above-average reactions to stimuli.
