Personal construct theory and the argument against mental illness

An attempt is made to integrate Thomas Szasz's 0974) theory of personal conduct and George Kelly's (1955) theory of personal constructs (PCT). It is argued that PCT provides an alternative to the void left behind by Szasz's negation of mental illness. Because PCT is concerned with psychological, rather than physiological, constructions of problems in living, it is not compatible with the biological model associated with Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnostic categories. Rather, it is in keeping with the views of Szasz. Kelly's and Szasz's writings are used to support this view. Kelly's transitive diagnosis approach to “mental illness”, wherein diagnosis and therapy are construed as process oriented as opposed to category driven, is described as an alternative to the biological model. A contextualist approach (Sarbin & Mancuso, 1980) is also discussed. These approaches not only empower clients and allow them to assert responsibility and control over their lives, but also provide an alternative system to the one rejected by Szasz.
