On Wakefield's harmful dysfunction analysis of mental disorder

Wakefield's harmful dysfunction analysis of mental disorder is among the mo st rigorous and thoughtful attempts to address serious conceptual problems that beset the foundations of abnormal psychology. Accord ing to Wakefield, disorder is a hybrid concept comprising a factual component specifying der angement in a naturally-selected function, and a value component specifying the resultant harm. It is unclear, however, whether an evolutionary interp retation of dysfunction is either feasible or necessary: a nonhistorical ca usal role analysis of psychological function may enable ascription of disor der (assuming resultant harm), More over, the dysfunction component itself appears hybrid, comprising both a factual assertion about the state of a me chanism and a normative assertion implying that the mechanism is not functi oning as it ought be.
