Vulnerability to psychopathology in adolescence: Intolerance of uncertainty as transdiagnostic risk factor

Adolescence is a transition period characterized by several uncertainties and elevated vulnerability to psychopathology. Intolerance of uncertainty (IU) is the tendency to expe-rience negative cognitive, emotional, and behavioural reactions in the face of uncertain situations and it may be a risk factor for the development of psychopathology in this population. IU was originally conceptualized as a disorder-specific vulnerability factor, but its transdiagnostic nature is currently established. The present paper aims to review extant literature focused on the relation-ship between IU and psychopathological outcomes in adolescence.
