The triple vulnerability theory
The triple vulnerability theory in the etiology of anxiety and its associated disorders of David Barlow was formulated in the year 1988 and updated in the year 2000 and 2002. Barlow and his collogues organized the triple vulnerability model f neuroticism in 1988. It involved a strong biological constituent and general psychological elements (Barlow et al., 2013). The biological constituent is based on the level of hereditability while the psychological elements are referred to as the disruptive early experiences that may predispose someone to a temperament, trauma, or parenting style that leads to a notion that the world is difficult, and usually an uncontrollable place to live in. The third element of this model is of a specific component, or a specific kind of anxiety-like obsessive-compulsiveness, panic, or a particular phobia. In the 1990s, Barlow and his colleague Timothy Brown carried out a closer examination of the role of neuroticism in the mood and anxiety disorders found in parents. The findings were adopted in 2000 and later re-examined in 2002 (Gallagher, Bentley and Barlow, 2014).
