Subtypes of obsessive-compulsive disorder and their relationship to death anxiety

Abstract

Recent theoretical and empirical research has demonstrated a relationship between death anxiety and obsessive-compulsive disorder (OCD), with a focus on compulsive washing. However, no study has examined whether death anxiety plays an important role across various symptom domains of OCD. The present studies explored the relationship between death anxiety and OCD subtypes across two independent samples of treatment-seeking individuals with this disorder. In Study 1, results from 79 participants demonstrated significant correlations between the Multidimensional Fear of Death Scale and each Vancouver Obsessive Compulsive Inventory (VOCI) subscale. In Study 2, these results were largely replicated using the Collett-Lester Fear of Death Scale in a larger sample of 132 participants. Lastly, results from integrating the samples indicated that the strength of these relationships, although substantial for all types, varied slightly across the subtypes of OCD. Taken together, the findings demonstrate a strong relationship between death anxiety and the differing forms of OCD. Clinical implications include the possibility that fears of death may need to be directly addressed in order to produce long-term symptom amelioration. However, further research is needed to establish the potential causal role of death anxiety across different OCD subtypes.
