Linking obsessional beliefs to OCD symptoms in older and younger adults

There are many open questions about the phenomenology of obsessive-compulsive disorder (OCD) in the elderly, and theories about the development of OCD have rarely been applied to older populations. The current study uses structural equation models to evaluate the relationship between obsessional beliefs and OCD symptoms across young and older adult age groups in a large community sample (aged 18–93; N=335N=335), and to examine whether subjective concerns about cognitive decline partially mediate this relationship. Results support partial mediation, and follow-up analyses suggest that the pattern of relationships among subjective cognitive concerns, obsessional beliefs and OCD symptoms is invariant for younger and older adults, but older adults report relatively greater levels of subjective cognitive concerns.
