Salkovskis' cognitive model of obsessive compulsive disorder (OCD, 1985) has led to a wealth of research which has identified a number of cognitive vulnerabilities thought to be characteristic of the disorder. Schemata related to responsibility, guilt, faulty meta-cognitive beliefs, thought action fusion and the appropriateness of neutralisation have been associated with OCD symptomatology. However, the majority of research has used non-clinical subjects, with varying criteria and methodology, leading to problems in interpreting the results. More recent work (Sookman et al, 1994) has attempted to develop a multidimensional model of OCD. The emphasis is on addressing early attachment experience to examine the possible aetiology of core schemata. Subsequent research has not reflected the need to develop this comprehensive approach to our understanding of OCD: cognitive theorists have continued to examine cognitive schemata in isolation; separate research has addressed personality factors such as perfectionism; a third vein has examined OCD patients' reports of parenting. In the current paper, 20 subjects with a diagnosis of OCD and an anxious control group of 20 subjects are compared on a number of measures, aimed at examining i) OCD related schemata (Inventory of Beliefs Related to Obsessions, Freeston et al 1993), ii) experience of parenting (Parental Bonding Instrument, Parker et al, 1979) and iii) the fundamental personality dimensions of sociotropy and autonomy (Personal Style Inventory, Robins et at, 1994). The paper compares scores on these measures between experimental and control groups to examine OCD specificity and confirm the unique role of particular schemata in a clinical OCD group. The relationship between early experience, cognitive vulnerability and OCD symptomatology is examined in an attempt to incorporate these factors into a comprehensive account of OCD which links early experience to OCD through the mediating influence of dysfunctional assumptions and cognitive vulnerabilities.
