ABSTRACT
INTRODUCTION: The majority of patients with delusional infestation (DI) seek help from dermatologists as they consider their condition to be of cutaneous origin and deny referral to psychiatrists, with the prevalence of the condition arising. The objectives of our study were: (i) to assess whether there is a fixed delusional ideation in patients with DI, (ii) to assess the efficacy of managing such patients with combined dermatological and psychiatric treatment and (iii) to test any correlation between BABS scores and other variables. METHODS: All consecutive newly diagnosed patients with DI, from January 2014 to January 2015, seen in our specialist psychodermatology clinic were enrolled in our prospective observational study. Brown Assessment of Beliefs Scale (BABS) was used to assess the intensity of delusion. Correlation between BABS and other variables was also assessed. RESULTS: Forty-three patients were enrolled. There was a range of BABS scores pre- and post-treatment, indicative of the presence of a range of delusional ideation. A significant reduction in the BABS scores was noted post-treatment from 16.10 ± 5.53 to 11.66 ± 8.26 (p < .002). CONCLUSION: This is the first study to objectively demonstrate that delusional belief in patients with DI is not a binary phenomenon and to demonstrate an efficacious response to a combined multidisciplinary psychodermatological approach.
