Abstract
Research Aims/Questions: Traditionally, hoarding symptoms were coded under obsessive compulsive disorder (OCD), however, in DSM-5 hoarding symptoms are classified into a new independent diagnosis, hoarding disorder (HD). This change will likely have a considerable impact on the self-report scales that are commonly used to measure symptoms of OCD. Therefore the aim of this study was to evaluate the psychometric properties of one of the most commonly used selfreport scales, the Obsessive Compulsive Inventory – Revised (OCI-R), taking into consideration the new DSM-5 structure.
Methodology: This study evaluated the psychometric properties of the OCI-R, in a sample of 474 individuals with either OCD (n=118), HD (n=201) or no current or past psychiatric disorders (healthy control) (n=155). For the purposes of this study the OCI-R was divided into two scales; the OCI-OCD (measuring the 5 dimensions of OCD) and the OCI-HD (measuring the hoarding dimension). The reliability and validity of each of these measures were assessed and a clinical cut off point for each measure was obtained.
Conclusion: The reliability and validity of both measures was good. The receiver operating characteristic analyses demonstrated that a clinical cut off of 6 on the OCI-HD and 12 on the OCI-OCD provided the best balance between sensitivity and specificity. The results of this study highlight the potential of the OCI-R as a screening measure for individuals with OCD and HD and demonstrate the utility of separate clinical cut offs for assessing likely diagnosis of both HD and OCD.
