Derivation and validation of the Hamburg Obsession/Compulsion Inventory—Short Form (HOCI—S): First results.

The reliability and validity of the Hamburg Obsession/Compulsion-Short Form (HOCI-S) was examined. Items were selected from the Hamburg Obsession Compulsion Inventory. The item-selection strategy was applied to 4 different groups of subjects: normals (n=200), those with mixed phobia without social phobia (n=121), those with social phobia and social skill deficits (n=211), and those with obsessive-compulsive disorder (OCD; n=125). Selection strategy attempted to detect item difficulty levels across a continuum of obsessive-compulsive behaviors, eliminating age- or gender-correlated items
