ANALYSIS OF THE SHORT VERSION OF THE HAMB URG OBSESSIVE-COMPULSIVE INVENTORY (HZI-K)

The Hamburg Obsessive-Compulsive Inventory - short version (Hamburger Zwangsinventar - Kurzform, HZI-K) is a behavioural oriented questionna ire for measuring of obsessive-compulsive symptoms of different degree s of severity. The 72 items are divided into six subscales: A, 'checki ng' ;B, 'washing, cleaning'; C, 'tidying' D, 'counting, touching, spea king'; E, 'thinking of words and ideas'; F, 'thoughts of harming onese lf or others'. The HZI-K was evaluated in a sample of n = 77 healthy a dults (35 men, 42 women). The postulated subdivision of each subscale into two parts of different degrees of severity could be verified, In accordance with previous results, a principal components analysis of t he subscales yielded two orthogonal dimensions: I. 'obsessions (subsca les D, E, and F) and II. 'compulsions' (subscales A, B, and C); subsca le A is also highly correlated to the first component. A more conseque nt consideration of factor analytical results for the formation of the HZI-K subscales is desirable.
