چکیده
-The present study examined the reliability and validity of the 15-item Breskin Rigidity Scale. Two samples of UK adults (n=216; n=277) completed the rigidity scale alongside the Wilson-Patterson Attitude Inventory and the trait measure of the Sandler-Hazari Obsessionality Inventory. Satisfactory reliability coefficients were obtained for the rigidity scale in both samples. A principal components analysis of the 15-item rigidity scale showed that 13 items loaded on the first component and 2 on a second component. These items were removed and the reliability and validity estimates were recalculated. Com~arisons were drawn between the original and amended versions. The amended 13-item scale shows an improved reliability and higher association with other measures of rigidity and rigid character.
