A summary of the typical connota-tions of the personality rigidity concept was presented. By means of an item analysis technique, applied to 957 personality inventory items, a 39-item scale for personality rigidity was derived. The criterion used for scale construction was ratings of rigidity by staff assessors from the Institute of Personality Assessment and Research made on a total of 330 Ss. The highest and lowest 25 per cent on rated rigidity were used for the item analysis. Positive cross-validating evidence for two preliminary versions of the scale was presented.
