Abstract
The present research involved an item analysis of the Wesley Rigidity Inventory (1953) to determine its unidimensionality and the effect of age and intelligence. Factor analysis revealed orthogonally-related factors: rigidity in intellectual thinking, liking for established routine which was highly loaded with the factor of age, and a factor of appreciation of methodical behavior and details.
