The Kirton Adaption-Innovation Inventory (KAI) was evaluated for its factorial composition, internal consistency, and relationship with self-esteem compared with previous studies. Data was from a random sample of adults (n = 214) in a southern city. Results of the factor analysis revealed the scale to have high factorial stability across populations. The scale was found to be highly internally consistent, and a positive correlation with the Rosenberg Self-esteem scale was successfully replicated. These findings provide evidence for the construct validity of the scale.
