The Adaption-Innovation Inventory (AII), originally developed by Kirton (1976), is a widely used self-report instrument for measuring problem-solving styles at work. The present study investigates how scores on the AII are affected by different response styles. Data are collected from a combined sample (N = 738) of students, employees, and entrepreneurs. Using mixture distribution item response theory, we identify individuals with normal and distorted response styles. Additionally, we investigate antecedents and consequences of distorted responses. For antecedents, results indicate influences of cognitive schemata resulting from an individual's professional work context. For consequences, distorted responses show different relationships with occupational outcomes in comparison to normal responses.
