Dogmatism Scale

The Dogmatism Scale is a psychological measurement instrument developed by Milton Rokeach to assess individual differences in dogmatism (rigid, closed-minded belief systems). It has been criticized for weak internal consistency, questionable construct validity, and issues with balanced item development and shortened versions failing to capture the full construct.
