This brief self-report measure is designed to help clinicians and school-based practitioners screen interpersonal attitudes related to mistrust and manipulative tendencies in children and adolescents. The Children's Mach Scale consists of 20 items and typically takes about 4 minutes to complete.
Items are phrased to be developmentally appropriate, supporting interpretation of response patterns reflecting skepticism about others’ intentions and a preference for controlling social situations. The Children's Mach Scale is intended for use as part of a broader, multi-method assessment and should be interpreted in light of age, context, and collateral information.
