I want to assess temperament dimensions in patients with intellectual disabilities. A common instrument to assess this is the Temperament and Coping Inventory, but to my knowledge the TCI is not validated nor intended for ID samples. Other instruments that I found were the Child Behavior Questionnaire, and the Emotionality, Activity, Sociability (EAS) Temperament Survey, but these apply more to children than to adults (i.e.., they seem too childish). Does anyone have any suggestions? It's for diagnostic (and ultimately research) purposes and adult patients.
