Differences between NIH Toolbox® Emotion Measures

Computer Adaptive Tests (CATs) versus Fixed Forms

NIH Toolbox Emotion measures include computer adaptive tests (CATs) and fixed forms (FF).

  • CATs
    • Tailored selection of items for each respondent
    • Requires administration technology
    • High measurement precision across a wide range of symptom/function severity
  • Fixed Forms
    • All respondents answer all questions
    • No special administration technology needed
    • Degree of measurement precision varies
