Improve the selection of your health measure instrument with COnsensus-based Standards for the selection of health Measurement Instruments’ (COSMIN) critical appraisal tool (a checklist) containing standards for evaluating the methodological quality of studies on the measurement properties of health measurement instruments.
How to Select a HealthMeasure
There are many factors to consider in selecting a HealthMeasure for a specific purpose.
- Intended use of the data:
- Measures used for screening multiple symptoms or conditions need to be brief to reduce respondent burden. However, short measures are typically less precise than longer measures unless computer adaptive tests (CATs) are used.
- Measures used to diagnose a condition, or risk for condition, (e.g., depression), should be longer to ensure the condition is measured reliably. Longer questionnaires or CAT–based assessment are a good options.
- Measures that monitor a person’s health over time require more precision than screening measures. This will allow a clinician to evaluate how the patient’s health is changing based on the nature of the disease or treatment initiation. CAT-based assessments are good options as they can accurately capture change over time.
- Measures can be used as an indicator of quality of healthcare. Measures of the performance of healthcare providers or healthcare delivery organizations are being designed to evaluate change in health status over time in individuals (e.g., pre- to post-hip surgery physical functioning). Longer questionnaires (or CAT) are recommended.
- Patient population:
- The health condition or disease of the population will inform the type of outcomes that need to be assessed. For example, physical functioning is critical for arthritis patients and the impact of asthma is important for children with asthma.
- As older populations may have multiple chronic conditions, PROMIS® profiles may be of interest as they capture a range of outcomes including physical functioning, pain severity, pain interference, fatigue, sleep disturbance, depression, anxiety, and ability to participate in social roles and activities.

Review our detailed Guide on Selecting a HealthMeasure. It addresses:
- Identification of goals and/or aims of the assessment
- When to consider performance-based measures
- Deciding between global and specific outcomes
- Determining if your measure is for a primary, secondary, or exploratory endpoint
- Differences between universal outcomes and disease/condition-specific outcomes
- Differences between fixed length short forms and computer adaptive tests
- Determining needed reliability, precision, and length of a measure
- Appropriateness for target population
The International Society for Quality of Life Research and the National Cancer Institute hosted a webinar on selecting the appropriate outcome measure. Factors to consider include:
- Conceptual and measurement model
- Low respondent and administrative burden
- Alternate forms
- Cultural and language adaptations
How to Select a Physical Function Measure
- PROMIS, Neuro-QoL, ASCQ-Me, and NIH Toolbox all include measures of physical function.
