Outcome Measures

What Are Outcome Measures?

Outcome measures are all the possible measurements of results that may stem from exposure to a causal factor, or from preventive or therapeutic interventions.

All identified measurements of changes in health status arising as a consequence of the handling of a health problem

Types of Outcome Measures

Subjective:

  • Self-perceived pain
  • Physical disability
  • Psychological well-being
  • Depression
  • Mental status (dementia)

Objective:

  • X-ray
  • MRI
  • Body mass index
  • Weight
  • Blood pressure
  • White blood cell count

Qualitative

  • Anything that can be described in words (usually in quotes)
  • Examples
  • – “I have not been able to sleep through the night in years!”
  • – “I didn’t know that back pain was also related to my fatigue.”

Quantitative

  • Anything that can be described in numbers (subjective or objective)
  • Examples
  • – Lab results
  • – Height/weight
  • – Pain levels on VAS
  • – Quality of life on SF36

Which Outcome Measures should be used?

  • Look at which measures are consistently used in the literature
  • Read articles on new outcome measures
  • – Reliability
  • – Validity

Validity and Reliability of Outcome Measures

  • Need to do conduct literature search to determine the reliability and validity of the outcome measures used.
  • If you find that instruments used are not reliable or valid (or not enough literature) then that needs to be commented on in the discussion section.
