Knowing what, when, where, who, & why will help to identify appropriate outcome measures
Bottom line.
What psychometric properties are important to consider?

What questions might you have?
Is the tool valid?
Does the tool measure what I want
it to measure?
What questions might you have?
What if the same therapist will not be completing both the initial and discharge
evaluations?
Minimum Detectable Change:
Large enough that the change is not due to error/variance
Is the tool reliable?

What questions might you have?
Cut‐off scores,Normative data
What does the score mean?
What questions might you have?
Minimal Clinically Important Difference:
Change in score signifies a meaningful improvement in
my patient.
How will I know if my treatment
worked?

Bottom line.
Has it been used before in the way I want to use it and will it tell me what I want to know?
Administer tools!
With confidence!

Summary• Define the what, when, where, who, & why
– To help determine the “how” (measure to use)
• Use available resources to examine outcome psychometric properties
• Build your “tool portfolio” one patient (type) at a time
• Collaborate!
– Live, learn, share
