Evidence-based Sources

About Evidence

PICOT Questions

Writing a PICOT question will help focus your search for evidence-based sources.

P-Patient population

I-Intervention or Issue of interest

C-Comparison intervention or group

O-Outcome

T-Timeframe

Strong PICOT question: In teenagers, how does cognitive-behavioral skills building compared to yoga affect anxiety after 6 weeks of treatment?

Poorly designed question: What is the best type of intervention to use with teenagers who are anxious?
