Flashcards in Critical Inquiry Deck (13):
How is the ICF different from the Nagi model?
more consideration of the holistic individual, takes into account environmental factors, and gives us more places to intervene
Should a screening tool be highly sensitive or specific? What are you trying to limit?
Sensitive, trying to limit false negatives.
What are type I and type II errors? How do you control for type I error? How are they related?
type I = incorrect rejection of the null hypo (false positive). Controlled with low P value, high CI value. Type II = failure to reject the null (false negative). If you try to control for one type or the other, the risk of the other increases.
Nagi model: define pathology
disease, disorder, or condition
Nagi: define impairment
pain, sesnsory, weakness, gait
Nagi model: define functional limitation
when impairments result in a restriction of the ability to perform a physical action, task or activity in a typically expected or competent manner
Nagi model: define disability
inability or limitation to engage in community, social, or leisure activities
What is the difference b/w sensitivity and positive predictive value?
sensitivity: probability that a test will indicate disease when there is a truly as disease. PPV: probability that the person with a positive test will truly have the disease.
ANOVA vs t-test
t-test: compares only 2 groups. ANOVA: compares multiple groups
What is the equivalent of 1 SD on normal bell curve? 2? 3?
1 = 68%. 2 = 95%, 3=99%.
Efficacy vs Effectiveness
Efficacy = Internal validty, Effectiveness = external validity
What does Kappa measure?
