Critical Inquiry Flashcards
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?
reliability
What does chi-square do, and what is a big limitation?
establishes that there is a relationship, just not the strength/direction of that relationship
