Flashcards in Evidence-Based Practice Deck (7)
Quantitative vs. Qualitative studies
Quantitative = number-based, measurable (ie: survey data)
Qualitative = collecting of words (ie: interview feedback) more than numeric data
Single-Hierarchy Evidence Model
Goes from Level I (highest validity) to Level V (lowest validity).
Level I = Ideal; systematic reviews, *randomized* controlled trials, meta-analyses.
Level V = Least ideal; narrative reviews, descriptive case reports (ie: therapist describes one client case)
Review of high-quality studies on a particular research question. Means multiple studies were used. *Higher validity type of research (Level I)!
Like a systematic review, but uses statistical techniques to combine results of eligible studies. *More statistics-involved than systematic review.* Also a higher validity (Level I) research.
Randomized Controlled Trial (RCT)
Group participation is randomly done, outcomes are compared to outcomes of a control group. *More people + more randomized = best validity scenario!
Higher Level Evidence means:
• Less likely biased
• May be more generalizable
• More trustworthy
• More scientifically rigorous
• Outcome attributable to the intervention studied
