Document Summary

Study design is entirely dependent on the goal of the study. Tertiary analysis: writing a review/ meta-analysis article. Two types of studies: observational (p 42, 46, 50, 59-60, experimental. Only a randomized experiment is the golden standard of causality. Cross-sectional: exposure and outcome at same time. Case-control: have people with outcome, want to look at why exposure happened. Cohort: direction of exposure goes to outcome: experimental. Randomized control trial (rct): one (or more) active intervention group(s), randomly assigned and one control group: often blinded to reduce bias. Quasi-experimental: non-random assignment to groups: may not have control group. Natural experiment: interventions not manipulated by researcher. Qualitative studies: phenomenology: examines how participants understand/interpret life experiences. #1: grounded theory: uses observations to develop theories about human behavior.
