Flashcards
Health Research Areas
Health Research Areas
Health research can focus on improving population health, predicting disease progression, and exploring community-based interventions for disease prevention.
Inclusion/Exclusion Criteria
Inclusion/Exclusion Criteria
Study criteria must clearly define who is and is not included in a research study.
Sample and Size
Sample and Size
Sample selection and size are important for a research study; both should be appropriate for the research questions.
Study Notes
Health Research
- Health research can include various areas such as:
- Epidemiology: study of distribution and determinants of health-related events
- Clinical research: development and testing of interventions
- Health services research: evaluation of healthcare systems and services
- Behavioral and social sciences research: study of social and behavioral factors influencing health
Sample and Sample Size
- An appropriate sample should:
- Represent the target population
- Be of adequate size to detect statistically significant differences
- Consider factors such as sampling method, sample size calculation, and selection bias
- Sample size should be:
- Sufficiently large to provide reliable results
- Calculated based on factors such as effect size, alpha level, and power
- Justified in the study protocol
Inclusion and Exclusion Criteria
- Defining inclusion and exclusion criteria in a study protocol:
- Ensures that the study population is well-defined
- Helps to minimize confounding variables and sampling bias
- Facilitates the generalizability of study results
- Correct statements regarding inclusion and exclusion criteria include:
- Inclusion criteria define the characteristics required for participants to be included in the study
- Exclusion criteria define the characteristics that exclude participants from the study
- Inclusion and exclusion criteria should be specified clearly in the study protocol
