  1. Research Methodology Directed learning

  2. Research Process • Research process consist series of action that are systematic and organize into step. • The process include : • Problem selection • Literature review • Finding research gap • Formulation research objective and hypothesis • Selection of appropriate study design • Selection of variables and tools • Sampling of population • Data Collection • Analysis • Presentation

  3. Research Process

  4. Research objective • Why? To guide what we want to accomplish in the study. • General Objective • Write an overview of your aims. This will reflect your problem and defines the scope of the study. • Specific Objective • Breakdown your overview into specific areas addressing difference aspects of your problem.

  5. Research Hypothesis • The research hypothesis is a paring down of the problem into something testable and falsifiable. • Research hypothesis can be • 2 tail, researcher not committing to decide the preference decision, ex : there is an association between A and B • 1 tail, the researcher committing to decide the preference of decision, ex: A is better than B.

  6. Study Design

  7. Cross sectional study • Examines the relationship between disease and other variable of interest as they exist in a defined population at one particular time. • Conducted at one period of time or at one time

  8. Cross sectional Disease +, Factor + Disease +, Factor - Population Disease -, Factor + Disease -, Factor -

  9. Case Control • Disease, and non disease group identified, then compared with exposure to risk factor previously. • Case selection : • Case definition • Control selection • Person without disease under study • Can be matching by age, gender,ethnic, socioeconomisetc • Purpose of matching: to select the control that has similar cofounding contribution with case.

  10. Case Control

  11. Case Control Factor + Case Factor - 1: SELECT the case and Control Factor + Control Factor - 2: Determine the exposure to risk

  12. Cohort Study • One or more individual group are defined based on whether exist or not the exposure to the disease factor. • During the exposure status, all subject are free from the studied disease. • It is indicate when exposure is rare but incidence of disease is higher among exposed. • It can be prospective or retrospective cohort..

  13. Cohort Study

  14. Cohort Study • Prospective Disease Disease 1. From population identify group with risk factor & no risk factor Risk factor Present No Disease No Disease Sample Polpulation Risk Factor Absent 2. Follow up

  15. Cohort Study • Retrospective Risk Factor Risk Factor No Risk Factor No Risk Factor Disease Sample population No Disease

  16. Cohort Study • Retrospective Risk Factor Risk Factor No Risk Factor No Risk Factor Disease Sample population No Disease
