    2. Exercise 1 A maternity hospital wishes to determine if the offer of family planning methods, post-partum, will increase contraceptive use among women who deliver at the hospital 15,000 women per year deliver at the hospital in 10 wards. The average woman who gives birth at the hospital receives 3 pre-natal and 0.5 post-natal visits

    3. Question What designs would you recommend to test the hypothesis that women who are offered post-partum family planning services are more likely to use family planning than women who are not offered services? a. Outcome indicator(s)? b. Describe the intervention c. Experimental design d. Random assignment - what will you assign: patients, providers, wards?

    4. Exercise 2 The hospital is not available for your study, but you can use 10 health centers, each with a maternity ward a. What will you randomly assign? b. Or would you want to use matching? What factors would you match on? c. What design will you use if you cannot randomly assign?

    5. Exercise 3 A program may add injectables to family planning methods offered Some think injectables can be made available through community health workers (CHWs), arguing it will increase rural contraceptive prevalence Others believe the risks of allowing CHWs to provide DMPA (poor infection prevention and counseling) outweigh increases in prevalence

    6. Question How many problems? How many dependent variables? What design would you use to compare these two points of view? Can you use random assignment?

    7. Exercise 4 Free vasectomies will be offered for one day only in a large gymnasium. 1,000 men are expected to attend. The program wants to compare the effectiveness of no-scalpel vasectomy with traditional surgical technique.

    8. Question Any barriers to random assignment? What design will you use? What are main ethical considerations?

    9. Exercise 5 A study will compare the effect of increasing time devoted to sex education from 3 to 18 hours Operationally define underlined terms Adolescent boys will use more condoms if they receive more sex education.

    10. Exercise 6 Design an experiment to learn if male peer educators refer more clients for VCT than female peer educators. Define underlined terms. Men will refer more clients than women Can you use random assignment in this study? What would you randomly assign?

    11. Exercise 7 Operationally Define These Terms Client satisfaction Quality of care High Risk Group If you cant define and measure it, you dont know what it is.

    12. Exercise 8 Describe Independent Variable The independent variable is a training course for supervisors that will improve their knowledge of malaria.

    13. Exercise 9 Monitor the Intervention Explain how you would monitor the supervision intervention. Was the course taught as described? Did the supervisors practice what they learned?
