  1. Nagelkerke R = explained variance of the block with included determinants [28].
  2. K2: Determinant Knowledge 2, is malaria transmitted by contaminated food?
  3. K3: Determinant Knowledge 3, is malaria transmitted by infected people?
  4. K6: Determinant Knowledge 6, are you vaccinated against malaria?
  5. A1: Determinant Attitude 1, I am afraid of side effects.
  6. A3: Determinant Attitude 3, I have faith in malaria tablets.
  7. A4: Determinant Attitude 4, it is easier to cure malaria than take tablets.
  8. R4: Determinant Risk perception 4, I am immune for malaria.
  9. S2: Determinant Social 2, my friends/ family encourage use of tables.
  10. S3: Determinant Social 3, my friends/ family discourage use of tablets.
  11. PBC 1: Determinant Perceived Behaviour Control 1, I think I could forget a tablet.
  12. PBC 3: Perceived Behaviour Control 3, do you feel well informed of malaria.
  13. E1: Determinant Previous experience, have you used tablets in the past?
  14. Significant outcomes are indicated in boldface.
