2. Pilot study Pilot studies are used as “feasibility studies”, to ensure that the ideas or methods behind a research idea are sound, as well as to “work out the kinks” in a study protocol before launching a larger study.

3. Definition “ The study carried out at the end of planning phase of research, in order to explore and tests the research elements”. BT Basavanthappa (2000)

4. Definition “It is a small - scale version or trial run done in preparation for a major study.” Polit & Hunglar

5. Pilot study Pilot study is a small scale preliminary study conducted in order to evaluate feasibility, time, cost, adverse events, and affect size (Statistical variability) in an attempt to predict an appropriate sample size and improve upon the study design prior to performance of a full scale research project.

6. Purposes

7. Advantages of pilot study

8. Reason 1 To determine the feasibility of the study protocol and identify weaknesses in a study

9. Reason 2 To test whether the study instrument(s), is asking the intended questions, whether the format is comprehensible and whether the selected validated tool is appropriate for the target population.

10. Reason 3 To test the appropriateness of data collection using the selected interview technique (face-to-face or telephone) or self-completed questionnaire (postal or administered at the centre).

11. Reason 4 To test the data collection process – the time taken to complete questionnaire, and the subjects’ willingness to participate in the study.

12. Reason 5 To test data entry, coding of the items, and appropriateness of statistical tests

13. Reason 6 To obtain preliminary data for the primary outcome measure, in order to calculate a required sample size (especially in randomized control trials).
