After the validation, the instrument was tested for
reliability. The test-retest method was used, whereby the instrument was
administered to 10 persons outside the study area and results recorded. After
an interval of two weeks, the same instrument was administered to another 10
persons. The results of both instances were compared and the results were found
to be related, hence the instrument was said to be reliable. Based on this, the
supervisor then approved it to be used.
