Validation and Pilot Study
A prelimanary phase was made to evaluate the validity and reliability of
the questionnaire prior to its use. Primarily, two Turkısh specialists
in the subject area of epidemiology and research in Turkısh universities
were asked to evaluate the grade to which questions in the
questionnaires are relevant regarding COVID-19. Also the survey
questions were modified and edited accordingly.
The survey was pre-tested on 15 participants excluded from the study
sample. The patients were requested to fill the questionnaire twice
one week apart. Information were used to evaluate internal consistency
reliability using cronbach’s alpha. The cronbach’s alpha value of the
pilot study was 0.90 and the intra-class correlation coefficient was
0.83. That is, results showed sufficient internal consistency
reliability.
