Abstract :
BACKGROUND: The present study describes the methods of developing and validating two
questionnaires that will be used to investigate the knowledge, attitude and practice of adults,
children and adolescents regarding obesity.
METHODS: To design the questionnaires, we used the components of the Health Belief Model.
The questionnaire for adults consisted of 6 sections with 50 questions. The questionnaire for
children and adolescents included 7 sections and 52 questions. The questionnaires were
assessed for face validity, content validity, and clarity of the items. To determine the internal
consistency reliability of the questionnaires, Cronbachʹs alpha coefficient was measured for 100
questionnaires. Using the correlation coefficient, we determined the equivalent reliability of the
study tools.
RESULTS: The Cronbachʹs alpha coefficient ranged between 0.60 and 0.80 for the whole
questionnaires. The Cronbachʹs alpha coefficient of the questionnaires for adults, children and
adolescents were respectively 0.72 and 0.60 for awareness. The corresponding values for
attitude were 0.70 and 0.75. Using Pearsonʹs correlation coefficient, the interobserver
reliability was determined to be significant (r ? 0.80; P < 0.001).
CONCLUSION: Our study tools had adequate reliability and validity. They are thus suitable for
assessing the knowledge, attitude, and practices of Iranian adults, and children and adolescents
in toward obesity.
