Abstract

BACKGROUND:

Timely prevention of type 2 diabetes decrease socio-economic burden of disease in a society. To measure people's knowledge, the existence of valid and accurate tool such as questionnaires is very important. In the study we tried to make a comprehensive questionnaire to measure knowledge of apparently healthy individuals.

MATERIAL AND METHODS:

In this study a questionnaire to assess general population awareness about type II diabetes disease and its complications was Design, developing and validation based on 10 experts' panel and statistical inferences.

RESULTS:

Initially 67 questions designed and according to the experts' panel 16 questions were removed and 11 questions were edited. Finally, content validity of 51 questions has been approved by the experts' panel. According to Lawshe's score if CVRs were at least 0.8, items will be has content validity. The results show that both internal consistency and intra-class-correlation were good (>0.75). Cronbach's alpha and ICC were 0.84 and 0.82, respectively for all questions. To confirm structure of conceptual model, confirmatory factor analysis and Amos software was used. Goodness of Fit Index was RMSEA=0.027, GFI=0.95, AGFI=0.91, CFI=0.97; and showed that the hypothesized model is approved.

CONCLUSION:

In general, we can say that the questionnaire is approximately comprehensive and complete. It is suggested that to assess awareness of diabetes type 2 in seven dominants (e.g. fundamentals, common symptoms, early and late complications, diet, control methods, and source of information of DMT2) this questionnaire should be used in general population.
