Objective: The aim of the work was to validate the Slovak version of the CPC-28 questionnaire (Beliefs about Papanicolaou and Cervical Cancer).
Design: Original study.
Setting: Department of Public Health, Jessenius Faculty of Medicine in Martin, Comenius University in Bratislava, in co-operation with gynaecological centers in University Hospital Martin and district Martin, Slovakia.
Methods: The original English version of the CPC-28 questionnaire was translated into Slovak language. The questionnaire consists of 28 statements divided into six domains. Cronbach´s alpha coefficient was used to analyse the internal consistency of the questionnaire. Construction validity was evaluated by using Pearsons correlation coefficient. The results were processed in the statistical programs Epi Info 7.1.5. and Statistica 13, p-values < 0.05 were considered statistically significant.
Results: The Slovak version of the questionnaire was provided to 27 women. The women were given two questionnaires, and one of them was filled in immediately (test). After 14 days they filled in and returned second questionnaire (retest). The value of Cronbachs alpha was > 0.8 in all six domains which demonstrates the high internal consistency of the questionnaire. Pearsons coefficient was > 0.7 in all six domains and p-values < 0.001.
Conclusion: The validated CPC-28 questionnaire in the Slovak language can be administered to women to collect data for identification of barriers to cervical cancer screening among women.
