Purpose: The purpose of this study was to develop and validate a questionnaire to examine women's beliefs about cervical cancer and the Pap test in Chilean women. Design and Methods: The questionnaire, developed following the guidelines by Robert de Vellis, is based on the Health Belief Model. The content validity index was 0.93 upon review by 10 Chilean experts. A cross-sectional design was implemented to validate the questionnaire. The sample included 333 women recruited from a women's healthcare center in Santiago, Chile. Exploratory factor analysis was used to evaluate validity and coefficient α to evaluate reliability. Findings: After six models were computed, the questionnaire was reduced from 53 to 28 items. The new questionnaire, CPC-28 (in Spanish, Creencias, Papanicolaou, Cancer -28), includes six domains: the barriers domain to take a Pap test, the cues to action domain, the severity domain, the need to have a Pap test domain, the susceptibility to cervical cancer domain, and the benefit domain. The unexpected salient factor "need to have a Pap test" was found as part of the susceptibility domain proposed in the initial questionnaire. This finding is an important topic for future research. The CPC-28 questionnaire explained 49% of the total variance, and the reliability was 735. Conclusions: It was concluded that the CPC-28 questionnaire will have important implications on research, education, and administration across disciplines. Clinical Relevance: Nursing curricula and healthcare providers must stress the importance and reinforce the importance of prevention of cervical cancer and regular Pap test screenings.
