Background: Cardiac patients’ beliefs about illness and treatment can disturb their treatment process, treatment regimen adherence, and daily activities. Exploring these beliefs by the use of appropriate, valid, and accurate scales can be helpful in false beliefs reforming by nurses and finally, result in life quality promotion. Therefore, this study is conducted to design and psychometry a questionnaire probing about cardiac patients’ beliefs about illness and treatment.
   Methods: The sequential combination exploratory mixed methods design was used to develop the questionnaire format, which involved two sections: the quantitative and qualitative step. The qualitative step included probing the role of cultural beliefs about illness and treatment in two steps, including the literature and related tools review and fieldwork (semi-structured interviews with cardiac patients). Seventeen studies were checked in the literature review. Twenty-two cardiac patients were selected and interviewed by purposive sampling. The interviews continued up to the data saturation. The data analysis was conducted in both steps using conventional content analysis and textual content analysis. The quantitative step was a methodology study accomplished in two parts. The questionnaire items were formed using the data and items pool in the first part while the psychometric properties of the questionnaire were checked using face, content and construct validity and the reliability was probed using internal consistency and stability in the second part. The data were transferred into SPSS software program, version 18.0 for Windows (α<0.05).
   Results: 319 codes were extracted from the analyzing phase which formed 6 categories including prognosis, prevention, contexts, treatment efficiency, mentality and lifestyle as well as 9  sub-categories including understanding the danger, attitude toward disease, attitude toward treatment, society’s culture, feeling hopeless, treatment regimen ignorance, self-curing, trying to survive and physical outcomes.
The items pool was formed using literature reviews and interviews. A 30-itemed questionnaire was formed after the psychometric process. The Kaiser-Meyer-Olkin (KMO) index and the Bartlett’s test of sphericity showed good results. Six components from the exploratory content analysis including prognosis, prevention, contexts, treatment efficiency, mentality, and lifestyle gained 51.7% variance totally. The interclass correlation coefficient was 0.83 in responding to the items for two times.
   Conclusion: This study developed a questionnaire about cardiac patients’ beliefs regarding their illness and treatment. It can be used for the educational, research, and treatment purposes as a questionnaire with short, easy, and grammatically simple items that have appropriate validity and reliability. Using this scale can be helpful in evaluating clients’ beliefs and recognize their educational needs.
