An Akan Translation, Validation and Reliability of a Questionnaire for assessing Awareness of Ghanaian women on Prostate Cancer

Abstract

Objectives: The study aimed to: (1) adopt, modify and develop a questionnaire suitable for data collection on prostate cancer in the female population, (2) translate the questionnaire into the Akan language, and (3) conduct a validity and reliability analysis on the Akan questionnaire. Methods: An English version questionnaire was developed and adequately translated into an Akan version according to the forward and backward translation protocols. The Akan questionnaire went through translator-approval and certification. Validity and reliability analysis were performed on the questionnaire. Statistical analysis for face validity involved the determination of average scores while content validity involved the determination of the content validity index. Regarding reliability analysis, Cronbach’s alpha was calculated for the test and retest periods of study. Results: A forty-five (45) membered Akan questionnaire was successfully developed and certified. The average scores for all parameters employed in the face validation were greater than 4. The content validity index was within the range of 0.90 - 0.99 while the Cronbach’s alpha for both test periods was within the range of 0.7808 - 0.9209. Conclusion: The Akan questionnaire had acceptable validity and reliability outcome. Therefore, the questionnaire was considered appropriate for assessing knowledge, awareness, and perception of Ghanaian women of prostate cancer.
