Abstract

Introduction: Cervical cancer (CC) treatment-related adverse events (AEs) were found to be among the major reasons for treatments delays and medication non-adherence. Knowledge and practice of self-care management of these AEs are therefore needed to complement the pharmacotherapeutic interventions. Instruments for assessing CC patients' knowledge and practice of self-care management of treatment-related Adverse Events (AEs) are lacking. Hence, the rational for this study.

Methods: A prospective, cross-sectional study was conducted on CC patients receiving chemotherapy, radiotherapy or both, with or without surgery in Usmanu Danfodiyo University Teaching Hospital (UDUTH) Sokoto, a tertiary hospital in North-Western Nigeria. A panel of 14 experts judged the content validity of the items initially selected. Purposive sampling technique was used, 31 CC patients were recruited and interviewed for the questionnaire pre-testing. Descriptive statistics and psychometric analysis were conducted using SPSS Version 20.0 for Windows. A Cronbach's alpha coefficient ≥0.70 was considered acceptable.

Results: A 12-domain questionnaire instrument was developed. Eight (57.1%) of the expert panelists rated the questions' items as "Very good for the study" and none of them rated any of the content "not relevant for the study". The reliability studies showed that the overall knowledge and practice questions response rates were 71.0% and 77.4% and Cronbach's alpha (α) values were 0.956 and 0.913, respectively.

Conclusion: A reliable, 12-domain cervical cancer patients' knowledge and practice of self-care management of treatment-related adverse events questionnaire was developed. Further research on the psychometric qualities of the instrument is needed.
