| Abstract: | ObjectiveTo develop and test the content validity of the Self-Care of Oral Anticancer Agents Index (SCOAAI).Data SourcesSCOAAI items were developed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) criteria. The Middle Range Theory of Self-Care of Chronic Illnesses informed item generation. A four-phase procedure was followed; Phase 1: items were created based on a previous systematic review and a qualitative study; Phase 2: the SCOAAI comprehensibility and comprehensiveness were established through qualitative interviews with clinical experts and with patients (Phase 3); and Phase 4: the SCOAAI was then administered through an online survey to a group of clinical experts for the Content Validity Index (CVI) calculation.ConclusionThe first version of the SCOAAI included 27 items. Five clinical experts and 10 patients tested the comprehensiveness and comprehensibility of instructions, items, and response options. Fifty-three experts (71.7% female, mean experience with patients on oral anticancer agents 5.8 years standard deviation ± .2]; 66% nurses) participated in the online survey for content validity testing. The final version of the SCOAAI includes 32 items. Item CVI ranges between 0.79 and 1; the average Scale CVI is 0.95. Future studies will test the psychometric properties of the tool.Implications for Nursing PracticeThe SCOAAI showed excellent content validity, confirming its usefulness for assessing self-care behaviors for patients on oral anticancer agents. By implementing this instrument, nurses could define and implement targeted interventions for improving self-care and obtaining more positive outcomes (eg, better quality of life, reduced hospitalizations and emergency department visits). |
