摘要

There is a lack of reliable tools to assess the knowledge of frailty and malnutrition in community-dwelling older adults. To develop and validate reliable frailty and malnutrition knowledge assessment scales for this population, two scales were developed and validated through five phases. Phase 1: the item pools were constructed through a literature review and research panel based on the symptom interpretation model. Phase 2: the expert consultation was performed to select the items. Phase 3: a pilot survey was conducted to assess the clarity of the items and further revise the scales. Phase 4: 242 older adults were surveyed to finalize the items. Phase 5: 241 older adults were surveyed to test the psychometric properties. The two scales each comprise 3 dimensions (symptoms, risk factors, and management strategies) and 11 items. They had good construct validity, with all indicators of correlation analysis and confirmatory factor analysis meeting their specific criteria. The reliability of the frailty and malnutrition knowledge assessment scales was good, with composite reliability coefficients all >0.60, Cronbach's alpha being 0.81 and 0.83, and the Spearman–Brown coefficient being 0.74 and 0.80, respectively. Their acceptability was good, with both having a completion rate of 92.18% and an average completion time of 3 min. The two scales are reliable tools to assess the knowledge of frailty and malnutrition among community-dwelling older adults, especially for large-scale surveys. They can help identify knowledge gaps in older adults and provide a basis for developing targeted educational interventions.
