Abstract:
We developed a new questionnaire-the Sarcopenia Knowledge Questionnaire (SKQ)-to evaluate the level of awareness about sarcopenia among older adults and tested the reliability and validity of this tool. A total of 293 older adults completed the questionnaire. The SKQ comprises three domains including 23 items: screening and diagnosis (10 items), sarcopenia outcomes (7 items), and lifestyle factors (6 items). The Cronbach's α value was 0.969, which indicated excellent internal consistency. The SKQ correlated well with the Mandarin Multidimensional Health Literacy Questionnaire (r = 0.511; p < 0.001), confirming its moderate convergent validity. The absolute values of the critical ratio ranged from 9.90 to 25.82 (p < 0.001), indicating satisfactory item discrimination. Thus, the SKQ appears to be a valid and reliable instrument for evaluating the knowledge of older adults about sarcopenia.
