Each participant signed an informed consent and was interviewed with the SXI\u2010ID. A subset of participants was interviewed again after two weeks. A standard question was used to check criterion\u2010related validity, by plotting the mean SXI\u2010ID scale scores against the ordinal response categories of the standard question. The reliability check included Cronbach's alpha, total and inter\u2010item correlation, and intraclass correlation for internal consistency, along with test\u2010retest reliability.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 110 older adults participated.
