Exclusion Criteria for Older Adults * Temporary residents or individuals absent from the study area during the study period. * Individuals with severe cognitive impairment or lack of mental capacity to complete the questionnaire. * Individuals with acute medical conditions in severe/critical stages, those diagnosed with other psychiatric disorders, or those uncooperative during the study process. Exclusion Criteria for Primary Caregivers * Refusal to participate or lacking capacity to complete the interview due to severe cognitive impairment, dementia, or severe psychiatric disorders. * Currently suffering from severe physical or mental health deterioration (e.g., undergoing emergency medical treatment, severe fever) that significantly impairs their ability to respond to the interview.
