No Intervention: standard clinical care

The experimental group utilized a cartoon version of the "Advance Care Consultation for the Elderly" manual to facilitate the ACP process, which encompassed three components: an introduction to ACP, an overview of terminal medical care, and a discussion about the participants' preferences for their past, current, and future required medical care. There are three measurement time points: pre-test, two weeks after intervention, and one month after intervention.

The questionnaire is scored using a 5-point Likert scale. There are a total of 12 questions, resulting in a total score ranging from 24 to 120, with responses ranging from "strongly disagree" (1 point) to "strongly agree" (5 points) . A higher score indicates a more positive attitude among the elderly towards advance care planning.

The scale is scored using a 5-point Likert scale. There are a total of six questions, resulting in a total score ranging from 6 to 30, with responses ranging from "very unlikely" (1 point) to "very likely" (5 points)

The scale consists of 20 questions, each with 4 options: "completely does not fit," "fits slightly," "fits," and "fits very well." Out of these, 10 questions are positively framed (3, 4, 6, 7, 9, 12, 13, 14, 17, and 18). The scoring is as follows: "1 point" for "completely does not fit," "2 points" for "fits slightly," "3 points" for "fits," and "4 points" for "fits very well." The remaining ten questions are negatively framed, and scoring is reversed, with "4 points" for "completely does not fit," "3 points" for "fits slightly," "2 points" for "fits," and "1 point" for "fits very well." The total score ranges from 20 to 80 points. A higher score indicates a higher level of anxiety, with scores of 20 to 39 indicating mild anxiety, 40 to 59 indicating moderate anxiety, and 60 to 80 indicating severe anxiety.

The scale is scored using a 4-point Likert scale, with "1 point" indicating "strongly disagree" and "4 points" indicating "strongly agree," resulting in a total score ranging from 12 to 48 points.
