Knowledge (information support, changing health attitudes); Motivation (motivation to change sedentary behaviour and improve exercise compliance); Capacity (development of exercise plans to improve sedentary behaviour change); Opportunities (increasing the timing of exercise and creating opportunities for sedentary behaviour change); Behaviour (monitoring and reinforcing sedentary behaviour change)

COM-B-based development of specific sedentary behavioral interventions to reduce sedentary time, promote healthy activity, and improve quality of life in older stroke patients

International Physical Activity Questionnaire (IPAQ) Sedentary behavior and physical activity levels were assessed using the International Physical Activity Questionnaire (IPAQ), which was developed by the International Physical Activity Measurement Working Group (IPAMWG) in 2001, with the coefficients for sedentary behavior and validity scale correlation coefficients of 0.887 and 0.760 for sedentary behavior and 0.779 and 0.718 for physical activity, respectively. In this questionnaire, the metabolic equivalent of walking was 3.3, moderate activity intensity was 4.0, and high intensity activity was 8.0. The formula for calculating sedentary time was: sedentary time per day = (weekday sitting time x 5 + weekend sitting time x 2)/7

Social Support Rating Scale (SSRS) This scale is mainly used for the evaluation of individual social support status, with 10 entries, including 3 dimensions of subjective support, objective support and utilization of support. The scoring method is the sum of the scores of each entry, and the higher the score, the higher the level of social support. The scale reliability coefficient was 0.896.

The Self-Rating Depression Scale (SDS) Self-Rating Depression Scale (SDS) is a 20-item self-rating scale, with scores of 1, 2, 3, and 4 for each item, and the sum of the scores of all items ranging from 53-62 indicating mild depression; 63-72 indicating moderate depression; and more than 72 indicating severe depression. The higher the total score, the more severe the depression. The Cronbach's alpha coefficient of the scale was 0.920.

Functional Exercise Adherence Scale for Stroke Patients (Questionnaire of Exercise Adherence, EAQ) The EAQ was developed by Beilei Lin in 2013 to assess patients' adherence to rehabilitation exercises. It contains 14 entries divided into 3 dimensions (physical participation in exercise, exercise effect monitoring and active seeking of exercise advice adherence), with each entry scored on a scale of 1 to 4. The total score of the scale ranges from 14 to 56, and the adherence index is the percentage value of the patient's measured score to the maximum score of the scale (56). The level of patient adherence was judged according to the adherence index: ≤50% = low level, 50% to 75% = medium level, and ≥75% = high level. The scale had good content validity (0.95), structural validity and validity scale validity, and high retest reliability (ICC: 0.778-0.850) and internal consistency (Cronbach's alpha coefficient: 0.923).
