Supplementary file 1_Exercise rehabilitation adherence and associated factors in patients aged ≥75 years with hemorrhagic stroke: a mixed-methods study.docx

Qualitative data were analyzed using Colaizzi’s seven-step method.</p>Results<p>The mean adherence score was 37.97 ± 10.57. Overall, 20.87, 29.53, and 49.60% of participants demonstrated low, moderate, and high adherence, respectively. Multinomial logistic regression showed that higher rehabilitation self-efficacy was associated with lower odds of low adherence.

In contrast, greater illness uncertainty and disease duration ≤6 months were associated with higher odds of low adherence. Greater illness uncertainty, male sex, and disease duration ≤6 months were also associated with moderate adherence. Qualitative analysis identified three themes underlying adherence: cognition and attitudes toward exercise rehabilitation, psychological and emotional disturbances, and external support.</p>Conclusion<p>Exercise rehabilitation adherence varied among patients aged ≥75 years with hemorrhagic stroke and was associated with disease duration, rehabilitation self-efficacy, illness uncertainty, and sex.

The qualitative findings further indicated that patients’ cognition and attitudes, psychological and emotional experiences, and external support shaped their engagement in rehabilitation. These findings highlight the potential value of tailored interventions addressing these multidimensional factors to support engagement in exercise rehabilitation among this vulnerable population.</p>
