Frailty and the confidence to plan ahead: Decision-making self-efficacy and advance care planning among older adults receiving home healthcare

Objectives The relationship between frailty, self-efficacy, and advance care planning (ACP) remains unclear in Asia. This study examined how frailty status relates to decisional self-efficacy, ACP engagement, and advance directive completion among older adults receiving home healthcare in Taiwan. Methods A cross-sectional analysis was conducted using baseline data from a nationwide cohort in Taiwan. Participants (N = 358) were categorized by Clinical Frailty Scale (CFS): mildly frail (CFS 4–5, n = 60), moderately frail (CFS 6, n = 83), severely frail (CFS 7, n = 147), and very severely frail (CFS 8–9, n = 68). ACP engagement and decision-making self-efficacy were assessed using Likert scales. Results Patients with greater frailty had lower odds of high decisional self-efficacy (CFS: 8–9: odds ratio [OR] = 0.38, 95% confidence interval [CI] = 0.14–1.07) but higher odds of ACP engagement (CFS: 6: OR = 3.38, 95% CI = 1.40–8.17; CFS: 7: OR = 2.52, 95% CI = 1.08–5.89) compared with mildly frail individuals. However, this increase did not extend linearly to the very severely frail group. Advance directive completion remained low across all frailty levels (4.8–10.0%) and was not significantly associated with frailty status. Conclusions Frailty was associated with lower decisional self-efficacy but higher readiness for ACP, revealing a divergence between perceived confidence and planning motivation. Despite greater engagement, advance directive completion remained low. Stage-sensitive, values-based approaches may help bridge the gap between intention and documentation across the frailty spectrum.
