The study aimed to evaluate the effects of a 6-month FANS on frailty status and health-related quality of life in community-dwelling frail older adults, and to compare the effects on fall efficacy, pain intensity, daily activities, stages of physical activity and nutrition behavior change, and satisfaction following the intervention.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;A quasi-experimental design was used to assess the FANS among frail older adults (ClinicalTrials.gov Identifier NCT05242549). The intervention, based on the Transtheoretical Model, was conducted in a mixed setting, combining in-person sessions held at a community care center and remote group care delivered through the LINE app. The experimental group (43 individuals) received the FANS intervention, while the control group (38 individuals) continued with standard health promotion activities provided at the same community care center. Intention-to-treat analysis evaluated the intervention's impact. Measurements were taken before the intervention and at the 3-month and 6-month marks to assess changes in frailty status (using Cardiovascular Health Study criteria), health-related quality of life (Short Form-12), fall efficacy (Short Falls Efficacy Scale International), pain intensity (Pain Visual Analogue Scale), and daily activities (Instrumental Activities of Daily Living scale).
