Applying the Decomposed Theory of Planned Behavior to Explore Long-Term Care Residents’ Participation in an Augmented Reality Aromatherapy Education Program
This study examined the applicability of the Decomposed Theory of Planned Behavior (DTPB) in understanding long-term care residents’ intention to continue using an augmented reality (AR) aromatherapy education program designed to manage behavioral and psychological symptoms of dementia (BPSD). Eighty-five residents participated in a cross-sectional survey following their experience with a series of AR-based modules. Partial least squares structural equation modeling showed that attitude, subjective norms, and perceived behavioral control significantly predicted continuous use intention, explaining 69.0% of the variance. Perceived usefulness and playfulness shaped attitude, while interpersonal influence and self-efficacy influenced subjective norms and perceived behavioral control, respectively. Perceived usefulness demonstrated both direct and indirect effects on use intention. Findings support the theoretical fit of the DTPB in evaluating technology-based interventions for older adults. Integration of AR aromatherapy education into long-term care may enhance resident engagement and support non-pharmacological BPSD management.
