Barriers and Facilitators to Cognitive Function Interventions in Rural Diabetic Older Adults: Using the COM‐B Model and Theoretical Domains Framework

ABSTRACT Aims We aimed to identify the barriers and facilitators to participation in interventions aimed at improving cognitive function among older adults with type 2 diabetes mellitus (T2DM) and mild cognitive impairment (MCI) in rural areas. Design This study is the qualitative phase of a larger randomised controlled trial and employs a descriptive approach. Methods We conducted in‐depth, semi‐structured face‐to‐face interviews with older adults diagnosed with T2DM and MCI in rural areas of China in November 2023. The interviews were guided by the Capability, Opportunity, Motivation, and Behaviour (COM‐B) model and the Theoretical Domains Framework (TDF). The interview recordings were transcribed and analysed using NVivo V.11 software. Two research assistants independently coded the transcriptions, and the identified barriers and facilitators were mapped to the corresponding domains within the COM‐B model and TDF. Results A total of 26 older adults, aged 60–87, participated in the interviews. Nine themes were identified, including disease awareness, disease attitude, social interaction, responsibility and health, emotion guidance, organisational management, expertise and benefits, self‐perception and role identity crisis. These themes mapped onto the three core components of the COM‐B model as well as the nine domains of the TDF, which include: knowledge, environmental context and resources, social influences, intentions, emotions, reinforcement, beliefs about consequences, beliefs about capabilities and social identity. Conclusion Addressing barriers and leveraging facilitators can effectively enhance the willingness of elderly patients in rural areas to participate in interventions aimed at improving cognitive function. A multi‐layered approach should be adopted, focusing on disease knowledge and attitudes, social interactions, the impact of the disease burden on both family and individuals, emotional state, organisational management, team expertise and timely assessment, individual self‐efficacy and role perception. Reporting Method The study adheres to the COREQ reporting guidelines. Patient or Public Contribution The participants in this study were older adults with T2DM and MCI from rural areas. Participants were involved in the development of the interview guide and were subsequently interviewed regarding the facilitators and barriers to their participation in cognitive function interventions.
