It impairs older adults' independent living ability and quality of life, and also places substantial physical, emotional, and economic strain on family caregivers, with spouses being the primary source of informal care in community settings. Epidemiological evidence has documented a spousal concordance effect for cognitive impairment: spouses of people with cognitive decline face a significantly elevated risk of developing cognitive impairment themselves, driven by shared lifestyles, common risk factors, and long-term caregiving stress. Most current interventions target either the patient or the caregiver as an individual, rather than treating the couple as an interdependent dyadic unit.\n\nTo address this research gap, this study applies the Theory of Dyadic Illness Management (TDIM) to develop and test a couple-centered cognitive intervention for community-dwelling older adults with mild cognitive impairment and their spouses. The core premise of the theory is that illness management is a shared process within a couple: shared appraisal of the condition, collaborative disease management behaviors, and mutual support together shape health outcomes for both partners. This study moves beyond the traditional patient-only or caregiver-only intervention model, and instead designs the program around the dyad to target shared risk factors and support joint coping.\n\nThis is a single-center, parallel-group randomized controlled trial conducted in an urban community health service setting in China. A total of 68 eligible older couples (in which one partner meets diagnostic criteria for mild cognitive impairment and the other serves as the spousal caregiver) will be enrolled. Eligible couples will be randomly allocated to either the intervention group or the control group in a 1:1 ratio. To reduce measurement and analytic bias, outcome assessors and data analysts will be blinded to group assignment throughout the study.\n\nParticipants assigned to the control group will receive standard community health education covering cognitive impairment risk factors, early warning signs, basic care knowledge, and healthy lifestyle guidance. Participants assigned to the intervention group will receive the same standard health education, plus a structured dyadic cognitive intervention program. The intervention is designed for joint participation by both members of the couple, and focuses on building a shared understanding of cognitive health, practicing collaborative cognitive maintenance strategies, developing dyadic coping and communication skills, and establishing shared healthy daily routines.\n\nAll enrolled couples will complete follow-up assessments at three time points: baseline (prior to randomization), 3 months post-intervention, and 6 months post-intervention. Assessments will cover multiple core domains of dyadic health: cognitive function of the older adult with impairment, daily living functional status, emotional well-being for both partners, overall quality of life, dyadic coping capacity of the couple, and caregiving burden experienced by the spouse.\n\nThis trial aims to generate evidence regarding the effectiveness, feasibility, and acceptability of a couple-based cognitive intervention in a Chinese community context. The findings are expected to provide a practical, evidence-based intervention model for primary care and community health services, and to support the transition from individual-focused cognitive care to dyadic, couple-centered care for older adults with cognitive impairment and their families.",[42,48],{"label":43,"type":44,"description":45,"interventionNames":46},"Dyadic Intervention Group","EXPERIMENTAL","This arm receives standard community health education plus an 8-week theory-based dyadic cognitive intervention, in which both the older adult with mild cognitive impairment and their spousal caregiver participate as a dyadic unit.
