The Effectiveness of Interventions Targeting Self-Perception of Aging in Older Adults With Subjective Cognitive Decline
Subjective cognitive decline (SCD) represents the initial clinical manifestation in the disease spectrum of Alzheimer's Disease (AD). It represents an essential stage for early prevention and treatment of cognitive impairment, making the SCD population an optimal target for prior intervention. This study aims to assess the feasibility and efficacy of an 8-week intervention targeting self-perception of aging in community-dwelling older adults with SCD.

Подробное описание
Dementia, especially Alzheimer's Disease (AD), is a major healthcare issue in aging populations. It not only threatens the physical and mental health of older adults but also imposes significant economic and caregiving burdens on families and society. As a preclinical stage of AD, subjective cognitive decline (SCD) is regarded as the optimal phase for early intervention in cognitive impairment. When confronted with the threats of physical, psychological, and social aging, older adults with SCD often hold negative perceptions and emotional responses toward their own aging. They tend to attribute physical decline and memory loss to normal aging processes, overlooking controllable factors, which poses potential risks to their future cognitive outcomes, such as accelerated cognitive decline, elevated dementia risk, and increased accumulation of AD biomarkers. This study is based on the Transactional Model of Stress and Coping (TMSC) and identifies the mechanisms through which self-perception of aging influences cognitive function in older adults with SCD. A comprehensive 8-week intervention program was developed to target these mechanisms. The 8-week intervention program aims to provide practical evidence for delaying cognitive decline in older adults with SCD by enhancing their positive perceptions of aging.

Экспериментальный: 8-week intervention targeting self-perception of aging
Participants in this condition will receive an 8-week intervention targeting self-perception of aging. Group sessions will be held at community health service centers, with one session per week, each lasting 45 to 60 minutes. Additionally, homework assignments will be supplemented, and researchers will provide additional remote support via WeChat. |
The intervention program aims to help older adults with subjective cognitive decline understand the aging process and adopt a positive attitude toward aging, highlighting age-related benefits. The sessions also provide emotion regulation techniques and stress-coping strategies to encourage proactive problem-solving and build confidence in handling challenges. By recalling positive life experiences, the program seeks to strengthen emotional connections, enhance the sense of belonging, and reconstruct a meaningful later life. |

The Montreal Cognitive Assessment Beijing Version (MoCA-Beijing) encompasses multiple cognitive domains, including visuospatial execution ability, naming, memory and delayed recall, attention, language, abstraction, and orientation. The total score ranges from 0 to 30 points, and the higher the score, the better the overall cognitive function. Assessment tools of other cognitive domains will be used depending on the progress of the intervention program. |

The Chinese version of the Brief Aging Perceptions Questionnaire (B-APQ) comprises 17 items grouped into 5 dimensions. Participants rated their agreement on a Likert 5-point scale ranging from "strongly disagree" to "strongly agree" (1 to 5 scores). The total score ranges from 17 to 85 points, with higher scores indicating more negative self-perceived aging. |
