Detaljeret beskrivelse
This study adopts a cluster randomized controlled design to implement a group-based non-pharmacological intervention for older adults with subjective cognitive decline.
The effects of the intervention on global cognitive function, episodic memory, executive function, attention, language function, subjective memory function, anxiety, depression, social participation, gait speed, physical activity level, and healthy lifestyle behaviors will be evaluated.
In addition, implementation outcomes will be assessed based on the RE-AIM framework and the CFIR framework.

Episodic memory
Tidsramme: week0，week12，week24
|
Using the Huashan version of the Auditory Verbal Learning Test (AVLT) for assessment, it is mainly used to evaluate immediate recall, short-delay recall, long-delay recall, and other key components.
The test includes 12 words belonging to three semantic categories (4 words per category).
The testing procedure is as follows: The examiner reads out the 12 words in sequence, and the subject immediately recalls them.
This process is repeated three consecutive times to form the immediate memory test.
After an interval of 5 minutes, short-delay recall is conducted, and after 20 minutes, long-delay recall is implemented.
The scoring rule is that each correctly recalled word earns 1 point.
The immediate memory score is the sum of correct recalls from the first three trials (maximum score 36).
This study records the scores for immediate recall, short-delay recall, and long-delay recall, with higher scores indicating better memory function.

Gobal cognitive function
Tidsramme: week0，week12，week24

The assessment uses the Montreal Cognitive Assessment (MoCA).
Higher scores indicate better performance, with a minimum score of 0 and a maximum score of 30.

Executive function
Tidsramme: week0，week12，week24
|
The Shape Trail Test (STT) was used to assess executive function.
The test consists of two parts: Part A requires participants to connect 25 numbers in ascending order; Part B involves 25 numbers presented within two different shapes.
The scoring indicators are the time taken to complete STT-A and STT-B, with shorter completion times indicating better executive function.

Attention
Tidsramme: week0，week12，week24
|
The Digit Symbol Substitution Test (DSST) is used to assess the patient's attention.
The subject is required to match the corresponding symbols to the numbers (1-9) as quickly as possible within 90 seconds.
Each correctly filled symbol earns 1 point, and a reversed symbol earns 0.5 points.
The maximum score for the test is 90.

Linguistic function
Tidsramme: week0，weel12，week24
|
Animal verbal fluency is used to assess a patient's language fluency.
The test requires the subject to name as many examples as possible within the category of animals in one minute.
Scoring is typically based on the total number of correctly named animal names.
Lower scores indicate reduced language ability.

Depression
Tidsramme: week0，weel12，week24
|
The short version of the Geriatric Depression Scale (Geriatric Depression Scale-15, GDS-15) is used for assessment.
The total score ranges from 0 to 15, and the score is positively correlated with the severity of depression.

Anxiety
Tidsramme: week0，week12，week24
|
The Geriatric Anxiety Inventory-20 (GAI-20) is used for assessment.
This scale consists of 20 items, and respondents answer based on their emotional feelings over the past week.
A response of "Yes" is scored as 1 point, while "No" is scored as 0 points.
The total score ranges from 0 to 20, with higher scores indicating more severe anxiety.

Social network
Tidsramme: week0，week12，week24

The Lubben Social Network Scale-6 (LSNS-6) is a short version of the Lubben Social Network Scale.
It is primarily used to measure an individual's level of social connectedness in two dimensions: family relationships and peer interactions.
The scale consists of six assessment items and uses a graded scoring system: 0 points indicate no such social members, 1 point corresponds to 1 person, 2 points to 2 people, 3 points to 3-4 people, 4 points to 5-8 people, and 5 points applies to groups of 9 or more individuals.
Lower scores indicate poorer levels of social network connectedness.

Social participation
Tidsramme: week0，week12，week24
|
This study employed the Social Participation Level Assessment Tool revised by Wei Xiuping, which was developed based on national health survey data of the elderly population.
The measurement tool comprises two main dimensions: cultural organization participation and family/personal affairs, encompassing a total of 10 specific items.
A five-point Likert scale was used for measurement, and the total score is positively correlated with the level of social participation-that is, a higher score indicates a more significant degree of social participation among the respondents.

Timed "Up and Go" test
Tidsramme: week0，week12，week24
|
During the test, the participant sits on a chair with armrests and a backrest.
Upon hearing the instruction, they stand up, walk 3 meters forward at their usual gait, then turn around, return to the chair, and sit down.
The average of two test trials is recorded.
