Objective To investigate the intermediary effect of depression between housebound and cognition in community-dwelling older adults and to provide intervention for the improvement of the life quality.Methods A total of 720 senior adults were selected to fill out demographic questionnaire,including Rasch-Derived Center for Epidemiological Studies Depression Scale (CES-D-R),housebound scale and the minimental state examination (MMES).Results The depression score of the elderly in community was (3.95±4.12),housebound score was (4.26±1.23),cognition score was (21.52±4.04) and the incidence rate of the cognitive disorder was 37.1%.Cognition was significantly negatively related to housebound and depression (r=-0.409,P<0.01;r=-0.485,P<0.01).Housebound was significantly positively related to depression (r=0.555,P<0.01).The community elderly age,sex,marital status,degree of education,self-assessment of health,living space,depression and the housebound could be used to predict the cognitive function,and all of them could explain the variance of cognitive function of 50.8%(P<0.05).Housebound had a direct effect of-0.02 on cognitive function(P>0.05).The indirect effect of housebound on cognitive function through depressive mood was-0.45(P<0.05).Conclusions The elderly housebound has an intermediary effect on the cognitive function through the depression.

Objective To explore the relationship between ageing perception and successful aging.Methods The Brief Aging Perceptions Questionnaire (B-APQ) and Successful Aging Scale were used in 700 community elderly people.Results Different sex,age,degree of education,spouse status,income level,exercise had significantly impact on the score of aging perception and successful aging (P＜0.05).The total mean score of successful ageing was (41.35± 10.66),and the total score of ageing perception was (47.43± 13.88).The total score of aging perception and the total score of successful aging were negative correlation(r =-0.768,P＜0.01).Multiple liner regression results showed that positive,control positive and timeline-chronic dimension played significant roles in successful ageing(P＜0.01).Conclusions Aging perception is associated with successful aging.Phychological and behavioral intervention for the elderly can promote the successful aging.

Objective To examine the reliability and validity of the Chinese version of the confidence after stroke measure(CaSM).Methods The reliability and validity of the Chinese version of CaSM were tested among 280 stroke patients in Jinzhou city.All the data were analyzed by SPSS20.0 and AMOS17.0.Results The Cronbach's α of the overall scale was 0.974,and that of subscales were 0.941,0.954,0.908,the Guttman split-half coefficient was 0.960,the retest reliability was 0.891.All the entries-total scores were significantly positive related (r=0.542-0.901,P＜0.05),I-CVI were 0.830-1.000,S-CVI/UA was 0.815 and S-CVI/Ave was 0.969.Three-factors (self-confidence,positive attitude,social confidence) models were got by using exploratory factor analysis and the communalities of the items were 0.468-0.828.KMO was 0.938,explaining 70.731％ variance.Confirmatory factors analysis showed that the fit indices were x2/df=2.5918,RMSEA =0.077,GFI =0.930,AGFI =0.902,TLI =0.927,IFI =0.943,NFI =0.911,CFI =0.943,standardized regression coefficient were 0.48-0.90.The criterion-related validity between CaSM and SSEQ was positively related (r=0.781,P＜0.01).Conclusions The Chinese version of the CaSM is a reliable and valid instrument which can be used to measure the level of confidence after stroke in China.

Objective:To explore the reliability and validity of the community commitment scale (CCS) in community-dwelling elderly people.Methods:From May to August in 2020, a total of 526 community-dwelling elderly were investigated by community commitment scale, community's self-efficacy scale for preventing social isolation (CSES). SPSS 25.0 and AMOS 22.0 softwares were used to analyze the reliability and validity.Results:The overall Cronbach's α coefficient of the community commitment scale was 0.818, and the Cronbach's α coefficients of social and belonging dimensions were 0.750 and 0.777, respectively. The Guttman split-half reliability coefficients were 0.799-0.835, and the test-retest reliability was 0.802. Each item-to-total score correlations were 0.614-0.753 (all P<0.05). The item level content validity index (I-CVI) was 0.830-1.000, the scale level content validity index (S-CVI/UA) was 0.875, and the average content validity index (S-CVI/Ave) was 0.972. Two common factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 57.019%. The confirmatory factor analysis all indicators reached the adaptation standard (χ 2/ df=2.638, RMSEA=0.079, GFI=0.957, AGFI=0.918, TLI=0.936, CFI=0.956, IFI=0.957), and standardized regression coefficients were 0.63-0.80. Conclusion:The Chinese version of the community commitment scale has good reliability and validity and can be used to evaluate the social isolation of the elderly in the community.

Objective:To explore the relationship between self-perceptions of aging and cognitive function, and the mediating and moderating effect of loneliness among them.Methods:A multi-stage stratified sampling was conducted in Jinzhou from September to November 2021, and 318 community-based elderly were included.General data questionnaire, the brief ageing perceptions questionnaire (BAPQ), UCLA loneliness scale(UCLA-LS) and mini-mental state examination (MMSE) were applied to all subjects.IBM SPSS 25.0 software was used to conduct independent sample t-test, analysis of variance and Pearson correlation analysis, and Bootstrap program of AMOS 22.0 was used to analyze the mediation effect.The model in SPSSAU on-line analysis program was used to test the moderating effect. Results:The average scores of self-perceptions of aging, loneliness and cognitive function were (44.85±12.48), (41.70±8.73) and (24.87±3.40) respectively.And 65 of 318 subjects had cognitive impairment, and the detection rate was 20.44%(65/318). Self-perceptions of aging, loneliness and cognitive function scores were significantly correlated between each other(all P<0.05). Self-perceptions of aging had a negative effect on cognitive function ( β=-0.467, P<0.01). Self-perceptions of aging had a positive effect on loneliness ( β=0.585, P<0.01). Loneliness had a negative effect on cognitive function ( β=-0.234, P<0.01). The indirect standardization effect of loneliness between self-perceptions of aging and cognitive function was -0.137, and the mediating effect accounted for 22.68% of the total effect.Loneliness played a moderating role between self-perceptions of aging and cognitive function ( β=-0.114, t=-2.26, P=0.025). Conclusion:Self-perceptions of aging and loneliness can predict the cognitive function in the elderly, and loneliness plays a mediating role between self-perceptions of aging and cognitive function.Early detection of negative senility emotion and loneliness of the elderly will play a positive role in preventing the occurrence of cognitive impairment.
