The Relationship Between Coping And Adaption Ability And Episodic Memory And The Mediating Role Of Healthy Lifestyle In Adults With Subjective Memory Complaints

Objective:Based on the Roy adaption model,the study aimed to explore the association between coping and adaption ability and episodic memory in adults with Subjective Memory Complaints(SMCs),and to investigate the multiple mediation effect of six dimensions of healthy lifestyle between the relationships,so as to provide a feasible intervention for delaying the decline of cognitive function,which is of great significance for the prevention of Alzheimer’s disease.Method:This study is mainly divided into two stages: establish a Chinese version of coping andadaption processing scale(CAPS-15)and cross-sectional survey.1.Translate and culture the CAPS-15,and test the reliability and validity of the scale among 500 community-dwelling residents.The data was used to content validity,structure validity,criterion-related validity,internal reliability,test-retest reliability and split-half reliability to test the reliability and validity of the scale.2.The Chinese Coping and Adaption Processing Scale(CAPS-15),the Healthy Promotion Lifestyle Profile-II Revise(HPLP-IIR),and the Auditory Verbal Learning Test(AVLT)were used to evaluate the coping and adaption ability,healthy lifestyle and episodic memory of 309 adults with SMCs in community who met the exclusion criteria.The SPSS19.0 statistical software package was used to analyze the data.Descriptive statistical analysis was used to analyze the general demographic data of adults with SMCs who met the exclusion criteria.Independent sample T test,ANOVA test were used to analyze the episodic memory feature of adults with SMCs;Pearson correlation was applied to measure the correlations among episodic memory,coping and adaption ability,and healthy lifestyle;The multiple mediation effects of the healthy lifestyle was tested by using the hierarchical regression and Bootstrap method.Results:1.The Chinese version of Coping and Adaption Processing Scale(CAPS-15)is a simple dimensional scale with 15 items.The higher the score,the higher the individual’s coping and adaption ability.The reliability and validity of the scale are as follows:(1)Content validity index(CVI):The Content validity index of Chinese version CAPS-15 was ranged from 0.83 to 1.0,and the average content validity index was 0.92.(2)Construct validity:Exploratory factor analysis showed that the cumulative variance contribution rate of factors in the Chinese version of CAPS-15 was 52.302%.and each item had a satisfactory factor load(>0.4)on the corresponding factors.(3)Criterion-related validity:With Simplified Coping Style Questionnaire(SCSQ)as the calibration,the Chinese version of CAPS-15 and SCSQ showed a certain degree of correlation,the correlation coefficient was 0.558(P<0.01).(4)Internal reliability:The Cronbach’s alpha coefficient of Chinese version CAPS-15 was 0.815.(5)Test-retest reliability:The test-retest reliability was ranged from 0.834~0.990(P<0.05).2.A total of 309 community-dwelling adults with subjective memory complaints were recruited from Chongqing China.The average scores of AVLT was 26.47±8.53,T-test and Anova-analysis showed significant differences with AVLT scores on gender,age and educational years,more specifically,adults with subjective memory complaints who were female(t=0.278,P=0.020),the age group from 50 to 54(F=2.864,P=0.010),the educational year over 12 years(F=12.075,P=0.000)had greater AVLT scores than those who were male,the other age groups and other educational years.Pearson correlation analysis indicated that coping and adaption ability were positively related to AVLT(P<0.01)and healthy lifestyle(P<0.01)respectively,and healthy lifestyle was positively related to AVLT(P<0.01).The overall effect of multiple mediation was significant,account for 49.11% of the total effect,and the coping and adaption ability of adults with subjective memory complaints has significant predictive effect on episodic memory(β=0.298,P=0.000).As for the multiple mediation effects,the mediation effect of healthy responsibility,nutrition and interpersonal relations was significant,while the exercise,interpersonal relations,stress management,spiritual growth was not.Their mediation effect account for 18.13%,16.75%,10.14%.Conclusion:1.The Chinese CAPS-15 has been proved to be reliable and valid.It can be used as a valid tool for measurement of the ability of the crowd.2.The coping and adaption ability of adults with subjective memory complaints has a significant predictive effect on episodic memory.Healthy responsibility,nutrition and interpersonal relationships of healthy lifestyle mediated the relationship between coping and adaption ability and episodic memory among adults with subjective memory complaints.
