| Objective1、To establish a Chinese version of illness perception questionnaire-memory(IPQ-M)on the base of cross-culture adaption and evaluation of psychometric properties of the studied questionnaire.2、To study the illness perception feature of subjective memory complaints(SMCs)as well as the influence factors by using a cross-sectional survey,aiming to help community health worker and elderly medical researchers have a better understanding about the feature of illness perception-memory of the SMCs adults,so as to provide them with better medical services and targeted health intervention.3、By studying the impact of illness perception-memory on help-seeking behavior in adults with subjective memory complaints(SMCs),to provide theoretical basis for the establishment of targeted health education and intervention measures.Besides to promote adults with SMCs to seek help as early as possible.Method1、The introducing of the illness perception questionnaire-memory was performed following the standard process of “translation-back translation-cultural adjustmentpreliminary test-field test”,and modified through expert consultation method and preliminary test.2、Researcher and her companion conduct a survey on 660 adults with subjective memory complaints who were accorded with the inclusive criteria from 4 communities of Chongqing by sampling conveniently.The data was divided into equal two parts by parity binary method.One part was sample A(n=330),which was used to exploratory factor analysis.The other part is sample B(n=330),which was used to confirma tory factor analysis by AMOS 20.0 software.The data of sample B were analyzed to reevaluate the internal reliability,test-retest reliability,split-half reliability,criterion-related validity.3、A total of 305 subjective memory complaints adults who were accorded with the inclusive criteria completed the illness perception questionnaire-memory of Chinese version.One-way analysis of variance,spearman correlation and multiple linear regressions were used to analysis the illness perception feature of subj ective memory complaints(SMCs)as well as the influence factors.4、Subjects were investigated with illness perception questionnaire-memory(IPQ-M)、GDS、mini-mental state examination(MMSE)、auditory verbal learning test(AVLT).To study the impact of illness perception-memory on help-seeking behavior in adults with SMCs by logistic regression analysis.Results1、Psychometric properties of the questionnaireThe Chinese version IPQ-M comprised of 86 items,3 aspects,11 dimensions.The first part is the feature dimension,including 19 symptoms.The symptoms associated with memory decline entry accumulative score as symptoms perception score.Higher scores show that the more symptoms of perception.The second part is the illness cognition,including 44 items.The second part is composed 9 dimensions,including: timeline acute/chronic,consequences,timeline stability/decline,personal control(blame),personal control(helplessness),emotional representation,treatment control,illness coherence,social comparison.The third part is the disease attribution dimension,including 23 items SMCs adults may think that the cause of memory decline.The results of psychometric tests are the following:(1)Content validity index(CVI):The I-CVI of Chinese version IPQ-M was 0.83~1.0,the S-CVI was 0.913.(2)Construct validity:The results of principal components factor analysis showed the questionnaire with cumulative contribution rate of variance was 70.757%.The loading of each item on the corresponding factors was higher than 0.4.The results of confirmatory factor analysis further proved the construct of Chinese version questionnaire with X2/df=1.865,RMR=0.027,RMSEA=0.075,GFI=0.940,AGFI=0.910,NFI=0.903,CFI=0.939。(3)Criterion-related validity: The correlation between Chinese version of IPQ-M and GDS were-0.242~0.614(p<0.05).(4)Internal reliability:The Cronbach’s a coefficient of the questionnaire was ranged from 0.770 to 0.927.(5)Test-retest reliability:The test-retest reliability was ranged from 0.532 to 0.908.(6)Split-half reliability:The Spearman-Brown split coefficient was ranged from 0.747 to 0.916.2、The perception feature and the influence factors of middle aged and old with subjective memory complaints(SMCs).The average score of 9 subscales for the second part of perception questionnaire were listed as follows: timeline acute/chronic(3.57±0.89),consequences(2.24±0.77),timeline stability/decline(3.71±0.88),personal control(blame)(3.61±0.92),personal control(helplessness)(3.31±0.73),emotional representation(2.29±0.70),treatment control(2.78±0.67),illness coherence(3.14±0.64),social comparison(2.95±0.78).Compared with median three points,in addition to the social comparison dimension the difference was not statistically significant,the oth er dimension have statistical significance.For memory decline attribution,score the top five is in turn: aging(93.5%),lack of concentration/not listening properly(75.4%),lack of blood to the brain(61.1%),not using my brain(58.4%),loss of brain cells(55.9%).In addition,31.1% of people attribute the cause of memory decline to bad chance or luck.The perception of SMCs were affected by sex、education degree、living condition、marital status、economic level、family history of dementia and dementia education.3、Impact of illness perception-memory on help-seeking behavior.The ratio of SMCs people for help-seeking is very low in the region,only 14.4%.Among this,the ratio for seeking advice to community health service center is 5.6%.The ratio for asking friends and relatives is 5.2%.The ratio for watching the health programs and books is 1.6%.The ratio for going to hospital to see a specialist memory clinic accounted for only 2.0%.By logistic regression analysis,9 related factors were associated with the decision to seek help for SMCs,which were identity(OR=1.455),treatment control(OR=2.456),emotional representation(OR=2.268),acceptingdementia education(OR=5.176),lacking of blood supply to the brain(OR=1.115),not using brain(OR=2.079),aging(0.450),loneliness(0.253),chance or bad luck(OR=0.374).Conclusions1、The Chinese version of IPQ-M has good reliability and validity,and can be used in Chinese middle aged and elderly people with SMCs.2、The people with SMCs had poor understanding of the knowledge about memory decline.They had some negative and error views about the perceptions of SMCs.The influence factors about the perceptions are complex.So some targeted strategies should be formulated,in order to improve their knowledge about memory decline and dementia prevention and cultivate positive and correct perception.3 、 Illness perception about memory predict help-seeking behavior.The way of help-seeking is very single.The medical staff in community should attach importance to the illness perception-memory of SMCs people and promote them help-seeking early,so as to facilitate the early screening,identification and prevention of dementia. |
