ABSTRACT
<p><b>OBJECTIVE</b>To introduce the Item Function Analysis(IFA) of Quality of Life- Alzheimer's disease(QOL-AD)Chinese version and to explore the feasibility of its application on Chinese patients with AD.</p><p><b>METHODS</b>Two hundred AD patients were interviewed and assessed by QOL-AD, through the stratified cluster sampling method. Multilog 7.03. was used for Item Function Analysis. Difference scale(a), difficulty scale(b)and Item Characteristic Curve(ICC) of each item of QOL-AD were provided.</p><p><b>RESULTS</b>Different scales of the item 1, 7 were below 0.6, while all the others were above 0.6. As for ICC. The first and last lines for the other items were monotonic in which the two in between were in inverted V-shape, with very steep slopes, except for the item 1 and 7.</p><p><b>CONCLUSION</b>Results form the IFA showed that QOL-AD was applicable to be used in the Chinese patients with AD.</p>

Objective To investigate the current status and influencing factors regarding quality of life among patients with Alzheimer' s disease (AD).Methods Through stratified cluster sampling method,two hundred patients with AD and their caregivers were chosen and interviewed.AD patients were assessed by questionnaires,Montreal Cognitive Assessment,and Quality of LifeAlzheimer' s Disease (QOL-AD),in order to compare the reports from patients and caregivers on QOL-AD and to analyze related influencing factors.Descriptive analysis,paired t-test,analysis of variance (ANOVA),Pearson' s correlation and multiple linear regression were performed using the Statistical Package for Social Science (SPSS).Results The scores of reports from patients (28.78 ±4.30) were lower than that from the caregivers' (30.05 ± 6.05).The difference was statistically significant (t=2.122,P＜0.05) and was positively correlated (r=0.312,P＜0.001).Data from multivariate analysis showed that cognitive level (t=3.465,P=0.001),marriage relationship (t=3.062,P=0.003 ),having public activities (t =2.581,P=0.011 ),personal characters (t =2.254,P =0.026),restricted diet pattern (t=3.614,P＜0.001),regularly drinking tea (t=2.652,P=0.009) and doing housework (t=3.180,P=0.002) were predictive factors.Conclusion Scores from the caregiver' s report on QOL-AD were higher than that from the patients'.Many factors influenced the quality of life on AD patients.Strategies on improving the quality of life among AD patients can be developed based on the findings of this study.
ABSTRACT
Objective To explore the determinants of Alzheimer' s disease (AD) patients with depression.Methods The degree of depression on AD patients was assessed by the geriatric depression scale.Improved cumulative logistic regression (ICLR) was used to analyze the determinants of AD patients with depression.Results 196 AD patients were investigated.Among the 196 AD patients,there were 60(30.6％ ) males and 136(69.4％ ) females,at 58-89 years of age (72.3 ± 6.0).Physical activity,diabetes,MoCA,hearing,economic sources and alcohol were related to the degree of depression of AD patients (P＜0.10 ).The difference between “normal” and “mild depression” was smaller than difference between “mild depression” and “severe depression”.Conclusion AD patients with mild depression were the target population for prevention and they were influenced by several factors listed above.
