Alzheimer's disease is one of the debilitating chronic diseases among older persons. It is an irreversible condition that leads to progressive deterioration of cognitive, intellectual, physical, and psychosocial functions. The study was aimed to assess the knowledge of the family members of elderly regarding Alzheimer's disease in a selected urban community at Mangalore.
A preexperimental research design of one group pretest and posttest with an evaluative approach was adopted for the study. A total of 50 family members of elderly who met the inclusion criteria were selected through purposive sampling technique. The researcher developed a planned teaching program on Alzheimer's disease, and structured knowledge questionnaire on Alzheimer's disease was used to collect the data.
Descriptive and inferential statistics was used to analyze the data. Analysis revealed that the mean posttest knowledge (20.78 ± 3.31) was higher than mean pretest knowledge scores (12.90 ± 2.43). Significance of difference between pretest and posttest was statistically tested using paired "t" test and it was found very highly significant (t = 40.85, P < 0.05). Majority of the variables showed no significant association between pretest and posttest knowledge score and with demographic variables.
The findings revealed that the planned teaching program is an effective strategy for improving the knowledge of the subjects.
阿尔茨海默病是老年人中使人衰弱的慢性疾病之一。它是一种不可逆的病症，会导致认知、智力、身体和心理社会功能逐渐衰退。本研究旨在评估芒格洛尔一个选定城市社区中老年人家庭成员对阿尔茨海默病的了解情况。
本研究采用一组前测和后测的实验前研究设计，并采用评估方法。通过目的抽样技术，共选取了50名符合纳入标准的老年人家庭成员。研究人员制定了一个关于阿尔茨海默病的计划教学方案，并使用关于阿尔茨海默病的结构化知识问卷来收集数据。
使用描述性和推断性统计分析数据。分析表明，后测知识的平均得分（20.78 ± 3.31）高于前测知识得分的平均值（12.90 ± 2.43）。使用配对“t”检验对前测和后测之间差异的显著性进行统计检验，发现差异非常显著（t = 40.85，P < 0.05）。大多数变量在前测和后测知识得分与人口统计学变量之间未显示出显著关联。
研究结果表明，计划教学方案是提高受试者知识水平的有效策略。
