USE OF MICROCOMPUTERS TO STUDY BEHAVIORAL SYMPTOMS

这项提议的主要目标是利用微型计算机技术 实时记录行为障碍和环境事件 这可能与这些骚乱有关。直接观测将是 在四家疗养院分别密集和连续地进行，以及 将在两年内在养老院中顺序重复 一段时间。认知和日常生活能力状况的标准化评估，如 以及对药物与健康探索性措施的评估 状态/生活事件也将在每个观测时期重复发生 两年多了。它有三个具体目标：(1)基于直接 观察，我们将报告发生的比率和持续时间 身体攻击，言语干扰，以及步态/焦躁不安。费率和 持续时间将与最初的认知和ADL测量进行比较 现状，以及探索性措施。分析将基于 136年第一个完整观测纪元的横截面样本 居民；(2)基于相同的横断面数据库，我们将审查 环境因素与行为的关系 症状学通过使用滞后序贯分析。影响 关于这些关系的认知、ADL、药物和健康状况 (3)我们会对 个人居民行为症状发生率和持续时间超过一年 最多两年。这一分析的重点将放在 行为改变与认知和日常生活能力改变的关系 现状，探索性措施的变化。本项目的成果 将用于开发环境/行为干预措施 DAT的行为并发症。

The major goal of this proposal is to utilize microcomputer technology for real-time recording of behavioral disturbances and environmental events that may be related to these disturbances. Direct observations will be conducted intensively and consecutively in each of four nursing homes, and will be repeated sequentially among the nursing homes over a two year period of time. Standardized assessments of cognitive and ADL status, as well as evaluations on exploratory measures of medication and health status/life events will also be repeated during each observational epoch over two years. There are three specific aims: (1) based on direct observations, we will report the rate of occurrence and duration of physical aggression, verbal disruption, and pacing/restlessness. Rate and duration will be compared with initial measures of cognitive and ADL status, and the exploratory measures. Analysis will be based on a cross-sectional sample of the first complete observational epoch for 136 residents; (2) based on the same cross-sectional data base, we will examine the relationship between environmental factors and behavioral symptomatology through the use of lag sequential analysis. The influence of cognitive, ADL, medication, and health status on these relationships will also be assessed; (3) we will conduct a longitudinal analysis of the rate and duration of individual resident behavioral symptomatology over a maximum of two years. The focus of this analysis will be on the relationship between change in behavior and changes in cognitive and ADL status, and changes on the exploratory measures. Results of this project will be used to develop environmental/behavioral interventions for the behavioral complications of DAT.
