Multiple sclerosis (MS) entails various cognitive and psychological changes. The capacity to direct attention (CDA) is the ability to inhibit competing and distracting stimuli while processing information from the environment. A strong CDA is essential for effective functioning in daily life. The CDA may be reduced by MS lesions and by excessive attention-draining demands imposed by the disease. The purpose of this study was to assess CDA using a one-group descriptive correlational design. The sample consisted of 33 outpatients in symptom remission with relapsing-remitting MS who had virtually no physical disability. As theorized, the MS group presented with attentional deficits of varying severity, despite the presence of few physical symptoms. These deficits were unrelated to depressive symptoms. Findings indicate that nurses need to consider attentional problems even in the most early disease states. Further research is needed to better understand the impact of attentional deficits on daily life functioning and to develop nursing interventions for conservation or restoration of CDA in individuals with relapsing-remitting MS.
多发性硬化症（MS）会引发各种认知和心理变化。定向注意力（CDA）能力是指在处理来自环境的信息时抑制竞争性和干扰性刺激的能力。强大的CDA能力对于日常生活中的有效功能至关重要。MS病变以及该疾病带来的过度消耗注意力的需求可能会降低CDA能力。本研究的目的是采用单组描述性相关设计来评估CDA。样本包括33名处于症状缓解期的复发缓解型MS门诊患者，他们几乎没有身体残疾。正如理论推测的那样，尽管几乎没有身体症状，但MS组仍表现出不同程度的注意力缺陷。这些缺陷与抑郁症状无关。研究结果表明，即使在疾病的最早期阶段，护士也需要考虑注意力问题。需要进一步研究以更好地理解注意力缺陷对日常生活功能的影响，并为复发缓解型MS患者开发保护或恢复CDA的护理干预措施。
