The purpose of the study was to explore the impact of change in functional limitation (FL), controlling for social support (SS), on attitudes toward aging using longitudinal survey data collected over a 7-year period. The 503 women with multiple sclerosis (MS; age, M=57 years, SD=10.25) were mostly Anglo (93%) and married (69%). First, the authors identified a quadratic growth model as the best for describing change in FL. Next, they considered SS as a time-varying covariate of FL to assess both within- and between-individual effects of SS on FL over time. Within individuals, higher FL levels were associated with lower SS levels. Between individuals, level of but not change in FL was associated with average SS level. Finally, average SS and response level and change in FL were studied as predictors of attitudes toward aging, accounting for 38% of the variance. Women with higher FL and lower SS scores had more negative views of aging. Negative views of aging among women with MS may have long-term consequences for their health outcomes as well as for the quality of their later years.
本研究的目的是利用7年期间收集的纵向调查数据，探讨功能受限（FL）变化在控制社会支持（SS）的情况下对衰老态度的影响。503名患有多发性硬化症（MS；年龄，M = 57岁，标准差 = 10.25）的女性大多为盎格鲁人（93%）且已婚（69%）。首先，作者确定二次增长模型最适合描述FL的变化。接下来，他们将SS视为FL的随时间变化的协变量，以评估SS随时间对FL的个体内和个体间效应。在个体内部，较高的FL水平与较低的SS水平相关。在个体之间，FL的水平而非变化与平均SS水平相关。最后，研究平均SS和反应水平以及FL的变化作为衰老态度的预测因素，它们解释了38%的方差。FL较高且SS得分较低的女性对衰老的看法更消极。患有MS的女性对衰老的消极看法可能会对她们的健康结果以及晚年生活质量产生长期影响。
