We examined the prevalence of depressive symptoms over time in a sample of community-residing older adults at baseline, 2 months, 6 months, and 14 months. The nonprobability sample (N = 222) was 90% female, 87% Caucasian, 15% Hispanic, and 12% African American with an average age of 75 years. If depressive symptoms had been measured at only one time, 19% of the sample would have scored above the cutoff versus 39% scoring above the cutoff when measured at all 4 periods. The findings provide evidence that depressive symptoms in older adults are variable and fluctuate over time. The significance of this research was the longitudinal evaluation of depressive symptoms in community-residing elders.
我们在基线、2 个月、6 个月和 14 个月时,对一个社区居住的老年人群体样本进行了抑郁症状随时间变化的患病率研究。该非概率样本(N=222)中 90%为女性,87%为白种人,15%为西班牙裔,12%为非裔美国人,平均年龄为 75 岁。如果仅在一个时间点测量抑郁症状,那么有 19%的样本得分高于临界值,而在所有 4 个时间段测量时,有 39%的样本得分高于临界值。研究结果表明,老年人的抑郁症状是多变的,且随时间波动。这项研究的意义在于对社区居住的老年人抑郁症状进行了纵向评估。
