目的：使用一种创新的统计方法--潜在类轨迹分析，在全国范围内为患有dementia.DESIGN:Longitudinal.SETTING:Community.PARTICIPANTS:Respondents的丈夫提供非正式护理的妻子样本中识别和描述照顾者抑郁症状的亚组(称为轨迹)。国家纵向照顾者调查是指通过全国退伍军人事务医院确认的退伍军人痴呆症的妻子照顾者。测量：使用流行病学研究中心抑郁量表(CES-D，20个条目量表)测量的抑郁症状的平均数量。结果：妻子照顾者的总体平均抑郁症状为6.2/20，低于临床抑郁症的分界点(8或9/20)。确定了照顾者抑郁症状的四种不同轨迹。症状数量最多的轨迹(20个中的11.9个)包含三分之一的样本。另有三分之一的人抑郁症状的平均值与总体样本平均值几乎相同。最后三分之一被分为两个轨迹，低抑郁症状(CES-D平均，3.0/20，样本的22%)和非常低(CES-D的平均，0.8/20，样本的14%)。大约三分之二的样本成员处于抑郁症状轨迹中，症状数量明显高于或低于总体平均值。询问妻子照顾者的两项主观测量(渴望更多帮助、生活满意度)与最高抑郁症状轨迹的成员身份显著相关。结论：LCTA确定了妻子照顾者的重要抑郁症状亚组。人口平均法确定的平均效应与三分之一的病例相似，但与三分之二的病例显著不同。
OBJECTIVES:To use an innovative statistical method, Latent Class Trajectory Analysis (LCTA), to identify and describe subgroups (called trajectories) of caregiver depressive symptoms in a national sample of wives providing informal care for their husbands with dementia.DESIGN:Longitudinal.SETTING:Community.PARTICIPANTS:Respondents to the National Longitudinal Caregiver Survey were wife caregivers of veterans with dementia who were identified through Veterans Affairs hospitals nationally.MEASUREMENTS:Mean number of depressive symptoms as measured using the Center for Epidemiologic Studies Depression scale (CES‐D, 20‐item scale).RESULTS:Overall mean depressive symptoms of wife caregivers were 6.2 of 20, below the cutpoint (8 or 9/20) associated with clinical depression. Four distinct trajectories of caregiver depressive symptoms were identified. The trajectory with the highest number of symptoms (11.9 of 20), contained one‐third of the sample. Another third had mean depressive symptoms virtually identical to the overall sample mean. The final third were divided between two trajectories, low depressive symptoms (mean CES‐D, 3.0/20, 22% of sample) and very low (mean CES‐D, 0.8/20, 14% of sample). Approximately two‐thirds of the sample members were in a depressive symptom trajectory, with substantially higher or lower numbers of symptoms than the overall mean. Two subjective measures asked of wife caregivers (desire for more help, life satisfaction) were significantly associated with membership in the highest depressive symptom trajectory.CONCLUSION:LCTA identified important depressive symptom subgroups of wife caregivers. A population‐averaging method identified a mean effect that was similar to the effect in one‐third of the cases but substantially different from that in two‐thirds of the cases.
