ABSTRACT

Objective/Background

Illness severity and resultant dysfunction are often linearly related and tightly coupled (concordant). Some percentage of individuals, however, exhibit discordant associations (high illness severity and low dysfunction [HL] or low illness severity and high dysfunction [LH]). In the present study, a sample of subjects with insomnia complaints were evaluated to determine what percentage of subjects exhibited discordant associations.

Participants

Archival data were drawn from a community-based sample (n = 4,680; 61.8% female; Ages 18–105).

Methods

Median splits were calculated for illness severity and daytime dysfunction and each individual was typed as High (H) or Low (L) for the concordant (HH and LL) and discordant domains (HL and LH).

Results

Given this typology, 61% were classified as concordant and 39% were classified as discordant. Of these, 38% were sub-typed as HH, 23% as LL, 26% as LH, and 13% as HL.

Conclusions

We propose that some of the discordance may be ascribable to a mismatch between sleep need and sleep ability. Those “who need a lot, may suffer a lot, in the face of only a little (LH)”, whereas those “who need a little, may suffer only a little, in the face of a lot (HL)”.

失眠的严重程度和功能障碍的程度：当这些领域不一致时要学习什么？

摘要

目标/背景

疾病严重程度和由此产生的功能障碍通常呈线性相关且紧密耦合（一致）。然而，某些百分比的个体表现出不一致的关联（高疾病严重程度和低功能障碍 [HL] 或低疾病严重程度和高功能障碍 [LH]）。在本研究中，对有失眠症状的受试者样本进行了评估，以确定有多少百分比的受试者表现出不和谐的关联。

参与者

档案数据取自基于社区的样本（n = 4,680；61.8% 女性；18-105 岁）。

方法

计算疾病严重程度和日间功能障碍的中位数分裂，并将每个个体分类为一致（HH 和 LL）和不一致域（HL 和 LH）的高 (H) 或低 (L)。

结果

鉴于这种类型，61% 被归类为一致，39% 被归类为不一致。其中，38% 的亚型为 HH，23% 的亚型为 LL，26% 的亚型为 LH，13% 的亚型为 HL。

结论

我们提出，一些不一致可能归因于睡眠需求和睡眠能力之间的不匹配。那些“需要很多，可能会遭受很多，面对只有一点（LH）”的人，而那些“需要一点，可能只会遭受一点，面对很多（HL）”的人。
