Despite clinical observation that stroke survivors frequently experience loneliness, there is no large-scale empirical evidence to support this observation. Therefore, the primary objective of this research was to provide the first large-scale and comprehensive estimate of loneliness in the stroke survivor population.
To address this issue, we completed two preregistered analyses of a nationally representative annual survey (N > 21,000). A two-phase approach was adopted combining both exploratory (Study 1) and confirmatory (Study 2) phases. The benefit of such an approach is that replication is built into the design, which considerably strengthens the inferences that can be made.
Across two separate cohorts, the results consistently showed that human stroke survivors report higher levels of loneliness compared with healthy individuals, and this relationship could not be accounted for by demographic factors (e.g., age, sex) or objective measures of social isolation (e.g., marital status, number of household members).
These findings demonstrate that elevated levels of loneliness poststroke are robust in that they replicate in large nationally representative samples and cannot be reduced to objective measures of social isolation. The work has clinical and societal relevance by suggesting that loneliness poststroke is unlikely to be adequately "treated" if only the quantity and not the quality of social experiences are considered.
尽管临床观察到中风幸存者经常感到孤独,但没有大规模的实证证据支持这一观察结果。因此,本研究的主要目的是首次对中风幸存者群体中的孤独感进行大规模和全面的估计。
为了解决这个问题,我们对一项全国性年度调查(N>21000)进行了两项预先注册的分析。采用了一种两阶段的方法,结合了探索性(研究 1)和验证性(研究 2)阶段。这种方法的好处是,设计中内置了复制,这大大增强了可以得出的推论。
在两个独立的队列中,结果一致表明,与健康个体相比,中风幸存者报告的孤独感水平更高,而这种关系不能用人口统计学因素(如年龄、性别)或客观的社会隔离指标(如婚姻状况、家庭成员数量)来解释。
这些发现表明,中风后孤独感水平升高是稳健的,因为它们在大型全国代表性样本中得到了复制,并且不能归因于客观的社会隔离指标。这项工作具有临床和社会意义,因为如果只考虑社会体验的数量而不是质量,中风后孤独感不太可能得到充分的“治疗”。
