Multilevel analysis of sleep arrangements and psychological well-being among older couples in Taiwan.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThis study investigated the simultaneous associations between sleep arrangements (e.g., separate rooms for sleep) and psychological well-being (PWB) among older Taiwanese couples when considering individual and couple characteristics.
methodsThe study sample comprised 860 heterosexual married older couples (1,720 individuals) residing in Northern Taiwan. PWB was operationalized as a latent variable by three indicators: happiness, life satisfaction, and fulfillment. Sleep measures were assessed at individual and couple levels; a multi-level structural equation modeling (SEM) was employed, with couples at the level 2 unit and individuals at the level 1 unit.
resultsThe SEM results showed that older couples who slept in separate rooms experienced lower levels of PWB (β= - 0.12, p < .05) compared to those who slept together. In addition, a sensitivity analysis was also conducted, which controlled for previous relationship quality (e.g., conflict tactics), and the significant association between sleep in separate rooms and lower levels of PWB persisted (β= - 0.09, p < .01).
conclusionsSleep arrangement is a significant factor in a couple's PWB. The present investigation also underscored the importance of considering sleep within the context of a couple's relationship. Overall, the findings emphasize the need to consider the sleep arrangements of older couples when assessing their PWB.
