Background:
- Loneliness is a prevalent issue impacting mental and physical health.

- To investigate the link between an individual's loneliness and their partner's sleep quality.
- To test stress as a mediator in the relationship between loneliness and sleep quality.
Main Methods:
- Cross-sectional study design.
- 255 couples (married or cohabiting) completed self-report questionnaires.

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required.
