How Sleep Quality, Body Clock Type, and Social Jetlag Relate to Stress in Irish Adults

An observational study of 400 Irish adults found moderate associations between subjective sleep quality and perceived psychological stress.

• Statistically significant associations were observed between social jetlag, mid-sleep on free days, and perceived stress, though the effects were small.
• Individuals experiencing high perceived stress reported greater social jetlag and poorer sleep quality compared to those with low or moderate stress, with no differences in chronotype.
• A moderate reciprocal relationship exists between subjective sleep quality and perceived stress.
• Chronotype and social jetlag appear to have minimal relationships with perceived stress.
• Average nightly sleep duration showed a small indirect effect on perceived stress, mediated by subjective sleep quality.
