Direct and Moderating Causal Effects of Network Support on Sleep Quality: Findings From the UC Berkeley Social...

Area of Science:

• Psychology
• Sociology
• Sleep Science

Background:

• Sleep quality is crucial for health, yet many adults experience sleep disturbances.
• Personal support networks may improve sleep and mitigate stress, but longitudinal research is limited.

Purpose of the Study:

• To investigate the causal impact of personal network support changes on sleep quality.
• To examine direct effects and the buffering role of support against negative life events in young and older adults.

Main Methods:

• Utilized data from the UC Berkeley Social Network survey (2015-2018).
• Analyzed three waves of data from young (21-30) and older (50-70) adults.
• Employed fixed effects models to assess causal relationships within age cohorts.

Main Results:

• Older adults: Insufficient practical support increased trouble falling asleep (IRR=1.40). More social companions decreased trouble staying asleep (IRR=0.81).
• Young adults: Partnership changes buffered the impact of losing a loved one on falling asleep (IRR=0.75) and financial stress on staying asleep (IRR=0.45).

Conclusions:

• Personal networks play a direct role in sleep quality for older adults and a buffering role for younger adults.
• Interventions to improve sleep should consider the influence of social support, particularly for young adults facing stress.
