In Personality

Is your personality linked to your sleep quality?

Those of you who are following publications on the Stress-n-Health corner FB are already familiar with personality traits that constitute the Big Five model. These personality characteristics (Extraversion, Neuroticism, Conscientiousness, Openness, and Agreeableness) have been investigating as predictors of sleep quality. The study published in Health Psychology  examined more than 22,000 adults aged 30 to 107. Personality and sleep quality were assessed in the beginning of the study (baseline) and then again 4 to 10 years later.

The researchers found that scoring lower on Neuroticism and higher on Extraversion was associated with better sleep quality at baseline and over time.

Low scores on Conscientiousness was associated with a worsening of sleep quality over time.

Openness and Agreeableness were unrelated to sleep quality.

Poor sleep quality at baseline was associated with steeper declines in Extraversion, Agreeableness, and Conscientiousness and a smaller decrease in Neuroticism over time.
