Association of temperament with subjective sleep patterns

Area of Science:

• Psychiatry
• Sleep Medicine
• Psychology

Background:

• Sleep disturbances are closely linked to psychiatric disorders and personality traits.
• Emotional and cognitive functioning play a role in insomnia etiology.
• This study explores the connection between temperament and subjective sleep quality.

Purpose of the Study:

• To investigate the association between emotional and affective temperaments and subjective sleep parameters.
• To understand how different temperament profiles relate to sleep onset latency, awakenings, and overall sleep quality.
• To examine the sleep characteristics of individuals with specific affective temperaments.

Main Methods:

• A web-survey of 5129 participants assessing temperament using the Combined Emotional and Affective Temperament Scale (CEATS).
• Participants also reported on subjective sleep parameters, psychiatric diagnoses, and medication use.
• CEATS measures emotional temperaments (fear, anger, drive, control) and affective temperaments (cyclothymic, hyperthymic).

Main Results:

• Lower control scores correlated with later bedtimes and wake times.
• Higher anger and lower control scores were associated with increased sleep-onset latency and nightly awakenings.
• Higher drive and control, with lower anger, predicted better sleep quality.
• Depressive, labile, and cyclothymic temperaments were linked to later sleep schedules and poorer sleep, while hyperthymic and euthymic temperaments showed favorable sleep profiles.

Conclusions:

• Dysregulated emotional activation (high anger, low control/drive) is associated with dysfunctional sleep patterns.
• Specific affective temperaments (depressive, labile, cyclothymic) are related to negative sleep outcomes.
• Temperament is a significant factor influencing subjective sleep quality and patterns.
