Insomnia

490
Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.

The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

Social Relationships and Well-Being

322
The significance of social relationships in psychological well-being is a well-established area of inquiry within social psychology. Research consistently demonstrates that the presence of meaningful, supportive relationships enhances emotional health, while the absence or deterioration of such connections can contribute to psychological distress. Relationships serve as a foundation for emotional support, identity, and social belonging, all of which are critical to an individual’s overall...

Area of Science:

  • Psychology
  • Sleep Medicine
  • Personality Science

Background:

  • Type D personality combines negative affectivity and social inhibition.
  • Previous research suggests a link between Type D personality and sleep disturbances in adolescents.

Purpose of the Study:

  • To investigate the relationship between Type D personality and insomnia symptoms in a general population sample.
  • To determine the specific contributions of negative affectivity and social inhibition to insomnia.

Main Methods:

  • A general population sample of 392 adults completed online questionnaires.
  • Measures included the DS14 for Type D personality and a validated insomnia severity scale.

Main Results:

  • Type D individuals reported significantly higher insomnia symptoms compared to Non-Type D individuals.
  • Negative affectivity was a significant independent predictor of insomnia symptoms, even after controlling for social inhibition and the Type D interaction.

Conclusions:

  • Type D personality is associated with insomnia symptoms, both categorically and dimensionally.
  • Negative affectivity is the key component of Type D personality contributing to insomnia.
