Nightmares and Night Terrors01:18

Nightmares and Night Terrors

82
Nightmares and night terrors represent two distinct types of sleep disturbances that differ in timing, characteristics, and the sleeper's recall of the event. Nightmares are vivid, disturbing dreams that usually awaken the sleeper from REM sleep, a stage of sleep where brain activity is high, and dreams are most frequent. Upon awakening, individuals often have detailed recollections of their nightmares, which can include themes of threats to survival, security, or self-esteem.

Lazarus's Cognitive Appraisal Theory01:20

Lazarus's Cognitive Appraisal Theory

200
Cognitive psychologist Richard Lazarus proposed the cognitive-mediational theory of emotions, which emphasizes how individuals' assessments of stressors significantly affect their experience of stress. According to Lazarus, the stress response is determined by a two-step appraisal process: primary appraisal and secondary appraisal. These cognitive appraisals help individuals evaluate the potential impact of a stressor and determine the adequacy of their coping resources.
Primary Appraisal:...

REM Sleep Behavior Disorder01:15

REM Sleep Behavior Disorder

163
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Psychological Responses to Stress01:20

Psychological Responses to Stress

50
Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...

Beck's Cognitive Therapy

39
Cognitive therapy is a psychological approach designed to address distortions in thinking, which can lead to negative emotions and unrealistic beliefs. These cognitive distortions often influence how individuals interpret and respond to situations, exacerbating emotional distress. Below are some prevalent cognitive distortions, their characteristics, and examples of how they manifest in thought processes.

Rational Emotive Behavior Therapy01:24

Rational Emotive Behavior Therapy

47
Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert...

Summary

Neuroticism contributes to nightmare distress, with rumination partially mediating this link. Interventions targeting repetitive negative thoughts may help individuals with high neuroticism manage nightmares, regardless of sex.

Area of Science:

  • Psychology
  • Sleep Science
  • Clinical Psychology

Background:

  • Neuroticism is linked to nightmare distress.
  • Negative coping styles may mediate this relationship.
  • The interaction between neuroticism, rumination, and nightmare distress requires further investigation.

Purpose of the Study:

  • To investigate the roles of neuroticism and ruminative response in nightmare distress.
  • To explore the mediating effect of rumination on the neuroticism-nightmare distress relationship.
  • To examine potential sex differences in this relationship.

Main Methods:

  • Recruited 758 university students (average age 19.07).
  • Employed a moderated mediation model using SPSS PROCESS 3.5.
  • Assessed neuroticism, rumination, and nightmare distress (dream anxiety scale).

Main Results:

  • Rumination partially mediated the relationship between neuroticism and dream anxiety (β=0.32).
  • Rumination also mediated the association between dream anxiety and sleep disturbances (β=0.11) and daytime dysfunctions (β=0.21).
  • Sex did not significantly moderate the path from neuroticism to dream anxiety.

Conclusions:

  • Rumination acts as a partial mediator between neuroticism and nightmare distress.
  • Interventions focusing on repetitive negative thinking may alleviate nightmares in high-neuroticism individuals.
  • Sex differences were not significant in the studied pathways.
