Emerging Adulthood

Emerging Adulthood

Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

Substance Use Disorders Affecting Sleep

Substance Use Disorders Affecting Sleep

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Insufficient Sleep and Sleep Deprivation

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder

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...

Traits and States

Traits and States

Personality traits represent consistent patterns in behavior, thoughts, and emotions, reflecting an individual's tendencies across various situations. For example, extraversion, a well-known trait, manifests in individuals as talkative, energetic, and enthusiastic behaviors. These traits are stable over time, offering a reliable framework for predicting how people might act in different contexts. However, they do not define every moment of an individual's life. In contrast to traits,...

Socioemotional Development during Infancy

Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.

Area of Science:

Psychology

Clinical Psychology

Background:

Sleep disruption is associated with internalizing and externalizing disorders.
Previous research supports a link between psychopathology and sleep disturbances.

Purpose of the Study:

To investigate the relationship between sleep, impulsivity, antisocial personality traits, and internalizing traits in a university sample.
To extend existing research on sleep and psychopathology to a young adult population.

Main Methods:

386 university students (18-27 years) wore actigraphs for 7 days.
Participants completed validated questionnaires: Personality Assessment Inventory (PAI), Triarchic Psychopathy Measure, Barratt Impulsiveness Scale-11, and Pittsburgh Sleep Quality Index.
Analyses included correlational, bidirectional, and moderation analyses examining sleep, personality, and psychopathology.

Main Results:

Higher impulsivity predicted poorer subjective sleep quality in both sexes.
Elevated depression levels predicted poorer subjective sleep quality.
Improved sleep efficiency was associated with decreased depression.
Gender moderated sleep efficiency, with marginal effects observed.

Conclusions:

Findings in a university sample reinforce the link between sleep disturbances and psychopathology.
Impulsivity and depression are significant predictors of poor sleep quality in young adults.
Sleep quality may play a role in the development of psychopathology during young adulthood.
