Summary
Sleep problems in early adolescence significantly predict later suicidal thoughts and self-harm behaviors, even when accounting for depression. Vigilance and screening for sleep disturbances are crucial for identifying at-risk youth.
Area of Science:
- Adolescent psychology
- Sleep science
- Public health
Background:
- Previous research indicates a link between sleep issues and suicidal behavior.
- The extent to which depression explains this association remains unclear.
Purpose of the Study:
- To prospectively examine the relationship between adolescent sleep problems and subsequent suicidal thoughts and self-harm.
- To determine if sleep problems predict suicidality independently of depressive symptoms.
Main Methods:
- A longitudinal study followed 392 adolescents (280 boys, 112 girls) from high-risk and control families.
- Sleep problems, depressive symptoms, and suicidal behaviors were assessed at ages 12-14 and 15-17.
Main Results:
- Trouble sleeping at ages 12-14 significantly predicted suicidal thoughts and self-harm behaviors at ages 15-17.
- This association remained significant after controlling for gender, parental factors, and prior suicidal ideation.
- Depressive symptoms, nightmares, aggressive behavior, and substance use were not significant predictors in the final model.
Conclusions:
- Sleep problems are a strong predictor of adolescent suicidal thoughts and self-harm behaviors.
- Sleep disturbances may serve as an early marker for suicidality.
- Parents and physicians should screen adolescents for sleep problems to identify those at risk.

01:18Cognitive Development During Adolescence
During adolescence, individuals experience significant cognitive development that enhances their understanding of others' emotions and thoughts, known as cognitive empathy. This period is marked by an increased ability to adapt to others' perspectives and a more nuanced understanding of others' mental states, a skill that is foundational for social problem-solving and conflict avoidance. The development of cognitive empathy relies heavily on the theory of mind — the recognition that people have...
03:00Self-Evaluation: Self-Enhancement and Self-Verification
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
01:13Insufficient 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.

01:18Sources of Self-Esteem I: Family Experience
Self-esteem, a crucial component of psychological development, is significantly shaped by familial experiences. The early parent-child relationship serves as a foundational influence on a child's self-concept, with long-lasting effects extending into adolescence and adulthood.Parental Behaviors and Early Self-Esteem FormationEmpirical studies have identified four principal parental behaviors that foster healthy self-esteem in children. These include expressions of acceptance, affection, and...
01:17Erikson's Theory on Socioemotional Development during Adolescence
Erik Erikson's fifth stage of psychosocial development, "identity versus role confusion," is crucial during adolescence (ages 12 to 18). In this stage, adolescents face the developmental task of forging a distinct personal identity, a process influenced by social, psychological, and biological changes typical of this period. Adolescents naturally explore different roles, behaviors, and ideologies as they navigate complex questions of self-concept, asking, "Who am I?" and "What is my place in...
01:27Ethnic Identity within a Larger Culture
Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...
