Depressive Disorders: Etiology01:27

Depressive Disorders: Etiology

Revisionist Views of Adolescent and Adult Cognition01:24

Revisionist Views of Adolescent and Adult Cognition

A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are themselves.

Self-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...

Erikson'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...
Modeling in Therapy01:26

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
Participant Modeling
Participant modeling involves therapists demonstrating calm and effective behaviors in situations...
Cognitive Development During Adolescence01:18

Cognitive 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...

Area of Science:

  • Psychology
  • Adolescent Health
  • Mental Health Research

Background:

  • Suicidal ideation is a significant risk factor for suicide attempts and completions.
  • Understanding the predictors of suicidal ideation in adolescents is crucial for effective prevention strategies.

Purpose of the Study:

  • To test a structural model explaining adolescent suicidal ideation.
  • To examine the relationships between trait anger, anger suppression, entrapment, psychosomatic symptoms, depression, resilience, and suicidal ideation.

Main Methods:

  • A large-scale study involving 11,393 students from middle and high schools in Korea.
  • Structural modeling was used to analyze the direct and indirect effects of predictor variables on suicidal ideation.

Main Results:

  • Trait anger, entrapment, psychosomatic symptoms, depression, and resilience directly impacted suicidal ideation.
  • Anger suppression indirectly influenced adolescent suicidal ideation.
  • The studied predictor variables explained 39% of the variance in suicidal ideation.

Conclusions:

  • Interventions aimed at preventing or alleviating adolescent suicidal ideation should focus on enhancing resilience.
  • Reducing anger, feelings of entrapment, psychosomatic symptoms, and depression are key targets for intervention.
