Modeling in Therapy01:26

Modeling in Therapy

56
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.

Cognitive Development During Adolescence

47
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...

Erikson's Theory on Socioemotional Development during Adolescence

75
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...

Self-Evaluation: Self-Enhancement and Self-Verification

5.2K
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...

Conduct Disorder01:28

Conduct Disorder

30
Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...

Summary
This summary is machine-generated.

Adolescents' developing attitudes toward substances predict future substance use. Longitudinal changes in disposition, particularly the emergence of negative attitudes with age, significantly increase the risk for substance use onset.

Area of Science:

  • Developmental psychology
  • Adolescent substance use research
  • Behavioral science

Background:

  • Adolescence is a critical period for the development of attitudes and behaviors.
  • Understanding factors that predict substance use onset is crucial for prevention.

Purpose of the Study:

  • To propose and test a model where longitudinal changes in adolescents' dispositions influence age-related risk for substance use onset.
  • To identify dispositional variables and their developmental trajectories as predictors of substance use.

Main Methods:

  • Analysis of pooled data from 25 longitudinal studies.
  • Disposition calculated from eight variables including intentions, attitudes, beliefs, and lifestyle incongruence.
  • Substance use onset (alcohol, cigarettes, marijuana) analyzed based on prior dispositional status and recent changes.

Main Results:

  • Dispositional variables were highly correlated with measured attitudes and beliefs.
  • Adolescents showed a developmental shift from positive to negative dispositions with age.
  • Both dispositional status and recent dispositional changes strongly predicted substance use onset.

Conclusions:

  • Understanding disposition development is key for effective adolescent substance use interventions.
  • Focusing prevention programs on subordinate dispositional variables is recommended.
  • Multi-year and tailored interventions considering pre-intervention dispositions are advised.
