Summary
Early conduct problems (CPs) are linked to significant alcohol issues in young adults, especially by age 18. These associations diminish over time, with pathways involving adolescent alcohol use and crime being key for persistent CPs.
Area of Science:
- Developmental Psychology
- Addiction Research
- Criminology
Background:
- Conduct problems (CPs) in childhood and adolescence are linked to later alcohol-related issues.
- Understanding developmental trajectories of CPs is crucial for predicting adult outcomes.
- Escalation of early CPs into criminal behavior and heavy alcohol use are potential pathways.
Purpose of the Study:
- To investigate the association between developmental trajectories of conduct problems (CPs) and alcohol-related problems in emerging adulthood.
- To examine the mediating roles of adolescent alcohol consumption and criminal behavior in this association.
- To analyze the long-term impact of different CPs onset types on alcohol-related problems.
Main Methods:
- Analysis of data from 3,038 participants in the Avon Longitudinal Study of Parents and Children (UK birth cohort).
- Categorization of participants based on conduct problem trajectories ('low', 'childhood-limited', 'adolescent-onset', 'early-onset persistent') from ages 4 to 13.
- Latent growth curve modeling to assess nonlinear changes in alcohol-related problems (ages 18-23) and mediation analysis for adolescent alcohol/criminal behavior (age 15).
Main Results:
- Both 'early-onset persistent' and 'adolescent-onset' CPs were associated with higher alcohol-related problems at age 18, but this association decreased after age 19.
- 'Early-onset persistent' CPs showed an indirect effect on 18-year-old alcohol problems via adolescent alcohol and criminal behavior.
- No significant indirect effect was found for 'adolescent-onset' CPs through these mediators.
Conclusions:
- Strong links exist between early CPs, adolescent substance use, criminal behavior, and alcohol problems at age 18.
- The association between early CPs and alcohol-related problems significantly weakens throughout emerging adulthood.
- 'Early-onset persistent' conduct problems represent a critical pathway to adolescent risk behaviors and subsequent alcohol problems.

01:27Emerging Adulthood
539
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...

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

01:17Erikson's Theory on Socioemotional Development during Adolescence
963
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...

01:18Cognitive 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...

According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is...

Adolescence is a pivotal period of identity formation, during which individuals begin to answer questions central to their sense of self, such as "Who am I?" and "Who do I hope to become?" Both parents and peers play critical roles in guiding adolescents through this complex developmental phase.
