Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

34
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Self-Discrepancy Theory02:45

Self-Discrepancy Theory

18.3K
One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

22
A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Longitudinal Research

11.8K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Modeling in Therapy01:26

Modeling in Therapy

38
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...

Conduct Disorder01:28

Conduct Disorder

23
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

Excessive smartphone use in children can lead to more externalizing behavior problems over time. Early interventions promoting healthy digital habits are crucial for addressing these behavioral challenges.

Area of Science:

  • Child Psychology
  • Behavioral Science
  • Digital Media Studies

Background:

  • Childhood externalizing behaviors are a significant concern for parents and educators.
  • The increasing prevalence of smartphone use among children raises questions about its impact on behavior.
  • Understanding the interplay between digital habits and behavioral development is critical.

Purpose of the Study:

  • To investigate the longitudinal, reciprocal relationship between smartphone dependence and externalizing behavior problems in school-aged children.
  • To determine if smartphone dependence predicts future externalizing behaviors or vice versa.
  • To examine the temporal stability of these two constructs over a one-year period.

Main Methods:

  • Longitudinal study with 379 school-aged children (7-12 years) assessed over four six-month intervals.
  • Utilized the Smartphone Overdependency Observer Scale and the Korean Version of the Child Behavior Checklist.
  • Employed an autoregressive cross-lagged model to analyze bidirectional relationships, controlling for covariates.

Main Results:

  • Both smartphone dependence and externalizing behavior problems showed significant stability over time.
  • Increased smartphone dependence at one time point predicted higher levels of externalizing behavior problems in subsequent periods.
  • Externalizing behavior problems did not predict future smartphone dependence, suggesting a unidirectional influence.

Conclusions:

  • Smartphone dependence is a significant predictor of escalating externalizing behavior problems in children.
  • Early intervention strategies focusing on establishing healthy digital habits are essential.
  • Findings underscore the need for proactive measures to mitigate behavioral issues linked to excessive screen time.
