Summary
This school-based program improved peer relationships for Japanese junior high students. However, aggressive behavior reduction requires further program modifications.
Area of Science:
- Psychology
- Education
- Sociology
Background:
- Aggressive behavior is a significant concern in junior high school students.
- School-based interventions are a potential strategy to address behavioral issues.
- Understanding the impact of targeted programs on social interactions and aggression is crucial.
Purpose of the Study:
- To evaluate the effectiveness of a school-based intervention program on aggressive behavior in Japanese junior high school students.
- To assess changes in students' relationships with classmates following the intervention.
- To determine if the timing of program implementation influences its impact on behavior.
Main Methods:
- A quasi-experimental design was used with 104 seventh-graders in Japan.
- Two groups received the intervention: an initial treatment group and a delayed treatment group.
- Surveys were administered at three time points (Time 1, Time 2, Time 3) to measure aggressive behavior and social relationships.
Main Results:
- The initial intervention group showed a significant increase in appropriate relationships with classmates.
- Aggressive behavior significantly decreased from Time 1 to Time 3 in both groups.
- A significant decrease in aggressive behavior was also observed from Time 2 to Time 3 in the delayed treatment group, but no direct treatment group effect was found.
Conclusions:
- The school-based intervention positively impacted peer relationships among students.
- While overall aggressive behavior decreased, the program as implemented did not demonstrate a significant treatment group effect.
- Further modifications to the intervention may be necessary to more effectively reduce aggressive behavior in this population.

01:47Aggression
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for hire...
01:24Treatment Strategies for Psychological Disorders
Treatment approaches for psychological disorders fall into three main categories: psychological, biological, and sociocultural. Each approach targets different aspects of mental health, requiring varying levels of education and training.
Psychological therapies focus on modifying emotions, thoughts, and behaviors through talking, interpreting, listening, rewarding, challenging, and modeling. Clinical psychologists, counselors, and social workers commonly practice psychotherapy. Clinical...

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;...
01:30Community Based Intervention
Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.

02:04Bullying
A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is bullying.
01:22Behavior Therapy
Behavior therapy incorporates diverse techniques rooted in classical conditioning principles to address maladaptive behaviors and anxiety disorders. These methods aim to reduce avoidance behaviors, foster adaptive coping mechanisms, and alter associations between stimuli and responses, making them effective in a wide range of therapeutic contexts.
