Insights

A new scale, the Children's Scale of Hostility and Aggression: Reactive/Proactive (C-SHARP), effectively measures aggression and hostility in children with developmental disabilities (DD). This tool provides a detailed analysis previously unavailable for this population.

Area of Science:

  • Child Psychology
  • Developmental Disabilities Research
  • Behavioral Assessment

Background:

  • Existing aggression scales lack detailed analysis for children.
  • No validated scales are available for children with developmental disabilities (DD).

Purpose of the Study:

  • To introduce and validate the Children's Scale of Hostility and Aggression: Reactive/Proactive (C-SHARP).
  • To assess aggression and hostility in children with DD.

Main Methods:

  • Parents of 365 children with DD completed the C-SHARP.
  • Factor analysis identified five factors: Verbal Aggression, Bullying, Covert Aggression, Hostility, and Physical Aggression.
  • Reliability (coefficient alpha) and validity (age/gender differences) were examined.

Main Results:

  • The C-SHARP demonstrated good internal consistency, with alpha ranging from 0.74 to 0.92.
  • Factor analysis confirmed a robust 5-factor structure.
  • Preliminary normative data were established, and validity was supported by expected group differences.

Conclusions:

  • The C-SHARP is a promising and reliable tool for assessing aggression and hostility in children with DD.
  • This scale fills a critical gap in the assessment of behavioral challenges in this population.

Conduct Disorder01:28

Conduct Disorder

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;...
Aggression01:47

Aggression

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...

Social Foundations of Self II: The Generalized Other

According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group effort.
Bullying02:04

Bullying

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.
Adler's Individual Psychology01:28

Adler's Individual Psychology

Alfred Adler, a prominent figure in psychology, founded the school of individual psychology. In contrast to Freud's emphasis on sexual or aggressive motives, Adler suggested that individuals are primarily motivated by their purposes and goals. He believed that people strive for perfection rather than pleasure. Adler argued that individuals could creatively act upon their genetic inheritance and environmental experiences to shape their own lives, emphasizing conscious motivation over unconscious...
Socioemotional Development during Infancy01:30

Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.
