Summary
Violence victim rates declined for males, with fewer severe injuries like fractures. Less serious lesions became more common over the study period.
Area of Science:
- Forensic Medicine
- Public Health
- Trauma Research
Context:
- Analysis of 14,316 violence victims registered between 1991-2002.
- Data sourced from Odense University Hospital and the Institute of Forensic Medicine, University of Southern Denmark.
- Examines trends in violence-related injuries over an 11-year period.
Purpose:
- To investigate the incidence and nature of violence-related injuries in a defined population.
- To identify temporal trends in injury severity and mechanisms of harm.
- To assess changes in the proportion of less serious versus potentially severe lesions.
Summary:
- The incidence rate of violence was 9.9/1,000 for males and 3.4/1,000 for females.
- Male incidence rates decreased, while the proportion of less serious lesions increased.
- Proportions of severe injuries (fractures, deep wounds) and knife/firearm injuries remained stable.
Impact:
- Provides insights into evolving patterns of violence and injury.
- Informs public health strategies and resource allocation for violence prevention.
- Highlights a potential shift towards less severe, but possibly more frequent, violent encounters.

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...
01:28Conduct 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;...
01:30Oppositional Defiant Disorder
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.

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.
02:01Group Design
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between the two are due to...
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 recognition that people have...
