Summary
Trauma recidivism varies by injury type. Repeated gunshot wounds lead to more severe injuries and higher mortality, unlike blunt assaults or stabbings. Early rehabilitation is crucial for high-risk patients.
Area of Science:
- Trauma Surgery
- Public Health
- Injury Prevention
Background:
- Interpersonal violence results in significant trauma admissions.
- Outcomes for trauma recidivists, especially from intentional trauma, are not well-defined.
- Prior trauma history affects 25-44% of trauma patients.
Purpose of the Study:
- To investigate if violence escalates with successive trauma incidence.
- To determine if injury severity increases with repeated trauma admissions.
- To analyze outcomes for trauma recidivists based on injury mechanism.
Main Methods:
- Data from an urban level I trauma center registry were analyzed.
- Included patients with injuries from blunt assault, stabbing, and firearm incidents.
- Primary outcomes: mortality, injury mechanism, and severity for successive admissions.
Main Results:
- Blunt assault and stabbing victims were more likely to be recidivists than firearm victims.
- Violent re-injury severity increased only for repeated gun violence victims.
- Gunshot wounds at every admission correlated with the highest mortality risk.
Conclusions:
- Recidivism for interpersonal violence significantly impacts trauma center admissions.
- Successive blunt assaults did not lead to worsening injuries.
- Repeated gunshot wounds result in more severe injuries and worse prognosis than repeated stabbings.

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...
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.
01:20Traumatic Memory
Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual remembers mundane...
01:17Bonanno's Theory of Grieving
Grieving is a complex psychological and emotional process that varies significantly among individuals. George Bonanno's research on bereavement identified four distinct patterns of grieving, offering a nuanced understanding of how people cope with significant loss, such as the death of a spouse, over extended periods. These patterns — resilience, recovery, chronic dysfunction, and delayed grief — highlight the diversity in emotional responses and adaptive mechanisms.

01:27Post-traumatic Stress Disorder
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.

01:29Psychological and Sociocultural Causes of Schizophrenia
Schizophrenia, a complex psychiatric disorder, has been historically misunderstood. Early psychological theories attributed its origins to childhood trauma and unresponsive parenting. However, contemporary research largely rejects these notions, favoring the vulnerability-stress hypothesis. This model proposes that individuals with a genetic predisposition to schizophrenia may develop the disorder following exposure to significant environmental stressors. Notably, studies on high-risk...
