Aggression

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...

Group Design

Group 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...

Bullying

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.

Self-Presentation: Self-Monitoring and Self-Handicapping

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about the way you...

Secondary Motives: Affiliation Motivation and Aggression Motivation

Secondary Motives: Affiliation Motivation and Aggression Motivation

Affiliation motivation is the intrinsic desire to connect with others and belong to a social group, which plays a crucial role in forming and maintaining personal relationships. This type of motivation is essential for psychological well-being, as it provides individuals with a sense of community and support. An example of this is a student who joins a study group in order to feel a sense of connection. People with high affiliation motivation actively seek social approval, take satisfaction in...

Deindividuation

Deindividuation

Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Summary

Violence involvement, including fighting and weapon carrying, significantly distinguishes youth suicide attempts from ideation. These factors, along with psychiatric conditions and demographics, are key predictors of suicide attempts versus ideation.

Area of Science:

Psychology
Public Health
Criminology

Background:

Distinguishing between suicide ideation and attempts is crucial for targeted prevention.
Violence involvement is a understudied factor in differentiating suicide behaviors.

Purpose of the Study:

To identify factors differentiating youth suicide attempters from ideators.
To examine the role of violence involvement in suicidality.

Main Methods:

Analysis of the 2001 Youth Risk Behavior Survey data (1,439 ideators, 1,097 attempters).
Inclusion of violence measures (fights, dating violence, weapon carrying) and controls for psychiatric disorders, risky behaviors, school integration, and demographics.
Supplementary analysis on a larger dataset (N=11,546) to compare ideators with non-suicidal youth.

Main Results:

Violence involvement (fighting OR=2.18, weapon carrying OR=1.13) significantly differentiated attempts from ideation, controlling for other factors.
Psychiatric factors (major depression, cocaine use, suicide plan) and demographic factors (gender, age, ethnicity, region) also predicted attempts over ideation.
Violence involvement also differentiated suicide ideators from non-suicidal youth.

Conclusions:

Violence involvement is a significant factor in distinguishing suicide attempts from ideation and ideation from non-suicidal states.
A combination of violence, psychiatric, and demographic factors predict varying levels of suicidality.
The findings support the interpersonal theory of suicide, highlighting the capability for suicide through violence involvement.
