Cognitive Dissonance

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

The Stanford Prison Experiment

The Stanford Prison Experiment

The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.

Self-Evaluation Maintenance Model

Self-Evaluation Maintenance Model

The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

Trait and State Self-Esteem

Trait and State Self-Esteem

The term self-esteem is often used generically, to refer to how people feel about themselves. However, according to research, there are three distinct constructs that should not be used interchangeably (Brown & Marshall, 2006).

Sources of Self-Esteem II: Performance Feedback

Sources of Self-Esteem II: Performance Feedback

Self-esteem is intricately tied to our perception of competence and our ability to exert control over our lives. One of the primary sources of this perception is performance feedback — the ongoing evaluation of our actions in terms of success and failure. According to Franks and Marolla (1976), people derive self-worth from experiencing themselves as causal agents, capable of achieving goals and overcoming obstacles. This process nurtures a critical component of self-esteem: self-efficacy,...

Milgram's Obedience to Authority

Milgram's Obedience to Authority

Obedience to authority is classically demonstrated in a more famous series of social psychology experiments performed by Stanley Milgram. He was a social psychology professor at Yale who was influenced by the trial of Adolf Eichmann, a Nazi war criminal. Eichmann’s defense for the atrocities he committed was that he was “just following orders.”

This summary is machine-generated.

Military combat exposure may increase suicide risk by building a capability for self-harm. This study found combat experiences predicted acquired capability, a key suicide factor, in service members.

Area of Science:

Psychology
Military Medicine
Suicidology

Background:

Rising suicide rates in military personnel are a significant public health concern.
The interpersonal-psychological theory of suicide identifies belongingness, burdensomeness, and acquired capability as key factors.
Military experience, particularly combat exposure, may influence the acquired capability for suicide.

Purpose of the Study:

To investigate the relationship between combat experiences and the acquired capability for suicide in military personnel.
To test if combat exposure influences acquired capability independently of other suicide risk factors.
To examine whether combat experiences predict perceived burdensomeness or thwarted belongingness.

Main Methods:

Utilized clinical and nonclinical samples of military personnel deployed to Iraq.
Assessed combat experiences, depression, post-traumatic stress disorder (PTSD) symptoms, previous suicidality, and suicide risk factors.
Employed statistical analyses to determine predictors of acquired capability, burdensomeness, and thwarted belongingness.

Main Results:

Greater combat experience significantly predicted acquired capability for suicide.
Combat experiences were a predictor of acquired capability beyond depression, PTSD, and other common risk factors.
Combat experiences did not predict perceived burdensomeness or thwarted belongingness.

Conclusions:

Combat exposure may enhance the acquired capability to overcome the fear and pain associated with suicide in military personnel.
Combat experiences may represent a specific mechanism contributing to elevated suicide risk in this population.
Findings have implications for targeted clinical interventions and suicide prevention strategies within the military.
