The Inability of Self-affirmations to Decrease Defensive Bias Toward an Alcohol-Related Risk Message Among High-Risk
Journal of American College Health : J of ACH
|January 13, 2015
Summary
A self-affirmation task did not reduce college alcohol misuse. Preexisting beliefs also did not predict behavior change, suggesting other strategies are needed for college alcohol misuse prevention.
Area of Science:
- Psychology
- Public Health
- Behavioral Science
Background:
- College alcohol misuse remains a significant public health concern.
- Understanding factors that influence behavior change is crucial for effective prevention strategies.
Purpose of the Study:
- To evaluate the effectiveness of a self-affirmation task in reducing college alcohol misuse.
- To determine the role of preexisting beliefs in predicting changes in alcohol-related behaviors.
Main Methods:
- 110 heavy-drinking undergraduates were randomized to complete either a self-affirmation or a control task.
- Participants received an alcohol risk message, and their beliefs and behaviors were assessed.
- A 2-week online follow-up monitored alcohol-related behaviors.
Main Results:
- Both groups showed increased perceived problem importance, but personal risk perception did not change.
- Significant declines in peak alcohol consumption were observed in both groups, with no between-group differences.
- Preexisting beliefs explained 5% to 10% of the variance in drinking outcomes.
Conclusions:
- Self-affirmation tasks do not appear to reduce defensive processing or alter high-risk drinking behaviors in college students.
- These findings suggest that self-affirmation should not replace more effective college alcohol misuse prevention strategies.

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...

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...

Self-verification is a fundamental psychological drive wherein individuals seek affirmation of their self-concept from others, striving for consistency between their internal self-view and external perceptions. This drive operates even when the self-concept is negative, influencing interpersonal behavior and feedback preferences in complex and often counterintuitive ways. Unlike the self-enhancement motive, which seeks positive evaluations, self-verification prioritizes coherence and...

Self-serving bias is a cognitive phenomenon in which individuals attribute positive outcomes to internal factors such as their abilities, intelligence, or effort while attributing negative outcomes to external circumstances. This cognitive distortion helps maintain self-esteem but can also impede objective self-assessment.Theoretical Explanations of Self-Serving BiasTwo primary theories explain the self-serving bias: the cognitive explanation and the motivational explanation.The cognitive...

Self-esteem, a central component of psychological well-being, is actively maintained through various cognitive and behavioral strategies. Individuals employ specific mechanisms to preserve a positive self-concept and mitigate threats to their self-worth, particularly in contexts involving social evaluation or personal feedback. Four primary techniques are commonly used to sustain self-esteem.Manipulating AppraisalsOne prominent strategy involves manipulating appraisals from others. Individuals...
