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...

Feedback Inhibition

Feedback Inhibition

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Self-Regulation

Self-Regulation

Self-regulation, also known as self-control, encompasses a range of cognitive and behavioral processes that allow individuals to adjust their internal states and outward actions to align with socially acceptable norms and long-term goals. It plays a fundamental role in adaptive functioning, from resisting impulsive behaviors to persisting through challenging tasks. While its benefits are widely recognized, self-regulation is not limitless. Muraven and Baumeister's theory posits that...

Regression Toward the Mean

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...

Introspection

Introspection

Introspection, long upheld as a reliable route to self-knowledge, involves examining one's thoughts, emotions, and mental processes. It underpins many psychological practices, from mindfulness meditation to psychotherapy and self-help strategies. However, empirical evidence challenges the accuracy of introspection as a means of understanding oneself.Limitations of Introspective InsightSeminal work by Nisbett and Wilson demonstrated that individuals are frequently unaware of the true causes...

Area of Science:

Public Health
Psychology
Behavioral Science

Background:

Personalized-feedback interventions (PFIs) are increasingly evaluated for reducing problem drinking.
Previous research includes randomized controlled trials (RCTs) and systematic reviews.
A meta-analysis specifically examined brief, single-session PFIs without therapeutic guidance.

Purpose of the Study:

To meta-analyze the effectiveness of single-session, personalized-feedback interventions for reducing problem drinking.
To evaluate the combined effect size of these interventions across multiple studies.

Main Methods:

A meta-analysis was conducted in 2008.
Fourteen RCTs of single-session PFIs without therapeutic guidance were identified and analyzed.
Alcohol consumption reduction was the primary outcome measure.

Main Results:

The pooled standardized effect size for reduced alcohol consumption was d=0.22 (95% CI=0.16, 0.29).
The number needed to treat was 8.06, indicating moderate effectiveness.
No significant heterogeneity was found among the included studies (p=0.69).

Conclusions:

Single-session PFIs without therapeutic guidance are a viable and potentially cost-effective method for reducing problem drinking.
The internet provides a scalable platform for delivering these interventions.
Further research is needed on long-term effectiveness, use in stepped-care models, and application to diverse populations and settings.
