Summary
College students anticipate increased alcohol demand but don't change their drinking. Projected future alcohol demand shows potential for predicting future use, though not uniquely when baseline factors are considered.
Area of Science:
- Psychology
- Addiction Science
- Public Health
Background:
- Alcohol demand, reflecting its reinforcing value, correlates with alcohol consumption.
- College students may underestimate future substance use escalation.
- Projected future alcohol demand is a novel construct to explore in this population.
Purpose of the Study:
- To investigate projected future alcohol demand in heavy-drinking college students.
- To determine if projected future demand predicts subsequent alcohol use.
- To compare projected demand with current demand in predictive utility.
Main Methods:
- Participants completed standard and projected alcohol purchase tasks at baseline.
- Baseline measures included past-month alcohol consumption and risk.
- Follow-up assessments occurred 3 months later, including repeat alcohol demand and consumption measures.
Main Results:
- College students projected increased alcohol demand over 3 months but did not change actual demand.
- Projected future demand measures were associated with subsequent alcohol use.
- Projected demand was not a unique predictor of future alcohol use when baseline use and risk were controlled.
Conclusions:
- Projected alcohol demand is a novel measure with potential predictive value for future alcohol use trajectories.
- Contrasting projected with current demand may enhance prediction.
- Further research is needed to refine the utility of projected demand measures.

Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

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...

Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

Stress often leads to unhealthy habits like smoking, excessive drinking, and overeating, which offer short-term relief but ultimately increase long-term health risks. These behaviors create a cycle that temporarily lowers stress levels but can result in severe long-term health consequences. Breaking these habits is essential to reduce the risk of chronic diseases and improve overall well-being. Three primary changes that support better health include quitting smoking, reducing alcohol intake,...

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...

Inhibitors are molecules that reduce enzyme activity by binding to the enzyme. In a normally functioning cell, enzymes are regulated by a variety of inhibitors. Drugs and other toxins can also inhibit enzymes. Some inhibitors bind to the enzyme’s active site, while others inhibit enzymatic activity by binding to other sites on the protein structure.
