Summary
Unplanned drinking episodes are linked to negative outcomes. Measuring the number of unplanned drinks, not just if drinking was planned, better predicts risky alcohol consumption and consequences.
Area of Science:
- Psychology
- Addiction Research
- Behavioral Science
Background:
- Unplanned drinking episodes are associated with adverse outcomes, but research findings are mixed.
- Previous studies often used a dichotomous approach (planned vs. unplanned) to assess drinking.
- A continuous measure of unplanned drinks may offer a more accurate assessment of risk.
Purpose of the Study:
- To describe the occurrence of unplanned drinking episodes.
- To compare the predictive power of dichotomous versus continuous operationalizations of unplanned drinking on consequences.
Main Methods:
- 104 undergraduate students completed online surveys.
- Daily surveys over 14 days captured 325 drinking episodes.
- Assessed dichotomous (planned/unplanned) and continuous (drinks over intended limit) unplanned drinking.
Main Results:
- Most drinking episodes were planned but exceeded intended quantities.
- Only the continuous measure of unplanned drinking significantly predicted negative consequences.
- Continuous unplanned drinking (b = 0.25, IRR = 1.28) was a stronger predictor than dichotomous measures.
Conclusions:
- A nuanced, continuous operationalization of unplanned drinking is necessary for accurate risk assessment.
- Dichotomous measures may underestimate the risks associated with exceeding drinking intentions.
- Excessive unplanned alcohol consumption is a potential indicator of problematic drinking behaviors.

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...

01:08Timing and Consequences on Behavior
77
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant...

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...

One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

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,...

01:16Hypothesis Test for Test of Independence
3.5K
The test of independence is a chi-square-based test used to determine whether two variables or factors are independent or dependent. This hypothesis test is used to examine the independence of the variables. One can construct two qualitative survey questions or experiments based on the variables in a contingency table. The goal is to see if the two variables are unrelated (independent) or related (dependent). The null and alternative hypotheses for this test are:
H0: The two variables (factors)...
