Summary
Alcohol expectancies influence the link between problematic drinking and suicidal thoughts. Specific expectancies, like mood alteration, may increase or decrease this association, highlighting a need for further research.
Area of Science:
- Psychology
- Addiction Research
- Mental Health
Background:
- Alcohol expectancies are theorized to mediate the relationship between problematic drinking and suicidal ideation.
- Understanding this link is crucial for developing targeted interventions.
Purpose of the Study:
- To investigate whether alcohol expectancies moderate the association between problematic drinking and suicidal ideation.
- To examine the specific roles of different types of alcohol expectancies.
Main Methods:
- Secondary analysis of cross-sectional survey data from 444 individuals in domestic violence intervention programs.
- Utilized parallel and exploratory factor analyses to identify alcohol expectancy factors.
- Employed multiple linear regression with bootstrapping to test moderation effects, controlling for gender and depressive symptoms.
Main Results:
- A three-factor structure of alcohol expectancies was identified: disinhibition/negative mood, positive mood, and physical/cognitive effects.
- Problematic drinking was negatively associated with suicidal ideation at low levels of disinhibition/negative mood expectancies, becoming more positive as expectancies increased.
- The association between problematic drinking and suicidal ideation shifted based on positive mood expectancies.
Conclusions:
- Preliminary findings suggest mood-altering and disinhibiting alcohol expectancies may influence the link between problematic drinking and suicidal thinking.
- Further longitudinal research is needed to confirm these moderation effects during acute intoxication and control for psychiatric symptoms.

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...

01:16Hypothesis Test for Test of Independence
6.9K
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)...

182
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,...

01:08Determination of Expected Frequency
2.5K
Suppose one wants to test independence between the two variables of a contingency table. The values in the table constitute the observed frequencies of the dataset. But how does one determine the expected frequency of the dataset? One of the important assumptions is that the two variables are independent, which means the variables do not influence each other. For independent variables, the statistical probability of any event involving both variables is calculated by multiplying the individual...

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...

894
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...
