Surveys

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

CNS Depressants: Alcohol and Nicotine

182
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...

Mass Spectrometry: Alcohol Fragmentation

3.4K
Alcohols (R-OH) ionize to lose one non-bonded electron from the oxygen atom, forming molecular ions. Due to their tendency to fragment rapidly, the intensity of the molecular ion peak in the mass spectrum is weak or sometimes absent. The fragmentation patterns for alcohols occur in two ways, i.e. ⍺-cleavage and dehydration. During ⍺-cleavage, the bond at the ⍺-position adjacent to the hydroxyl group cleaves to give a resonance-stabilized cation and a radical. However,...

Summary
This summary is machine-generated.

Sexual alcohol expectancies influence how alcohol intoxication relates to condom use among men who have sex with men (MSM). Stronger expectancies amplify the inverted U-shape link between intoxication and condom-protected anal intercourse.

Area of Science:

  • Public Health
  • Behavioral Science
  • Addiction Research

Background:

  • Human immunodeficiency virus (HIV) transmission persists, particularly among men who have sex with men (MSM) in the U.S.
  • Alcohol consumption is linked to risky sexual behaviors, with alcohol expectancies potentially mediating this relationship.

Purpose of the Study:

  • To investigate the moderating role of sexual alcohol expectancies (SAEs) on the relationship between daily alcohol intoxication and sexual behavior in moderate- to heavy-drinking MSM.

Main Methods:

  • Secondary analysis of 248 moderate- to heavy-drinking MSM.
  • Ecological momentary assessment (EMA) over two 23-day periods.
  • Assessed daily alcohol intoxication, sexual behavior, and SAEs using validated questionnaires and daily assessments.

Main Results:

  • SAEs moderated a curvilinear association between alcohol intoxication and condom-protected anal intercourse.
  • This moderation resulted in a more pronounced inverted U-shape relationship between intoxication and condom use among individuals with strong SAEs.
  • No significant moderation effect was observed for condomless anal intercourse (CAI).

Conclusions:

  • Sexual alcohol expectancies appear to influence the association between alcohol intoxication and sexual behavior in MSM.
  • SAEs do not appear to moderate the relationship between alcohol intoxication and condomless anal intercourse.
