Cross-Sectional Research

12.9K
In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Emerging Adulthood01:27

Emerging Adulthood

971
Jeffrey Arnett's concept of emerging adulthood offers a framework to understand the unique developmental stage between adolescence and full-fledged adulthood, generally from ages 18 to 25. This period is marked by extensive exploration and shifts in identity, relationships, and career choices, a process known in psychology as role experimentation. Emerging adulthood reflects the evolving cultural expectations surrounding adulthood and the dynamic process of personal transformation during...

Substance Use Disorders Affecting Sleep

529
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.
Understanding the concepts of physical dependence,...

Cognitive Dissonance

37.9K
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...

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.

Revisionist Views of Adolescent and Adult Cognition

380
A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...

Summary

Heavy drinking nonstudents consume more alcohol on weekends than weekdays. Social expectancies drive weekend drinking, while tension-reduction and social expectancies influence weekday drinking patterns in emerging adults.

Area of Science:

  • Psychology
  • Public Health
  • Sociology

Background:

  • Emerging adults who do not attend college represent an at-risk population for heavy alcohol consumption.
  • Understanding differential drinking patterns based on the day of the week is crucial for targeted interventions.
  • Alcohol expectancies and demographic factors may play a significant role in shaping these drinking behaviors.

Purpose of the Study:

  • To investigate weekday versus weekend drinking patterns in nonstudent emerging adults.
  • To examine the association of specific alcohol expectancies (sociability, tension reduction) and demographic factors (age, sex) with differential drinking.
  • To control for harmful drinking and holiday drinking when analyzing these associations.

Main Methods:

  • A sample of 238 heavy-drinking, nonstudent emerging adults (63.4% male, mean age 21.92) reported daily drinking over 30 days.
  • Participants completed validated measures of harmful drinking, alcohol expectancies, and demographic information.
  • Multilevel modeling was used to analyze the associations between expectancies, demographics, and drinking patterns, controlling for covariates.

Main Results:

  • Weekend drinking (Thursday-Saturday) accounted for 63% of total drinks consumed.
  • Weekday drinking was associated with tension-reduction expectancies, social expectancies, sex, and age.
  • Weekend drinking increases were linked to social expectancies, but not tension-reduction expectancies, after controlling for covariates.

Conclusions:

  • Alcohol expectancies and drinking contexts are vital for understanding nonstudent emerging adult drinking behaviors.
  • The distinct roles of tension-reduction and social expectancies suggest different cognitive pathways for weekday versus weekend drinking.
  • Both tension-reduction and social-facilitation expectancies should be targeted in risk-reduction efforts for this population.
