Reliability and Validity01:29

Reliability and Validity

Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
Self-Report Tests of Personality01:22

Self-Report Tests of Personality

Self-report inventories are objective personality assessments that use multiple-choice items or numbered scales, typically ranging from 1 (strongly disagree) to 5 (strongly agree). They are often called Likert scales after Rensis Likert. These inventories are widely used due to their ease of administration and cost-effectiveness. One of the most prominent examples is the Minnesota Multiphasic Personality Inventory (MMPI), initially developed in the 1940s to assess abnormal personality traits.
Self-Presentation: Self-Monitoring and Self-Handicapping02:05

Self-Presentation: Self-Monitoring and Self-Handicapping

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 the way you...
Determination of Expected Frequency01:08

Determination of Expected Frequency

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...
Self-Evaluation: Self-Enhancement and Self-Verification03:00

Self-Evaluation: Self-Enhancement and Self-Verification

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...

Summary

A brief version of the Alcohol Expectancy Questionnaire-Adolescent (AEQ-A) was developed. This shortened scale effectively assesses adolescent alcohol expectancies and may aid brief interventions.

Area of Science:

  • Psychology
  • Addiction Research
  • Adolescent Health

Background:

  • Adolescent alcohol use is a significant public health concern.
  • Accurate assessment of alcohol expectancies is crucial for intervention.
  • Existing measures may be too lengthy for brief clinical settings.

Purpose of the Study:

  • To evaluate a brief, seven-item version of the Alcohol Expectancy Questionnaire-Adolescent (AEQ-AB).
  • To determine the psychometric properties of the AEQ-AB.
  • To assess its utility in brief adolescent alcohol assessments.

Main Methods:

  • The original AEQ-A was reduced to seven items.
  • Principal Components Analysis (PCA) was used for factor extraction.
  • Internal consistencies and correlations with criterion variables were examined.

Main Results:

  • Two factors emerged: General Positive Effects and Potential Negative Effects, explaining 46% of the variance.
  • The AEQ-AB demonstrated comparable internal consistencies to the original AEQ-A (0.50).
  • Scales significantly correlated with weekly alcohol consumption and heavy drinking frequency (p < 0.05).

Conclusions:

  • The AEQ-AB is a potentially useful tool for clinicians conducting brief assessments of adolescent alcohol expectancies.
  • This brief questionnaire may facilitate early intervention strategies.
  • Further cross-validation in diverse samples and settings is recommended.
