Summary
The Characteristics of Responsible Drinking Survey (CHORDS) is a new, reliable tool for assessing college students' responsible drinking beliefs and behaviors. It demonstrates validity and offers promise for future research and practice in this area.
Area of Science:
- Psychology
- Public Health
- Survey Methodology
Background:
- College student drinking behaviors present significant public health concerns.
- Existing instruments may not adequately capture the multifaceted nature of responsible drinking.
- A need exists for a psychometrically sound measure of responsible drinking constructs.
Purpose of the Study:
- To report the development and psychometric evaluation of the Characteristics of Responsible Drinking Survey (CHORDS).
- To establish the reliability and validity of the CHORDS for assessing responsible drinking.
- To provide a novel instrument for empirical investigation of responsible drinking dimensions.
Main Methods:
- The CHORDS underwent rigorous development, including four pretesting phases and a final posttest.
- A randomly selected convenience sample of 729 college students participated.
- Psychometric properties were assessed using Cronbach's alpha, split-half reliability, principal components analysis, and Spearman rho.
Main Results:
- The CHORDS demonstrated high internal consistency and split-half reliability.
- Factor analysis supported the proposed five-scale structure of the instrument.
- Subscale scores correlated with alcohol consumption behaviors, indicating concurrent validity.
Conclusions:
- The CHORDS is the first instrument developed to specifically measure responsible drinking beliefs and behaviors.
- The survey yielded valid and reliable data in a college student population.
- The CHORDS is a promising tool for practitioners and researchers studying responsible alcohol consumption.

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

01:21Introduction to Test of Independence
In statistics, the term independence means that one can directly obtain the probability of any event involving both variables by multiplying their individual probabilities. Tests of independence are chi-square tests involving the use of a contingency table of observed (data) values.
The test statistic for a test of independence is similar to that of a goodness-of-fit test:

01:24Substance Use Disorders Affecting Sleep
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.

01:27Production of Alcohol
Continuous fermentation is a key strategy in industrial ethanol production, particularly when efficiency, scalability, and high yields are essential. This approach allows for uninterrupted operation and optimized resource utilization. The primary feedstock, corn starch, undergoes enzymatic hydrolysis facilitated by α-amylase and glucoamylase. These enzymes break down the starch into fermentable sugars such as glucose, which are readily assimilated by fermentative microorganisms.Fermentation...
01:22Self-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.
01:28Survey Safety
Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...
