Summary
A new tool, the Nutrition Environment Measures Survey-Vending (NEMS-V), was developed to assess vending machine nutrition environments. This reliable and valid instrument supports public health initiatives for healthier food options in businesses, schools, and communities.
Area of Science:
- Public Health Nutrition
- Health Policy
- Environmental Health
Background:
- Vending machines are prevalent in public spaces, influencing dietary choices.
- Existing tools lacked comprehensive assessment of the vending machine nutrition environment.
- A need existed for a reliable and valid instrument to evaluate vending machine offerings.
Purpose of the Study:
- To develop and validate the Nutrition Environment Measures Survey-Vending (NEMS-V) instrument.
- To ensure NEMS-V provides reliable and comparable data across diverse settings.
- To support public health initiatives aimed at improving vending machine nutrition.
Main Methods:
- Instrument development through collaboration of students, professionals, and community leaders.
- Rigorous interrater reliability testing among trained evaluators.
- Validation against established nutrition assessment criteria.
Main Results:
- High interrater reliability was achieved in evaluating vending machine products.
- The NEMS-V instrument demonstrated consistency and comparability.
- Successful dissemination to public health partners.
Conclusions:
- NEMS-V is a reliable and valid tool for assessing vending machine nutrition environments.
- The instrument can guide policy and environmental changes for healthier options.
- NEMS-V serves as a model for promoting healthier vending practices in various settings.

01:29Measures of Intelligence
Psychologists measure intelligence by using standardized tests that produce a score known as the intelligence quotient or IQ. To understand IQ tests, it's important to recognize the key principles behind their construction: validity, reliability, and standardization.
Validity refers to how well a test measures what it claims to measure. An intelligence test should accurately assess intelligence rather than another characteristic, like anxiety. Criterion validity is one way to evaluate this; it...

02:16Surveys
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.
