Summary
A new screening tool accurately identifies very low food security (VLFS) risk, a critical health-related social need. This validated screen helps connect vulnerable populations with essential nutrition services.
Area of Science:
- Public Health
- Health Services Research
- Nutrition Science
Background:
- Mandatory screening for health-related social needs (HRSNs) by CMS since 2024.
- Supplemental Nutrition Services are provided to patients with food insecurity (FI) via 1115 Demonstration waivers.
- Massachusetts implemented a stricter screening protocol for very low food security (VLFS).
Purpose of the Study:
- To develop a sensitive, specific, and valid screening tool to identify risk for very low food security (VLFS).
- To address the lack of a dedicated screening tool for VLFS.
Main Methods:
- Compared combinations of questions against the USDA Household Food Security Survey Module.
- Utilized 2022 Current Population Survey data.
- Evaluated sensitivity, specificity, and predictive values.
Main Results:
- A single yes/no question identified VLFS risk with high sensitivity (92.2%–97.2%) and specificity (96.2%–97.4%).
- The screen demonstrated validity across diverse US households, with and without children.
- The developed screen is effective for identifying individuals at risk of very low food security.
Conclusions:
- The developed VLFS screen is recommended for states implementing stringent FI screening protocols.
- This tool can improve the identification and support for individuals experiencing severe food insecurity.

1.7K
The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

01:29Reliability and Validity
13.9K
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.

In vitro dissolution and drug release tests assess how quickly and how much of a drug is released from its dosage form into an aqueous medium under standardized laboratory conditions. These tests are essential tools in pharmaceutical development and quality assurance, offering insight into the drug's performance before clinical use.During formulation development, dissolution testing identifies incomplete or inconsistent drug release issues. It also supports decisions on selecting the optimal...

Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.

Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.

01:30Regulation of Food Intake
2.9K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
