Reliability and Validity

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.

Leaky Scanning

Leaky Scanning

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Distribution Reliability and Automation

Distribution Reliability and Automation

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

Scanning Electron Microscopy

Scanning Electron Microscopy

A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.

Naturalistic Observations

Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

Voltammetric Techniques: Linear-Scan (E vs Time)

Voltammetric Techniques: Linear-Scan (E vs Time)

Polarography is a classical voltammetric technique used to analyze electrochemical reactions. This method applies a linear potential sweep to a dropping mercury electrode (DME), and the resulting current is measured. A dropping mercury electrode is commonly used as the working electrode in polarography. It consists of a capillary tube filled with mercury, where the tiny droplet forms at the tip. This droplet continuously drops from the capillary, creating a new electrode surface for each...

Background:

The Mealtime Scan (MTS) is a tool for assessing dining environments in Long Term Care (LTC).
MTS has been updated to MTS+ to ensure standardization and responsiveness to changes.
This study focuses on the changes in MTS+ and its inter-rater reliability.

Purpose of the Study:

To provide an overview of the modifications in the new MTS+ tool.
To describe the inter-rater reliability of the MTS+ tool.
To evaluate the reliability of assessing physical, social, and relational dining environments.

Main Methods:

The observational and scoring methods for dining environments were updated into MTS+.
Two trained assessors evaluated inter-rater reliability through 45 observations across nine dining rooms in three LTC homes.
Interclass Correlation Coefficient (ICC) was used to assess reliability.

Main Results:

MTS+ demonstrated good reliability for orientation cues (ICC: 0.75), social environment (ICC: 0.78), and relational activities (ICC: 0.78).
Reliability was poor for the physical environment (ICC: 0.48) and moderate for the overall dining quality rating (ICC: 0.67).

Conclusions:

MTS+ is effective and practical for intervention studies, particularly when one assessor conducts repeat observations.
Limitations exist in MTS+ reliability, especially for the physical environment assessment.
Further assessor training may enhance the reliability of MTS+.
