This study aimed to develop a valid and reliable scale for determining teachers' needs to increase their efficiency in professional practice. The stages of creating an item pool, consulting expert opinions, pilot testing, and conducting validity and reliability analyses were followed. Initially, a 46-item pool was created based on a literature…

Background: Understanding current practice is crucial for implementing Health Promoting Schools (HPS) and Whole School Approaches to Physical Activity (WSA-PA). This study validated two survey tools to assess HPS and WSA-PA implementation, respectively. Methods: Content validity was established via literature review and expert and target group…

The purpose of this study is twofold: (1) to develop and validate a five-tier diagnostic instrument for respiration and photosynthesis; (2) to uncover senior high school students' genuine misconceptions in Mainland China and explore the characteristics of their sources and formation mechanisms. To achieve these aims, a five-tier diagnostic…

In this digital ITEMS module, Dr. Jacqueline Leighton and Dr. Blair Lehman review differences between think-aloud interviews to measure problem-solving processes and cognitive labs to measure comprehension processes. Learners are introduced to historical, theoretical, and procedural differences between these methods and how to use and analyze…

As an alternative to Cronbach's [alpha] for estimating scale reliability, McDonald's [omega] has attracted increased attention within the methodological community for its less stringent measurement assumptions. Notwithstanding, [omega] is still seldom used by practitioners, likely due to its unavailability in popular software packages (e.g., SPSS)…

Purpose: The purpose of this study was to extend the assessment of the psychometric properties of the Modified Barium Swallow Impairment Profile (MBSImP). Here, we re-examined structural validity and internal consistency using a large clinical-registry data set and formally examined rater reliability in a smaller data set. Method: This study…

Questionnaire scales that are mixed-worded, i.e. include both positively and negatively worded items, often suffer from issues like low reliability and more complex latent structures than intended. Part of the problem might be that some responders fail to respond consistently to the mixed-worded items. We investigated the prevalence and impact of…

The purpose of our study was to assess the test-retest reliability and concurrent validity of the 30 sec Sit to Stand test in a sample of adolescents. We recruited 30 male (58%) and 22 female (42%) participants (mean age = 15.77 years ± 0.46). Participants completed the 30-sec Sit to Stand and standing long jump tests on two occasions separated by…

In recent years, numerous research studies have highlighted how teachers' perceptions of educational robotics (ER) and their sense of self-efficacy can influence the learning process. Although different instruments exist to investigate teachers' perspectives on ER, the Robotics Interest Questionnaire (RIQ) scale, developed within the Portuguese…

Past studies of grit's educational benefits, such as science engagement, showed mixed results across cultures. So, we elaborated the prior model of grit (perseverance of effort, consistency of interest) with "adaptability to situations" (forming a "triarchic model of grit" TMG), and tested TMG's relation to subsequent science…

Universal screening is one of the most-common topics and well-accepted best practices within the field of gifted and talented education. There appears to be little disagreement that universally screening all students as part of a gifted and talented identification process results in fewer missed students. But surprisingly, there is little guidance…

Student absenteeism is a persistent concern in K-12 education. Not only are the negative academic and social consequences of excessive absenteeism well documented, but states, districts, and schools are increasingly being held accountable for student attendance. As research indicates that disruptions in students' learning contexts may exacerbate…

Background: The Social Emotional Distress Scale-Secondary (SEDS-S) is a short measure designed for comprehensive school-based mental health screening, particularly for using very brief self-reported measures of well-being and distress. Whereas prior studies have shown validity and reliability evidence for the English version, there is a lack of…

This study evaluated the psychometric properties of the Hope-Action Inventory (HAI) scores with a problematic substance use population (N = 783). The hierarchical seven-factor structure of the HAI fit the data well. Further, the HAI scores had satisfactory internal consistency reliability and good convergent evidence for validity.

The purpose was to evaluate reliability of measurements during drop jump (DJ) and magnitude of differences in vertical jump height (VJH) when calculated using two variables: time-in-the-air and center-of-mass velocity. Thirty-seven handball players performed three single-leg and double-leg DJs on a portable force plate during two sessions. Sixteen…
