Reliability indicates the internal consistency of a test. In educational studies, reliability is a key feature for a test. Researchers have proposed many traditional reliability estimates, such as coefficient alpha and coefficient omega. However, traditional reliability indices do not deal with the data hierarchy, even though the multilevel…

The instrument that assesses teachers' competence on AR methodology is limited. Thus, it is one of the issues concerning evaluating the effectiveness of a professional development program on designing AR projects. It is difficult to determine how much and what teachers have learned in a course or training. Thus, this cross-sectional study aimed to…

The purpose of this study is to develop a five-point Likert scale called 'Curriculum Fidelity'. For this purpose, a draft scale consisting of 65 items have been represented to the expert opinion firstly and it has been decided that 15 items should be excluded. The remaining 50 items have been given to 249 teachers and the maximum likelihood has…

In the current study, we aimed to develop a reliable and valid scale to address individual cognitive load types. Existing scale development studies involved limited number of items without adequate convergent, discriminant and criterion validity checks. Through a multistep correlational study, we proposed a three-factor scale with 13 items to…

We examined the construction for a modified Acceptance of Couple Violence (ACV) scale administered to lesbian, gay, bisexual, transgender, and queer college students (N = 266) measuring intimate partner violence. We ran an exploratory and confirmatory factor analysis; results identified 1 factor for the instrument explaining 76% of the variance in…

The Diagnostic Assessment and Achievement of College Skills (DAACS) online system assesses newly enrolled college students' skills in reading, writing, mathematics, and self-regulated learning, and provides individualized feedback and links to resources. The purpose of this study is to examine validity evidence regarding the internal structure of…

Objective: To examine the psychometric properties of a measure of cannabis-specific Protective Behavioral Strategies (PBS), which assesses ways in which students may reduce cannabis-related risk. Participants: Respondents to the American College Health Association-National College Health Assessment II (N = 580) during Spring 2015. Methods:…

Objective: Using a 4-phase study design, the present study developed and tested the Charlotte Attitudes Towards Sleep (CATS) Scale, a measurement tool for assessing sleep attitudes in college students. Participants: Participants were 706 undergraduate students recruited at a southeastern university and on a national recruitment Web site between…

We examined the psychometric properties of the Short Grit Scale with a sample of school counselors. The confirmatory factor analysis resulted in a modified 2-factor solution and internal reliability estimates were satisfactory. Furthermore, participants' grit inversely correlated with their stress and burnout. We discuss the implications of these…

One out of every three students who begin an academic school year does not return for a second year, which has remained unchanged for the past 50 years. The Seven Principles for Good Practice in Undergraduate Education could improve the classroom learning environment, which could lead to increased student satisfaction and retention. More empirical…

This study examined the factor structure, reliability, and validity of the first part of the Chinese version of the CRIME-PICS II Scale, a self-administrated instrument assessing offending-related attitudes. Data were collected from three samples: male Hong Kong young offenders, female Mainland Chinese prisoners, and Hong Kong college students.…

The growth of Smartphone usage, increased acceptance of electronic learning (E-learning), the availability of high reliability mobile networks and need for flexibility in learning have resulted in the growth of mobile learning (M-learning). This has led to a tremendous interest in the acceptance behaviors related to M-learning users among the…

Certain diversity among team members is beneficial to the growth of an organization. Multiple measures have been proposed to quantify diversity, although little is known about their psychometric properties. This article proposes several methods to evaluate the unidimensionality and reliability of three measures of diversity. To approximate the…

This study evaluated the factorial structure of the Pedagogical and Social Climate in School (PESOC) questionnaire among 307 teachers in Bulgaria. The teacher edition of PESOC consists of 11 scales (i.e., Expectations for Students, Unity Among Teachers, Approach to Students, Basic Assumptions About Students' Ability to Learn, School-Home…

Introduction: The Approaches and Study Skills Inventory for Students (ASSIST Short Version) was used to better understand the students' approaches to learning in a mathematics classes.
