Evaluators are often called upon to assess the effects of programs. To assess a program effect, evaluators need a clear understanding of how a program effect is defined. Arguably, the most widely used definition of a program effect is the counterfactual one. According to the counterfactual definition, a program effect is the difference between…

Purpose: The purpose of this paper is to develop a reliable and valid measurement scale of employee engagement that can be used in human resources departments in any industry field. Design/methodology/approach: This study used the measurement development process with three steps. The first step was to generate items for measuring employee…

Replication studies are uncommon in education, and replications of validation studies are rarer. This study aimed to replicate, reproduce, and expand the study by Jellicoe and Forsythe published in 2019 that validated the Feedback in Learning Scale. We followed the original procedures, conducting a full validation process. We found only an 87%…

This study aimed to determine the validity of the ActiGraph wGT3X-BT for step counts (SC) at five different body locations in laboratory settings. A total of 29 male adults participated in this study. The participants walked or ran for different speeds on the treadmill while wearing ActiGraph wGT3X-BT on their right wrist (RW), left wrist (LW),…

Systematic reviews and meta-analyses are essential for drawing conclusions regarding etiologic associations between exposures or interventions and health outcomes. Observational studies comprise a substantive source of the evidence base. One major threat to their validity is residual confounding, which may occur when component studies adjust for…

Objective: The purpose of this study was to determine whether the Exercise Motivations Inventory -- 2 (EMI-2) scale would be appropriate to measure college students' exercise motivation. Participants: The EMI-2 scale questionnaire was administered to 325 college students in the southwestern U.S. Method: The WINSTEPS program was conducted to…

Meta-analysis was used to examine curriculum-based measurement in the content areas of social studies and science. Nineteen studies between the years of 1998 and 2020 were reviewed to determine overall mean correlation for criterion validity and examine alternate-form reliability and slope coefficients. An overall mean correlation of 0.59 was…

The possible dependency of criterion validity on item formulation in a multicomponent measuring instrument is examined. The discussion is concerned with evaluation of the differences in criterion validity between two or more groups (populations/subpopulations) that have been administered instruments with items having differently formulated item…

The Stranger Face Trust (SFT) questionnaire and the Imaginary Stranger Trust (IST) questionnaire are two new self-report measures of generalized trust that assess trust in real (SFT) and imaginary (IST) strangers across four trust domains. Both were designed to be objective, empirically valid, and easy to administer and score. To assess…

Many mathematics departments have transition to proof (TTP) courses, which prepare undergraduate students for proof-oriented mathematics. Here we discuss how common TTP textbooks connect three topics ubiquitous to such courses: logic, proof techniques, and sets. In particular, we were motivated by recent research showing that focusing on sets is…

Previous research in mathematics education has explored teachers' conceptions of mathematics and its teaching and learning, and how their instructional tendencies (e.g., "traditional", "technological", "spontaneous" and "investigative") relate to these conceptions. However, empirical evidence on this topic…

Sensory issues are highly prevalent in autism and previous findings support a relationship between questionnaires of sensitivity and autistic symptoms and traits, whereas studies that examine this relationship through behavioural assessments of sensitivity are less consistent. The current study explores these differences and suggests that…

We report a Delphi Consensus modification and first validation study of the Autism Diagnostic Observation Schedule -- 2 with deaf children and young people (ADOS-2 Deaf adaptation). Validation included 122 deaf participants (aged 2-18 years), 63 with an Autism Spectrum Disorder (ASD). This was compared to a National Institute for Health and…

A negative association between symptoms of teacher burnout (e.g., emotional exhaustion) and students' academic outcomes has been demonstrated in previous research. Although, in theoretical models, it has been suggested that this association can be explained through changes in teachers' instructional behavior, these mediating processes have not yet…

Objective: Currently, no clinically feasible objective measures exist that are specific to the signs of adductor laryngeal dystonia (LD), deterring effective diagnosis and treatment. This project sought to establish concurrent validity of a new automated acoustic outcome measure, designed to be specific to adductor laryngeal dystonia (AdLD): the…
