Even when raters demonstrate agreement in the use of a measure, limited score variability or violation of often-ignored statistical assumptions can result in lower reliability estimates than intuitively expected. This article uses data drawn from two randomized controlled trials of schema therapy and cognitive behavioral therapy for the treatment…

The broad autism phenotype is the phenotypic expression of the primary characteristics of autism. However, currently available tests do not agree with the two-domain operationalization of broad autism phenotype or autism, and their internal structure has shown instability across applications. This study presents the Broad Autism…

Purpose: The study was aimed at measuring farmers' helpline services quality in India using a standardized multi-factor scale (HELPQUAL) developed as part of this study. Design/methodology/approach: The present study is based on 360 farmers' and 45 experts' responses gathered using telephonic interviews and mailed questionnaires during the year…

The revised two-factor Study Process Questionnaire and the Approaches and Study Skills Inventory for Students are two instruments commonly used to measure student learning approach. Although they are designed to measure similar constructs, it is unclear whether the metrics they provide differ in terms of their real-world classification of learning…

Psychometric properties of the Survey of Perceived Organizational Support (SPOS-8) scores were examined with a national sample of school counselors (N = 1,005). SPOS-8 scores displayed good internal consistency ([alpha] = 0.92), one-factor structure, and convergent and discriminant validity. Measurement invariance was evident for White and…

Peer evaluation consists of the evaluation of students by their peers following criteria or rubrics provided by the teacher, where the way to evaluate students is specified so that they achieve the desired competencies. The quality of the measurement instrument must meet two essential criteria: validity and reliability. In this research, we…

We examined the performance of coefficient alpha and its potential competitors (ordinal alpha, omega total, Revelle's omega total [omega RT], omega hierarchical [omega h], greatest lower bound [GLB], and coefficient "H") with continuous and discrete data having different types of non-normality. Results showed the estimation bias was…

Student Evaluations of Teaching (SETs) gather crucial feedback on student experiences of teaching and learning and have been used for decades to evaluate the quality of teaching and student experience of instruction. In this paper, we make the case for an important improvement to the analysis of SET data that can further refine its interpretation.…

The Video Engagement Scale (VES) is a quality indicator to assess engagement in experimental video-vignette studies, but its measurement properties warrant improvement. Data from previous studies were combined (N = 2676) and split into three subsamples for a stepped analytical approach. We tested construct validity, criterion validity,…

Course design is critical to online student engagement and retention. This study focused on the development and validation of an online course design elements (OCDE) instrument with 38 Likert-type scale items in five subscales: (a) overview, (b) content presentation, (c) interaction and communication, (d) assessment and evaluation, and (e) learner…

Purpose: This article describes the development and initial validation of the Speech-Language Pathologist (SLP) Involvement in Multi-Tiered System of Supports (MTSS) Questionnaire. It was developed to measure the extent to which SLPs are involved in MTSS at their school site(s). Method: A total of 567 SLPs practicing in the United States responded…

This study developed a scale for evaluating how well students understand marine-resource conservation and sustainability; it evaluated the scale's psychometric properties and investigated the gender difference in the scale's score. We recruited 929 university students in Taiwan to answer a questionnaire developed using the scale. The scale's…

Researchers developed and initially validated a client-report measure of counselors' cultural humility, entitled the Cultural Humility and Enactment Scale (CHES). The sample includes 434 adults recruited from web-based surveys. Exploratory factor analyses were performed to examine the initial factor structure of the CHES. Bivariate correlations…

Plant awareness disparity (PAD, formerly plant blindness) is the idea that students tend not to notice or appreciate the plants in their environment. This phenomenon often leads to naïve points of view, such as plants are not important or do not do anything for humans. There are four components of PAD: attitude (not liking plants), attention (not…

Background: Autonomy support in people with intellectual disability (ID) is an important yet understudied topic. Psychometrically sound instruments are lacking. This study tested the factor structure and reliability of an instrument for assessing the extent people with intellectual disability perceive their support staff as autonomy supportive.…
