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…

This brief report presents interrater reliability data for the Focus on the Outcomes of Communication Under Six (FOCUS-34) between parents, and between parents and speech-language pathologists (SLPs). Reliability for all three raters combined was good to excellent across three assessments. Reliability for pairs of raters was variable but generally…

In this study, the assumption of the equality of psychological distance between categories of rating scale was tested based on the number of categories and ability distributions. Category parameters were estimated by using generalized partial credit model. The data sets based on the conditions of categories counts and ability distributions were…

This meta-analysis explores the correlation between self-assessment (SA) and language performance. Sixty-seven studies with 97 independent samples involving more than 68,500 participants were included in our analysis. It was found that the overall correlation between SA and language performance was 0.466 (p < 0.01). Moderator analysis was…

Introduction: The aim of this study is to validate a Spanish version of the Impact of Event Scale on People with ID (IES-ID). Methods: IES-ID was administered to adults with ID (n = 120), analyzing internal consistency, inter-rater and test-retest reliability, criterion validity, construct validity and feasibility. Results: Good internal…

Research on mixed devices in web surveys is in its infancy. Using a randomized experiment, we investigated device effects (desktop PC, tablet and mobile phone) for six response formats and four different numbers of scale points. N = 5,077 members of an online access panel participated in the experiment. An exact test of measurement invariance and…

This paper is an attempt to develop and validate the Emotional Competence Scale (ECS) in order to assess the emotional competence of upper primary school students. This review was done to find the dimensions that measure emotional competence. The dimensions are classified into two broad categories, such as personal competence and social…

With this article we aimed to contribute evidence on reliable and valid measurement of teacher resilience in an under-researched African context and population. Scales from an existing instrument, ENTREEi, were used to measure the resilience of pre-service teachers at a South African university. The sample constituted 1,193 final-year pre-service…

In this study, the concept of social media parenting (SMP) was defined and a scale was developed to measure parents' perceptions of SMP. Although SMP is referred to as "sharenting" in the literature, given that it has a much broader definition, an attempt was made to define it as a new concept that includes the concept of sharenting. The…
