Objectives: Despite advances in understanding associations among attention-deficit hyperactivity disorder (ADHD), emotion dysregulation (ED), and related outcomes, there is incongruity between ADHD-relevant conceptualizations of ED and available measures of ED. To assess the psychometric properties of a parent-report questionnaire of ED…

Aim: To evaluate the psychometric properties of a new measure of school belonging. Rationale: The sense of belonging to the school (organisation) as opposed to individuals within a school (peers) plays a significant part in pupils' behaviour and wellbeing. To date, few psychometrically robust, theoretically driven and brief scales exist.…

The present study assesses the factor structure, psychometric adequacy, and invariance across sex and age of the Relational Provisions Loneliness Questionnaire (RPLQ). Discriminant validity with an external criterion was also tested. In a sample of Portuguese adolescents, from 7th to 9th grade (N = 817), Confirmatory Factor Analyses (CFA) were…

The purpose of this report is to describe the technical qualities of the 2018-2019 operational administration of the English language arts/literacy (ELA/L) and mathematics summative assessments in grades 3 through 8 and high school. The ELA/L assessments focus on reading and comprehending a range of sufficiently complex texts independently and…

New Meridian, in coordination with multiple states and vendors, developed an alternate form of the summative assessment to…

A new multidimensional measure of test anxiety, the Test Anxiety Measure for Adolescents (TAMA), specifically designed for U.S. adolescents in Grades 6 to 12 was developed and its psychometric properties were examined. The TAMA consists of five scales (Cognitive Interference, Physiological Hyperarousal, Social Concerns, Task Irrelevant Behavior,…

In two studies (ns = 312 and 1,149) with 9- to 12-grade students in pre-International Baccalaureate (IB) and IB Diploma programs, we evaluated the reliability, factor structure, measurement invariance, and criterion-related validity of the scores from the School Attitude Assessment Survey-Revised (SAAS-R). Reliabilities of the five SAAS-R subscale…

In two studies (ns = 312 and 1149) with 9-12 grade students in pre-International Baccalaureate (IB) and IB Diploma programs, we evaluated the reliability, factor structure, measurement invariance, and criterion-related validity of the scores from the School Attitude Assessment Survey-Revised (SAAS-R; McCoach & Siegle, 2003a). Reliabilities of…

Junior secondary school (grades 7 to 9) students (N?=?1,258) were invited to…

There is a lack of valid and reliable low cost observational instruments to measure moderate to vigorous physical activity (MVPA) in school physical education (PE). The participants in this study were third to tenth grade boys and girls from a south Texas school district. The SAM (Simple Activity Measurement) activity levels were compared with…

The authors aimed to propose a valid and reliable diagnostic instrument by developing a three-tier test on simple electric circuits. Based on findings from the interviews, open-ended questions, and the related literature, the test was developed and administered to 124 high school students. In addition to some qualitative techniques for…

The present study examined the validity of the Basic Empathy Scale (BES) [Jolliffe, D., & Farrington, D. P. (2006a). Development and validation of the Basic Empathy Scale. "Journal of Adolescence," 29, 589-611; Jolliffe, D., & Farrington, D. P. (2006b). Examining the relationship between low empathy and bullying. "Aggressive…

This study evaluated the psychometric properties of the Chinese version of the Social Anxiety Scale for Adolescents (SAS-A) in a sample of 296 adolescents (49% boys) in Grades 7, 8, 9, 10, and 12 with a mean age of 15.52 years. Confirmatory factor analysis replicated the three-factor structure of the SAS-A in the Chinese sample: Fear of Negative…

Self-determination theory provides an integrated conception of school- and academic motivation. The theory proposes a continuum comprising three types of motivation: intrinsic motivation (IM), extrinsic motivation (EM), and amotivation (AM), characterised by seven dimensions (IM = to know, to accomplish and to experience stimulation, EM = external…
