Background: Sensory irregularities are commonly seen across developmental and intellectual disability groups. Identifying patterns of dysfunction within these clinical groups facilitates the development of appropriate intervention strategies. Thus, we evaluated the psychometric properties of the new Sensory Processing (SP) Scale Inventory rating…

Background: Both parent-report and clinician-administered autism spectrum disorder (ASD) screening instruments are important to accurately inform ASD risk ascertainment. The aim of this study was to adapt a clinician-administered ASD screening instrument, the Autistic Behavioural Indicators Instrument (ABII), as a parent questionnaire equivalent…

The arrival of the Next Generation Science Standards (NGSS) marks a new era in science education. However, like all education reform, the success of NGSS implementation lies with teachers. Effective and targeted professional development will play a key role in preparing teachers who work from the framework. This study sought to design and validate…

This study was conducted for the purpose of developing an attitude scale in order to be able to measure the attitudes of students towards Islamic Law Lesson in a valid and reliable way. The sampling of the study consisted of 198 students who studied at 4th Grade at Cumhuriyet University, Faculty of Theology, and who answered the measurement scale.…

With the integration of technology in recent years, use of technology has rapidly increased in educational system, and has become almost a must rather than an option. The use of technology in educational processes accompanies some adaptation issues due to the nature of technology (rapid development, cost, need for electricity, change of roles,…

The aim of this study is to develop a five point likert scale called "Class Teachers' Perceived Self-efficacy in Creating an Effective Classroom Environment." Following this aim, a draft scale that included 44 items was developed and given to 248 class teachers working in Manisa and Usak cities of Turkey. The principal components…

In this study researchers aim to develop a valid and reliable talent management scale for educational organizations. For this aim the sample of the study involves 784 principals, vice principals and teachers who work in different schools and provinces in Istanbul in 2014-2015 academic year. Data was analyzed in eight steps by using quantitative…

Classification consistency and accuracy are viewed as important indicators for evaluating the reliability and validity of classification results in cognitive diagnostic assessment (CDA). Pattern-level classification consistency and accuracy indices were introduced by Cui, Gierl, and Chang. However, the indices at the attribute level have not yet…

Quantitative information about test score reliability can be presented in terms of the distribution of equated scores on an alternate form of the test for test takers with a given score on the form taken. In this paper, we describe a procedure for estimating that distribution, for any specified score on the test form taken, by estimating the joint…

The humble multiple-choice test is very widely used within education at all levels, but its susceptibility to guesswork makes it a suboptimal assessment tool. The reliability of a multiple-choice test is partly governed by the number of items it contains; however, longer tests are more time consuming to take, and for some subject areas, it can be…

Internists are required to perform a number of procedures that require mastery of technical and non-technical skills, however, formal assessment of these skills is often lacking. The purpose of this study was to develop, implement, and gather validity evidence for a procedural skills objective structured clinical examination (PS-OSCE) for internal…

Background: The Behaviour Problems Inventory-Short Form (BPI-S) is a spin-off of the BPI-01 that was empirically developed from a large BPI-01 data set. In this study, the reliability and factorial validity of the BPI-S was investigated for the first time on newly collected data from adults with intellectual disabilities. Methods: The sample…

This study reports on the psychometric evaluation of the Chinese version of the Homework Management Scale (HMS). The HMS was designed to assess students' homework management strategies. Based on a randomized split of 884 high school students in China, we conducted exploratory factor analysis on Group 1 (n = 442) and confirmatory factor analysis on…
