The extant literature regarding psychometric properties of measures of subclinical adult autism traits is sparse. The current study investigated the validity and internal consistency reliability of the 26-item Autism Quotient (AQ-26), a self-report measure of autism traits, in a nonclinical young adult sample. Results indicated significantly…

Leader self-efficacy (LSE) is a construct studied in adults and college students which is associated with leader emergence, individual performance, and group performance. However, to date, it has not been heavily examined in youth. Therefore, a five-item youth LSE scale was created which can aid in further research of this construct. This holds…

The purpose of this study was to examine construct validity of methods of calculating lexical diversity in written narrative samples relative to children's performance on a reading vocabulary measure. For 234 children in first to fifth grade, written narratives were examined and compared between grades for number of different words (NDW), total…

Objective: As eating disorders (EDs) often emerge during college, managing EDs would ideally integrate prevention and treatment. To achieve this goal, an efficient tool is needed that detects clinical symptoms and level of risk. This study evaluated the performance of a screen designed to identify individuals at risk for or with an ED.…

There currently exist no self-report measures of social camouflaging behaviours (strategies used to compensate for or mask autistic characteristics during social interactions). The Camouflaging Autistic Traits Questionnaire (CAT-Q) was developed from autistic adults' experiences of camouflaging, and was administered online to 354 autistic and 478…

The aim of this study is to investigate the reasons of the students' attitudes towards interactive whiteboard (IWB) use in mathematics classrooms in middle schools and high schools. For this purpose the effect of IWB's features, students' mathematics anxiety, teachers' ICT integration, students' mathematics achievement and gender to students'…

This study was primarily aimed at developing an English-speaking proficiency test and analytic rubrics designed to measure speaking proficiency of Malaysian undergraduates. On the basis of Littlewood's Methodological Framework and Long's Interaction Hypothesis, the researchers derived three speaking tasks from four sources: (a) syllabus of the…

Studies based on response processes of individuals can provide information that supports the assessment and increases the validity of the items in the scale or tests. The purpose of this study is to present the extent to which the student response processes are effective in identifying and developing the characteristics of the items in an…

The purpose of this study is to develop three scales to assess some features of a web-based monitoring and support system for internship processes of trainees which was named Monitoring and Support System (SIDES). These scales are: "SIDES Satisfaction Scale", "SIDES Acceptance Scale", and "SIDES Usability Scale". We…

Purpose: This study presents the competence level of education students in College Geometry and the development of a Computer Generated Instructional Materials (CGIM). Method: This research used the model for research and development by Borg and Gall (2003) with revision. The researchers developed a CGIM, specifically, the worktext paired with…

The purpose of this study was to develop and cross-validate a measurement scale on students' perception of a psychologically safe learning environment in the Turkish context. Primarily, the scale items underwent two rounds of expert review. Then, a series of item elimination or revisions were performed to improve their relevance to the content…

The purpose of the current study was to examine the validity and diagnostic accuracy of the "Intervention Selection Profile-Social Skills" (ISP-SS), a brief social skills assessment tool intended for use with students in need of Tier 2 intervention. Participants included 160 elementary and middle school students who had been identified…

We evaluate the predictive validity of the Massachusetts Candidate Assessment of Performance (CAP), a practice-based assessment of teaching skills that is typically taken during a candidate's student teaching placement and is a requirement for teacher preparation program completion in Massachusetts. We find that candidates' performance on the CAP…

The objective of this study was to examine the construct validity and bias of a child health interview (CHI) instrument to assess young children's food and activity preferences. A quantitative study examining the construct validity and bias of a young child health interview instrument using confirmatory factor analysis (CFA) and multi-group CFA…

Under the framework of item response theory (IRT) and generalizability (G-) theory, this study examined the effects of item difficulty on rating reliability and construct validity on both the constructed-response (CR) items and essay items on English examinations. The data collected for this study were students' scores and responses on the two…
