This study examined the reliability and difficult indices of Multiple Choice (MC) and True or False (TF) types of objective test items in a Mathematics Achievement Test (MAT). The instruments used were two variants- 50-items Mathematics achievement test based on the multiple choice and true or false test formats. A total of five hundred (500)…

Purpose: To continue the development of a quantified, standard method to differentiate individuals with stroke and dysphagia from individuals without dysphagia. Method: Videofluoroscopic swallowing studies (VFSS) were completed on a group of participants with acute stroke (n = 42) and healthy age-matched individuals (n = 25). Calibrated liquid…

Public debates about socioscientific issues are increasingly prevalent, but the public response to messages about, for example, climate change, does not always seem to match the seriousness of the problem identified by scientists. Is there anything unique about appeals based on scientific evidence--do people evaluate science and nonscience…

The current study had two main purposes. The first was to develop and validate an instrument to measure emotional labor among teachers (Teacher Emotional Labor Scale, TELS) with an emphasis on the emotion regulation strategies during critical work events. The second was to investigate whether emotional deviance could be considered as one of the…

A valid and reliable instrument for measuring affect intensity does not exist for adolescents; such a measure may help to refine understanding of emotion among youths. The purpose of the current study was to evaluate the psychometric properties and clinical relevance of a measure of affect intensity adapted for youths. Two hundred five community…

This study applied generalizability theory to investigate the interrater reliability of a team-scored electronic portfolio required for initial teacher certification. The sample consisted of 31 preservice teacher portfolios which were assigned to three groups of portfolio review teams. The review teams, which had received several rounds of…

Cross-cultural research in many psychology-related fields is becoming commonplace. To further the research in a methodologically rigorous fashion it is critical to be able to measure adequately the constructs under investigation. This study (N = 238) examined three measures used to assess individualist and collectivist orientations. The internal…

Children's versions of the Empathy Quotient (EQ-C) and Systemizing Quotient (SQ-C) were developed and administered to n = 1,256 parents of typically developing children, aged 4-11 years. Both measures showed good test-retest reliability and high internal consistency. As predicted, girls scored significantly higher on the EQ-C, and boys scored…

This article concerns a parent-report repeat questionnaire to evaluate the quality of multiprofessional early intervention following early identification of deafness. It discusses the rationale for the design of the instrument, its theoretical underpinnings, its psychometric properties, and its usability. Results for the validity and reliability…

This study aimed to investigate the underlying components constituting the extended version of the ICT Indicators Measurement Scale (ICTIMS), which was developed in 2007, and extended in the current study through the addition of 34 items. New items addressing successful ICT integration at education faculties were identified through the examination…

This study examined divergent thinking (DT) test scores of applicants taking part in a selection procedure for an undergraduate psychology degree (N = 370). Interviewers made six specific (creative intelligence, motivation, work habits, emotional stability, sociability, and social responsibility) and one overall recommendation rating on each…

Purpose: This study aimed to investigate (a) the accuracy of adult reports in assessing the vocabulary knowledge of Cantonese-speaking children with hearing impairment (HI) and (b) the factors that are associated with the accuracy of those reports. Method: The first participant group consisted of 47 children and their mothers. The second group…

This study was undertaken to determine the level of understanding of Gold Coast general practitioners (GPs) pertaining to such criteria as reliability, interactive and usability components associated with health websites. These are important considerations due to the increased levels of computer and World Wide Web (WWW)/Internet use and health…

Reliability captures the influence of error on a measurement and, in the classical setting, is defined as one minus the ratio of the error variance to the total variance. Laenen, Alonso, and Molenberghs ("Psychometrika" 73:443-448, 2007) proposed an axiomatic definition of reliability and introduced the R[subscript T] coefficient, a measure of…

Numerous studies have pointed to a gap between the attitudes people express about the natural environment and their subsequent behaviors toward that environment. Variables identified within these studies include: how significant others view behaviors related to the attitudes; demographic variables such as sex, age or education; self-perceived…
