Validity is an enduring theme in the information systems (IS) domain. However, because much of that discussion draws, at least nominally, on an Empiricist orientation, formulating issues of validity in a way that is pertinent to a practice-oriented discipline has been difficult. This is particularly true for external validity, which refers to the applicability, or relevance, of research to phen...

Pintrich & De Groot, 1990). Motivational components include students' perceptions of the classroom environment as well as their self-related beliefs such as personal goals, self-efficacy, interest, and value beliefs. Cognitive components include students' content knowledge as well as various cognitive learning strategies such as rehearsal, elaboration, and organization, and metacognitive strate...

BACKGROUND The Child Perceptions Questionnaire for children aged 11 to 14 years (CPQ11-14) is a 37-item measure of oral-health-related quality of life (OHRQoL) encompassing four domains: oral symptoms, functional limitations, emotional and social well-being. To facilitate its use in clinical settings and population-based health surveys, it was shortened to 16 and 8 items. Item impact and stepwi...

s this treatment effective? The best study to answer this question is a randomized controlled trial (RCT). Once a RCT is found to answer the therapeutic question of interest the reader must decide whether or not the authors took all of the important steps to minimize bias. The strength of the inference that we can take from the trial is based upon how well the authors have planned, executed and...

This paper proposes a research methodology, Lab-based Action Design Research, which combines organizational intervention (action research), building innovative artifacts (engineering research) and studies of software development practice (behavioral research) within a laboratory environment. Seven principles for successful Lab-based Action Design Research are proposed – attract funding with a w...

Cattle are considered one of the most important pillars of animal production in most countries of the world. As it being a building block in their national security strategies;endeavoring them to increase this animal population by all possible means. During the last three decades;it was clear thatin vitro maturation, fertilization and culturing of bovine oocytes are the most important of these ...

This research aimed at the evaluation of the psychometric properties of the Theory of Mind Assessment Scale (Th.o.m.a.s.). Th.o.m.a.s. is a semi-structured interview meant to evaluate a person's Theory of Mind (ToM). It is composed of several questions organized in four scales, each focusing on one of the areas of knowledge in which such faculty may manifest itself: Scale A (I-Me) investigates ...

This study examines the psychometric properties of the self-report version of the Inventory of Callous-Unemotional Traits in 191 detained female adolescents (M = 15.76, SD = 1.02). Evidence supporting the validity of the ICU scores was generally weak, largely due to poor functioning of the Unemotional subscale. Results from confirmatory factor analyses demonstrated support for a recently propos...

BACKGROUND The Job Content Questionnaire (JCQ), which is based on the Demand-Control-Support model, is designed to measure the psychosocial characteristics of the respondent's work, and has been identified to predict health and psychological outcomes. The purpose of this study was to investigate the psychometric properties of this instrument and the subsequent adaptation of its scales to the po...

While many studies have investigated the relationship between information systems (IS) characteristics and IS use, the results have been inconsistent. We argue that this inconsistency may be due to the modeling of information and system quality and the importance of the system usage context. We extend Wixom and Todd’s (2005) integrated model of IS satisfaction by proposing and modeling informat...
