OBJECTIVE To further validate the Child and Adolescent Scale of Environment (CASE). METHODS Baseline data (n = 430) were analyzed from a longitudinal study on quality of life for youth with chronic conditions ages 11-17 in Ontario, Canada. Internal consistency and structure, and convergent and discriminant validity were examined via Cronbach's alpha (α), exploratory factor analyses, correlati...

The Children's Eating Behaviour Questionnaire (CEBQ; Wardle, Guthrie, Sanderson, & Rapoport, 2001) is a widely used measure of child eating behaviors. Yet, only one study has examined the factor structure of the CEBQ among low-income children. In the current study, we examined the internal consistency, factor structure, and validity of the CEBQ among 1002 low-income preschool-age children recru...

The Gratitude Questionnaire (GQ; McCullough et al., 2002) is one of the most widely used instruments to assess dispositional gratitude. The purpose of this study was to validate a Chinese version of the GQ by examining internal consistency, factor structure, convergent validity, and measurement invariance across sex. A total of 1151 Chinese adults were recruited to complete the GQ, Positive Aff...

Teacher-education students attending a state university in the Southeastern United States responded to measures of Christian conservatism (theological fundamentalism and political evangelicalism) and sociopolitical values (e.g., nationalism, internationalism, patriotism, respect for civil liberties, and tolerance of dissent). Most of the measures demonstrated adequate internal consistency. Alth...

PURPOSE To compile and then validate a set of evidence-based best practices related to augmentative and alternative communication (AAC) and its role in fostering the inclusion of students with severe disabilities in general education classrooms and other inclusive settings. METHOD A comprehensive review of the literature pertaining to AAC and inclusive education for students with severe disab...

The development of a scale to measure perceived sources of academic stress among university students. Based on empirical evidence and recent literature review, we developed an 18-item scale to measure perceptions of academic stress and its sources. Experts (n = 12) participated in the content validation process of the instrument before it was administered to (n = 100) students. The developed in...

BACKGROUND Non-technical skills are critical for good anaesthetic practice but are not addressed explicitly in normal training. Realization of the need to train and assess these skills is growing, but these activities must be based on properly developed skills frameworks and validated measurement tools. A prototype behavioural marker system was developed using human factors research techniques....

We introduce a variational method for approximating distribution functions of dynamics with a “Liouville operator” L̂, in terms of a nonequilibrium action functional for two independent (left and right) trial states. The method is valid for deterministic or stochastic Markov dynamics, and for stationary or time-dependent distributions. A practical Rayleigh-Ritz procedure is advanced, whose input...

BACKGROUND Quality of recovery (QoR) after anesthesia is an important measure of the early postoperative health status of patients. The aim was to develop a short-form postoperative QoR score, and test its validity, reliability, responsiveness, and clinical acceptability and feasibility. METHODS Based on extensive clinical and research experience with the 40-item QoR-40, the strongest psychom...

The "Time trade-off" (TTO), is the most widely used method to "quality adjust" life years for "QALYs" in cost utility analysis. In this paper we ask if it is theoretically likely that the TTO is valid for this use. The TTO consists in a trade off between longevity and quality of life. Firstly, we argue that it is impossible to control for all factors that may influence one's willingness to sacr...
