BACKGROUND Economic environmental factors represent important barriers to participation and have deleterious effects on quality of life (QOL) in persons with spinal diseases (SpD). While economic factors are anchored in the International Classification of Functioning, Disability and Health, their influence on QOL and participation from patients' perspectives is an infrequent focus of research. ...

Self-assessment is an appropriate way to support client-centered practice and promote personal development in young occupational therapy clients. This study, the second study in a series of two, sought to refine the psychometric properties based on previous analysis of the Child Occupational Self-Assessment (COSA), a self-report tool based on the Model of Human Occupation. The COSA comprises 24...

BACKGROUND The Pediatric Quality of Life Inventory (PedsQL) is a child self-report and parent proxy-report instrument designed to assess health-related quality of life (HRQOL) in healthy and ill children and adolescents. It has been translated into over 70 international languages and proposed as a valid and reliable pediatric HRQOL measure. This study aimed to assess the psychometric properties...

In this study, construct validity of 2 pain behaviour observation measurement instruments for young children aged 1 to 56 months (mean age was 20 months) with burns is assessed by using Rasch analysis. The Rasch model, wherein data should meet the model expectations, assumes that an instrument measures one unidimensional construct, and focuses on the items of measurement instruments. The Pain O...

The prevalence of attention-deficit/hyperactivity disorder (ADHD) has been estimated at 3-7% in the population. Children with this disorder are often characterized by symptoms of inattention and/or impulsivity and hyperactivity, which can significantly impact on many aspects of their behaviour and performance. This study investigated the characteristics of the SWAN Rating Scale and its discrimi...

A new measure for reliability of a rating scale is introduced, based on the classical definition of reliability, as the ratio of the true score variance and the total variance. Clinical trial data can be employed to estimate the reliability of the scale in use, whenever repeated measurements are taken. The reliability is estimated from the covariance parameters obtained from a linear mixed mode...

BACKGROUND Aimed to develop a unitary scoring system for the 'Health Behaviour in school-aged Children' (HBSC) symptom checklist that would facilitate cross-national comparisons and interpretation. Rasch measurement analysis and investigation of differential item functioning (DIF) were conducted. METHODS Data were obtained from the 'WHO collaborative study HBSC 2001/2002'. A total of 162,305 ...

The present work presents two exploratory studies about the construction and validation of the Inductive Reasoning Developmental Stage (IRDT), a forty-eight items test based on the Model of Hierarchical Complexity. The first version of the test was administered to a convenience sample composed by 167 Brazilian people (50.3% men) aged between 6 to 58 years (M = 18.90, SD = 9.70). The Rasch Model...

Research skills are one of the that need to be built for students face challenges 21st Century. Therefore, this study aims build research through Collaborative Real-World Analysis (CReW-A) learning model. This uses One-Shot Case Study design. Respondents came from 21 Physics Education who were grouped into seven groups. observed using a 5-point Likert rating scale observation sheet. Students an...
