The Childhood Asperger Syndrome Test (CAST) is a 37-item parental self-completion questionnaire to screen for autism spectrum conditions in research. Good test accuracy was demonstrated in studies with primary school aged children in mainstream schools. The aim of this study was to investigate the test-retest reliability of the CAST. Parents of 1000 children in years 1-6 in five mainstream prim...

BACKGROUND The Mobile Application Rating Scale (MARS) provides a reliable method to assess the quality of mobile health (mHealth) apps. However, training and expertise in mHealth and the relevant health field is required to administer it. OBJECTIVE This study describes the development and reliability testing of an end-user version of the MARS (uMARS). METHODS The MARS was simplified and pil...

The mechanisms underlying hemispheric specialization of memory are not completely understood. Functional magnetic resonance imaging (fMRI) can be used to develop and test models of hemispheric specialization. In particular for memory tasks however, the interpretation of fMRI results is often hampered by the low reliability of the data. In the present study we therefore analyzed the test-retest ...

AIM To develop and psychometrically test the self-efficacy and performance in self-management support (SEPSS) instrument. BACKGROUND Facilitating persons with a chronic condition to take an active role in the management of their condition, implicates that nurses acquire new competencies. An instrument that can validly and reliably measure nurses' performance and their perceived capacity to pe...

OBJECTIVE To determine the relationship between mobility performance measures and Wheelchair Skill Test (WST) scores and to establish the test-retest and inter-rater reliability of these measures. METHODS Forty patients with spinal cord injury participated in this study. Subjects performed the Wheelchair Skill Test and mobility performance tests: maximal velocity (Vmax), spontaneous velocity ...
