This paper studies test-retest reliability and validity of one measure of adolescent health complaints. The test-retest included an eight-item symptom checklist developed for the survey of Health Behaviour in School-aged Children (n=344). Qualitative analysis showed adequate validity for most items. For the total sample, all items were found to have adequate intraclass correlation coefficients ...

retest scans (MRS 2 & MRS 3) following a cognitive challenge task; B. Placement of the voxel-of-interest in the ACC; C. Examples of metabolite concentrations across three within subject scanning sessions for Cr and NAA and; D. Variation around the mean of each metabolite as a function of test-retest (yellow bars) and inter-subject (blue bars) variability. The numbers on the blue bars are the in...

To translate and culturally adapt the Patient Observer Scar Assessment Scale, POSAS, to Norwegian explore its test-retest, intra- inter-tester reliability. POSAS was translated into following international guidelines in collaboration with an translation bureau. Twenty-six adults 24 children were recruited from a burns outpatient clinic. Three observer-categories: doctor, nurse physiotherapist, ...

BACKGROUND Research has identified stigmatization as a major threat to successful treatment of individuals with mental illness. As a consequence several anti-stigma campaigns have been carried out. The results have been discouraging and the field suffers from lack of evidence about interventions that work. There are few reports on psychometric data for instruments used to assess stigma, which t...

Galactomannan enzyme immune assay (GM EIA) is a nonculture test for detecting invasive aspergillosis (IA) forming a key part of diagnosis and management. Recent reports have questioned the reproducibility of indices after sample storage. To investigate this, 198 serum samples (72 from cases and 126 from controls) and 61 plasma samples (24 from cases and 37 from controls), initially tested betwe...

The goal of the study was to assess the test-retest reliability of the Work Ability Index (WAI) questionnaire. Reliability was tested using a test-retest design with a 4 week interval between measurements. Valid data were collected among 97 elderly construction workers aged 40 years and older. We analysed the test-retest reliability of the WAI score itself (range 7-49 points) and classification...
