Rasch validation of the Depression Scale among patients with low back pain.
2020
BACKGROUND: The Depression Scale (DEPS) is a commonly used screening tool for major depression in studies investigating low back pain, yet it has not been validated for patients with back-specific problems. OBJECTIVE: To assess the psychometric properties of the DEPS in patients with degenerative spinal disease. METHODS: Six hundred and thirty-seven patients with a degenerative spinal disease completed the DEPS instrument. The Rasch Measurement Theory was applied to analyze the measurement properties of the DEPS. The main hypothesis-driven approach was whether the DEPS would meet relevant psychometric criteria for assessing depressive symptoms among patients with degenerative spinal disease…
Development and validation of the EUROLIGHT questionnaire to evaluate the burden of primary headache disorders in Europe
2010
We developed a 103-item self-reporting questionnaire to assess the burden of primary headache disorders on those affected by them, including headache characteristics, associated disability, co-morbidities, disease-management and quality of life. We validated the questionnaire in five languages with 426 participants (131 in UK, 60 in Italy, 107 in Spain, 83 in Germany/Austria, and 45 in France). After a linguistic and a face-content validation, we tested the questionnaire for comprehensibility, internal consistency and test–retest reliability at an interval of one month. In the different countries, response rates were between 73% and 100%. Test–retest reliability varied between –0.27 to 1.0…
Psychometric Properties and factor structure of the spanish version of the HC-PAIRS questionnaire
2012
Objective To develop a Spanish version of the Health Care Providers" Pain and Impairment Relationship Scale (HC-PAIRS) and to test its psychometric properties. Methods A forward and backward translation methodology was used to translate the questionnaire, which was then applied to 206 participants (174physiotherapy students and 32 family physicians). The intraclass correlation coefficient was calculated to assess testretest reliability. Internal consistency was evaluated using Cronbach"s alpha and item analysis. Construct validity was measured using Pearson correlation coefficients between HC-PAIRS and FABQ, FABQ-Phys, FABQ-Work and the responses given by participants to three clinical case…
Development of a rating scale for quantitative measurement of the alcohol withdrawal syndrome
1992
The alcohol withdrawal syndrome consists of autonomic, neurological and mental symptoms. For its assessment, these symptoms have to be rated in a quantitative and valid manner. We developed a new rating scale for mild and moderate alcohol withdrawal states. Difficulty, discrimination coefficient, internal consistency, and the principal component analysis were assessed. External validation was tested on a separate sample of inpatients. Eight of 12 original items fulfilled test-the-oretical criteria. From these a psychosensory and an autonomic factor have been extracted. This instrument can be used repeatedly for clinical assessment as well as for evaluation of the alcohol withdrawal syndrome…
Childhood Neglect: Exploring a Short Questionnaire in Poland and Germany
2013
<b><i>Background:</i></b> Estimates about childhood abuse and neglect in various countries of the world indicate that cases of neglect outnumber cases of abuse by far. However, childhood neglect itself constitutes a neglected domain in psychological and medical research; far more articles have been published about abuse. <b><i>Sampling and Methods:</i></b> A ten-item questionnaire assessing childhood neglect was administered to two surveys in Poland (n = 508) and Germany (n = 500) via the internet. <b><i>Results:</i></b> Internal consistency was high in both countries, i.e. Cronbach's α was 0.82 in Poland and 0.88 in Ge…
Development, validation, and initial results of the Angioedema Activity Score
2013
Background Recurrent angioedema (RecA) is a frequent clinical problem characterized by suddenly occurring cutaneous and/or mucosal swellings. Depending on their location, RecA may be painful, hindering, disfiguring, or even life-threatening. The assessment of disease activity in affected patients is important to guide treatment decisions. Currently, however, there is no standardized and validated outcome measure available to do so. Objective To develop and validate the first specific patient-reported outcome instrument to assess disease activity in RecA patients, the Angioedema Activity Score (AAS). Methods After a set of potential AAS items was developed, item evaluation and reduction were…
Psychometric properties of 12-item self-administered World Health Organization disability assessment schedule 2.0 (WHODAS 2.0) among general populati…
2019
WHODAS 2.0 is a unified scale to measuring disability across diseases, countries, and cultures. The objective was to explore the available evidence on the psychometric properties of 12-item self-administered WHODAS 2.0 among a general population and people with non-acute physical causes of disability.Five databases Medline, Embase, Web of Science, Scopus, and PsycINFO were searched for papers related to the validity, reliability, responsiveness, minimal clinically important difference or minimal detectable change of 12-item self-administered WHODAS 2.0. In order to avoid missing any potentially relevant studies, the search clauses were left as generic as possible and the refining search was…
Modeling and Simulation as a Pedagogical and Heuristic Tool for Developing Theories in Cognitive Science: An Example from Ritual Competence Theory
2019
An interdisciplinary team of researchers in the fields of philosophy, religious studies, cognitive science, and computer science aimed to develop a computer model of ritual behaviour, based on McCauley and Lawson’s theory of ritual competence. That endeavour revealed some questions about the internal consistency and significance of the theory that had not previously been noticed or addressed. It also demonstrated how modeling and simulation can serve as valuable pedagogical and heuristic tools for better specifying theories that deal with complex social phenomena.
Search for neutral MSSM Higgs bosons at LEP
2006
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for the neutral Higgs bosons which are predicted by the Minimal Supersymmetric Standard Model (MSSM). The data of the four collaborations are statistically combined and examined for their consistency with the background hypothesis and with a possible Higgs boson signal. The combined LEP data show no significant excess of events which would indicate the production of Higgs bosons. The search results are used to set upper bounds on the cross-sections of various Higgs-like event topologies. The results are interpreted within the MSSM in a number of "benchmark" models, including CP-conserving and CP-violating scenarios. Thes…
Multi-model ensemble simulations of olive pollen distribution in Europe in 2014: current status and outlook
2017
"Çalışmada 29 yazar bulunmaktadır. Bu yazarlardan sadece Bursa Uludağ Üniversitesi mensuplarının girişleri yapılmıştır” The paper presents the first modelling experiment of the European-scale olive pollen dispersion, analyses the quality of the predictions, and outlines the research needs. A 6-model strong ensemble of Copernicus Atmospheric Monitoring Service (CAMS) was run throughout the olive season of 2014, computing the olive pollen distribution. The simulations have been compared with observations in eight countries, which are members of the European Aeroallergen Network (EAN). Analysis was performed for individual models, the ensemble mean and median, and for a dynamically optimised c…
