Psychometric properties of the updated EORTC module for assessing quality of life in patients with lung cancer (QLQ-LC29): an international, observat…
2020
Abstract: Background The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Lung Cancer 13 (QLQ-LC13) assesses quality of life (QOL) in patients with lung cancer and was the first EORTC module developed for use in international clinical trials. Since its publication in 1994, major treatment advances with possible effects on QOL have occurred. These changes called for an update of the module and its international psychometric validation. We aimed to investigate the scale structure and psychometric properties of the updated lung cancer module, QLQ-LC29, in patients with lung cancer. Methods This international, observational field study was done in…
Temporal abnormalities in children with developmental dyscalculia.
2012
Recent imaging studies have associated Developmental dyscalculia (DD) to structural and functional alterations corresponding Parietal and the Prefrontal cortex (PFC). Since these areas were shown also to be involved in timing abilities, we hypothesized that time processing is abnormal in DD. We compared time processing abilities between 10 children with pure DD (8 years old) and 11 age-matched healthy children. Results show that the DD group underestimated duration of a sub-second scale when asked to perform a time comparison task. The timing abnormality observed in our DD participants is consistent with evidence of a shared fronto-parietal neural network for representing time and quantity.…
Structural validity of the Finnish Manchester-Oxford Foot Questionnaire (MOXFQ) using the Rasch model.
2019
Background: The 16-item patient-reported Manchester-Oxford Foot Questionnaire (MOXFQ) with subscales of pain, social interactions, and walking/standing has been claimed for strongest scientific evidence in measuring foot and ankle complaints. This study tests the validity of the Finnish MOXFQ for orthopaedic foot and ankle population using the Rasch analysis. Methods: We translated the MOXFQ into Finnish and used that translation in our study. MOXFQ scores were obtained from 183 patients. Response category distribution, item fit, coverage, targeting, item dependency, ability to measure latent trait (unidimensionality), internal consistency (Cronbach's alpha), and person separation index (PS…
Amalgam fillings and cognitive abilities in a representative sample of the elderly population.
2000
Objectives: The ongoing controversial discussion about a possible negative effect of amalgam fillings on the cognitive abilities and the pathogenesis dementia was the objective of the present study. Sample: A total of 300 patients aged from 70 to 103 years were selected from the multidisciplinary ‘Berlin Aging Study’ (Base). The sample was heterogeneous concerning lifestyle, education and social prestige. According to their dental state subjects were allocated into three groups: edentate ≥20 years (I) and residual teeth without (II) or with (III) amalgam restorations. All groups were matched for age and gender. Design: Dental examinations and various psychiatric as well as psychological ass…
Non-infectious uveitis burden on quality of life and work impairment assessed through different psychometric questionnaires
2021
Background: The purpose of this study was to evaluate the association between a novel psychometric 12-item questionnaire (U-qest) and other validated questionnaires to assess quality of life and work impairment in patients with non-infectious uveitis. Methods: Data were collected at baseline and 3 months postbaseline using U-qest and two other validated questionnaires: The National Eye Institute 25-Item Visual Function Questionnaire (VFQ-25) and the 12-Item Short-Form Health Survey (SF-12). Results: A total of 136 patients (52.2% female) aged 47.9 ± 14.8 years (mean ± SD) were enrolled in 14 uveitis referral centres. U-qest correlated moderately with VFQ-25 and SF-12 at baseline and at 3 mo…
Quality of life and functional limitations after pulmonary embolism and its prognostic relevance
2019
Abstract Background While the importance of patients’ quality of life (QoL) in chronic cardiac or pulmonary disease is uncontroversial, the burden of an acute pulmonary embolism (PE) on QoL has received little attention thus far. Objectives We aimed to validate the German PEmb‐QoL questionnaire, identify associations between QoL and clinical/functional parameters, and investigate the prognostic relevance of QoL for long‐term survival in survivors of an acute PE episode. Patients/Methods Patients were invited for a clinical follow‐up visit including assessment of QoL using the German PEmb‐QoL questionnaire 6 months after an objectively confirmed PE at a single center. Internal consistency re…
Comparing 15D and SF-6D Performance in Fragility Wrist and Hip Fracture Patients in a Two-Year Follow-Up Case-Control Study
2012
Accepted version of an article in the journal:Value in Health. Published available from Elsevier on Science Direct: http://dx.doi.org/10.1016/j.jval.2012.08.2200 Objectives To examine and compare the two utility and health-related quality-of-life (HRQOL) measures 15D and (SF-6D) in fragility wrist and hip fracture patients and controls, study the responsiveness of 15D and SF-6D, and examine the impact of these fractures on changes in 15D and SF-6D scores over 2 years. Methods A total of 152 wrist fracture patients and 164 controls and 61 hip fracture patients and 61 controls with 15D and SF-6D scores were studied. Results The mean 15D score decreased significantly in wrist fracture patients…
Reliability and validity of the Finnish version of the prosthesis evaluation questionnaire
2018
Background: Thus far there have been no specific patient-reported outcome instrument in Finnish for health-related quality of life (HRQoL) assessment after major lower extremity amputation and successful prosthesis fitting. Methods: The prosthesis evaluation questionnaire (PEQ) was translated and cross-culturally adapted into Finnish. Participants completed a questionnaire package including the Finnish version of the PEQ and the 15 D HRQoL instrument. Scales (n = 10) were tested for internal consistency, floor-ceiling effect, and reproducibility for which participants completed the PEQ twice within a 2-week interval. Validity was tested by estimating the correlation between the 15 D index a…
Positive and Negative Affect Schedule (PANAS): psychometric properties of the online Spanish version in a clinical sample with emotional disorders
2020
Abstract Background The Positive and Negative Affect Schedule (PANAS) is the most widely and frequently used scale to assess positive and negative affect. The PANAS has been validated in several languages, and it has shown excellent psychometric properties in the general population and some clinical samples, such as forensic samples, substance users, and adult women with fibromyalgia. Nevertheless, the psychometric properties of the scale have not yet been examined in clinical samples with anxiety, depressive, and adjustment disorders. In addition, the proliferation of Internet-based treatments has led to the development of a wide range of assessments conducted online with digital versions …
Validity of five foot and ankle specific electronic patient-reported outcome (ePRO) instruments in patients undergoing elective orthopedic foot or an…
2019
Background: Patient-reported outcomes (PROS) are widely accepted measures for evaluating outcomes of surgical interventions. As patient-reported information is stored in electronic health records, it is essential that there are valid electronic PRO (ePRO) instruments available for clinicians and researchers. The aim of this study was to evaluate the validity of electronic versions of five widely used foot and ankle specific PRO instruments. Methods: Altogether 111 consecutive elective foot/ankle surgery patients were invited face-to-face to participate in this study. Patients completed electronic versions of the Foot and Ankle Ability Measure (FAAM), the Foot and Ankle Outcome Score (FAOS),…
