Multidimensional assessment of OCD: integration and revision of the Vancouver Obsessional-Compulsive Inventory and the Symmetry Ordering and Arrangin…
2010
This article reports on the integration and revision of two self-report measures of obsessive-compulsive symptoms based on data from an obsessive-compulsive disorder (OCD) sample (n=228): the Vancouver Obsessional-Compulsive Inventory (VOCI) and the Symmetry Ordering and Arranging Questionnaire (SOAQ). The revised measure provides scores on five symptom subscales (Contamination, Checking, Hoarding, Symmetry and Ordering, Obsessions). It shows improvement upon current versions in several ways: it has a good model fit, eliminates redundancy, reduces overlap across subscales, is much shorter, and covers those OCD dimensions most frequently identified in factor-analytic studies. Strengths of th…
A new mucosal propeller flap (Deep Lingual Artery Axial Propeller): The renaissance of lingual flaps
2015
BACKGROUND: Lingual flaps provide ideal mucosal coverage for intraoral defects but traditionally require two surgical stages. The authors present an axial mucosal propeller flap for single-stage intraoral reconstruction. The flap includes the mucosa of the lateral side of the tongue, islanded on the deep lingual vessels. METHODS: Between 2011 and 2013, 23 patients underwent intraoral mucosal reconstruction with a deep lingual artery axial propeller flap after cancer resection in the cheek (n = 16), floor of the mouth (n = 2), retromolar trigone (n = 2), hard palate (n = 2), and soft palate (n = 1). Mean defect size was 19.5 cm. Preoperative and postoperative intraoral function was evaluated…
The symptom check-list, SCL-90-R: its use and characteristics in chronic pain patients
2000
The SCL-90-R is a widely-used questionnaire for self-report of psychological distress and multiple aspects of psychopathology, as part of the evaluation of chronic pain patients and other non-psychiatric populations. The aim of this study is the presentation of clinical results of this multidimensional questionnaire in a convenience sample of 3540 chronic pain patients treated in a multidisciplinary pain centre. Confirmatory Factor Analysis (CFA), Exploratory Factor Analysis (EFA), single scale factor analyses and Cronbach's alphas are used to assess the internal structure and correlation to other instruments (CES-D, STAI, MPSS) to assess construct validity. It is shown that the 9 dimension…
A confirmatory factor analytic validation of the Tinnitus Handicap Inventory
2015
Abstract Objective Because the postulated three-factor structure of the internationally widely used Tinnitus Handicap Inventory (THI) has not been confirmed yet by a confirmatory factor analytic approach this was the central aim of the current study. Methods From a clinical setting, N = 373 patients with chronic tinnitus completed the THI and further questionnaires assessing tinnitus-related and psychological variables. In order to analyze the psychometric properties of the THI, confirmatory factor analysis (CFA) and correlational analyses were conducted. Results CFA provided a statistically significant support for a better fit of the data to the hypothesized three-factor structure ( RMSEA…
Brief assessment of subjective health complaints: Development, validation and population norms of a brief form of the Giessen Subjective Complaints L…
2017
Abstract Objective Although there is no causal relationship to medical morbidity, routine clinical assessment of somatic symptoms aids medical diagnosis and assessment of treatment effectiveness. Regardless of their causes, somatic symptoms indicate suffering, distress, and help-seeking behavior. The aim of the present study was to develop and validate a brief self-report questionnaire to assess somatic symptom strain. Methods A brief form of the Giessen Subjective Complaints List (GBB-8) was developed and validated in a large population sample representative of the Federal Republic of Germany ( N = 2008). Psychometric analyses included confirmation of factor structure, classical item anal…
Barriers to physical activity in coronary artery disease patients: Development and validation of a new scale
2017
Abstract Objective To develop and validate a self-report questionnaire to measure barriers to regular physical activity (PA) in patients with stable coronary artery disease (CAD). Methods Phase 1: 17 patients completed a semi-structured interview. After grouping and reformulating the reported barriers, their pertinence was reevaluated by the patients. Then, a decision algorithm was used to select items. A principal component analysis was performed to determine content validity. Phase 2: 49 patients completed the questionnaire resulting from phase 1 twice, 7 days apart, and questionnaires to evaluate depression, anxiety, and the level of physical activity. Construct validity was evaluated by…
Psychometric evaluation of the Persian version of the diabetic foot self-care questionnaire in Iranian patients with diabetes
2021
AbstractBackgroundDiabetic foot self-care refers to a group of self-management behaviors that can reduce the incidence of foot ulcers and amputations. It is necessary to have a valid and reliable standard tool to measure foot self-care in diabetic patients. This study aimed to evaluate the psychometric properties of the Persian version of the Diabetic Foot Self-Care Questionnaire of the University of Malaga, Spain (DFSQ-UMA) in Iran.MethodsThis cross-sectional study was conducted with 407 diabetic patients who were selected using a convenient sampling method. Construct validity was assessed by exploratory (with 207 patients) and confirmatory (with 200 patients) factor analyses. Internal con…
Validation of the oral health impact profile - 14 in patients with head and neck cancer
2020
Background The Oral Health Impact Profile-14 (OHIP-14) was designed to assess patients’ perception of the impact of oral disorders on their quality of life (QoL). Although the OHIP-14 is now frequently used in patients with head and neck cancer, data related to its measurement properties in this population are scarce. The aim of the present study was to evaluate the reliability and validity of the OHIP-14 in a sample of Serbian patients with head and neck cancer. Material and Methods Data were available for 345 patients (257 [74.5%] males; aged 30-92 years), with head and neck cancer. All patients completed the OHIP-14 and the European Organization for Research and Treatment of Cancer (EORT…
Assessment of Construct Validity of the Oswestry Disability Index and the Scoliosis Research Society–30 Questionnaire (SRS-30) in Patients With Degen…
2019
Observational cohort study.To measure and compare the structural validity of the Oswestry Disability Index (ODI) and the Scoliosis Research Society-30 (SRS-30) questionnaire in an adult population with prolonged degenerative thoracolumbar disease.The ODI and the SRS-30 are commonly used patient-reported outcome instruments to assess back-specific disability and symptoms related to scoliosis. Still, these instruments have not been validated for degenerative spinal disease with different stages of deformity.Altogether, 637 consecutive adult patients with degenerative spinal pathologies were included. The patients completed the ODI (version 2.0), the 23 preoperative items of the SRS-30, a gene…
Reverse Homodigital Dorsal Radial Flap of the Thumb.
2006
BACKGROUND: Reconstruction of extensive distal defects of the thumb with exposure of bone, tendon, or joint can be a difficult problem because immediate closure is of paramount importance for preserving function and avoiding complications. Surgical treatment includes the use of local, reverse flow, and free flaps. The authors describe a new reverse homodigital flap to repair distal defects of the thumb. This flap is raised from the dorsal radial side of the first metacarpal area. It is pedicled on the dorsal radial collateral artery, which is constant for course, caliber, and communication with the palmar circuit. METHODS: The flap is raised by means of distal to proximal dissection, the sk…
