Confirmatory factor analysis and psychometric properties of the Yale–Brown–Cornell Eating Disorders Scale Self-Report version (SR-YBC-EDS) in Spanish…
2015
[EN] Objective: The aimof the study was to adapt and validate the Yale Brown Cornell Eating Disorder Scale (YBC-EDS) transformed into a self-report format in Spanish clinical and non-clinical samples. Method: Eighty-three eating disordered patients and 358 non-clinical participants completed the Self Report-YBCEDS version (SR-YBC-EDS), the Eating Attitudes Test (EAT), and the Penn State Worry Questionnaire (PSWQ). Results: Confirmatory factor analyses of a two-factor second-order model showed adequate values of goodness-of fit indices for non-clinical (normed ÷2=13.4578; df=18; NFI=0.980; GFI=1.00; RMSEA= 0.00) and clinical samples (normed ÷2 = 26.5913; df =18; NFI = 0.944; GFI = 0.981; RMS…
Differential effects of high-dose amisulpride versus flupentixol on latent dimensions of depressive and negative symptomatology in acute schizophreni…
2002
While many acutely ill schizophrenic patients suffer from depressive symptoms, most studies on the efficacy of antipsychotic drugs focus on positive and negative symptoms. Dimensional models of schizophrenic symptoms, based on confirmatory factor analysis (CFA) using structural equation modelling, offer a methodological alternative to compare antipsychotics on empirically justified latent factors. The present report is a refined analysis of a published double-blind study on the D 2 /D 3 -selective antagonist amisulpride (ASP) versus the mixed D 1-5 /5-HT 2 antagonist flupentixol (FPX). CFA was applied to Brief Psychiatric Rating Scale, Scale for the Assessment of Negative Symptoms, Bech-Raf…
German validation of the conners adult ADHD rating scale-self-report: confirmation of factor structure in a large sample of participants with ADHD.
2013
Objective: The Conners Adult ADHD Rating Scales (CAARS) assess symptoms specific to adults that are frequently used and have been translated into German. The current study tests the factor structure of the CAARS in a large sample of German adults with ADHD and compares the means of the CAARS subscales with those of healthy German participants. Method: CAARS were completed by 466 participants with ADHD and 851 healthy control participants. Confirmatory factor analysis was used to establish model fit with the American original. Comparisons between participants with ADHD and healthy controls and influences of gender, age, and degree of education were analyzed. Results: Confirmatory factor anal…
Assessing decentering: validation, psychometric properties, and clinical usefulness of the Experiences Questionnaire in a Spanish sample.
2014
Decentering is defined as the ability to observe one’s thoughts and feelings in a detached manner. The Experiences Questionnaire (EQ) is a self-report instrument that originally assessed decentering and rumination. The purpose of this study was to evaluate the psychometric properties of the Spanish version of EQ-Decentering and to explore its clinical usefulness. The 11-item EQ-Decentering subscale was translated into Spanish and psychometric properties were examined in a sample of 921 adult individuals, 231 with psychiatric disorders and 690 without. The subsample of nonpsychiatric participants was also split according to their previous meditative experience (meditative participants, n = 3…
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…
Translation and Testing of the Italian Version of FAMCARE-2: Measuring Family Caregivers' Satisfaction With Palliative Care.
2017
Family satisfaction is an important outcome of palliative care and is a critical measure for health care professionals to address when assessing quality of care. The FAMCARE-2 is a widely used measure of family satisfaction with the health care received by both patient and family in palliative care. In this study, a team of Italian researchers culturally adapted the FAMCARE-2 to the Italian language and psychometrically tested the instrument by measuring satisfaction of 185 family caregivers of patients admitted into two palliative care services. FAMCARE-2 showed excellent levels of internal consistency (Cronbach’s α coefficient = .96) and test–retest reliability ( r = .98, p < .01). Th…
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…
French validation of the Stroke Specific Quality of Life Scale (SS-QoL).
2018
To adapt the SS-QoL into French and test its psychometric properties.Seventy-seven patients from a population-based registry were enrolled 3 months after their stroke. SS-QoL, NIHSS score, Barthel index, HAD, FSS, SF-36 scales, and MMSE were administered at enrolment. SS-QoL was re-administered at 15 days and 2 months. Internal consistency was assessed by Cronbach's α coefficients, factorial validity by an exploratory factor analysis and external validity by Mann-Whitney test and Spearman's correlations (ρ), comparing SS-QoL scores with those obtained from established scales. Reliability was assessed by intra-class correlation coefficients (ICC) and responsiveness by standardized effect siz…
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…
