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…
Development and validation of the mastocytosis quality of life questionnaire: MC-QoL
2016
Background Mastocytosis is a heterogeneous disease characterized by a clonal expansion of mast cells in various organs. The vast majority of patients affected suffer from signs and symptoms caused by mediator release from mast cells. Although the disease burden is high, there is currently no specific instrument to measure health-related quality of life (HRQoL) impairment in patients with mastocytosis. Objective The aim of this study was to develop and validate a disease-specific tool to assess HRQoL impairment in patients with cutaneous and indolent systemic mastocytosis, the Mastocytosis Quality of Life Questionnaire (MC-QoL). Methods Sixty-two potential MC-QoL items were developed in a co…
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…
Relationships between psychomotor retardation and EEG power spectrum in major depression.
1992
In 63 depressed patients, the associations between severity of depression, psychomotor retardation, assessed by the Bech-Rafaelsen Melancholia Scale, and EEG spectral analysis were examined. Slow EEG activity (theta 2/alpha 1 bands) was positively and fast activity (alpha 3/beta bands) negatively correlated with the observed retardation. Out of the four retardation subitems (motor, verbal, intellectual and emotional), motor retardation was closest correlated with slow EEG activity.
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 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…
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…
