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…
Validation of the German Version of the Quality of Dying and Death Questionnaire for Informal Caregivers (QODD-D-Ang).
2015
Abstract Context The quality of dying and death (QOD) influences end-of-life care for patients and their relatives. To the best of our knowledge, there are currently no validated standard instruments for evaluating the QOD of patients in palliative care units (PCUs) in Germany. Objectives This study aimed to validate the German version of the multidimensional questionnaire "Quality of Dying and Death" for informal caregivers (QODD-Deutsch-Angehorige [QODD-D-Ang]) and provide a detailed report on its validity and reliability. Methods The QODD was forward/backward translated following the European Organization for Research and Treatment of Cancer guidelines. Data collected in two German palli…
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…
Monitoring cognitive changes: Psychometric properties of six cognitive tests
2004
Objectives. Repeated neuropsychological assessments are often used to monitor change in cognitive functioning over time. Thus, knowledge about the reliability and stability of neuropsychological tests and the effects of age and IQ is of paramount importance. In this study we document, for six cognitive tests: test-retest reliabilities, practice effects, reliable change (RC) indices corrected for practice, and the impact of premorbid IQ and age. Design. A sample of 188 normal adults (aged 40-70 years) were administered, on two occasions, one or more of the following tests: the Graded Naming Test (GNT), the Silhouettes Test, two tests of verbal fluency, the Modified Wisconsin Card Sorting Tes…
Quality of Life in Individuals Affected by Arnold Chiari Malformation: Comparison and Validation of a Measurement Instrument.
2017
BACKGROUND Introduction. Arnold Chiari Malformation (ACM) type I is a pathology whose symptomatology has repercussions for the quality of life of those affected by it. Quality-of-life measurement instruments can allow the severity of the impact of Chiari type I malformation on patients' lives to be monitored. The Chiari Symptom Profile (CSP) is a valid and reliable instrument designed for this purpose. The aim of the study was to adapt the CSP to Spanish and to explore the reliability and validity of this construct in the context of Spanish-speaking patients with ACM. METHODS The English CSP instrument has a good internal validity and consistency. We used a standardized procedure for the li…
Internal and external validity of the WHO Well-Being Scale in the elderly general population
1999
The objectives of this study were (i) to evaluate the validity of the WHO Well-Being Scale in elderly subjects and (ii) to assess the influence of demographic variables on subjective quality of life. A sample of 254 elderly subjects completed the 22-item WHO Well-Being Scale. The scale had an adequate internal and external validity. However, the short 10-item and 5-item versions were equally valid. Low scores indicating decreased well-being were related to the presence of a psychiatric disorder or, independently, to poor living conditions. The Well-Being Scale and their short versions would appear to be useful instruments for identifying subjects with reduced subjective quality of life.
Diagnosing ICD-10 depressive episodes: superior criterion validity of the Patient Health Questionnaire.
2004
<i>Background:</i> Diagnosing and monitoring depression in primary care remains an issue of significant public health concern. Clinicians and researchers need to know if any one screening instrument is superior to the others in diagnosing ICD-10 depressive episodes. This study aimed to examine the criterion validity for diagnosing ICD-10 depressive episodes of the Patient Health Questionnaire (PHQ) in comparison with 2 well-established instruments, the Hospital Anxiety and Depression Scale (HADS), and the WHO Well-Being Index 5 (WBI-5). <i>Methods:</i> Five hundred and one medical outpatients completed the questionnaires and had a clinical interview. The presence of …
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…
