Is the Concept of Quality of Life Relevant for Multiple Sclerosis Patients with Cognitive Impairment? Preliminary Results of a Cross-Sectional Study

Background: Cognitive impairment occurs in about 50 % of multiple sclerosis (MS) patients, and the use of self-reported outcomes for evaluating treatment and managing care among subjects with cognitive dysfunction has been questioned. The aim of this study was to provide new evidence about the suitability of self-reported outcomes for use in this specific population by exploring the internal structure, reliability and external validity of a specific quality of life (QoL) instrument, the Multiple Sclerosis International Quality of Life questionnaire (MusiQoL). Methods: Design: cross-sectional study. Inclusion criteria: MS patients of any disease subtype. Data collection: sociodemographic (age, gender, marital status, education level, and occupational activity) and clinical data (MS subtype, Expanded Disability Status Scale, disease duration); QoL (MusiQoL and SF36); and neuropsychological performance (Stroop color-word test). Statistical analysis: confirmatory factor analysis, item-dimension correlations, Cronbach’s alpha coefficients, Rasch statistics, relationships between MusiQoL dimensions and other parameters. Principal Findings: One hundred and twenty-four consecutive patients were enrolled. QoL scores did not differ between the 69 cognitively non-impaired patients and the 55 cognitively impaired patients, except for the symptoms dimension. The confirmatory factor analysis performed among the impaired subjects showed that the structure of the questionnaire matched with the initial structure of the MusiQoL. The unidimensionality of the MusiQoL dimensions was preserved, and th

0035-3787 (Electronic) 0035-3787 (Linking) Journal articleINTRODUCTION: Health-related quality of life (HRQL) measurements have become an important outcome both for population health assessment and for evaluating treatments and care management. HRQL indicators require completion of a well-validated questionnaire. Few specific questionnaires are available for French multiple sclerosis (MS) patients. The Multiple Sclerosis International Quality of Life questionnaire (MusiQoL), a self-administered and multidimensional questionnaire, was co-developed and validated in 17 countries, including France. We report the main results of the French clinical validity of this instrument. METHODS: The French patients were recruited between January 2004 and February 2005. The main inclusion criteria were: diagnosis of MS according to McDonald criteria, age over 18 years, having given informed consent. The self-administered survey materials that were completed by the patients included the MusiQoL, the generic HRQL questionnaire SF36, and one checklist of 14 MS-specific symptoms reported by the patients. MusiQoL comprises 31 items describing nine dimensions: activity of daily living (eight items), psychological well-being (four), symptoms (three), friends relationships (four), family relationships (three), satisfaction with health care (three), sentimental and sexual life (two), coping (two), and rejection (two). A global index score is computed. Patients were evaluated at inclusion (T0), and retested 21+/-7 days later (T1). At T0, an experienced neurologist collected sociodemographic data, clinical history related or unrelated to the MS condition, treatments. At T1, change in the patient's health status from T0 was reported. RESULTS: The analyses were performed with data from 179 subjects. The mean patient age was 44.1 years (SD: 11.5); there were 120 women and 59 men, 58.1% were unemployed, 13.6% had a tertiary educational level. MS clinical forms were 69 relapsing-remitting, 47 secondary-progressive, 37 primary-progressive, and nine clinically isolated syndrome. The EDSS median was 4.5 (25-75(th) percentiles: 2.5-6.0). The final French version showed satisfactory psychometric properties (external validity, internal consistency, reliability, reproducibility, and acceptability). CONCLUSION: The availability of a reliable and valid French version of MusiQoL, a self-administered and multidimensional questionnaire, co-developed in different countries, enables evaluation of QoL in French MS patients that are eligible for international multicenter studies

Assessment of psychiatric inpatient satisfaction: A systematic review of self-reported instruments.

International audienceBACKGROUND: There is a growing concern about satisfaction with inpatient psychiatric services. There are currently numerous satisfaction instruments available to psychiatric inpatients, but little guidance on which among them to select. AIMS: To provide an overview of the psychometric properties and the content of satisfaction instruments available to psychiatric inpatients. METHODS: Systematic searches of Medline database to identify inpatient satisfaction questionnaires. Assessment of the instruments according to relevant psychometric properties. RESULTS: Fifteen satisfaction instruments were identified. The target population differed according to the instrument. Methods used to generate items were heterogeneous. These instruments were based on a mixed approach including patients' points of view, expert opinions, and literature reviews, causing the content of questionnaires to vary. Reliability and validity were not systematically tested. CONCLUSION: The validation of a common inpatient satisfaction instrument is a major challenge. Recommendations for the future development of satisfaction instruments may include: item generation based exclusively on the patient's point of view; a validation process on a large and representative population; and an instrument combining generic (core questionnaire) and specific (additional modules) approaches
