Background and Purpose: Studies investigating psychological interventions for the promotion of well-being in people with amyotrophic lateral sclerosis (ALS) are lacking. The purpose of the current study was to examine the use of an ALS-specific mindfulness-based intervention for improving quality of life in this population., Methods: A randomized, open-label and controlled clinical trial was conducted on the efficacy of an ALS-specific meditation programme in promoting quality of life. Adults who received a diagnosis of ALS within 18 months were randomly assigned either to usual care or to an 8-week meditation training based on the original mindfulness-based stress reduction programme and tailored for people with ALS. Quality of life, assessed with the ALS-Specific Quality of Life Revised scale, represented the primary outcome, whilst secondary outcomes included anxiety and depression, assessed with the Hospital Anxiety and Depression Scale, and specific quality of life domains. Participants were assessed at recruitment and after 2, 6 and 12 months. The efficacy of the treatment was assessed on an intention-to-treat basis of a linear mixed model., Results: A hundred participants were recruited between November 2012 and December 2014. Over time, there was a significant difference between the two groups in terms of quality of life (β = 0.24, P = 0.015, d = 0.89). Significant differences between groups over time were also found for anxiety, depression, negative emotions, and interaction with people and the environment., Conclusions: An ALS-specific meditation programme is beneficial for the quality of life and psychological well-being of people with ALS., (© 2017 EAN.)

Background: The concurrent comparison of questionnaires assessing health-related quality of life in the same population is necessary for better appreciating their performance and to select the best instrument for a given purpose (e.g. clinical trials and observational studies)., Aim: The aim of this study was to compare the measurement properties of two disease-specific and generic questionnaires: the Obesity-related Well-Being (ORWELL97), the Obesity-Related Disability test (TSD-OC), the EuroQoL, and the World Health Organization Quality of Life questionnaire., Materials/subjects: Two-hundreds and forty-nine obese inpatients [age 47 (standard deviation, SD 15) years, body mass index 44.4 (SD 5.2) kg/m(2), 69 % female] completed the four questionnaires before and after a 3-week multidisciplinary weight reduction program. Standard measurement properties were calculated and compared., Results: Intra-class correlation coefficient ranged from 0.73 to 0.90 for most of the instruments and subscales. The standard error of measurement ranged from 9 to 21 % for the generic instruments, and from 9 to 44 % for the specific questionnaires. Missing data and ceiling effects were found for TSD-OC. Responsiveness was similar for all the instruments. The correlations between the change scores of the instruments were small (<0.37)., Conclusions: It was not possible to identify a "best" instrument, but overall the ORWELL97 seems to show better measurement properties. The two specific instruments measured different constructs and they did not show a clear superior performance compared to the generic questionnaires.
