Background: Assessment of disease impact in multiple sclerosis (MS) is usually driven by information obtained directly from patients using patient-reported outcomes. However, when patients' response in longitudinal studies is less reliable or missing, proxy respondents may be used.
Objective: The objective of this paper is to evaluate whether long-term patient scores can be reliably estimated using scores obtained from proxies.
Background: The Multiple Sclerosis Neuropsychological Screening Questionnaire (MSNQ) was developed for screening of MS patients at risk for cognitive impairment with a patient self-report (MSNQ-P) and an informant version (MSNQ-I). The objective of this study was to validate the Dutch versions and determine their interpretability.
Methods: The MSNQ was completed by 121 MS patients and their partners (informants).
Background: This study examined whether MS patients and proxy respondents agreed on change in disease impact, which was induced by treatment. This may be of interest in situations when patients suffer from limitations that interfere with reliable self-assessment, such as cognitive impairment.
Methods: MS patients and proxies completed the Multiple Sclerosis Impact Scale (MSIS-29) before and after intravenous steroid treatment.
Background: The use of self-report measurements in clinical settings is increasing. However, in patients with limitations that interfere with reliable self-assessment such as cognitive impairment or mood disturbances, as may be the case in multiple sclerosis (MS), data collection might be problematic. In these situations, information obtained from proxy respondents (e.
