Evaluating Relapse Knowledge in People with Multiple Sclerosis: A Cross-Sectional Study on the Development and Validation of the Relapse Knowledge Questionnaire.

BACKGROUND: Multiple sclerosis (MS) knowledge is a prerequisite for active patient engagement in medical decision-making. Treatment of relapses in MS is a clinical field with many uncertainties and each acute relapse requires decisions regarding possible options for action, indicating the need for patient involvement. However, there is no validated instrument assessing relapse knowledge in people with MS. Our study aims to develop a valid MS relapse questionnaire for use as an outcome instrument for educational interventions. METHODS: A multidisciplinary panel developed the relapse knowledge questionnaire (RKQ) based on a previously developed questionnaire. We tested the RKQ on MS patients for comprehensibility, usability and acceptance in qualitative think-aloud interviews and conducted a cross-sectional quantitative online survey to validate the questionnaire. People with suspected or confirmed relapsing-remitting MS and a recent relapse experience were eligible for inclusion. We checked normal distribution of the RKQ score and determined the item difficulty. Construct validity was analysed using correlational analysis. RESULTS: The final RKQ consists of 10 items. After minor changes of the RKQ during pre-testing (n = 2), pilot testing (n = 10) confirmed the usability and acceptance of the instrument. The subsequent validation study (n = 203) resulted in a mean item difficulty of 0.44, ranging from 0.18 to 0.83. Seven items were particularly difficult and answered incorrectly by more than 50 % of participants. Construct validity of the RKQ was satisfactory. The RKQ score correlated only weakly with participants' degree of education (|rp|>0.1), years since diagnosis (|rp|>0.1), and the intention to receive corticosteroids (|rp|>0.1). CONCLUSION: This study indicates the validity of the RKQ and proposes that the RKQ is a suitable instrument to assess relapse knowledge in people with MS participating in educational interventions.

The Psychosocial Impact of Parental Multiple Sclerosis on Children and Adolescents: A Systematic Review.

BACKGROUND: Multiple sclerosis (MS) is a common debilitating neurologic disease that affects mostly young women. This review provides an overview of research on the psychosocial impact of parental MS on children to inform clinicians and support people with MS considering parenthood. METHODS: A systematic review of the literature was performed by searching the MEDLINE, PsycINFO, and PSYNDEX databases. We included quantitative and mixed-method studies assessing psychosocial outcomes of children with a parent with MS. Studies were screened for eligibility and evaluated for risk of bias. RESULTS: We screened 608 references, assessed 72 studies in full-text, and included 28 studies in this review. Most of the studies reported on psychosocial adjustment processes, with most results suggesting negative consequences, including difficulties with mood, behavior, or social interaction. Several studies also described associations between children with a parent with MS and increased incidences of psychiatric disorders. Nevertheless, some studies claimed that children with a parent with MS were not more likely to have psychosocial problems compared with children without a parent with MS. A few studies indicated probable positive effects of parental MS, eg potentially increased social competence. Other investigated outcomes were children's coping skills, early childhood development, body image, and effects on education, and these were unaffected or only slightly affected by having a parent with MS. CONCLUSIONS: Having a parent with MS has a relevant effect on children. However, the heterogeneous nature and varying quality of the included studies limit the interpretability of these findings. Further research is needed to provide robust evidence.
