Abstract
BACKGROUND: There is growing recognition that communication and language can be compromised in persons with multiple sclerosis (MS). However, patient-reported outcome measures (PROMs) designed to measure communication and language function in MS are currently lacking. OBJECTIVES: This study aimed to develop and validate a novel PROM, the Communication and Language Assessment questionnaire for persons with Multiple Sclerosis (CLAMS). METHODS: One-hundred and ninety-nine participants were recruited internationally through online channels. Participants completed an online questionnaire consisting of 41-items generated from the: (1) La Trobe Communication Questionnaire (LCQ), (2) Speech pathology-specific questionnaire for persons with Multiple Sclerosis (SMS), and (3) published research describing communication and language in MS. These items were then submitted to preliminary psychometric evaluation, including principal component analysis, internal consistency, test-retest reliability, criterion validity, and analyses of floor and ceiling effects. Criterion validity was assessed by comparing the CLAMS with the Communication Participation Item Bank (CPIB). RESULTS: The final CLAMS contained 11-items. Internal consistency was high (α = 0.944) and test-retest reliability. All items produced an intra-class correlation coefficient ≥ 0.70. No floor or ceiling effects were present. A statistically significant strong correlation between the CLAMS and the CPIB was identified (r = -0.750, p = ≤ 0.001). CONCLUSION: The CLAMS is a reliable and valid PROM that assesses self-perceived communication and language function in MS. This tool can be used for research and clinical purposes to measure intervention outcomes, monitor symptom evolution, evaluate service delivery, facilitate patient-centred care, and as an adjunct to clinical assessment.
