Introduction/Objective Patient-reported outcomes have been recognized as an important way of assessing health and well-being of patients with multiple sclerosis (MS). The aim of the study is to determine the correlation between different subscales of Patient-Reported Impact of Spasticity Measure (PRISM) and Multiple Sclerosis Spasticity Scale (MSSS-88) scales in the estimation of spasticity influence on different domains Methods The study is a cross-sectional observational study. MSSS-88 and PRISM scales were analyzed in five domains (body-function domain, activity domain, participation domain, personal factors/wellbeing domain, and hypothesis). For statistical interpretation of the correlation we performed the Spearman’s ρ-test, concurrent validity, divergent validity, and the linear regression model. Results We found a significant correlation between subscales of evaluated MSSS-88 and PRISM scales for body domains; the highest correlation was between the need for assistance/positioning (NA/P) and walking (W). Spasticity has the weakest correlation with the need for intervention (NI). The presence of pain has a negative impact and significant positive correlation between pain discomfort and NI. In the domain of body function for males, there was a non-significant correlation between muscle spasms and NI. The same applies for social functioning and social embarrassment domains, as well as for emotional health and psychological agitation for personal factors/wellbeing domain. The differences between genders of MS patients persist in different domains; muscle spasms are strong predictors for NI, and body movement is a strong predictor versus W for NA/P. Conclusion MSSS-88 and PRISM scales can be considered reliable in measuring different domains of disability for MS patients with spasticity. Because it is shorter, quicker, and simple to use, it is concluded that the PRISM scale can successfully compete with and replace the MSSS-88 scale in certain domains. © 2017, Serbia Medical Society.

The Patient-Reported Impact of Spasticity Measure (PRISM) has been developed recently to assess the impact of spasticity on quality of life after spinal cord injury. Although PRISM may also be useful in patients with multiple sclerosis (MS), its psychometric properties in MS have not been established and PRISM is currently available only in English. The aims of this cross-sectional study were to translate PRISM into the Serbian language (PRISM SR) and examine its validity (construct, convergent, divergent) and reliability (internal consistency, test-retest reliability) in 48 patients with spasticity because of MS diagnosed at least 1 year earlier and in remission at least 3 months. PRISM SR was administered twice 3 days apart. The validity of seven PRISM SR subscales was examined against the Modified Ashworth Scale (MAS), the Numerical Rating Scale (NRS) for spasticity, sex, and education. Internal consistency was assessed with Cronbach α and test-retest reliability with intraclass correlation coefficient for agreement (ICC 2,1). During the forward-backward translation, only one PRISM item required minor cultural adaption. Almost all PRISM SR scores correlated significantly with MAS and NRS scores (r=0.29-0.51, 0.001≤P≤0.043). They were all significantly higher for MAS≥2 group versus the MAS<2 group (0.003≤P≤0.035) and for the NRS≥7 group versus the NRS<7 group (0.001≤P≤0.042), except for the Social Embarrassment subscale (P=0.083). The PRISM SR scores were not significantly different between sexes (P≥0.104) or those with high school versus college degree (P≥0.139). Both Cronbach α (0.78-0.93) and test-retest ICC 2,1 (0.82-0.90) were high. The original PRISM may be translated successfully into other languages. PRISM SR shows adequate validity and reliability for assessing the impact of spasticity on quality of life in patients with MS. © 2015 Wolters Kluwer Health, Inc.
