: The aim of this study was to develop and validate the (SMS).: Forty-one items were generated through a literature review. Items were submitted to a preliminary psychometric validation process consisting of principal component analysis, internal consistency, test-retest reliability, and floor and ceiling effects using data from 164 participants. Criterion validity was assessed by comparing the SMS with the 12-item Short Form Health Survey (SF-12). Participants were recruited internationally through online channels and questionnaires were completed online.: The SMS contains 16 items describing three components: speech and voice, language, and swallowing. Internal consistency (Cronbach's alpha) of the three components was satisfactory ( = 0.89- = 0.91). Criterion validity was evaluated using Spearman's rank correlation coefficient (). A statistically significant weak to moderate correlation between the SMS and the SF-12 was identified ( = -0.004- = -0.359). No floor or ceiling effects were present. The SMS demonstrated strong test-retest reliability. All items had an intra-class correlation coefficient ≥0.70.: The SMS is a psychometrically robust patient-reported outcome measure to assess speech-language pathology symptoms in persons with MS.
本研究的目的是开发并验证具体名称未给出。通过文献综述生成了41个条目。使用来自164名参与者的数据，将这些条目提交至一个初步的心理测量学验证过程，该过程包括主成分分析、内部一致性、重测信度以及地板效应和天花板效应。通过将SMS与12项简短健康调查问卷(SF - 12)进行比较来评估效标效度。通过在线渠道在国际范围内招募参与者，并在线完成问卷。SMS包含16个描述三个组成部分的条目：言语和嗓音、语言以及吞咽。三个组成部分的内部一致性（克朗巴哈系数）令人满意（= 0.89 - = 0.91）。使用斯皮尔曼等级相关系数()评估效标效度。在SMS与SF - 12之间发现了具有统计学意义的弱至中度相关性（= -0.004 - = -0.359）。不存在地板效应或天花板效应。SMS表现出很强的重测信度。所有条目的组内相关系数≥0.70。SMS是一种心理测量学上稳健的患者报告结局指标，用于评估多发性硬化症患者的言语语言病理学症状。
