OBJECTIVES : The Treatment Satisfaction Questionnaire for Medication (TSQM) is a valid and reliable measure that is becoming a reference for measuring treatment satisfaction. The primary objectives of this study were to 1) validate the electronic version of the TSQM; 2) provide evidence for online methods of electronic migration of Patient-Reported Outcomes. METHODS : Patients using Tecfidera or Gilenya completed the TSQM electronically. Descriptive statistics were used to characterize the participants. Floor and ceiling effects were calculated per item. To evaluate the scaling properties and construct validity of the eTSQM, Classic Test Theory and Rasch measurement theory (RMT) was used. SAS 9.4 and RUMM2030 were used to complete the statistical analyses. Patients were also cognitively debriefed on the eTSQM both in person and online. RESULTS :
