What was measured
The SID satisfaction questionnaire was administered twice during the study and asked participants to respond to five statements using a Likert scale from "Strongly Disagree" to "Strongly Agree". Questionnaire items were as follows: "I felt comfortable injecting the study drug by myself" (Comfortable), "The SID was convenient and easy to use" (Easy to Use), "I am confident giving myself an injection in the thigh with the SID" (Confident), "Taking all things into account I find self-administration using the SID satisfactory" (Satisfactory), "If given the opportunity I would choose to continue self-injecting the study drug using the SID in the future" (Continue). Participants could only select one response per questionnaire item. There was no calculation of any score, but rather, descriptive summaries were generated by item response. The percentage of participants was reported by the response given for each item on the SID satisfaction questionnaire.
Analysis population: Safety Population. Only participants who performed self-administration were included. The number of participants who responded to the questionnaire item at each assessment (n) is shown in the table.
