In November 2021, clients attending the Melbourne Sexual Health Centre were invited to participate in the Annual Client Satisfaction Survey by receiving an SMS link at 5:15pm on the day they attended the clinic. We analysed the response time data and found that most (60%; 168/278) individuals responded to the survey during the time period 5:00-5:59pm, which wasaround the time when they received the SMS. We concluded that individuals responded quickly to the survey via an SMS link.
