| Study name |
The effectiveness of a text message reminder which participants can respond to, compared with a ‘no reply’ text message on questionnaire response rates |
| Methods |
To evaluate the effectiveness on completion of follow‐up postal questionnaires of sending a two‐way text message reminder compared with a standard one‐way text message with no option to reply. |
| Data |
|
| Comparisons |
Intervention 1: “Two way” text messages sent at the same time as host trial participants are expected to receive their postal follow‐up questionnaire. The text message will encourage them to text back if they have any queries. Intervention 2: “One way” text message sent at the same time as host trial participants are expected to receive their postal follow‐up questionnaire. Participants will not be able to reply to this message. |
| Outcomes |
Primary: proportion of questionnaires completed at the 3‐month follow‐up. Secondary: ~ Time to questionnaire return (number of days between the questionnaire being mailed to participants and it being recorded as returned). ~ Proportion of patients requiring at least one return reminder notice (a letter at 2 and 4 weeks and a telephone call at 6 weeks if the questionnaire is not returned). ~ If possible, qualitative methods will be used to interrogate the text message responses sent by participants to explore topics and reasons for contacting the trial team. ~ If possible, a descriptive exploration will be done of whether text message topics sent by participants were associated with response rates to questionnaires. |
