Add a Keyword to Initiate a Text Message Survey
FollowWith Mosio, a text message survey can be initiated by sending a specific keyword to a designated phone number (STUDY, for example, not case sensitive), triggering the survey to begin. This keyword and number can be advertised to participants, allowing them to easily opt-in and start the survey via text.
In the survey you are editing, under Keywords, click "Show" and then Add Keyword.
Any keywords you enter there, when texted (that word only, no others) to the texting number for that project, the participant will start the text message survey you've created.
All survey functions (Question Actions, Unresponsive Participant Actions aka "nudges") work.
Single Message Response
The most common use case is to setup a specific reply message. To do this, setup a 1 question survey, with the Type set to Terminating Question. When the participant texts in the keyword, the survey will start, send the first question, and end.
Adding to a Storyline
If you want to setup an enrollment keyword, you can add a Question Action to the first question. The action should be "Storyline Add", then select your storyline, and use "today" as the start date. Other options for start date are "yesterday", "tomorrow", "next Sunday", etc.
