Control
NO INTERVENTIONNo change will be made to the introduction content or the consent mode (active opt-in and active opt-out) from other related trials
Modified Intro, Standard Consent
EXPERIMENTALModified introductory language will be used, but the consent structure (active opt-in and active opt-out) will remain the same.
Modified Intro, Active Opt-in
EXPERIMENTALModified introductory language will be used, and the consent mode will be changed to active opt-in only.
Modified Intro, Active Opt-out
EXPERIMENTALModified introductory language will be used, and the consent mode will be changed to active opt-out only.
Modified Intro, Passive Opt-in
EXPERIMENTALModified introductory language will be used, and the consent mode will be changed to passive opt-in only.
Interventions
A variation in the introductory content to motivate participants to complete the survey. Participants will be presented with modified introductory language based on the findings from local focus groups and key informant interviews.
A variation in the consent mode to motivate participants to complete the survey. Participants will be given the choice to actively opt-in to the survey, if they do not respond, the survey will terminate.
A variation in the consent mode to motivate participants to complete the survey. Participants will be given the choice to actively opt-out to the survey, if they do not respond, the survey will continue.
A variation in the consent mode to motivate participants to complete the survey. Participants will be given the choice to passively opt-in to the survey, if they do not hang-up, the survey will continue.
