Brief Summary:
This study evaluates the effect of two different airtime incentive timings on interactive voice response (IVR) survey cooperation, response, refusal and contact rates, as compared to a control group, in Bangladesh and Uganda.

Condition or disease Intervention/treatment Phase
Surveys and Questionnaires Noncommunicable Diseases Other: Pre-survey incentive Other: Post-survey incentive Not Applicable

Detailed Description:
Using random digit dialing sampling techniques, the study randomized RDD participants to one of three airtime incentive timings, some of all of that incentive being contingent on their completing the noncommunicable disease risk factor survey. This mobile phone survey was sent as an interactive voice response (IVR). In IVR surveys, participants use their touch tone key pad to answer pre-recorded questions. (i.e. If you are male, press 1; if you are female, press 2). This study was conducted in both Bangladesh and Uganda.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 2287 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Participants were randomized to one of three airtime incentive timings: 1) no incentive; 2) 0.1X incentive received before the IVR noncommunicable disease risk factor survey is sent, followed by 1X incentive upon completing the survey; or 3) 1X incentive received upon completing the survey.
Masking: Single (Outcomes Assessor)
Primary Purpose: Other
Official Title: A Randomized Controlled Trial of Varying Airtime Incentive Timing to Improve Interactive Voice Response (IVR) Survey Performance in Bangladesh and Uganda
Actual Study Start Date : March 26, 2017
Actual Primary Completion Date : November 1, 2017
Actual Study Completion Date : November 1, 2017

Arm Intervention/treatment
No Intervention: Control
No Airtime Incentive was given for completing the survey
Experimental: Pre-survey incentive
0.1X incentive before the survey, 1X afterwards
Other: Pre-survey incentive
An incentive of is given in the form of airtime to motivate participants to complete the survey. Participants were sent 0.1X before the were sent a mobile phone survey and an additional 1X after completing the survey.

Experimental: Post-survey incentive
1X incentive after the survey
Other: Post-survey incentive
An incentive in the form of airtime to motivate participants to complete the survey. Participants were given Bangladeshi Taka or Ugandan Shillings worth of certain airtime for completing the survey.




Primary Outcome Measures :
  1. Cooperation Rate #1 [ Time Frame: Through study completion, an average of one month ]
    As defined by American Association for Public Opinion Research, cooperation rate is defined as I/(I+P+R) where I is complete interviews, P is partial interviews, and R is refusals and breakoffs.

  2. Response Rate #4 [ Time Frame: Through study completion, an average of one month ]
    As defined by American Association for Public Opinion Research, response rate is defined as (I+P)/(I+P+R+eU) where I is complete interviews, P is partial interviews, R is refusals and breakoffs, and eU is the estimated eligible proportion of unknowns


Secondary Outcome Measures :
  1. Refusal Rate #2 [ Time Frame: Through study completion, an average of one month ]
    As defined by American Association for Public Opinion Research, refusal rate is defined as (R)/(I+P+R+eU) where R is refusals and breakoffs, I is complete interviews, P is partial interviews, and eU is the estimated eligible proportion of unknowns

  2. Contact Rate #2 [ Time Frame: Through study completion, an average of one month ]
    As defined by American Association for Public Opinion Research, contact rate is defined as (I+P+R)/(I+P+R+eU) where I is complete interviews, P is partial interviews, R is refusals and breakoffs, and eU is the estimated eligible proportion of unknowns
