The Cholera‐Hospital‐Based‐Intervention‐for‐7‐days (CHoBI7) mobile health (mHealth) program delivers mobile messages to diarrhea patient households promoting water treatment and handwashing with soap. The randomized controlled trial (RCT) of the CHoBI7 mHealth program demonstrated this intervention was effective in significantly reducing diarrhea and stunting in young children. The objective of this study was to assess the implementation of the CHoBI7 mHealth program in delivering mHealth messages during this RCT.
A total of 517 diarrhea patient households received weekly text, voice, and interactive voice response (IVR) messages from the CHoBI7 mHealth program over the 12‐month program period. The program process evaluation indicators were the following: the percentage of CHoBI7 mHealth messages received (program fidelity and dose) and fully listened to by program households (program fidelity and dose), and beneficiaries reporting receiving and sharing a mHealth message from the program (program reach) in the past two weeks.
92% of text messages were received by program households. 83% of voice and 86% of IVR messages sent were fully listened to by at least one household member. 81% of IVR quiz responses from households were answered correctly. Program households reported receiving a CHoBI7 mHealth message in the past two weeks at 79% of monthly household visits during the 12‐month program. 77% of participants reported sharing a program message with a spouse, 55% with a neighbor, and 49% with a child during the program period.
There was high fidelity, dose, and reach of messages delivered for the CHoBI7 mHealth program. This study presents an approach for process evaluation that can be implemented to evaluate future mHealth programs.
