Summary

In this pilot study, the investigators will determine the feasibility and acceptability of multiple low-cost behavioral interventions, designed with end-user input, to promote HIV retesting among adults in rural Kenya and Uganda who have higher risk of HIV exposure.

Detailed description

HIV re-testing is crucial in ensuring early identification of disease to promote well-being of an individual as well as preventing onward spread of infection by treating those identified to have disease promptly. The proposed study aims to identify approaches that would encourage individuals aged 15 years and above at high risk of HIV infection to retest. This IBIS Megastudy pilot trial will pilot 11 intervention prototypes for acceptability, feedback, and implementation outcomes prior to using the interventions in a larger-scale Megastudy trial (main trial to be submitted as a separate CT.gov record).

Interventions

Type	Name	Description
BEHAVIORAL	Risk assessment messaging	Participants who are randomized to the "HIV risk assessment" arm will receive a brief video message at their baseline visit, containing information related to HIV risk assessment core concepts and encouraging them to return for a repeat HIV test. They will also receive brief SMS follow-up messages at 8 and 11 week after baseline reminding them about HIV retesting and re-emphasizing concepts from the HIV risk assessment content category.
BEHAVIORAL	U=U messaging	Participants who are randomized to the "U=U" arm will receive a brief video message at their baseline visit, containing information related to U=U core concepts and encouraging them to return for a repeat HIV test. They will also receive brief SMS follow-up messages at 8 and 11 week after baseline reminding them about HIV retesting and re-emphasizing concepts from the U=U content category.
BEHAVIORAL	Healthy Living messaging	Participants who are randomized to the "Healthy Living" arm will receive a brief video message at their baseline visit, containing information related to Healthy Living core concepts and encouraging them to return for a repeat HIV test. They will also receive brief SMS follow-up messages at 8 and 11 week after baseline reminding them about HIV retesting and re-emphasizing concepts from the Healthy Living content category.
BEHAVIORAL	Community benefits messaging	Participants who are randomized to the "Community benefits" arm will receive a brief video message at their baseline visit, containing information related to Community Benefits core concepts and encouraging them to return for a repeat HIV test. They will also receive brief SMS follow-up messages at 8 and 11 week after baseline reminding them about HIV retesting and re-emphasizing concepts from the Community Benefits content category.
BEHAVIORAL	Fresh start effect	Participants who are randomized to the "Fresh start effect" arm will receive a brief video message at their baseline visit, containing information related to Fresh Start core concepts and encouraging them to return for a repeat HIV test. They will also receive brief SMS follow-up messages at 8 and 11 week after baseline reminding them about HIV retesting and re-emphasizing concepts from the Fresh start effect content category.
BEHAVIORAL	Education-based messaging (#1)	Participants who are randomized to the "Education-based #1" arm will receive a brief video message at their baseline visit, containing information related to HIV education core concepts and encouraging them to return for a repeat HIV test. They will also receive brief SMS follow-up messages at 8 and 11 week after baseline reminding them about HIV retesting and re-emphasizing concepts from the Education-based #1 content category.
BEHAVIORAL	Education-based #2 messaging (gamification)	Participants who are randomized to the "Education-based #2" arm will receive a brief video message at their baseline visit, containing information related to HIV education/gamification core concepts and encouraging them to return for a repeat HIV test. They will also receive brief SMS follow-up messages at 8 and 11 week after baseline reminding them about HIV retesting and re-emphasizing concepts from the Education-based/gamification content category.
BEHAVIORAL	Default appointment messaging	Participants who are randomized to the "Default appointment" arm will receive a brief video message at their baseline visit, containing information related to Default Appointment core concepts and encouraging them to return for a repeat HIV test. They will also receive brief SMS follow-up messages at 8 and 11 week after baseline reminding them about HIV retesting and re-emphasizing concepts from the Default Appointment content category.
BEHAVIORAL	Reserved for you messaging	Participants who are randomized to the "Reserved for you" arm will receive a brief video message at their baseline visit, containing information related to the Reserved for you core concepts and encouraging them to return for a repeat HIV test. They will also receive brief SMS follow-up messages at 8 and 11 week after baseline reminding them about HIV retesting and re-emphasizing concepts from the Reserved for you content category.
BEHAVIORAL	Social norms messaging	Participants who are randomized to the "Social norms" arm will receive a brief video message at their baseline visit, containing information related to Social Norms core concepts and encouraging them to return for a repeat HIV test. They will also receive brief SMS follow-up messages at 8 and 11 week after baseline reminding them about HIV retesting and re-emphasizing concepts from the Social Norms content category.
BEHAVIORAL	Empowerment messaging	Participants who are randomized to the "Empowerment/goal setting" arm will receive a brief video message at their baseline visit, containing information related to Empowerment core concepts and encouraging them to return for a repeat HIV test. They will also receive brief SMS follow-up messages at 8 and 11 week after baseline reminding them about HIV retesting and re-emphasizing concepts from the Empowerment content category.
