Clinical Trial Summary
In collaboration with Korean Schools of Northern California, the investigators will test if a
community-based intervention delivered by lay health educators (LHEs) increases testing
uptake among Korean Americans. A pilot cluster randomized controlled trial (RCT) with 300
participants from about 12 Korean Schools will be conducted to evaluate the efficacy of the
LHE-led intervention in promoting COVID-19 testing. Participating schools will recruit Korean
Schoolteachers as LHEs. According to the group assignment of schools where participants are
recruited, the LHE group participants will receive 1) LHE outreach/support, 2) COVID-19
at-home antigen test kits, and 3) the instruction to use the kit while the control group
participants will receive test kits and the instruction. Participants will complete an online
survey at baseline, weeks 4, and 8. The primary outcome is the COVID-19 testing receipt. The
secondary outcomes are intention to get tested, perceived accuracy, benefits and risks of
testing, perceived barriers to testing, understanding of negative or positive results, and
family members' testing receipt.
Description:
Lay Health Educators (LHEs) Korean Schools in Northern California will be classified into two
strata by geographic location (urban, suburban/rural). Collaborating with the KSNC, our
research team will recruit about 12 schools (6 urban and 6 suburban/rural). Within each
stratum, schools will be randomly assigned in a 1-to-1 ratio to either the
LHE-plus-instruction condition (LHE condition) or the instruction-only condition (control
condition). Participating schools will recruit two teachers as LHEs (LHE condition only), ii)
announce the proposed study to enrolled students' parents, iii) recruit KAs from the school
and/or community, and iv) distribute at-home antigen test kits to participants. Research
staff will contact potential LHEs to conduct a brief telephone screening to find out their
eligibility. If they meet the eligibility and provide an informed consent form via DocuSign,
they will be invited to attend two training sessions (6 hours, orientation and intervention
delivery) over Zoom. During the training sessions, our research team will provide LHEs
Orientation Training Manual, which contains background information, project objectives,
project description, lay health educator's responsibilities/activities,
compensation/assistance, RCT participant's responsibilities/rights/activities, frequently
asked questions, and handling challenging situations. LHEs will also receive the instruction
to contact the research team if they do not know how to address the problems. The research
team will ask LHEs to respect the privacy of others by keeping confidential any information
they learn about others during meetings and calls.
RCT participants All individuals recruited by the schools will receive an email from the
research team that includes the consent information of the study and a link to the online
baseline survey. They may choose to participate by themselves (individually) or participate
with a family member who meets the eligibility criteria to participate together. Each school
will recruit about 25 individuals. Those who complete the baseline survey will be assigned to
LHE condition or control condition, depending on the group assignment of schools where they
are recruited. Within the two weeks after each participant completes the baseline survey, a
COVID-19 antigen test kit, which FDA authorizes under a EUA, will be provided to each
participant. LHE participants will receive 1) LHE outreach/support (2 small group educational
sessions via Zoom and 2 individual follow-up calls), 2) short video clips via email on the
project overview and the guide to using a test kit (created by the research team in Korean
and English), and 3) test kits with written instructions on COVID-19 testing by Centers for
Disease Control and Prevention (CDC) in English and Korean. LHE outreach small group
educational session is about 1 hour with 2 to 6 people. LHE will present COVID-19 testing and
related information (including vaccination and safety practices). Participants in a dyad
(self-selected participation mode) will attend the educational sessions together. At these
educational sessions, LHE will provide education using PowerPoint presentations with
easy-to-understand messages using culturally appropriate images and simple texts to present
current information on 1) COVID-19 testing; 2) relevance or reasons for getting tested; 3)
the current guidelines for testing/ who should be tested; 4) types of tests available (e.g.,
PCR, antigens, and antibodies tests in forms of nose swap and saliva tests); 5) understanding
test results (positive versus negative) and the limitation of such tests (false negative); 6)
the importance of repeated testing, discussing and addressing barriers for testing. LHE may
assist in helping the participant use a COVID-19 at-home antigen test kit, including
demonstrating the use of the test kit. Participants will be assessed via online survey or by
telephone of their choice at baseline, weeks 4 and 8. Participants will receive up to $70
gift cards for completing all the surveys: $20 for baseline, $20 for week 4, and $30 for week
8. Control participants will receive the same components of the LHE condition except for LHE
outreach/support. All control participants will be assessed at the same schedule: baseline,
weeks 4 and 8. They will receive the same incentives ($70 gift cards for completing all
assessments).
