1.2.2. Qualitative Study

The qualitative study was initially open only to participants in Conditions 3 or 4 of the parent study, and later included two participants in Condition 2 due to delays experienced by the COVID-19 pandemic. Twenty-two participants were invited to participate in a semi-structured interview, conducted in English, as they completed the parent study (at Weeks 14–16) or at the time of parent study withdrawal. Twenty chose to participate. Interviews were conducted from March 2020 through May 2021 (enrollment was paused during a 6-month period due to the COVID-19 pandemic). The first two interviews were conducted in person and subsequent interviews were conducted over the phone due to social distancing restrictions. Institutional Review Board approval was granted by Brown University. Participants received $40 as compensation for their time.
