Randomization and allocation
Participants were randomly allocated in a 2:1 ratio to either the diary intervention or to the control group. This was accomplished by shuffling 16 opaque, sealed envelopes, 11 of which allocated participants to the diary intervention and 5 of which allocated participants to the control group. Allocation remained fully concealed until participants provided verbal informed consent, after which study staff opened the envelopes containing the randomization assignment and informed the participant of their allocation. After this point, due to study design and resource limitations, family members, outcome assessors, and data analysts were aware of allocation. The same study staff were responsible for randomization generation, allocation, and enrollment.
