Nonliterate participants will document their informed consent by marking their ICF(s) (eg, with an X, thumbprint, or other mark) in the presence of a literate third-party witness. Participants will be provided with a copy of their ICF if they are willing to receive it. All minors (under the age of 18) will be required to provide assent along with parental consent. According to Malawi guidelines, individuals aged 15 years and above may initiate Pr EP if they meet other eligibility criteria.

Temporal Dynamics of Subtle Cognitive Change: Validation of a User-Friendly Multidomain Digital Assessment Using an Alcohol Challenge

Respondents are asked to place a mark on the line representing their current feeling of intoxication, and its position is later measured using a ruler to extract a value. The experiment follows a repeated-measures, placebo-controlled (single-blind) crossover within-participant design (see Figure 3). The order of treatment was counterbalanced, such that half of the participants (n=15) received alcohol in their first session and a placebo in their second.
