Flow chart of literature search. Adapted from PRISMA 2009 Flow Diagram (Moher, Liberati, Tetzlaff, Altman, & The Prisma Group, 2009). 107 articles were excluded following full-text screening because they did not meet the inclusion criteria. The most common reasons for exclusion at this stage were: HIV-infected population, ‘extreme’ stressor, onset of infection precedes psychosocial stressor, and not relating to infectious disease.
