This study used a conceptual replication design to determine whether cognitive intraindividual variability, as measured by dispersion (IIV-dispersion), contributes to PM performance and symptoms among PLWH.<\/jats:p><\/jats:sec><jats:sec id=\"S1355617722000698_as2\"><jats:title>Methods:<\/jats:title><jats:p>Study 1 included 367 PLWH who completed a comprehensive clinical neuropsychological test battery, the Memory for Intentions Test (MIsT), and the Prospective and Retrospective Memory Questionnaire (PRMQ). Study 2 included 79 older PLWH who completed the Cogstate cognitive battery, the Cambridge Prospective Memory Test (CAMPROMPT), an experimental measure of time-based PM, and the PRMQ. In both studies, a mean-adjusted coefficient of variation was derived to measure IIV-dispersion using normative<jats:italic>T<\/jats:italic>-scores from the cognitive battery.<\/jats:p><\/jats:sec><jats:sec id=\"S1355617722000698_as3\"><jats:title>Results:<\/jats:title><jats:p>Higher IIV-dispersion was significantly associated with lower time-based PM performance at small-to-medium effect sizes in both studies (mean<jats:italic>r<\/jats:italic><jats:sub><jats:italic>s<\/jats:italic><\/jats:sub>\u00a0=\u00a0\u22120.30). The relationship between IIV-dispersion and event-based PM performance was comparably small in magnitude in both studies (<jats:italic>r<\/jats:italic><jats:sub><jats:italic>s<\/jats:italic><\/jats:sub>\u00a0=\u00a0\u22120.19, \u22120.20), but it was only statistically significant in Study 1.
