Introduction: prospective memory is the ability to remember actions in the future or remember delayed intentions.
Objective: to study the relationship between prospective memory complaints with an objective measure of prospective memory and affective-emotional variables such as depression and anxiety.
Subjects and materials: 51 patients with multiple sclerosis relapsing-remitting and 46 participants in the control group were evaluated with a prospective memory task called El Condor, a questionnaire on subjective complaints of prospective memory, a depression inventory and an anxiety inventory.
Results: the control group performed better in El Condor than patients with multiple sclerosis, t = 6263, df = 95, p = 0.000. The prospective memory questionnaire correlated with the depression and the anxiety inventories, but not with El Condor.
Conclusions: subjective prospective memory is associated with depression and anxiety and not with the objective prospective memory in a group of multiple sclerosis patients. The results indicate that the subjective and objective prospective memory must be studied as separate entities or different phenomena.
