ObjectivesCognitive reserve provides evidence in the search for answers regarding the role that lifestyle has in theprotection of cognition in old age. Through a structural equations model, different things were analyzed: therelative weight of education, occupational complexity, free time activities and the intelligence quotient incognitive reserve; and its impact on three cognitive domains: memory, language and executive functions.DesignA trail analysis was executed, using structural equations procedure.Participants167 older participants (mean = 76.74 years, standard deviation = 6.8 years).MeasurementsParticipants were assessed with: Sociodemographic Questionnaire, Occupational Activity AgencyQuestionnaire, Social Participation Questionnaire and Neuropsychological Evaluation Battery for: memory,language and executive functions.ResultsThe cognitive reserve factor is well represented by the measures included, with values between .43 and .86,and shows a direct effect on language (β = .52, p < .001), executive functions (β = .77, p
