BACKGROUND:: To assess the long-term (12-month) effects of computerized cognitive stimulation versus stimulating leisure activities in adults with subjective cognitive impairment (SCI) and mild cognitive impairment (MCI).
METHODS:: A 12-month follow-up of a single-blind randomized controlled trial was conducted in primary care centres in Zaragoza, Spain, including 50 adults aged ≥ 50 years with SCI or MCI. Participants were allocated to one of three groups: the computerized cognitive stimulation group (IG1, n=18), the stimulating leisure activities group (IG2, n=16), or a control group (CG, n=16). The primary outcome was global cognitive function; secondary outcomes included memory, verbal fluency, activities of daily living, and mood. Effect sizes were calculated using bootstrapped partial eta-squared (η2p)
RESULTS:: At 12 months, significant between-group differences were observed in depressive symptoms according to the GDS-15 score (p = 0.005, η2p = 0.209) and anxiety levels measured by the Goldberg Index score (p < 0.001, η2p = 0.295). Both intervention groups (IG1 and IG2) showed sustained improvements in depressive symptoms, while anxiety levels remained stable in the intervention groups and worsened in the CG.
CONCLUSIONS:: Participation in computerized cognitive stimulation or stimulating leisure activities associates with sustained, long-term improvements in depressive symptoms and levels of anxiety, supporting the effectiveness of non-pharmacological interventions in primary healthcare.
