| Sumario: | • Internet interventions promise to tackle late-life depression. • Internet-based cognitive behavioral therapy was the most common psychotherapy. • Guided-based therapies are more effective and ensure superior adherence than self-directed. • Virtual community can promote communication, support, and collaboration. • Mood and progress tracking, timed reminders, and gamification increased engagement. Depression is prevalent among older adults, and internet-delivered psychological interventions (IDPIs) have emerged as a promising solution. To explore the landscape of IDPIs for late-life depression, examining current characteristics, psychotherapies, intervention strategies, facilitators, and barriers. Guided by a PRISMA-guided scoping review, we systematically searched five electronic databases. 25 relevant studies were identified. IDPIs were used for treatment, prevention, and assessment. Internet-based cognitive behavioral therapy was the most common psychotherapy. Seven strategies to provide tailored services include psychotherapy courses, professional involvement, mood and progress tracking, virtual community, timed reminders, additional learning resources, and gamification elements. Barriers contained cognitive impairment, low digital literacy, device inaccessibility, limited depression awareness, adherence issues, and acclimation time, while facilitators included prior treatment experience, real-life character stories, strong client-worker bonds, and integration into daily care routines. IDPIs present an accessible and convenient avenue for older adults. Future directions suggest exploring minimalist interventions, diverse strategies, and optimized implementation to amplify IDPIs impact among this vulnerable group.
