Efficacy of technology interventions in preventing depression among older adults experiencing social isolation: a...

The global rise in the aging population, intensified by the COVID-19 pandemic, has increased loneliness, social isolation, and depression among older adults. This review aimed to examine the relationships between these psychological challenges and to assess the effectiveness of Information and Communication Technology (ICT)-based interventions in mitigating them.

A systematic review and meta-analysis were conducted following PRISMA guidelines. Studies published within the last five years were retrieved from PubMed, Web of Science, Scopus, and CINAHL. Methodological quality was assessed using CONSORT and STROBE, and quantitative synthesis was performed with RevMan 5.4.1.

Thirteen studies, including experimental and observational designs, met the inclusion criteria; 61.5% analysed pandemic effects and 38.5% evaluated ICT interventions. Depression, loneliness, and social isolation were strongly associated, with the pandemic worsening outcomes, while pre-pandemic isolation predicted poorer mental health. ICT interventions significantly reduced depression (78% reduction; 95% CI 0.15-0.33; OR = 0.22) and anxiety (80% reduction; 95% CI 0.10-0.32; OR = 0.20), though their impact on social isolation was limited (95% CI 0.87-1.19; OR = 1.07).

ICT interventions effectively reduce depression and anxiety but have limited effects on social isolation, highlighting the need for long-term evaluation and community-based strategies to improve emotional well-being in older adults.
