 This study examined the adoption of social networking sites, SNS, by older adults in Chile. It found that there are three distinct segments of older adults based on their technology readiness levels. These segments included independent elders, technological apathetic elders, and technological eager elders. The study also showed that the elderly's technology readiness level was related to their intention to use SNS. This suggests that tailored interventions should be developed for each segment to increase the adoption of SNS by the elderly. This article was authored by Patricio E.
