Designing a User-Centered Mobile App to Foster Intergenerational Communication Between Older and Younger Adults: Applying the Double Diamond Design Framework
ABSTRACT
Background:
Social isolation and weakened intergenerational ties pose significant threats to the emotional well-being and social support networks of older adults. Although structured intergenerational programs can reduce age-related stereotypes and promote connectedness, their accessibility is often hindered by physical and logistical constraints. The increasing digital literacy among older populations presents new opportunities for technology-based interventions to support meaningful cross-generational engagement.
Objective:
This study aimed to design and evaluate a mobile application that fosters intergenerational communication and enhances perceived social support in older adults, using a user-centered design framework grounded in the Double Diamond model.
Methods:
The development process followed the four phases of the Double Diamond model. In the Discover phase, surveys with older and younger adults identified distinct usability preferences. The Define phase synthesized these insights into key design principles. In the Develop phase, a prototype was created and iteratively refined through usability testing. Finally, in the Deliver phase, a two-week experimental study involving 39 participants (20 older adults aged 68–82, and 19 younger adults aged 22–39) assessed changes in intergenerational interaction, perceived social support, and user satisfaction.
Results:
The app significantly enhanced intergenerational communication and perceived social support, particularly among older participants. Users reported increased comfort and emotional connection in cross-generational conversations. Accessibility features and engaging content contributed to positive user experiences across age groups.
Conclusions:
This study highlights the potential of user-centered, digital platforms to promote social well-being among older adults. By addressing the unique needs of multiple generations, such interventions can foster inclusive digital environments and contribute to age-friendly, connected societies.
