Older adults living with schizophrenia represent one of the most underserved populations in digital mental health research and practice. Despite growing investment in digital mental health interventions (DMHIs), this population remains largely absent from both their design and evaluation. Existing DMHIs for schizophrenia are predominantly oriented toward clinical outcomes, emphasising positive symptom monitoring and relapse prevention, while comparatively little attention is given to negative symptoms and the functional impairments that carry a more enduring and debilitating impact across later life. This reflects a broader pattern in schizophrenia care in which measurable symptom outcomes are prioritised over the functional, psychosocial, and identity-related dimensions (i.e., social connection, purpose, autonomy, and functional independence) of recovery that older adults themselves identify as central to their wellbeing. Where personalisation has been incorporated into DMHIs, it has typically been narrowly conceived, focusing on tailoring delivery formats or optimising treatment adherence rather than responding to the values, goals, and lived experiences of the individual. This conceptual paper argues for a fundamental reconceptualisation of personalisation in DMHIs, not as a mechanism for enhancing clinical outcomes, but as a pathway for supporting functional capacity and meaningful recovery among older adults with schizophrenia. We contend that shifting from clinically driven to functionally oriented personalisation has the potential to address a persistent and under-recognised gap in the DMHI landscape. The absence of digital interventions that are both responsive to the needs of this population and meaningfully aligned with what recovery looks like for them.
