Residential aged care homes are increasingly central spaces of later life, yet residents commonly experience loneliness, psychological distress, and depressive symptoms. As the ageing population grows, there is a need for accessible, evidence‑based psychosocial interventions that support wellbeing alongside physical care. This presentation reports findings from a pilot evaluation of The Memory Collective, a clinician‑facilitated group reminiscence program delivered in residential aged care homes in Victoria, Australia. A single-arm pre-post study was conducted with 22 residents across three facilities, with participants attending six to eight weekly group sessions. Quantitative measures assessed changes in psychological distress, depressive symptoms, and loneliness, while open-ended questions explored participants’ experiences and perceived benefits of the program. Results indicated statistically significant reductions in psychological distress, depressive symptoms, and loneliness following participation. Program acceptability was high, with over 90% of participants reporting that the group was helpful and that it improved their coping and confidence in decision‑making. Qualitative analysis identified four interconnected mechanisms underpinning these outcomes: hearing others’ stories; telling one’s own story; finding commonalities with group members; and socialising with others. Participants emphasised the importance of social connection, belonging, and being heard within the group context. These findings suggest that clinician‑led reminiscence groups are acceptable and beneficial for improving psychosocial wellbeing among older adults living in residential aged care. The study highlights the value of structured group‑based interventions in addressing emotional and social needs within institutional care settings, contributing to broader discussions about quality of life and person‑centered care in an ageing society.
