The preliminary evidence summarized in this narrative review indicates that positive psychiatry interventions targeting social connectedness, meaning in life, wisdom, and resilience can improve overall well-being and other positive health outcomes amongst older adults. The effect sizes of these interventions reported in RCTs and meta-analyses are typically small to medium, but occasionally large effect sizes are also reported. Current literature is restricted by heterogeneous methodology, limiting clinicians' abilities to extrapolate these principles of positive psychiatry into everyday practice. With the expanding body of evidence, positive psychiatry may have the potential to transform the landscape of geriatric mental health.
