Abstract

Objectives People with Mild Cognitive Impairment (PwMCI) often experience depression and anxiety, which may increase the risk of dementia. While psychological therapy for PwMCI has been explored, the effectiveness of group-based interventions has not. This review systematically examined the methodological quality and effectiveness of group psychological interventions for PwMCI. Method Five databases were searched for studies examining group psychological interventions for PwMCI. Ten studies met the inclusion criteria and were assessed using the Psychotherapy Outcome Study Methodology Rating Form. Interventions were compared by model, length, additional support, and involvement of significant others. A narrative synthesis of the findings was produced. Results Intervention models included Cognitive Behavioural Therapy, mindfulness, self-empowerment-based interventions, a self-efficacy-based intervention, psychosocial (Recovery Model), and an integrative intervention. Outcomes on mood symptoms were reviewed; only six of the 10 studies reported statistically significant improvements. Empowerment-based and self-identity–focused interventions were more frequently associated with reported improvements than other intervention types. Methodological quality was generally low, with substantial heterogeneity in design, outcome measures, and intervention intensity. Conclusion Group psychological interventions show potential for improving mood in PwMCI, particularly empowerment-based approaches. However, methodological weaknesses limit confidence in these findings. Future research should prioritise methodological rigour to clarify the effectiveness of group psychological interventions for PwMCI.
