A Culturally Appropriate Multimodal Non-pharmacological Intervention for Chinese People With Mild-to-Moderate Dementia

Dementia is a disabling chronic condition affecting over 47 million people worldwide. Chinese population will be one of the main driver in the increasing trend in dementia prevalence. Accumulating evidence suggests effectiveness of certain non-drug interventions in maintaining cognition and quality of life in people with mild-to-moderate dementia, such as cognitive stimulation therapy (CST). These interventions are designed and tested in western populations with issues of cultural adaptation when applied in Chinese. Culturally appropriate and effective interventions for Chinese people with mild-to-moderate dementia are lacking.

The Six Arts stem from ancient Confucian philosophy, which promotes behaviours that can impact on multiple mind-body functional domains. These domains correspond to social, physical, and cognitive activities with theoretical basis and empirical evidence of benefits in cognition, functioning, and quality of life. Using the Six Arts as a cultural framework, a group-based multimodal intervention has been developed in Hong Kong for Chinese people with mild-to-moderate dementia.

The study will recruit 240 people with mild-to-moderate dementia in a randomized single-blind controlled trial consisting of three groups: (1) Six Arts intervention; (2) CST; and (3) usual care. Neuropsychological and clinical assessments will be conducted at randomization (T0/baseline) and upon completion of the 24-session, twice-weekly intervention (T1/3 months), by an assessor unaware of group membership. Focus groups will be conducted after completion of the intervention in 60 family caregivers who have observed at least one session of the Six Arts intervention or CST.

This study will provide evidence on the effectiveness of two intervention protocols with potentials for large-scale implementation in the growing Chinese population with dementia.
