A Trial of Combined Subthreshold Depression in Older Adults With Mild Cognitive Impairment Participating in Art Games

Subthreshold depression is a psychological sub-health state between normal psychological state and depression, and the existence of subthreshold depressive symptoms accelerates the quality of life decline and cognitive impairment in older adults with mild cognitive impairment, increasing the rate of dementia conversion, while the continuous decline of cognitive function will, in turn, accelerate the deterioration of depression. In recent years, there has been an increase in the attention paid to depression in people with mild cognitive impairment in China, but because subthreshold depression is currently difficult to recognize, research on subthreshold depression in people with mild cognitive impairment is still in the initial stage, and therefore more attention needs to be paid to this population to achieve early detection and intervention, otherwise, these older adults will be in a vicious cycle of worsening depression symptoms and accelerated cognitive decline, and their physical and mental health will be continuously Otherwise, these older adults will be in a vicious cycle of worsening depressive symptoms and accelerated cognitive decline, and their physical and mental health will be continuously damaged. Art therapy is one of the effective non-pharmacological interventions widely used in dementia and psychological care. Current art therapies are mostly in the form of offline interventions, and most participants may be poorly motivated to participate due to factors such as spatial distance, financial benefits, or lack of interest. More and more interventions, in order to enrich the interest of the study and improve the participant's motivation to participate, have begun to use online video game design with embedded gamification elements in their interventions to better help improve cognitive function and physical and mental health of older adults. Thus, incorporating online art games may become a new form of health intervention for older adults. This project constructs an online art game intervention program for older adults with mild cognitive impairment combined with subthreshold depression based on self-determination theory, and recruits older adult participants from nursing facilities to conduct a three-month randomized controlled trial using a scale to assess the health status of participants, with the aim of providing new evidence and ideas for the prevention and treatment of older adults with mild cognitive impairment combined with subthreshold depression in the high-risk population of older adults in China. The results of the study will provide theoretical and practical basis for personalized intervention for older adults with mild cognitive impairment combined with subthreshold depression.
