Background: Tai Chi exercise is a non-pharmacological therapy that has received increased attention in recent years. A Tai Chi program has been specifically modified for older people with cognitive impairments by the research team. Objective: We aim to assess the effects of this Tai Chi program on mild dementia. Methods: Eighty older people with mild dementia were recruited and randomly assigned to a Tai Chi group or a control group. The Tai Chi group practiced the Tai Chi program three times a week for 10 months, while the control group continued receiving routine treatments. All participants were assessed for cognitive function, behavior/mood, and activities of daily living at baseline, 5 months, and 10 months. Results: The Tai Chi group performed better than the control group. Repeated measures ANOVA revealed a significant group × time interaction in the Montreal Cognitive Assessment (MoCA). Further analysis of sub-items of the MoCA showed a significant time effect in naming and abstraction. It was statistically significant in both main effect of time and group × time interaction in the Neuropsychiatric Inventory (NPI) and Geriatric Depression Scale (GDS). Paired sample t test showed the Tai Chi group scored lower at 5 and 10 months in the NPI and at 10 months in the GDS compared with baseline. The Tai Chi group scored lower than the control group at 10 months in the NPI and GDS. Conclusion:The results suggest this Tai Chi program may help improve cognitive function and mental well-being for older adults with mild dementia.
Background: Recent studies report that hospital staff at the forefront of caring for COVID-19 patients experience increased psychological distress. To effectively manage the outbreak of COVID-19, China established COVID-19 designated and non-designated hospitals. To date, few studies have examined the impacts of COVID-19 on psychological health of staff working at non-designated hospitals. This study is to explore factors affecting psychological health of non-designated hospital staff in China during the COVID-19 pandemic.Methods: Data were collected through an online questionnaire between February and March 2020. The questionnaire consists of General Health Questionnaire (GHQ-20), Social Support Rating Scale (SSRS), Simplified Coping Style Questionnaire (SCSQ), sociodemographic characteristics, employment history, health status, and contact history of COVID-19. The questionnaire was distributed through hospital WeChat groups and work colleague referrals. A total of 470 non-designated hospital staff members completed the questionnaire. Multiple Linear Regression analysis was used to interpret the associations among social support, coping styles, sociodemographic factors, job roles, and psychological status. Data were analyzed using SPSS version 21.0.Results: The non-designated hospital staff differed significantly in anxiety and depression subscores of the GHQ-20 by their job roles, levels of social support, and history of mental disorders. Staff with medical job roles, good self-reported health status, no previous mental disorders, adequate social support, and positive coping styles scored lower in GHQ-20 total score, which indicated healthier psychological status.Conclusions: The results indicate that history of mental health disorders, non-medical job roles, and inadequate social support are associated with greater psychological distress. Personalized support should be provided to those who are vulnerable and in need of social and psychological support.
Discussion: This protocol outlines the objectives of the study and explained the RLT device developed by the research team. The study is designed as an RCT to evaluate the safety and effects of the RLT device on older adults with mild to moderate AD. This study will provide evidence for the clinical use of RLT on treatment for AD.
