PTSD and challenges among older Chinese in Shenzhen during COVID-19 pandemic: Trust in authority and medical professionals as moderators

Higher levels of challenges related to 'supplies, services access and safety', 'abuse and conflicts', and 'anger and fear' were associated with PTSD. Furthermore, a lower level of challenges related to 'disease management and information' was associated with PTSD. Trust in authority or medical professionals was the moderator between the challenges brought about by COVID-19 and PTSD, which helped to lower the impact of challenges. Despite the challenges brought by COVID-19 to people, nurturing a stronger sense of trust in authority and medical professionals would ease older adults' psychological stress and concerns.
