The COVID-19 pandemic has exacerbated health inequalities, with a potentially heightened mental health risk for Mainland Chinese in Canada, given the rising anti-Chinese discrimination, and barriers in assessing health services. In this context, this study aimed to assess non-pathological psychological distress towards COVID-19 and identify its sociodemographic risk factors among Mainland Chinese in Canada at the early stages of the pandemic. Methods: A sample of 731 Mainland Chinese aged 16 or older completed an on-line survey to examine their attitudes, behavioural, and psychological responses towards COVID-19. Non-pathological psychological distress was assessed with a 7-item self-report scale to capture common emotional reactions towards COVID-19. Results: A factor analysis revealed a single-factor structure of the 7-item COVID-19 psychological distress scale (Eigen λ = 3.79). A composite psychological distress index (PDI) score was calculated from these items and used as the outcome variable. Multivariate regression models identified age, financial satisfaction, health status, and perceived/experienced discrimination as significant predictors of psychological distress (ps ≤ 0.05). Conclusions: Mainland Chinese in Canada who were over 25, in poor financial/health status, or with perceived/experienced discrimination were at a higher risk for COVID-19-related psychological distress. The health inequity across these factors would inform the services to mitigate mental health risk in minority groups.

The dual mechanisms of control framework (DMC) proposes two modes of cognitive control: proactive and reactive control. In anticipation of an interference event, young adults primarily use a more proactive control mode, whereas older adults tend to use a more reactive one during the event, due to age-related deficits in working memory. The current study aimed to examine the effects of mood induction on cognitive control mode in older (ages 65+) compared to young adults (ages 18–30) with a standard letter-cue (Experiment 1) and a modified face-cue AX-CPT (Experiment 2). Mood induction into negative and/or positive mood versus neutral mood was conducted prior to the cognitive control task. Experiment 1 replicated the typical pattern of proactive control use in young adults and reactive control use in older adults. In Experiment 2, older adults showed comparable proactive control to young adults in their response time (RT). Mood induction showed little effect on cognitive control across the two experiments. These results did not reveal consistent effects of mood (negative or positive) on cognitive control mode in young and older adults, but discovered (or demonstrated) that older adults can engage proactive control when dichotomous face cues (female or male) are used in AX-CPT.

Several measures have been implemented to reduce the spread of the COVID-19, with mask-wearing among the most widely used measures. Yet, the barriers to mask-wearing are unclear. This study examined whether different types of anxiety symptom clusters (i.e., symptoms of claustrophobia, physical anxiety sensitivity, and social anxiety sensitivity) are associated with mask-wearing tendencies during the COVID-19 pandemic and investigated how anxiety symptom clusters relate to mask-wearing discomfort and selfisolation distress. A total of 556 Canadian adults were recruited online between January and February of 2021. The study was administered online via Qualtrics. Participants completed questionnaires measuring symptoms of claustrophobia, anxiety sensitivity, and isolation distress, along with a measure of maskwearing behaviours. Linear regression analyses revealed that elevated anxiety symptoms across all symptom clusters predicted more physical and emotional discomfort related to mask-wearing, as well as reduced likelihood of leaving the home due to mask-related discomfort. Leaving home less often due to mask-related discomfort was significantly associated with more self-isolation distress and poorer coping overall. Differential patterns of mask-wearing behaviours across anxiety symptom clusters were not detected. These findings suggest that anxiety symptoms (i.e., including claustrophobia, physical anxiety sensitivity, and social anxiety sensitivity) are positively associated with mask-related distress. This, in turn, may lead people to avoid leaving their home and consequently experience increased self-isolation distress. Furthermore, these findings suggest that people with heightened anxiety symptoms tend to experience more discomfort with mask-wearing, which may perpetuate a cycle of avoidance and poorer coping overall. Public Significance StatementThe findings suggest that anxiety symptoms may interfere with engagement in this important public health measure, informing policy-makers of at-risk groups in the population. Moreover, those who experience higher mask-related anxiety are more likely to stay at home, leading to increased self-isolation and isolation-related distress.
