Hong Kong youth and young adults experienced unprecedented stress amid social unrest and the COVID-19 pandemic. Few studies have examined how these stressors were related to psychological distress among youth and young adults. This study assessed how psychological distress is associated with stress from social unrest, financial circumstances, and the COVID-19 pandemic, and whether poor sleep quality may explain these associations. Participants of a representative phone survey included 1,501 Hong Kong youth and young adults (Mage = 26.1 (4.0); 48.2% female). We examined the associations between psychological distress and three types of stress (social unrest, financial, and COVID-19 stress), and the indirect effect of poor sleep. Eleven point nine percent, 4.1%, and 9.7% of respondents reported feeling very seriously distressed by social unrest, financial circumstances, and the COVID-19 pandemic, respectively. All three forms of stress were associated with poor sleep. The indirect effects of poor sleep on the association between all three forms of stress and psychological distress were identified. Moderated indirect effect analysis indicated that being female intensified the effect of COVID-19-related stress on psychological distress and that younger female youth and older male youth were more vulnerable to financial stress and social unrest stress (vs. older female youth and younger male youth). Sleep may be one mechanism that accounts for the association between psychological distress and protracted stressors among Hong Kong youth and young adults. These results suggest the importance of prioritizing sleep improvement in mental health interventions during times of societal change.
