In this study, an ecological model and developmental psychopathology theory focusing on an ontogenic system (hopelessness) and microsystems (peer alienation and childhood abuse and trauma) was adopted to examine the individual, peer, and family correlates of depressive symptoms among college Chinese students in Hong Kong, China. A cross-sectional survey research design with a convenience sampling procedure was used to examine a sample of college students (n = 786) aged 18 to 21 years old in Hong Kong. Among them, 352 respondents (44.8%) reported having depressive symptoms, with a Beck Depression Inventory-II (BDI-II) score of 14 or above. The results of this study indicated that childhood abuse and trauma, peer alienation, and hopelessness were positively related to depressive symptoms. The underlying arguments and implications were discussed. The study results provided further support for the ecological model and the developmental psychopathology theory on the predictive roles of individual, peer, and family correlates of adolescent depression.

Background: This study explores the multifaceted inequalities faced by informal waste pickers in Hong Kong, focusing on the impacts of gender and socioeconomic status in shaping their working environment, income, and psychological health. Recognizing that social stratification encompasses a series of structural factors, i.e., gender, race, and socioeconomic status, we aim to fill the gap in existing literature regarding the precarious employment of this population. Methods: Utilizing a comprehensive, territory-wide survey, we analyzed the experiences of male and female waste pickers across different socioeconomic backgrounds. Differences between genders for continuous variables were assessed using the independent samples t-test. Differences across categories defined by gender and socioeconomic status were analyzed using one-way ANOVA, followed by post hoc comparisons with the least significant difference (LSD) method. Results: Our findings indicate that both gender and socioeconomic status significantly influence working environment, occupational income, and psychological health outcomes. Specifically, female waste pickers from lower socioeconomic backgrounds face more adverse working environments, lower income levels, and heightened psychological health risks compared to their higher-status counterparts. Conclusions: These results underscore the urgent need for targeted outreach and tailored healthcare services for vulnerable female waste pickers, as well as social support systems that empower them to negotiate with intermediaries and recycling shop owners. By recognizing their essential role in Hong Kong’s urban recycling ecosystem, this study advocates for policies that address these disparities and promote psychological health and social well-being among this marginalized group.
