Abstract

Although research on neighborhood effects has shown positive outcomes of collective efficacy in mental health, few studies have examined whether its protective role is universally applicable to all residents or the vulnerable population. Building on a stress-buffering model, this study examines whether or not neighborhood collective efficacy serves as a stress buffer to ameliorate the deleterious effects of exposure to stressful events across different population groups. Analyses are conducted based on a city-wide representative sample in Hong Kong linked to suicide events through spatial and temporal information. Neighborhood-level collective efficacy is constructed by the aggregated mean score of individual perceived collective efficacy within the same residential neighborhoods.

RESULTS from the logistic regression models show that individuals exposed to suicide in the residential surroundings have a higher risk of mental distress symptoms. Moreover, neighborhood-level collective efficacy tends to alleviate the mental distress upon exposure, but such a stress-buffering effect is only observed in older adults. Our findings provide a new perspective informed by the variation of stress-buffering effect across population groups. Thus, this study contributes to the understandings of neighborhood collective by demonstrating the stress-buffering effects among the vulnerable population.
