Community Support Systems and Their Influence on Mental Health Outcomes Among Adults

The level of mental health challenges among adults has not been as high as it is worldwide, and thus, there is a need to have a broad insight into protective factors other than clinical interventions. This research examined the links among dimensions of the community support system and mental health outcomes among adults, with social isolation and loneliness as mediators. Researchers gathered data from 487 adults aged 18–84 living in urban, suburban, and rural settings using validated measures of community support (structural, functional, perceived support, and community engagement), social isolation and loneliness, and mental health outcomes, including psychological distress, depression, anxiety, and well-being. Findings showed a high level of negative correlations between mental health symptoms and all of the dimensions of community support (r = -.35 to -.56, p < .001), and perceived support became the strongest predictor. The regression models used in this study were hierarchical and explained 43.5% of the variance in psychological distress. Community support, along with demographics and physical health, explained 21.4% of the variance in psychological distress. Loneliness mediated 63.8% of the effect of perceived support on psychological distress. Age also had a significant moderating effect, with young adults (18-30 years) showing the greatest effect, reporting the highest symptom levels despite having larger networks. The results indicate the robust links between community support and mental health impacts, which implies that the interventions that can improve community ties can be effective and can assist the population with high rates of loneliness and social isolation.
