• The Impact of Community Violence on Mental Health Outcomes in Urban Populations (2026) · American Journal of Physical Education and Health Science · doi

  This study carries several limitations that should be regarded. First, its cross-sectional nature precludes causal attributions for the effects of exposure to community violence on mental health. It is more difficult to establish the causality of these variables in a cross-sectional design and causes are better examined with longitudinal studies. For a second, the sample may be not totally representative of the general urban population and some groups, such as children or non-residents are better represented than others that can be less populous; thus, there is a potential issue with the external validity. Furthermore, the use of self-reported data may be influenced by reporting bias since participants can under-report or over-report their experiences and symptoms which could affect the accuracy of results. Moreover, although socioeconomic status was accounted for, the survey may not have captured the spectrum of income and resources available to respondents that could impact mental health outcomes in more complex ways. Finally, the focus on urban areas suggests that findings may not pertain to rural and suburban communities in which community violence and its mental health consequences might be different. CONCLUSION The study emphasizes on the profound mental health consequences of community violence exposure in urban environments, especially with PTSD, anxiety, depression and stress. Lifetime exposure to violence, particularly physical assault was found to be associated with increased psychological distress. The role of socioeconomic resource availability and perceived stress on mental health burdens was also revealed to be heightened among the lower-income group. Gender effects on mental health reactions were also observed, as females reported more such as income, status, internalizing signs and symptoms like depression, and males demonstrated increased externalizing behaviors. The results highlight the importance of specific mental health interventions, gender-based strategies and socio- economic support in addressing the psychological impacts of violence. Nevertheless, the lack of a longitudinal design, sample composition and data collection method offer limitations to the study that should lead to future research with regard to community violence in order to deepen knowledge about long term effects of exposure towards mental health.

• A cross-sectional study of depression, emotional intelligence, and Fear of Missing Out among school attending adolescents in Thiruvarur, India (2026) · Discover Public Health · doi

  There are several strengths to this study: our research focused on adolescents from rural and semi-urban areas who are under-represented in mental health studies, and the study evaluates depression, FoMo, and EI levels concurrently. In addition to this, the variables taken into account were socio-demographic and family variables of relevance to the studied population. The sample includes both private and government schools, although no differences were observed. Adequate sample size and robust sampling techniques also need to be mentioned. There are, nevertheless, some limitations to be considered. The associations between the variables are not causal, as causation cannot be proved from a cross-sectional study. There could also be biases associated with self-reported measures. Moreover, since the Velagapalli et al. Discover Public Health (2026) 23:663 Page 14 of 16 study is school-based, it is limited in its generalizability to those who are out of school. There is limited external validity in performing the study only within one district.

• Social Determinants of Anxiety, Worry, and Depression Among Adults in Detroit: Differential Associations Across Outcomes (2026) · Community Mental Health Journal · doi

  The paper identifies a gap in the literature on social determinants of mental health, particularly in urban communities. The study highlights the need to consider socioeconomic and contextual factors in understanding mental health patterns. The research aims to address the limitations of prior studies by using a dataset that intentionally oversamples marginalized neighborhoods and Hispanic-majority census block groups.
