Coping under pressure: police-specific stressors and mental health in Catalonia police forces

IntroductionPolice officers are exposed to elevated psychological risks due to both operational and organizational stressors. Additionally, police officers tend to resort to avoidant coping strategies, which exacerbate poor mental health outcomes, such as burnout and PTSD.MethodsThis study aims to examine clinical symptoms (stress, anxiety, depression), coping styles, and perceived stressors among police forces from Catalonia, Spain. A total of 741 officers completed an online survey comprising DASS-21, PSQ-Op, PSQ-Org, Brief COPE and brief open-ended questions. ResultsOverall, both operational and organizational stressors were significant predictors of clinical symptoms, with the latter revealing a more pronounced impact. Avoidant coping emerged as the strongest risk factor for distress, while problem-focused coping emerged as a possible protective factor, especially against depression. Both gender and years of service influenced coping strategies: i) female officers reported higher use of adaptive coping, while male officers scored higher in avoidant coping; and ii) more experienced officers reported lower anxiety symptoms but also lower use of active coping strategies. DiscussionThese findings underscore the importance of addressing both organizational culture and individual-level factors in promoting psychological resilience, while considering gender and career stage to support sustainable mental health within police forces.

Exposure to negative physical and social factors accelerates brain aging

In a study that included 18,701 people from 34 countries, 73 aggregated physical and social exposomes exhibited nonlinear, synergistic effects that accelerated brain aging. In some cases, these effects were comparable to or stronger than those of mild cognitive impairment and dementia. Environmental inequities might shape brain aging and demand multisectoral and structural policy responses.

Biophysical modeling of excitation/inhibition balance and conversion to psychosis in the clinical high risk syndrome

Reduced mismatch negativity (MMN) and P300 event-related potential (ERP) components are widely replicated in schizophrenia and are also observed in individuals at clinical high risk for psychosis (CHR-P) who subsequently convert to psychosis. It is unknown whether they reflect changes in excitatory and/or inhibitory synaptic function, both implicated in schizophrenia and considered potential drug targets.
