Abstract

Study objectives To investigate emotion regulation difficulties in association with self-reported insomnia symptoms, nightmares, and depression symptoms in a sample of current and retired firefighters.Methods A total of 880 current and retired United States firefighters completed a web-based survey of firefighter behavioral health. Self-report measures included the Center for Epidemiologic Studies Depression Scale, Insomnia Severity Index, PTSD Checklist, and Difficulties in Emotion Regulation Scale.Results A notable portion of participants reported clinically significant depression symptoms (39.6%) and insomnia symptoms (52.7%), as well as nightmare problems (19.2%), each of which demonstrated a strong association with emotion regulation difficulties (rs = 0.56-0.80). Bootstrapped mediation analyses revealed that the indirect effects of overall emotion regulation difficulties were significant both for the relationship between insomnia and depression (95% CI: 0.385-0.566) and nightmares and depression (95% CI: 1.445-2.365). Limited access to emotion regulation strategies emerged as the strongest, significant indirect effect for both relationships (insomnia 95% CI: 0.136-0.335; nightmares 95% CI: 0.887-1.931).Conclusions Findings extend previous affective neuroscience research by providing evidence that insomnia and nightmares may influence depression symptoms specifically through the pathway of explicit emotion regulation difficulties. Sleep disturbances may impair the ability to access and leverage emotion regulation strategies effectively, thus conferring risk for negative affect and depression.

  • Mental health conditions common in firefighters include PTSD, depression, anxiety, and substance abuse, which may cause a greater risk for suicidal thoughts and attempts.

    “Mental health conditions common in firefighters include post-traumatic stress disorder (PTSD), depression, anxiety, and substance abuse which may cause a greater risk for suicidal thoughts and attempts [7,29,30,31].”

    From The Cyclical Battle of Insomnia and Mental Health Impairment in Firefighters: A Narrative Review (2024) · cites this paper as [30]

    The Introduction (page unavailable) says firefighters are at elevated risk for depression, and the study reports high rates of depressive symptoms. It links suicidal ideation and behaviors to nightmares and insomnia, not to the listed mental health conditions. The cited paper does not establish that PTSD, anxiety, and substance abuse are common in firefighters or that those conditions increase their risk of suicidal thoughts and attempts. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Estimates of depression prevalence in firefighter populations are significantly higher than the general population, for example 40%.

    “A large study estimates the 12-month depression prevalence to be between 5.5 and 6.0% in the general population [57] where estimates are significantly higher in firefighter populations (e.g., 40% [30]).”

    From The Cyclical Battle of Insomnia and Mental Health Impairment in Firefighters: A Narrative Review (2024) · cites this paper as [30]

    The Results (Descriptive Statistics; page unavailable) report that 39.6% of the 880 firefighters surveyed had clinically significant depression symptoms, supporting the approximate 40% figure. The paper does not establish a 40% prevalence of diagnosed depression in firefighter populations or test whether it is significantly higher than general-population prevalence; Limitations and Future Directions notes that the convenience sample may limit generalizability. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Individuals with significant mental health symptoms are at an increased risk of encountering negative emotional states and are less equipped to effectively cope with them, leading to decreased sleep quality and insomnia.

    “Thus, individuals are at an increased risk of encountering negative emotional states and are less equipped to effectively cope with them, leading to decreased sleep quality and insomnia [30].”

    From The Cyclical Battle of Insomnia and Mental Health Impairment in Firefighters: A Narrative Review (2024) · cites this paper as [30]

    The Discussion (page not provided) suggests that depression may impair the ability to acknowledge and respond to negative emotions, subsequently affecting sleep quality. The Results (page not provided) also report an association between depression, emotion-regulation difficulties, and insomnia severity. The study examined firefighters, however, and does not establish that individuals generally encounter negative emotional states more often or that these difficulties cause insomnia. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Approximately one-third of emergency responders meet criteria for other common mental health disorders such as depression, anxiety, and sleep disorders.

    “approximately one-third of emergency responders meet criteria for other common mental health disorders such as depression, anxiety, and sleep disorders (1, 5, 15–18).”

    From Pilot outcomes and exploration of treatment mechanisms using a culturally adapted version of the unified protocol for transdiagnostic treatment of emotional disorders to improve mental health symptoms, alcohol misuse, functional outcomes, and sleep quality in emergency responders (2025) · cites this paper as [17]

    The Results (Descriptive Statistics; page unavailable) report clinically significant depression symptoms in 39.6% and insomnia symptoms in 52.7% of the firefighter sample. The paper does not establish that approximately one-third of emergency responders meet diagnostic criteria for depression, anxiety, and sleep disorders: it studied firefighters, reported symptoms rather than diagnoses, and did not report an anxiety-disorder rate. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • In subsequent studies with fire fighters, difficulties in emotion regulation accounted for the link between depression and insomnia and were linked with PTSD symptom severity, sleep difficulties, and alcohol use.

    “In subsequent studies with fire fighters, difficulties in emotion regulation accounted for the link between depression and insomnia and were linked with PTSD symptom severity, sleep difficulties, and alcohol use (16, 17, 57–59).”

    From Pilot outcomes and exploration of treatment mechanisms using a culturally adapted version of the unified protocol for transdiagnostic treatment of emotional disorders to improve mental health symptoms, alcohol misuse, functional outcomes, and sleep quality in emergency responders (2025) · cites this paper as [17]

    The Abstract reports significant indirect effects of emotion regulation difficulties on the insomnia–depression relationship in current and retired firefighters, and an association with sleep difficulties. The cited paper does not report a link between emotion regulation difficulties and PTSD symptom severity or alcohol use; those parts of the sentence are not supported by this source.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
