“…Hence, understanding the psychological mechanisms that underlie the relationship between traumatic event exposure and suicidal ideation could reveal new promising targets for suicide prevention. Consistent with previous studies ( Andrews and Hanna, 2020 Li et al, 2010 ; Littlewood et al, 2017 ; Russell et al, 2019 ;), we also found that nightmares were an independent risk factor for suicidal ideation in different CTE exposure groups but not other factors (i.e., symptoms of depression, anxiety, and insomnia) after controlling potential confounders. The potential reason of this finding might be that the multi-collinearity of nightmares co-occurs with other psychopathological symptoms in clinical.…”

“…Nightmares are an important contributing factor to suicidality, which has a small-to-medium effect for prospective suicidal ideation (d = 0.40) and a medium effect for subsequent suicide attempts (d = 0.64) and suicide death (d = 0.50) ( Liu et al, 2020 ). Emotional dysregulation and negative cognitive appraisals are factors that underlie the relationship between nightmares and suicidality ( Andrews and Hanna, 2020 ). Previous research indicated that interventions that target nightmares may lower suicide risk.…”

“… 6 Sleep disorders are also a determining factor in suicide risk and are frequently cited. 7 The Substance Abuse and Mental Health services Administration and the American Association of Suicidology consider sleep disorders as one of the 10 warning signs of suicidal risk. 8 According to the literature, this association ranges between a relative risk of 1.95 and 2.95.…”

Objective Nightmare distress, nightmare frequency and anxiety are related to suicidal risk. Ruminations are a factor maximizing the risk of suicide. Research has identified two types of ruminations: constructive ruminations and non-constructive ruminations. As per our knowledge, no study has verified the links between non-constructive ruminations and sleep disorders and their role in the development of suicidal risk. We aimed to highlight the impact of non-constructive ruminations on nightmares, anxiety and insomnia in the development of suicidal risk. Methods A total of 429 French participants responded to an anonymous online survey using the Qualtrics ® software. To assess variables, we used the Mini Cambridge-Exeter Repetitive Thought Scale, the Suicide Behaviors Questionnaire-Revised, the Nightmare Distress Questionnaire, the Beck Anxiety Inventory, and the Sleep Condition Indicator. Nightmare frequency was assessed by subjective evaluation through a question. We tested the possible effects of confounding variables such as age, gender, marital status and depression (Beck Depression Inventory-II). Results Nightmare frequency was found to mediate the link between anxiety and suicidal risk (32.9%). Nightmare distress (37%) and non-constructive thoughts (48%) were also seen to mediate this link. Additionally, we found a moderating effect of insomnia on the link between non-constructive ruminations and suicidal risk (Z = 7.42, p < 0.001). Conclusion Our results showed that the frequency of nightmares, distress and non-constructive ruminations are closely related to suicidal risk. The interoperability between these elements and insomnia has thus been newly explored. The processes related to nightmares and suicidal risk as well as the underlying cognitive processes between sleep disorders and suicidal risk have been shed light upon.

“…Frequent nightmares (i.e., at least weekly) are reported by 2% to 6% of nonclinical samples of adults (Levin & Nielsen, 2007; Sandman et al, 2013). They are associated with decreased well-being (Blagrove et al, 2004), increased suicidality (Andrews & Hanna, 2020), and functional impairments on days following nightmares (Lancee & Schrijnemaekers, 2013).…”

Elucidating nightmare proneness: Relationships with emotional dysregulation and psychological vulnerability.

Previous research found that nightmare proneness, a personality disposition to experience frequent nightmares, independently predicted nightmare occurrences after accounting for maladjustment. However, mechanisms involved in the nightmare proneness construct are not well understood. The current study examined a model in which vulnerability and emotional dysregulation influenced nightmare proneness among 143 university students. Consistent with the model, vulnerability and emotional dysregulation independently predicted nightmare proneness after accounting for distress and gender. Only nightmare proneness accounted for unique variance in nightmare frequency, but vulnerability and emotional dysregulation influenced nightmare frequency indirectly through nightmare proneness. The results and suggestions for future research were discussed.
