The advent of large language models (LLM) offers unique advantages to efficiently code affective dream content over human methods, which can be resource intensive and prone to error. This study tested whether dream affect (DA), measured via self-report, human-rated narrative coding, and LLM...
The Hospital Mental Health Risk Screen (HMHRS) predicts risk for negative outcomes following acute trauma, including posttraumatic stress disorder (PTSD). Insomnia and nightmares are common reactions to acute trauma and are considered modifiable risk factors for the development of PTSD. The HMHRS may be useful for detecting risk for post-trauma insomnia and nightmares, however, no studies have...
Study objectives: Patients with acute trauma are vulnerable to suicidality following hospitalization. Research suggests nightmares and insomnia may interact to potentiate suicidality, possibly due to nightmares worsening co-occurring insomnia. Nightmares and insomnia are common stress reactions to acute trauma and might compound suicide risk within acutely traumatized patients. We tested the...
Fear of sleep engenders arousal at bedtime that can promote nightmares. Living in disadvantaged neighborhoods with high rates of community violence may exacerbate fear of sleep and in turn increase nightmare risk. We tested fear of sleep among acute trauma patients as a prospective predictor of nightmares, and whether exposure to community violence moderated this relationship. Patients...
