ABSTRACT: Sleep disturbances are a hallmark feature of post-traumatic stress disorder (PTSD), and associated with poor clinical outcomes. Few studies have examined sleep quantitative electroencephalography (qEEG), a technique able to detect subtle differences that polysomnography does not capture. We hypothesized that greater high-frequency qEEG would reflect 'hyperarousal' in combat veterans with PTSD (nā€ƒ=ā€ƒ16) compared to veterans without PTSD (nā€ƒ=ā€ƒ13). EEG power in traditional EEG frequency bands was computed for artifact-free sleep epochs across an entire night. Correlations were performed between qEEG and ratings of PTSD symptoms and combat exposure. The groups did not differ significantly in whole-night qEEG measures for either rapid eye movement (REM) or non-REM (NREM) sleep. Non-significant medium effect sizes suggest less REM beta (opposite to our hypothesis), less REM and NREM sigma and more NREM gamma in combat veterans with PTSD. Positive correlations were found between combat exposure and NREM beta (PTSD group only), and REM and NREM sigma (non-PTSD group only). Results did not support global hyperarousal in PTSD as indexed by increased beta qEEG activity. The correlation of sigma activity with combat exposure in those without PTSD and the non-significant trend towards less sigma activity during both REM and NREM sleep in combat veterans with PTSD suggests that differential information processing during sleep may characterize combat-exposed military veterans with and without PTSD.

2 Article An emergency department intervention for linking pediatric suicidal patients to follow-up mental health treatment. 2011

ABSTRACT: OBJECTIVE: Suicide is the third leading cause of death among adolescents. Many suicidal youths treated in emergency departments do not receive follow-up treatment as advocated by the National Strategy for Suicide Prevention. Two strategies for improving rates of follow-up treatment were compared. METHODS: In a randomized controlled trial, suicidal youths at two emergency departments (N=181; ages ten to 18) were individually assigned between April 2003 and August 2005 to one of two conditions: an enhanced mental health intervention involving a family-based cognitive-behavioral therapy session designed to increase motivation for follow-up treatment and safety, supplemented by care linkage telephone contacts after emergency department discharge, or usual emergency department care enhanced by provider education. Assessments were conducted at baseline and approximately two months after discharge from the emergency department or hospital. The primary outcome measure was rates of outpatient mental health treatment after discharge. RESULTS: Intervention patients were significantly more likely than usual care patients to attend outpatient treatment (92% versus 76%; p=.004). The intervention group also had significantly higher rates of psychotherapy (76% versus 49%; p=.001), combined psychotherapy and medication (58% versus 37%; p=.003), and psychotherapy visits (mean 5.3 versus 3.1; p=.003). Neither the emergency department intervention nor community outpatient treatment (in exploratory analyses) was significantly associated with improved clinical or functioning outcomes. CONCLUSIONS: Results support efficacy of the enhanced emergency department intervention for improving linkage to outpatient mental health treatment but underscore the need for improved community outpatient treatment to prevent suicide, suicide attempts, and poor clinical and functioning outcomes for suicidal youths treated in emergency departments.
