A randomized controlled trial of cognitive-behavior therapy plus bright light therapy for adolescent delayed sleep phase disorder.

Objective: To evaluate cognitive-behavior therapy plus bright light therapy (CBT plus BLT) for adolescents diagnosed with delayed sleep phase disorder (DSPD).

Design: Randomized controlled trial of CBT plus BLT vs. waitlist (WL) control with comparisons at pre- and post-treatment.

Predictors of posttraumatic stress in children following injury: The influence of appraisals, heart rate, and morphine use.

Prospective studies of posttraumatic stress disorder (PTSD) in children that investigate simultaneously both cognitive and biological or psychophysiological predictors are rare. The present research reports on the impact of cognitive factors (trauma-related appraisals) and biological indicators (heart rate, morphine use) in predicting PTSD and depression symptoms following single-incident trauma. Children and adolescents (N=48) were assessed within 4 weeks of an injury that led to hospital treatment and followed up 6-months later.
