Current Studies

 

The DCN Lab is currently enrolling participants aged 9-18 in several studies. All studies take place at Boys Town National Research Hospital's Pacific Street location (132nd St., between Pacific and Dodge).

Testosterone and PTSD Study

In this study, we are trying to understand how changes in testosterone levels impact brain systems involved in emotion regulation. Importantly, testosterone levels change following trauma in some cases, so we are interested in whether the emotion regulation problems in PTSD are linked to changes in testosterone. We are enrolling physically healthy youth aged 14-17 who have experienced psychological trauma and who are experiencing emotional or behavioral problems as a result. A diagnosis of PTSD is not required for participation. This study consists of three visits and will include an assessment by a psychiatrist, completing a series of assessments, a brief interview, and completing some computer tasks, including some tasks in an MRI scanner. Parents/guardians will be asked to complete some questionnaires about their child. Saliva samples will be taken during the MRI visit to assess hormone levels.

Puberty and Emotion Regulation (PER) Study

In this study, we are investigating the role of pubertal development and pubertal hormones (including testosterone, DHEA, and estradiol) on brain systems involved in emotion regulation. As emotion regulation is disrupted in many types of mental illness, we interested in how pubertal development might impact brain regions involved in emotion regulation differently in youth with emotional and behavioral problems. We are enrolling youth aged 9-18. Youth can participate if they are physically healthy. Youth with and without emotional and/or behavioral problems are encouraged to participate. This study consists of two visits and will include completing a series of assessments, and completing some computer tasks, including some tasks in an MRI scanner. Parents/guardians will be asked to complete some questionnaires about their child. Saliva and hair samples will be collected to measure pubertal hormone levels.
