Studies actively recruiting participants:


The University of North Texas Department of Psychology is currently seeking participants who are:

  • 18 to 55 years old
  • not currently pregnant or breastfeeding
  • interested in using an investigational gummy product that contains cannabidiol (CBD; non-intoxicating part of the cannabis plant) and other over-the-counter substances (e.g., melatonin, linalool [component of lavender oil], limonene [component of citrus oil], and/or l-theanine [amino acid found in tea])
  • not taking medications or have medical conditions that may interact with the investigational product
  • are able to come to the UNT campus for two brief visits to pick up the products

Interested and eligible individuals may participate in one of two related research studies. The purpose of these studies is to see if a low, moderate dose of CBD (in combination with either melatonin and linalool, or linalool, limonene, and l-theanine) is effective for improving rest, relaxation, and mood. Participation in these studies takes approximately 8-12 hours of your time over the course of 5-8 weeks and includes the following activities:

  • Completion of a baseline survey and virtual interview to determine health status
  • Daily ingestion of the low dose investigational gummy for two weeks
  • Daily completion of brief online surveys for 5-8 weeks
  • Two brief visits to the UNT campus to obtain the products

It is important to remember that participation is voluntary. You will receive compensation for participation.

Sleep and Vaccine Response in Nurses (SAV-RN)
The overarching goal of the current study is to develop a comprehensive model detailing the effects of sleep and its specific facets, as well as other risk factors, on the short-term (1-month) influenza antibody response, as well as its long-term (12-month) degradation.

Treatment of Comorbid Sleep Disorders and PTSD
The primary aim of the study was to determine if providing cognitive-behavioral therapy of insomnia and nightmares (CBTi+n) and Cognitive Processing Therapy of PTSD-Cognitive only version (CPT) results in greater PTSD and sleep symptom reduction than CPT only. The secondary aim was to determine if sequencing CBTi+n before or after CPT results in differential effects on PTSD and sleep symptom reduction.
