Sponsor
National Institutes of Health (NIH)
Enrollment
20 participants
Start Date
Jan 1, 2026
Study Type
OBSERVATIONAL
Conditions
Summary
This study is focused on understanding the impact of time spent in nature (relative to an urban control) on stress, neural, and cardiac functioning in people experiencing high levels of stress, depression, and anxiety.
Eligibility
Min Age: 18 YearsMax Age: 25 Years
Inclusion Criteria3
- Meets cut-off for high level of perceived stress on PSS-10 during screening (\>27 total score); Current or past depressive and anxiety disorders, if present on SCID-5 assessment, will be ncluded due to their high prevalence and overlap with perceived stress
- Normal, or corrected to normal, vision (due to the visual nature of the EEG tasks)
- If on psychotropic medication, stable regime for \> 1 month
Exclusion Criteria3
- Major medical conditions with CNS sequelae (e.g., seizure disorders, multiple sclerosis, significant, uncontrolled cardiovascular pathology) Past or present neurological problems (including seizures and head trauma resulting in neurological or cognitive sequelae)
- IQ estimate \<75 on the Test of Premorbid Functioning
- Current or past history of severe mental illness (e.g., bipolar schizophrenia spectrum disorder, or current or past history of substance use disorders
