This study is called Cognitive Strategies in Early Psychosis 1, or COSTEP 1 for short. The purpose of this research is to learn more about decision making in psychosis spectrum disorders.
In this study, we will ask adults who do not have psychosis to take a single dose of an FDA-approved medication called modafinil. Modafinil is a medication that is used to treat narcolepsy, shift sleep disorder, and obstructive sleep apnea. In this study, modafinil is considered an experimental agent, meaning we are not using it in the same way that the FDA has approved it for.
We're interested to learn how this agent changes how people complete brain games that measure decision making and how it changes brain activity. We measure brain activity through electroencephalography, or EEG. EEG uses a cap with sensors to measure your brain waves. This will improve our understanding of psychosis and help people in the future.
This study involves three study appointments, and a total time commitment of about 6.75-7.5 hours.
Intake and Clinical Research Appointment:
At the first appointment, we would talk about the study in more detail and go through the consent form to see if you are interested in participating. If you agree to participate, we would ask you questions about your life experiences, including your mental health, and have you complete some brain games. This appointment would take about 1.5 hours after signing the consent form.
Health Screening Appointment:
Then, we will ask you to come to an in-person appointment about a week later. The appointment will take place at the MHealth Fairview Riverside Campus in Minneapolis. The appointment will include a blood draw and urine test to make sure it is safe for you to take modafinil and brain games on an iPad. This appointment will last about 45 minutes.
EEG and Study Agent Appointment:
After the Health Screening Appointment, you will come in for your final appointment. First, we will finish the screening measures, which include a breathalyzer and providing a urine sample to test for the presence of alcohol and any illicit drugs, such as cocaine. For your safety, if either test comes back positive for any substance, we would need to reschedule this appointment for another time. If there is a physical possibility that you could be pregnant, we will also conduct a urine pregnancy test.
Then, we will place an EEG cap on your head, which will measure your brain waves. We will ask you to complete brain games on a computer. Next, you will take a single dose of modafinil. We will wait an hour for the drug to fully metabolize. We would take a break and provide you with lunch. After the hour wait is done, you will complete the same brain games you did earlier. This appointment will last about 5 hours.
Check-in Phone Call:
The day after this appointment, study staff will call you to see how you are feeling after taking the medication. This call will take about 10 minutes.
