Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Background: * Drugs of abuse have effects on mood, behavior, thinking, and decision making that may encourage people to continue using them and make it difficult for them to stop. Researchers who study these effects are interested in developing new tests to evaluate how drugs and drug use affect different areas of the brain. * Magnetic resonance imaging (MRI) scans allow researchers to study brain activity and changes to brain function. When specific psychological tests are performed during functional MRI (fMRI) scans, researchers can examine the effects of drug use on the brain. By developing and testing new procedures for fMRI studies, more information can be obtained on brain function and activity in drug-using and non-drug-using individuals, and this information can help develop new treatments and therapies for substance abuse. Objectives: \- To develop, assess and refine of cognitive and affective tasks and determination of their practical feasibility and efficacy for both MRI and non-MRI application. Eligibility: * Healthy volunteers between 18 and 65 years of age who are willing to undergo MRI scanning. * Both drug-using and non-drug-using individuals will be selected for this study. Design: * Before the start of the study, participants may complete as assessment of medical and psychological history, and provide information about past or current drug use. Researchers will introduce the tasks to be performed and may have participants practice the tasks. * During the study, participants will be asked to do one or more tasks selected by the researchers. The tasks may be performed on a computer in an MRI machine, and may involve receiving rewards (such as money or sips of juice) for actions, memory and reaction-time tests, or other tests that involve responding to instructions on the screen. * Participants will receive compensation for their participation in the study, including hourly compensation for individual visits.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:18 Years to 65 Years

Sexes Eligible for Study:ALL

Accepts Healthy Volunteers:Yes

Standard Ages:ADULT, OLDER_ADULT

Inclusion Criteria	Exclusion Criteria
1. Between the ages of 18-65. 2. All subjects must be able to provide informed consent/assent. 3. Additional criteria for specific populations: 1. 379-bench-smoker/vaper: regular smoker of tobacco cigarettes or nicotine vaper with a urine cotinine level corresponding to nicotine user status for the specific test being used (typically corresponding to a urine cotinine above about 200 ng/ml) and have been smoking or vaping consistently for at least one year (excluding quit attempts) 2. 379-bench-user: DSM-V substance use disorder on a substance other than nicotine.	1. History of neurologic injury including but not limited to CVA, CNS tumor, or head trauma with persistent sequelae. Assessment tool: pre-screen survey and medical history. 2. Current use of psychoactive medications likely to affect the performance of the task under consideration, unless required for the psychiatric disorder for which participants in the 379-user and 379-other-psych-diagnosis subcategories are being treated. Assessment tool: pre-screen survey, medical history. Rationale: certain psychoactive medications may alter performance on the range of tasks to be piloted under this protocol. 3. Cognitive impairment. Assessment tool: self report of extended placement in special education classes for learning problems, history of specific learning disability or mental retardation. Rationale: Cognitive impairment is likely to impair performance on the range of tasks to be piloted under this protocol and may impair ability to tolerate the procedures. 4. Current major mood, anxiety or psychotic disorder with symptoms severe enough to impair ability to participate (unless task is being evaluated in a specific clinical population). Assessment tool: self report, medical history. Rationale: Current major mood or psychotic disorders with poorly controlled symptoms may impair performance on the range of tasks to be piloted under this protocol and may impair ability to tolerate the procedures. 5. Non-English speaking. Assessment tool(s): self-report. Rationale: To include non-English speakers, we would have to translate the consent and other study documents and hire and train bilingual staff, which would require resources that we do not have and could not justify given the small sample size for each experiment. Additionally, the data integrity of some of the cognitive tasks and standardized questionnaires used in this study would be compromised as they have only been validated in English. Most importantly, ongoing communication regarding safety procedures is necessary when participants are undergoing study procedures. The inability to effectively communicate safety procedures in a language other than English could compromise the safety of non-English speaking participants.
