Summary

Background:

* The prevalence of cigarette smoking among individuals with schizophrenia is noticeably higher than in the general population, and smoking cessation attempts frequently are unsuccessful in this population. Little is known about the effects of cigarette/nicotine craving in individuals with schizophrenia. Researchers are interested in learning more about how craving affects people with schizophrenia and developing new ways to treat cravings and improve the effectiveness of smoking cessation therapies and treatments.
* In recent years, virtual reality (VR) has been studied to determine whether it can be used to induce craving by using life-like cue settings. VR cues involving cigarette use, including images of cigarettes and scent cues of tobacco smoke, may be used to elicit craving in smokers. Researchers are interested in learning more about how individuals with schizophrenia respond to specific VR cues and settings.

Objectives:

* To determine the feasibility of using a contextual real-world paradigm using virtual reality involving cigarette smoking in people with schizophrenia.
* To examine if virtual reality cues will elicit craving in smokers with schizophrenia.

Eligibility:

\- Current smokers (five or more cigarettes per day for at least 1 year) between 18 and 45 years of age who have been diagnosed with schizophrenia/schizoaffective disorder.

Design:

* The study will involve three sessions, with an initial screening visit, a test session, and a follow-up session.
* Screening visit: Participants will be screened with a medical and psychiatric history, and will answer questions about smoking history, current smoking habits and craving patterns, and general anxiety levels. This session will also introduce participants to the operation and use of the VR equipment. Participants who are comfortable using the VR system will return within 2 days for the test session.
* Test session: Participants will use the VR equipment to view neutral scenes and scenes that are designed to elicit cravings for cigarettes. After viewing each scene, participants will answer questions about their overall mood, anxiety levels, and any cigarette cravings they may have.
* Follow-up session: Participants will return 1 week after the VR session to answer questions about mood, anxiety levels, and current smoking habits and craving patterns.
