Schizophrenia Clinical Trial
Official title:
Screening Protocol for the Evaluation of Research Participants
The Screening Protocol is a system devised to evaluate potential research participants for National Institute on Drug Abuse/Maryland Psychiatric Research Center (NIDA/MPRC) studies.
The MPRC/NIDA collaborative research program attempts to: elucidate the nature of serious
mental illnesses, drug abuse and addiction; determine the potential use of new therapies,
both pharmacological and psychosocial; and decipher the long-term effects of drugs of abuse
on the development, maturation, function, and structure of the brain and other organ systems.
In support of this work, the scientific goal of this screening protocol is to assess
potential research participants' eligibility for research studies. Screening will include
medical and psychological tests and procedures. The data collected during screening are a
unique and valuable source of information that aids in the research mission. Therefore, a
secondary goal of this protocol is to obtain data that characterizes the population of
subjects contacting NIDA about research participation and to analyze data so obtained, such
as that on the prevalence and consequences of HIV/AIDS, viral hepatitis, and related diseases
and issues of selection and sample bias in clinical research.
The screening process will be done in two stages, a telephone interview and an in-person
evaluation. The telephone interview will last approximately 20 minutes and be conducted
solely via the NIDA call center. Answers provided during the phone interview will indicate
whether a caller is eligible for in-person screening. Those who appear eligible will be given
an appointment at either NIDA or MPRC. This protocol pertains only to the in-person
participants at MPRC. Written informed consent will be obtained when the person arrives. The
screening process can involve up to 5 visits to MPRC.
