Juvenile Anxiety Study (JAS)

New Study opportunity for juvenile twins…

Researchers at VCU’s Department of Psychiatry are working with the National Institutes of Health in hopes of learning more about how certain conditions, such as anxiety and depression develop.

Participants the study will need include:

  • Generally healthy Caucasian MATR twin pairs (9 through 13 years old)
  • One or both parents (or legal guardians) of the twin pair

Study participation involves:

  • Parent/Guardian completing a phone call (approximately 20 minutes) with a MATR Research Interviewer. This phone call will include some questions to collect basic study data and ask permission for the study to contact the parent/guardian directly.
  • Both members of the twin pair and at least one of the parents/guardians completing an appointment at one of the Study Research Centers(at VCU in Richmond, VA or the National Institutes of Health (NIH) in Bethesda, MD) to complete study tasks and questionnaires.
  • Optional online survey to be completed by parents.
  • Financial compensation will be provided by the study.

If interested:

Contact the Mid-Atlantic Twin Registry (MATR) and let us know that you want to learn more about the Juvenile Anxiety (JAS) Study. Please let us know your full name, your twins’ full names, their date of birth, and the best phone number to reach you. You can reach us at:

Adolescent and Young Adult Twins

New Study opportunity for adolescent and young adult twins...

Researchers at VCU’s Department of Psychiatry are working on a study funded by the National Institutes of Health in hopes of learning more about how certain conditions, such as anxiety and depression develop.

Participants the study will need include:

  • Generally healthy MATR twin pairs (Caucasians, 16 through 19 years old)
  • Twin pairs, including the young adult twins, need to be living full-time at home with their parent(s)
  • One or both parents (or legal guardians) of the twin pair

Study participation involves:

  • Parent/Guardian of adolescent twins or the adult twins (18+) completing a phone call (approximately 20 minutes) with a MATR Interviewer. This phone call will include some questions to collect basic study data and ask permission for the study to contact the parent or young adult twins directly.
  • Both members of the twin pair (for adolescent twins this includes at least one of the parents/guardians) completing an appointment at VCU in Richmond, VA to complete study tasks and questionnaires.
  • Optional online survey to be completed by parents.

If interested:

Contact the Mid-Atlantic Twin Registry (MATR) and let us know that you want to learn more about the Adolescent & Young Adult Twin Study (AYATS). Please let us know the full names and DOB of the twin pair. Parents, please provide your full name as well. You can reach us at:

Study of Rheumatoid Arthritis (RA): Recruitment Continues!

Dr. Jose U. Scher & colleagues at New York University's Hospital for Joint Diseases continue their collaboration with the MATR to help learn more about rheumatoid arthritis (RA).

Who's needed? Identical Adult Twin Pairs — where one or both members of the pair have rheumatoid arthritis.

Why is this study needed? This is not a treatment study but rather one that seeks to collect important data and samples that will help improve scientists' understanding of RA with the goal of advancing treatment options and perhaps even one day preventing RA.

Interested in learning more? Contact the MATR at 1-800-URA-TWIN (1-800-872-8946) and leave us a message with your name and best way to contact you or email us at matr@vcu.edu. The MATR will tell you more about the study and then you decide whether you want to be contacted by the study staff. It is okay to decide you don't want to participate; the study staff will not be given any information about you without your permission.

Dr. Scher and his team wish to thank those twins that have already participated or contacted him about the study and look forward to continuing their collaboration with the MATR Community!

MATR Survey for Adults

The MATR would like to invite all registered adult twins to participate in our new on-line MATR Survey, which aims to collect some basic health and behavioral data from our participants. The survey takes 30-45 minutes to complete and you can skip any questions you don't want to answer. The answers to the survey questions will be kept by the MATR and will help us determine if you are eligible to participate in future studies looking into specific conditions or behaviors. If you are interested in participating, please fill out the form below and we will send you an invitation.
