A TWIN STUDY OF HORMONES AND BEHAVIOR ACROSS THE MENSTRUAL CYCLE

This study investigates systematic changes in ovarian hormones (e.g., estrogen and progesterone) and behavior across the menstrual cycle in identical and fraternal female twins between the ages of 15-25 years. The aim of this study is to examine whether associations between ovarian hormones, mood, and behavior are influenced by genes. We are currently focusing our recruitment on twin pairs in which one or both co-twins are taking hormonal contraceptives. This study is directed by Dr. Kelly Klump.

Hormones, Behavior And Brain Activity Across The Menstrual Cycle

This study investigates systematic changes in ovarian hormones (e.g., estrogen and progesterone), behavior, and brain activity across the menstrual cycle in identical and fraternal female twins between the ages of 16-30 years. The aim of the study is to explore how mood and behavior may be influenced by the activation of neural systems during different phases of the menstrual cycle, and how these associations may be influenced by genes. This study is directed by Dr. Kelly Klump and Dr. Jason Moser.

Michigan Twin Neurogenetics Study (MTwiNS)

The goal of MTwiNS (Michigan Twin Neurogenetics Study) is to better understand brain and behavior development in a sample of twins. Specifically, using a twin design, we are collaborating with researchers at the University of Michigan to examine how differences in behavior emerge at the level of the brain. MTwiNS builds on The Twin Study of Behavioral and Emotional Development in Children (TBED-C). We are currently following up with families that previously participated in the TBED-C. These families include twins that are age 7 – 15 years old. During their visit, families engage in an MRI session, clinical interviews, family interactions, and self-reports from the child and parent. This study is ongoing and funded by the Avielle Foundation, the University of Michigan, and MSU.

Michigan Twins Project

The Michigan Twins Project (MTP) is a survey of all twins in Michigan ages 3-29 (for twins ages 30-55, please see the Children of Twins Project). Twin families are recruited for the MTP through birth records, in collaboration with the Michigan Department of Health and Human Services. The MTP includes twins who are living and/or were born in Michigan, as well as twins from surrounding states who are interested in our research. Families complete and return a brief questionnaire, either online or by mailing in a paper form, that assesses family composition and health status. Families with twins younger than the age of 18 complete one questionnaire for the family, while adult twins each complete a questionnaire for themselves. Participants are sent a gift card to thank them for their participation and are given the opportunity to be contacted about future twin studies offering additional financial compensation. This study is directed by Drs. S. Alexandra Burt and Kelly Klump.

Children of Twins Project

Funded by a grant from the MSU Foundation, the Children of Twins Project (COT) is a survey completed by adult twins in Michigan ages 30-55. Twins are recruited for the COT through birth records, in collaboration with the Michigan Department of Health and Human Services. The COT includes twins who are living and/or were born in Michigan, as well as twins from surrounding states who are interested in our research. To participate, each adult twin completes and returns a brief questionnaire, either online or by mailing in a paper form, that assesses family composition and health status of the adult twins and their children. Participants are sent a gift card to thank them for their participation and are given the opportunity to be contacted about future twin studies offering additional financial compensation. This study is directed by Drs. S. Alexandra Burt and Kelly Klump.

Michigan Twins Project Follow-Up Study

The Michigan Twins Project Follow-Up Study seeks updated, developmentally appropriate information for twins and their families who previously participated in the Michigan Twins Project (MTP), now that the twins are older. The examination of developmental differences is a key aspect of the MSUTR, and we hope to conduct follow-ups with many of our twin families. We are currently recruiting families who previously completed the MTP questionnaire for 3-7 year-olds and whose twins are now at least 8 years old. Families who participate in the Michigan Twins Project Follow-Up Study are sent a gift card to thank them for their continued participation. This study is directed by Drs. S. Alexandra Burt and Kelly Klump.

Healthy Twins Study

We are collecting information on families that have been recruited for the Michigan Twins Project, but have yet to participate. To make sure our results are as accurate as possible, this study examines similarities between these families and those that have already participated in the Michigan Twins Project. Families who participate in the Healthy Twins Study are sent a gift card to thank them for their participation and are given the opportunity to be contacted about future twin studies offering additional financial compensation. This study is directed by Drs. S. Alexandra Burt and Kelly Klump.

Twins & Siblings Study

This study investigates the influence of prenatal gene expression on acting-out behaviors in twins ages 3-5 years and their non-twin siblings. Study participation entails at least one parent filling out a series of questionnaires on the twins and their siblings. In addition, given the parents’ permission, we will access the children's dried blood spot samples, which were collected at the time of their birth as part of the State of Michigan’s Newborn Screening Program. The blood spot samples will be used to examine genetic expression at the time of the children’s birth and how that relates to their behaviors and moods today. Families who participate in the Twins & Siblings Study receive a $50 Meijer gift card for their time. This study is directed by Dr. S. Alexandra Burt.

If you would like information on how to participate in this study, please contact us at (517) 355-6878 or burtlab@msu.edu.
