Why are twin studies important for research?

Twins possess special features that enable researchers to better understand the influence of genetics and environment on child development. Identical twins (monozygotic) come from the same egg and share all of their genes. Fraternal twins (dizygotic) come from two seperate eggs and share, on average, half of their genes just like average non-twin siblings. Studying twin pairs allows researchers to compare children who experience very similar environments and who have a fixed rate of genetic similiarity. At the Child Emotion Center, this allows us to examine how genetics and the environment work together to contribute to risk and resilience and give children the capacity to bounce back after trauma, adversity, and stress.

Why is studying children's emotional development important?

Emotional development begins very early, and has a continuing and profound influence on the child's life. By studying children's early emotional development, we are able to identify risk and protective factors for later mental and physical health.

What methods do you use in your research?

Most of our research incorporates survey methodology, where participants (children, parents, teachers) fill out questionnaires related to the topic of interest. Interviews may also be done in the family's home or the child's school, and some interviews may be videotaped for later analysis. Some of our research also includes biological measures, such as collecting cortisol samples from saliva, or a cheek swab to look at genetic influences on behavior. The methods to be used in a particular study are always explained to the participants at the outset and their informed consent is obtained.

How do you maintain confidentiality of the information we share with you about our child?

Keeping your information confidential is very important. All participanting families and children are assigned identification numbers. The numbers replace names on all data as identifiers so that no names are used after the data has been collected. All information stored on the computer is on a secured server that is only accessible to trained research assistants. All physical data (paper surveys, video tapes, etc) are also secured and only available to trained research assistants. We do not release any personal information to any third parties. All published papers report the results of group data, we do not identify any individuals.

Do you screen for childhood psychological disorders or behavioral problems?

Unfortunately we do not have the capability to screen for or diagnose disorders or behavioral problems, nor can we provide therapy or counseling. However, if you are a participant in a study and you are concerned about your child, we can direct you to the appropriate resource.

Who will benefit from the results of these research studies?

Many of our research participants receive a regular newsletter related to the topic of their study. There is also the potential benefit of focusing more on your child's development. Studies like ours are also a benefit to society, by increasing knowledge about early biological and environmental risk and protective factors for later mental and physical health of children.
