Research Studies


Over the past decade, medical professionals have made significant advances in the medical technology used to care for expectant mothers of multiples, premature infants, and children with ongoing medical or developmental needs. Research has focused on improving care both during and after pregnancy, which has resulted in better health outcomes for expectant mothers and their children.

MOST continues to conduct research studies like those listed below, to help highlight more opportunities to help researchers and practitioners identify areas that might warrant more formal in-depth study and to help keep families and medical professionals up-to-date with recent trends.

MOST is currently seeking new participants for the ongoing research surveys listed below. These studies are open to any MOST Member. If you would like to obtain a survey questionnaire, please contact the MOST office.

Postpartum Depression after Pregnancy Complications

MOST (Mothers of Supertwins) is working with Dr. Amy Przeworski , faculty in the School of Psychology, and  Dr. Judith Maloni a professor of Nursing and Women’s Health at Case Western Reserve University (CWRU) in Cleveland, Ohio, USA  who are conducting an internet based  study about the postpartum mood of women who were hospitalized for a  high risk pregnancy and now, in the postpartum, feel that they are depressed.   The purpose of this study is to determine whether women now have postpartum depression and other moods, their use of the internet to obtain health information   and their desire to seek help using an internet based intervention. The study has been approved by the Institutional Review Board of CWRU  is being conducted using a safe internet site managed by our university.  If you had pregnancy complications, i.e. a/high risk pregnancy and were hospitalized during that time and your baby is now at least 2 months old and you feel you have postnatal depression  you are eligible to participate in the study.  If you are interested in participating, please click on the following link to do so.

MOST Medical Birth Survey

The MOST 'Medical Birth Survey' is a longitudinal study started in 1988. The survey collects data pertaining to socio-demographic status, medical, gynecologic, and obstetric history, pregnancy, perinatal, and neonatal events related to higher-order multiple pregnancies and births. The survey also gathers information regarding breastfeeding and ongoing developmental and medical challenges in multiple birth children. The database of responses currently contains over 1300 participants and over 4000 infants. This survey is one of the most comprehensive and extensive databases on multiple births in the world.

See current statistics from this study:

MOST Divorce and the Multiple Birth Family Survey

The MOST 'Divorce and the Multiple Birth Family' survey was conducted from June 25, 2009 to July 27, 2009. The study was designed to develop baseline statistics about the prevalence of divorce among multiple birth parents, including parents of twins, triplets, quadruplets, and more as well as identify at what point a divorce is most likely to occur during the child rearing years. The survey contained 10 multi-part questions on family background, socioeconomic status, parent and children's age, as well as questions about marital status and divorce.

MOST conducted this survey to help evaluate the level of marital-related support services our organization provides to parents of multiples as well as the overall level of support services offered to single parents of multiples. See current statistics from this study.
