Research Hart is a researcher at the University of Calgary/Alberta Children's Hospital. Her present research includes co-creating and pilot testing the Attachment and Child Health (ATTACH) Intervention, which explores links between parental reflective function (RF) and parent/child attachment led by
Nicole Letourneau. Hart presented findings on the program at a number International Attachment Related Conferences in New York, London, Miami, Prague; and in Vancouver. The ATTACH Program is funded by Harvard University's Centre for the Developing Child as one of their Frontiers of Innovation projects. In 2019, Hart and Nicole Letourneau launched their ATTACH™ Program online. Hart completed two degrees at the University of Calgary before moving to England to join the Centre for Family Research at the University of Cambridge where she completed her master's degree and Ph.D. programs in Social & Developmental Psychology under supervisor Claire Hughes. Hart worked as a researcher at the University of Cambridge with Ruth Gaunt for several years researching the division of labor in the family and parents’ child care choices before joining the team at the University of Calgary. Hart's past research also consisted of working on a University of Cambridge-based longitudinal project investigating the early origins of children's problem behaviour/self-esteem within a diverse sample, and how social correlates predicts such characteristics, while focusing on children's friendship/sibling/teacher relationships, as well as mother's parenting style and mental states (e.g. self-esteem, depression) and the impact on children's social (problem) behaviour and mental states (e.g. self-esteem) and prosocial behaviour in single/non-single mother households. She has published various peer-reviewed papers, including a top cited article in the 2020–2021 Infant Mental Health Journal on the effect of parental reflective function and has co-edited Development and Adaptation: Seminal Papers on the
Dynamic-Maturational Model of Attachment and Adaptation, published by Waterside Press, and she has also co-authored with another book in publication titled Parenting and Child Development. Hart was trained to administer the PDI at Yale University and the AAI by Howard Steele and Miriam Steele at the New School University New York, as well as Erik Hesse and Mary Main at Berkeley University. Hart is also trained by Howard Steele in RF (PDI), and in Reflective Family Play by Dianne Philip – at The Hincks-Dellcrest Centre Toronto. In addition, Hart trained with Alan Sroufe, and Elizabeth Carlson at the University of Minnesota, and Marinus van IJzendoorn at Cambridge University in the ABCD model of attachment, William Whelan in the MAC attachment measure at University of Virginia, as well as
Patricia Crittenden in the DMM; she is a certified reliable coder in various attachment measures, RF measures, as well as a number of other parent/child interaction measures.
