L., Terrell, S., Tinajero, R., Shakiba, N., Monk, C., Shakib, J., Buchi, K. F., & Conradt, E. (2019). Intergenerational transmission of emotion dysregulation part II: Developmental origins of newborn neurobehavior. *Development and Psychopathology.* doi:10.1017/S0954579419000440 This manuscript is the second in a series of two manuscripts (Lin et al., 2019). In the current study, we investigated whether neurobehavioral markers of risk for emotion dysregulation were evident among newborns, as well as whether the identified markers associated with prenatal exposure to maternal emotion dysregulation. This project contains the pre-registration, data, and analysis code for the study described in our paper. We analyzed the data in SPSS v25 and MPlus v8.0. To run the code you will need access to each of these programs. Certain variables have been omitted from the SPSS file ("xxx.sav") to protect anonymity of our participants and their families.
