The present study examined the longitudinal associations among supportive coparenting
and father engagement during infancy and mother-child attachment at age three within an at-risk sample (N= 1371), using secondary data from Fragile Families and Child Wellbeing (FFCW)
study. Mothers reported on coparenting and father engagement during the one-year phone
interview and mother-child attachment was assessed using the Toddler Attachment Sort-39
(TAS-39) at age three during the three-year in-home interview. Findings suggest that supportive coparenting was significantly associated with higher levels of father engagement and more secure mother-child attachment relationship across three racial/ethnic groups including white, African American, and Hispanic.
