Longitudinal Study of Dyadic Adjustment in a Sample of Spanish Fathers

The objectives of this study were to examine the evolution of fathers’ long-term dyadic adjustment after the birth of a child and to analyze their evolution considering related factors. A total of 113 Spanish fathers with a mean age of 35.72 years (SD = 3.84 years) participated. In general, there was a decline in the dyadic adjustment of the fathers until 6–12 months after childbirth, after which their level of adjustment remained stable until 13–24 months. We observed different patterns when analyzing the evolution by subgroups formed based on these different variables, previous experience of paternity, and anxiety. The intrinsic differences between fathers should also be considered because these differences can influence the way in which men face the parental process as well as the evolution of the quality of their relationship with their partner.
