In the present study the relationships between dimensions of parental identity (commitment, in-depth exploration, reconsideration of commitment), romantic adult attachment (anxiety and avoidance in a relationship) and perfectionism (self-oriented, other-oriented, and socially prescribed) were analyzed. 206 mothers aged 22 to 40 participated in the study (M = 33.33, SD = 3.68). The results revealed that both adult attachment and perfectionism correlate with parental identity. In particular, attachment-related anxiety and other-oriented perfectionism can be treated as independent, specific predictors of an increased crisis of parental identity, manifested in low identification with the role of the parent and in regret of becoming one. The article discusses theoretical and practical implications of the research and suggestions for further studies.
