Abstract
Maturity to parenthood is essential for taking on parental roles but remains an understudied issue. Still, close relations between maturity and personality dimensions are commonly emphasized. Thus, conducting research on maturity in context of personality seems a valuable research direction. The present research consists of two studies, focusing on the development and validation of Maturity to Parenthood Scale (MPS), in relation to personality, emotional regulation, coping with challenges, and intimate relationship satisfaction. In both studies, childless adults aged 20-35 years took part: (1) 718 participants (M(age) = 25.49; SD = 2.89; 479 women), (2) 150 participants (M(age) = 23.69; SD = 3.15; 104 women). All the participants had been in an intimate relationship for at least six months at the time of the study, the majority declared their willingness to have children in the future, had higher education, and were professionally active. The results showed that MPS is a reliable, valid measure comprising the following three subscales: valence, behavioral, and cognitive-emotional maturity to parenthood. The findings also confirmed the importance of broad- and narrow-band individual differences and contextual factors for maturity. MPS may be used in psychoeducation, supporting the transition to biological or adoptive/foster parenthood, as well as in medical and psychological care.
