Personality traits and subjective well-being among fathers of preterm infants in Taiwan: a cross-sectional study.

Objective: This study examined the association of personality traits and paternal/infant background characteristics with subjective well-being (SWB) among fathers of preterm infants. Background: While studies of parental care of preterm infants have focused on mothers or both parents, studies focusing specifically on fathers are relatively rare. In this study, we provide new information on the personality traits and paternal/infant background characteristics and their association with SWB among fathers of preterm infants. Methods: This study used a cross-sectional design. Participants included fathers of preterm infants hospitalised in the neonatal intensive care unit, neonatal intermediate care nursery, or postpartum ward of a medical centre in northern Taiwan within 5 days of birth. The Personality Inventory Scale and Subjective Well-being Scale were administered and background characteristics of fathers and preterm infants were measured. Results: A total of 104 fathers participated, of whom 73.1% showed a moderate level of SWB. Fathers with higher extraversion and openness exhibited higher SWB, while fathers with higher neuroticism exhibited lower SWB. SWB was also predicted by age, infant weight, family structure, and paternal education level. These factors cumulatively accounted for 48% of the variance in SWB. Conclusion: Fathers' SWB was associated with extraversion, openness, neuroticism, age, education, family structure, and infant weight. The personality traits of fathers should be considered when developing plans for family support after following preterm infant birth. In addition to focusing on maternal well-being, programmes to increase paternal well-being would benefit the families of preterm infants.
