The predictive roles of parental stress and intolerance of uncertainty on psychological well-being of parents with a newborn in neonatal intensive care unit: a hierarchical linear regression analysis.

Background: Hospitalization of newborns in neonatal intensive care units (NICU) exposes parents to considerable stress. This study aimed to determine the predictive role of parental stress and intolerance of uncertainty on the psychological well-being of parents with a newborn in NICU using hierarchical linear regression analysis.

Methods: This cross-sectional study included 130 parents of newborns hospitalized in the NICU. Data were collected using Parental Stress Scale, Intolerance of Uncertainty Scale, and Psychological Wellbeing Scale. The data were analyzed in SPSS v.26 using hierarchical linear regression analysis.

Results: The mean scores of the parents' psychological well-being, parental stress, and intolerance of uncertainty were 79.08 (SD = 11.70), 63.06 (SD = 26.71), and 75.38 (SD = 19.40), respectively. The result of the hierarchical linear regression analysis revealed that, in step 1, academic education had a significant proportion of the variance of parents' psychological well-being (β = 0.26, P = 0.005). In step 2, it was shown that academic education (β=-0.25, P = 0.006) and parental stress (β=-0.25, P = 0.006) had a significant proportion of the variance of parents' psychological well-being. According to step 2, education levels, parental stress, and intolerance of uncertainty explained 22% of the changes in parents' psychological well-being.

Conclusion: There was a significant association between the parents' psychological well-being and education levels, intolerance of uncertainty, and parental stress. Academic education and parental stress were the predictors of parents' psychological well-being. Based on these findings, early detection of parents' education and stress are important for their psychological well-being.
