The Effect of Supportive Nursing Interventions on Reducing Stress Levels of Mothers of Infants in the Neonatal Intensive Care Unit: A Randomized Controlled Trial

Abstract

The purpose of this study was to determine the effects of supportive interventions on the stress levels of mothers with infants hospitalized in the Neonatal Intensive Care Unit (NICU). This study was a prospective, pre-and post-test randomized controlled trial. The research was completed with 85 mothers in two groups of 45 subjects and 40 controls selected at random. Data collection used the Parental Stressor Scale: Neonatal Intensive Care Unit (PSS:NICU), NICU Parent Belief Scale (NICU:PBS), State-Trait Anxiety Inventory (STAI TX-2) and saliva cortisol analysis. There were statistically significant differences in favor of the experiment group for the PSS:NICU images and sounds subscale and PBS total points after supportive interventions (p < .05). Supportive nursing interventions were effective in reducing stress related to the intensive care environment, anxiety levels and saliva cortisol levels and increasing parental belief among mothers.
