First aim is to determine the effect of mother and father kangaroo care on the premature baby's Comfort Behavior level and physiological parameters (respiratory rate, heart rate, oxygen saturation and body temperature). Second aim is to determine the effect of mother and father kangaroo care on Parental Satisfaction and Neonatal Intensive Care Parental Stress level.

The study was a a randomized crossover study with pretest-posttest design. It was carried out in the neonatal intensive care unit of Selçuk University Faculty of Medicine Hospital in Konya province. Study data were collected from 19 mother and 19 father and their premature newborns between February 2023 and August 2023.

In the study, the mother applied kangaroo care to her premature baby for 65 minutes, and after a 24-72 hour washout period, the father applied kangaroo care for 65 minutes. The order of mother and father application was determined randomly.

Data were collected using Physiological Parameters Form, Neonatal Comfort Behavior Scale, Parental Satisfaction Scale and Neonatal Intensive Care Unit Parental Stress Scale.

In the study, physiological parameters and Neonatal Comfort Behavior Scale scores of premature infants and Neonatal Intensive Care Unit Parental Stress Scale and Parental Satisfaction Scale scores of parents were evaluated. Pearson Chi-Square Test, Yates Correction and Fisher's Exact Test were used to compare categorical data according to groups. Two Independent Sample t Test was used to compare normally distributed variables and Mann Whitney U Test was used to compare non-normally distributed variables. Statistical significance level was accepted as p˂0.05.
