Effect of a Play-based Intervention on the Anxiety of Mothers of Premature Babies Admitted to the Neonatal Intensive Care Unit: A Randomized Controlled Clinical Trial

Objective The present study aims to examine the effect of a play-based intervention on the anxiety of mothers of premature babies admitted to the neonatal intensive care unit (NICU). Materials & Methods This is a non-blinded randomized controlled clinical trial. The participants were recruited from among the mothers of premature babies (<37 weeks) admitted to the NICU of Hazrat-e Ali Asghar Hospital and divided into two groups of intervention (n=20) and control (n=20) using the block randomization method. They were 20-35 years old with at least a high school diploma. Their babies had stable physiological conditions with no physical disorders or specific diseases. The anxiety of mothers was measured by Spielberger’s State-Trait anxiety inventory (STAI) before study and two days after discharge. The intervention group received the play-based program for their babies at least once a day, for at least 5 days until discharge. The control group received routine hospital care. Results Independent t-test results showed no significant difference in the scores of STAI and its domains between the two groups before and after the intervention. However, mean difference of pre- and post-scores of total STAI and state anxiety domain was significant in two groups (P<0.05), but it was not significant in terms of trait anxiety (P>0.05). The ANCOVA results showed that the effect size of intervention on state anxiety (P=0.001) and total anxiety score (P=0.004) was 27% and 20%, respectively. Conclusion The play-based intervention, can reduce the anxiety of mothers of premature babies admitted to the NICU and consequently affect the growth of children and mental health of family and society.
