Aim: The aim was to translate the Parental Stressor Scale: Neonatal Intensive Care Unit (PSS: NICU) into the Swedish language and to evaluate the psychometric properties of the Swedish version.
Method: The PSS: NICU was translated into Swedish using the process of forward-backward translation. Thereafter, an internal panel of neonatal nurses (n = 10) assessed face and content validity and a panel of parents (n = 10) assessed content validity. A sample of 95 parents recruited from three different neonatal units completed the PSS: NICU and answered some open-ended questions in which they could comment on language and wording. There were eight new items in the PSS: NICU, compared with the very first version of the instrument. These had not been psychometrically tested previously. In this study, the subscales and total scale were analysed both with and without the new items to determine whether or not to use them. Psychometric properties including internal consistency, Cronbach's alpha (if item deleted) and corrected item total were evaluated.
Result: The result indicates that the Swedish version of PSS: NICU, both with and without the nonvalidated items, has acceptable psychometric properties and can be used in clinical practice in NICUs in Sweden.
Conclusion: In order to meet the psychological needs of parents, healthcare professionals need to identify risk factors in the Neonatal Intensive Care Unit that contribute to stress amongst parents. The Swedish version of the PSS: NICU can be used for this purpose.
