Abstract

Background

The experience of having their new-borns admitted to an intensive care unit (NICU) can be extremely distressing. Subsequent risk of post-incident-adjustment difficulties are increased for parents, siblings, and affected families. Patient and next of kin satisfaction surveys provide key indicators of quality in health care. Methodically constructed and validated survey tools are in short supply and parents’ experiences of care in Neonatal Intensive Care Units is under-researched. This paper reports a validation of the Neonatal Satisfaction Survey (NSS-8) in six Norwegian NICUs.

Methods

Parents’ survey returns were collected using the Neonatal Satisfaction Survey (NSS-13). Data quality and psychometric properties were systematically assessed using exploratory factor analysis, tests of internal consistency, reliability, construct, convergent and discriminant validity. Each set of hospital returns were subjected to an apostasy analysis before an overall satisfaction rate was calculated.

Results

The survey sample of 568 parents represents 45% of total eligible population for the period of the study. Missing data accounted for 1,1% of all returns. Attrition analysis shows congruence between sample and total population. Exploratory factor analysis identified eight factors of concern to parents,“Care and Treatment”, “Doctors”, “Visits”, “Information”, “Facilities”, “Parents’ Anxiety”, “Discharge” and “Sibling Visits”. All factors showed satisfactory internal consistency, good reliability (Cronbach’s alpha ranged from 0.70–0.94). For the whole scale of 51 items α 0.95. Convergent validity using Spearman’s rank between the eight factors and question measuring overall satisfaction was significant on all factors. Discriminant validity was established for all factors. Overall satisfaction rates ranged from 86 to 90% while for each of the eight factors measures of satisfaction varied between 64 and 86%.

Conclusion

The NSS-8 questionnaire is a valid and reliable scale for measuring parents’ assessment of quality of care in NICU. Statistical analysis confirms the instrument’s capacity to gauge parents’ experiences of NICU. Further research is indicated to validate the survey questionnaire in other Nordic countries and beyond.
