Revision of a Parental Stress Scale for Use on a Pediatric General Care Unit
Janice B. Agazio and Kathleen M. Buckley
The purpose of this descriptive correlational study was to test and evaluate the
psychometric properties of a revised Parental Stressor Scale: Pediatric Intensive
Care Unit (PSS:PICU) for use on a pediatric general care unit (PSS:GCU). The
sample consisted of 403 parents of hospitalized children in a large military Mid-
Atlantic medical center. Reliability and validity were assessed by examining the
modified scale using factor analysis, Cronbach’s alpha, item analysis, and concurrent
validity. Factor analysis supported the subscales on the PSS:PICU.
Internal consistency of the PSS:GCU produced a Cronbach’s alpha of 0.92 for
the total scale similar to the PSS:PICU scale, with the reliabilities for the subscales
ranging from 0.70 to 0.92. Significant correlations were found between the
total scores of the PSS:GCU and the Family Inventory of Life Events (FILE), a
measure of general life stress. The results of psychometric testing suggest that
the PSS:GCU is a reliable and valid scale to measure parental stress in general
pediatric care units.
