The Pediatric Inventory for Parents - Swedish Translation and Psychometric Testing

The Pediatric Inventory for Parents (PIP) measures parental stress related to caring for a child with an illness. However, no Swedish translation is available.

This study reports a Swedish translation of the PIP and psychometric properties of the instrument.

This is a descriptive/methodological paper. The PIP was translated and culturally adapted to Swedish, and comprehensibility was tested. Data were collected twice from 48 parents of children with different illnesses, and initial psychometric properties of the instrument were examined. The IES-R (Impact of Event Scale-Revised) was used for concurrent validity.

The Swedish version of the PIP demonstrated good correlations with the IES-R, and temporal changes were similar. Endorsement frequencies and test-retest were also satisfactory. When comparing groups of parents, the parents of children with cancer were statistically significantly more distressed, both on total score and for emotional distress and role function. Discriminative validity was demonstrated by comparing parents of children with cancer with parents of children with other diseases.

The Swedish version of the PIP seems to be a valid and reliable instrument. However, as we used relatively small sample, for the future, we suggest further testing with larger samples.

Clinicians and researchers seeking to measure parental distress in chronic illness could use the Swedish version of the PIP.
