The Pediatric Inventory for Parents: Development of a short-form in fathers of children with type 1 diabetes (T1D)

Background The Pediatric Inventory for Parents (PIP) is a 42-item measure of paediatric parenting stress that results in 84 responses. Although this measure has been extensively validated, the number of items in the instrument may hinder clinical applicability. Methods The current study reports on the development of a short-form of the PIP using data from 344 fathers of children with type 1 diabetes. Recommendations for short-form development as well as item response theory (IRT) were used to construct a 13-item PIP Short-Form that results in 26 responses. Results The retained items were chosen to reflect the content domains of the original form of the PIP and demonstrated acceptable item fit under the partial credit model (PCM; Infit and Outfit indices closest to one and items with thresholds across the span of the latent trait). Conclusions The PIP Short-Form may allow health care professionals to more feasibly assess paediatric parenting stress among parents of children with chronic health conditions. Future studies are needed to validate this new short-form.
