Item Reduction and Scoring of the Pediatric PainSCAN©

Le résumé fourni par la source

OBJECTIVES: The Pediatric PainSCAN© is the first screening tool specifically designed for pediatric neuropathic pain (NP) and complex regional pain syndrome (CRPS). A draft tool (37 items) was developed through a phased approach. This research aimed to reduce the number of items in the tool and to determine the weight of each item (ie, item scores) as it contributes to a probability of a diagnosis of NP or CRPS. METHODS: Survey 1 was administered to patients with NP or CRPS and health care professionals (HCPs). Participants rated the frequency and importance of each item in the draft tool on a 0 to 4 Likert scale; highest rated items were retained. Survey 2 was administered to a separate pool of patients (with NP, CRPS, or other pain conditions) who completed the Pediatric PainSCAN©. A logistic regression model was used to examine the relationship between item responses (yes/no) and patient diagnosis; parameter estimates were used for item scores. RESULTS: Survey 1 was completed by 43 patients (median age 15 y, 77% female) and 74 HCPs. Survey 2 was completed by 221 patients (median age 15 y, 81% female). Nineteen items remained in the final version of the tool; items were rated as important by patients and HCPs. Item scores are summed and converted to a probability score. CONCLUSION: The final set of items in the Pediatric PainSCAN© has been determined and study results provide further evidence of content validity. Additional research is needed to evaluate the tool's reliability, criterion validity, and select a cutoff score.
