Patient Reported Outcome Measures (PROMs) are useful for understanding the health needs and outcomes of the general public. We aim to develop a burn-specific metric-Adult Burn Outcome Questionnaire (ABOQ)-that is brief and can be administered electronically to all burn survivors over the age of 18. The 14-item ABOQ was developed from the already validated Young Adult Burn Outcome Questionnaire (YABOQ) long form. The ABOQ questionnaire, along with Patient-Reported Outcomes Measurement System-10 (PROMIS-10), was administered to 120 outpatient burn survivors at three hospitals. Clinical validity of the ABOQ was measured by testing associations between ABOQ items and burn size, the PROMIS-10 generic items and composite scales using correlational analysis including multivariate canonical analysis. Nine out of 14 ABOQ items were significantly correlated with burn size (correlations ranging from -0.25 to -0.46, P < .01). The canonical correlation between ABOQ and burn size was 0.68 (P = .0002). The overall canonical correlation between two instruments was also significant (P < .0001). At the item level, at least 25% of the variation in each of the five ABOQ items could be explained by PROMIS-10 items and composite scores, while six other items could only be accounted for by less than 15% of the variation. ABOQ short form assessment can be used to efficiently measure burn outcomes across a range of relevant clinical domains with credible validity. A large proportion of the variation in ABOQ scores was not accounted for by PROMIS-10, suggesting that ABOQ provided additional health-related information specifically for the burn population beyond the generic instrument.
