Study linked the Patient-Reported Outcomes Measurement Information System® (PROMIS) pediatric and adult measures for emotional distress using data from participants with diverse health conditions and disabilities. Analyses were conducted and compared in two separate samples to confirm the stability of results. One sample included 874 individuals aged 14–20 years with special health care needs and who require health services. The other sample included 641 individuals aged 14–25 years who have a physical or cognitive disability. All participants completed both PROMIS pediatric and adult measures, which included the following emotional distress domains: depression, anxiety, and anger. Item response theory-based scores were linked using the linear approximation to calibrated projection. Results showed that the estimated latent-variable correlation between pediatric and adult PROMIS measures ranged from 0.87 to 0.94. Regression coefficients β0 (intercept) and β1 (slope), and mean squared error are provided to transform scores from the pediatric to the adult measures, and vice versa. This study used a relatively new linking method, calibrated projection, to link PROMIS pediatric and adult measure scores, thus expanding the use of PROMIS measures to research that includes both populations.
