Discordance between pediatric self-report and parent proxy-report symptom scores and creation of a dyad symptom screening tool (co-SSPedi).

Symptom Screening in Pediatrics Tool (SSPedi) (age 8-18 years) and mini-SSPedi (age 4-7 years) can be used to self-report and proxy-report bothersome symptoms in pediatric patients receiving cancer treatments. There are limitations of sole child self-report or proxy-report. An approach in which children and parents complete symptom reports together may be useful. The aim of our study was to describe discordance between child self-report and parent proxy-report symptom scores, and to determine how these scores compare to an approach in which reporting is performed together (co-SSPedi). Children and parents completed SSPedi or mini-SSPedi separately. Discordant symptoms were shared with respondents and discussed. Next, the dyad completed co-SSPedi together and were asked which approach they preferred. Discordance was evaluated for each symptom and was defined as a difference of at least 2 points on an ordinal scale ranging from 0 (not at all bothered) to 4 (extremely bothered). Of the 48 enrolled dyads (children, median age, 10.8 years; 54.2% male), 41 (85.4%) had discordance in at least one symptom. There was no clear pattern in discordance by age group. When a dyad approach was used, more co-SSPedi scores agreed with the original child self-report scores (59 dyads, 56.2%) compared to original parent proxy-report scores (15 dyads, 14.3%) for discordant symptoms. Forty-three (89.6%) dyads preferred to complete SSPedi together. Future work should evaluate the psychometric properties of co-SSPedi.
