Background: Pediatric patients with Turner syndrome (TS) are reported to have a higher incidence of anxiety, depression and social isolation but there is minimal data on self-reported measures. Methods: We utilized the validated PROMIS (Patient Reported Outcomes Measurement Information System) question bank to develop 4-question short forms to assess patient and parent self-reported scores in the domains of depression, anxiety, and peer relationships in our TS cohort. Completed PROMIS short forms from TS patients seen in the multidisciplinary TS clinic between 1/1/2019 and 6/1/2020 were retrospectively analyzed. Clinical data were also abstracted from medical records and correlated with the measures of depression, anxiety, and peer relationships. Descriptive analyses of the T-scores were completed using a non-parametric Wilcoxon rank-sum test and the dyad results were analyzed for agreement between parent and patient reporting. Results: Data from 26 patients (mean age 13y, range 4.6-20.6y) were included in the analysis: 3.9% were clinically referred for depression/anxiety after psychology assessment, 15% had developmental delays and 15% had an individualized education plan. Nearly 77% had short stature (<5%ile), 58% had received growth hormone and 54% were on estrogen therapy. Median scores were not statistically different from population norms for patient (N=22) or parent (N=25) reports in the 3 domains and did not vary by age, estrogen supplementation or stature. Internal reliability of the questionnaires measured by overall Cronbach alpha for each domain were acceptable (0.73-0.93). While parent and patient reported anxiety scores were correlated (R=.452, p=.040.), the depression and peer relationship scores were not correlated. Parent-reported peer relationship scores were negatively correlated with patient-reported anxiety (R=-0.46, p=0.04) and parent reported anxiety (R=-0.43, p=0.04) scores. Parent perceived depression and anxiety measures were also correlated (R=0.77, p< 0.001) as were patient reported scores in these domains (R=0.6, p=0.003). Conclusions: In contrast to existing literature in TS indicating a higher incidence of psychosocial concerns, the patient and parent self-reported scores on depression, anxiety and peer relationship were not statistically different from the population normative data, and parent and patient perceived scores were not correlated in all domains. While the small number of patients in this pilot study may be insufficiently powered to detect a small difference in scores in these domains, the data underscores the need to develop a TS-specific validated psychosocial questionnaire that more adequately assesses the psychosocial concerns in this population.
