THE RELATIONSHIP BETWEEN MENTAL HEALTH HISTORY AND SYMPTOMS, SEX, AND RECOVERY TIME IN A CONCUSSED PEDIATRIC POPULATION

BACKGROUND: The Generalized Anxiety Disorder scale (GAD-7) and Patient Health Questionnaire (PHQ-9) are mental health screening instruments that assess symptoms of depression and anxiety. Studies of patients with concussion suggest that history of mental illness is associated with prolonged recovery; however, little research has examined the value of these tools in a concussed pediatric population (Iverson et al., 2017). HYPOTHESIS/PURPOSE: The purpose of this study was to explore the relation between anxiety and depression symptoms, mental illness history, sex, and time to recover in a concussed pediatric population. We hypothesized that mental health symptoms and history, and female sex would predict longer recoveries in the pediatric population. METHODS: IRB-approved retrospective chart review was used for data collection. Demographics, self-reported mental health history, GAD-7, and PHQ-9 scores were acquired for 250 adolescents ages 12-18 (45.2% female) who presented to an outpatient concussion clinic for their initial visit. Days to recover was imputed for all patients who had been discharged by clinic physicians based on international return to play standards. RESULTS: Mann-Whitney U tests were used for analysis of this nonnormally distributed data. Males were found to recover more quickly than females (female median = 15 days, IQR 7-27; male median = 12 days, IQR 6-23; p=.013). No significant differences were observed in days to clearance based on reported history of mental health disorder (p=.066). Individuals who scored above cutoff (see Kroenke et al., 2001; Spitzer et al., 2006) on the GAD-7 (below cutoff median = 12.00 days; above cutoff median = 21.00 days) and PHQ-9 (below cutoff median = 23.5 days; above cutoff median = 57.00 days) required longer recovery times (p <.001). CONCLUSION: We found longer recovery times in females versus males, and in those whose scores fell above cutoff for the PHQ-9 and GAD-7 at their initial clinic visit. Although a trend existed, there were no significant differences in recovery time for those who reported a mental health history compared to those who did not. Results suggest that the GAD-7 and PHQ-9 may be useful screening measures in a concussion clinic and may provide additional insight into potential recovery times for pediatric patients.
