Profile of brief symptom inventory-18 (BSI-18) scores in collegiate athletes: A CARE Consortium study.

: The goal of this study was to characterize normative scores for the Brief Symptom Inventory (BSI-18) in collegiate athletes to inform decision making about the need for psychological health services in this group. : Collegiate student-athletes ( = 20,034) from 25 universities completed the BSI-18 at their preseason baseline assessment. A subgroup ( = 5,387) underwent multiple baseline assessments. Global Severity Index (GSI) scores were compared to community norms and across multiple timepoints. : Collegiate athletes reported significantly lower GSI scores than published community norms (<.001). Published GSI threshold scores for "caseness", identified only 2 per 100 athletes (≥ the 98th percentile) as needing further evaluation. Using a GSI score ≥ than the cohort's 90th percentile, 11.4 per 100 athletes would merit additional evaluation. These individuals were more likely to report a history of psychiatric diagnosis (Odds ratio [95% CI] 2.745 [2.480, 3.039]), as well as ≥ 2 prior concussions (<.001). GSI scores were not highly correlated across timepoints. Suicidal ideation was rare ( = 230; 1.15%). : For collegiate student-athletes, published BSI-18 threshold scores identify only extreme outliers who might benefit from additional behavioral health evaluation. Alternatively, use of threshold scores ≥ the 90th percentile identifies a more realistic 11.4% of the population, with higher likelihood of prior concussion and/or psychiatric disorders.
