The study uses Ice Hockey Summit I and II action plans for SRC reduction among professional and amateur hockey players including magnetic resonance imaging (MRI) and computed tomography for detection of mild traumatic brain injury (mTBI). Also mentioned the importance of SRC reduction for sports events.

This study investigated associations between child temperament and DSM-IV disorders in children. A total of 156 probands (97 boys, 59 girls; mean age = 10.78 years) and 154 randomly selected siblings were assessed using the Junior Temperament and Character Inventory (JTCI) and a structured DSM-IV interview. Subjects were placed in nonoverlapping groups of (1) attention-deficit hyperactivity disorder (ADHD) only, (2) disruptive behavior disorders (DBD) only, (3) DBD plus an affective and/or anxiety disorder (DBD+Int), and (4) controls with no diagnosis. Many JTCI scales were found to differ between diagnostic groups and controls. Regression analyses showed independent associations between low persistence and ADHD-only group membership, high novelty seeking (NS), and the DBD-only group and between high harm avoidance (HA) and DBD+Int group membership. The interaction NS x HA was related to the ADHD-only group. Future research is needed to determine the mechanism of these association.
