Risk Stratification in Children With Concussion

Change in concussion symptom burden and severity as measured by the Post Concussion Symptom Scale (PCSS)

The PCSS consists of 22 questions that relate to post-concussive symptoms. Survey-takers are asked to rate each symptom according to a 7-point Likert scale ranging from 0-6. Higher scores indicate a higher severity of post-concussive symptoms. The greatest possible score is 132 and the lowest possible score is 0.

Change in post concussion fatigue burden and severity as measured by the PROMIS Pediatric Item Bank v2.0 - Fatigue

The PROMIS Pediatric Fatigue item bank consists of 25 self-report items which measure fatigue symptoms in children aged 8-17 years. Items are ranked on a 5-point likert scale ranging from 1 (Never) to 5 (Almost Always). Raw scores are converted to T-scores using scoring tables. A T-score of 50 is the average for the United States general population. A higher PROMIS T-score represents more of the concept being measured. For negatively-worded concepts like fatigue, a T-score of 60 is one SD worse greater degree of fatigue than average. By comparison, a fatigue T-score of 40 is one SD better lesser degree of fatigue than average.

Change in degree of involvement with one's peers in usual social roles, activities and responsibilities as measured by the Neuro-QoL Item Bank v1.0 - Pediatric Social Relations - Interaction with Peers

This instrument consists of 8 self-report items focused on patient-reported involvement with peers in usual social roles, activities, and responsibilities. Items are rated on a 5-point likert scale ranging from 1 (Never Interacting) to 5 (Always Interacting). Raw scores are converted to T-scores using conversion tables, with a T-score of 50 as the mean. A higher Neuro-QoL T-score represents more of the concept being measured. For positively-worded concepts this measure, a T-score of 40 is one SD worse less interaction with peers than average. By comparison, a fatigue T-score of 60 is one SD better more interaction with peers than average.

Change in perceived difficulties in everyday cognitive abilities such as memory, attention, concentration, processing speed and organization skill as measured by the Neuro-QoL Item Bank v2.0 - Pediatric Cognitive Function

This instrument consists of 8 self-report items focused on patient-reported difficulties with basic cognitive abilities such as memory, attention, concentration, processing speed, and organization skill. Items are rated on a 5-point likert scale ranging from 1 (Not at all) to 5 (Very much). Raw scores are converted to T-scores using conversion tables, with a T-score of 50 as the mean. A higher Neuro-QoL T-score represents more of the concept being measured. For cognitive function, a T-score of 40 is one SD less difficulty than average. By comparison, a T-score of 60 is one SD more difficulty than average .
