British Columbia Postconcussion Symptom Inventory
The British Columbia Postconcussion Symptom Inventory (BC-PSI), is a 16 item self-report inventory designed to measure both the frequency, and intensity of the ICD-10 criteria for Post concussion syndrome, which is a common occurrence in cases of mild traumatic brain injury. The (BC-PSI) asks the respondent to rate the severity of 13 symptoms rated on a six-point Likert-type rating scale that measures the frequency and intensity of each symptom in the past two weeks. Frequency ratings range from 0 = “not at all” to 5 = “constantly”. Intensity ratings range from 0 = “not at all” to 5 = “very severe problem”. The two ratings are multiplied (how often × how bad) to create a single score for each item. These product-based scores are then converted to item scores that reflect both the frequency and intensity of symptom endorsement (range = 0–4). Item product scores convert to item total scores: 0–1 = 0, 2–3 = 1, 4–6 = 2, 8–12 = 3, and 15+ = 4. Item scores of 3> reflect moderate to severe symptom endorsement, Item scores from 1 - 2 reflect mild endorsement of the symptom BC-PSI items Headaches Dizziness/light-headed Nausea/feeling sick Fatigue Extra sensitive to noises Irritable
