Post-concussion syndrome

chronic brain syndromepost concussion syndromepost-concussion symptoms
The RPQ is used to determine the presence and severity of post-concussion syndrome (PCS), a set of somatic, cognitive, and emotional symptoms following traumatic brain injury that may persist anywhere from a week, to months, or even more than six months.
A test called the Rivermead Postconcussion Symptoms Questionnaire, a set of questions that measure the severity of 16 different post-concussion symptoms, can be self-administered or administered by an interviewer.

In each case, the symptom is compared with how severe it was before the injury occurred (premorbid).

The questionnaire can feasibly be used as any other neuropsychological test for assessment of concussions would, including following MTBI following accidents or sports-related injury.

Chronic pain

The questionnaire can also be used for the assessment of conditions that show symptoms similar to PCS, such as chronic pain.

Cognition

The questionnaire includes a selection of cognitive, somatic, and emotional symptoms associated with post-concussion syndrome.

Emotion

The questionnaire includes a selection of cognitive, somatic, and emotional symptoms associated with post-concussion syndrome.

Depression (mood)

For example, depression may contribute to the development or severity of PCS, whether triggered by a physical injury or not.

Factor analysis

factorfactorsfactor analyses
The RPQ has been shown to fit best to a two-factor model of the syndrome (see Factor analysis), with somatic and emotional symptoms collapsed into one factor and cognitive symptoms in another.

Covariance

covariantcovariationcovary
This is due to high covariance in reported symptom severity scores between the symptoms classified as "somatic" and "emotional".

Rasch model

RPQ-3 and RPQ-13 symptoms (not corresponding to somatic and emotional scales) are also scored separately, as they have shown to fit poorly to the Rasch model when scored on a single scale.

Repeatability

In doing this, each scale forms a unidimensional construct, demonstrating good test-retest reliability.

Predictive value of tests

Further studies are necessary to establish any predictive value of the RPQ, however.

Recreational drug use

Recreational drug use, for instance, can often result in symptoms similar to those associated with PCS, making it difficult to determine the severity of a head injury if the victim is a habitual drug user.
