This class points to an administration of the Short Form version of the McGill Pain Questionnaire (SF-MPQ) Assessment Instrument to the Patient. The VA's SCIDO system contains a number of Assessment Events which could conceivably be used in other systems (such as a Behavioral Health system). This class simply serves to link the SF-MPQ assessments in SCIDO to the more general SF-MPQ Assessments modeled in the Assessments package. Logically, neither this class nor the parent SCI_Assessment should exist, but rather the SpinalCordRegistration class should point directly to the relevant SF-MPQ assessments.
