  1. Factor loadings are denoted (𝜆)
  2. Gen =General factor (i.e., impact), PII =Pain interference/intensity factor, PF =Physical function factor. EFA models estimated using minimum residual extraction with an oblimin rotation. Cross-loading values (< .20) are denoted (-) for ease of interpretation
