  1. Cronbach's alpha. Should be > 0.70 to be statistically reliable
  2. Unidimensionality tested using Martin-Löf-Test. Non-significant p-value at the 5% level supports unidimensionality
  3. Overall goodness-of-fit tested using Andersen's likelihood-ratio test. Non-significant p-value at the 5% level supports a good fit
