The Comparison Score for the Spanish language translation of the ADOS-2 can be calculated using a procedure identical to that used for the English version. However, the algorithm form for the Spanish language translation does not include the scoring information for the Comparison Score on the form itself.
To calculate this score after completing the algorithm form, there are four options:
1. Refer to Appendix C of the English language ADOS-2 Manual, which includes full scoring information for the Comparison Score for all ADOS-2 Modules for which the score is available (i.e., Modules 1, 2, and 3).
2. Refer to the algorithm page of the English language ADOS-2 protocol form that corresponds to the Spanish language module that was administered. The front and back sides of the English language form can be referenced alongside the scores from the Spanish language administration in order to calculate the Comparison Score.
3. Use the English language ADOS-2 scoring CD in conjunction with the protocol form from the Spanish language administration in order to calculate the Comparison Score.
4. Create an account on www.teacorrige.com for a complimentary web-based calculation of the Comparison Score. Each purchased set of Spanish language protocol forms includes a PIN number and instructions for accessing this web-based calculation. Further information about this system can be found in the Spanish language translation of the ADOS-2 Manual.
