1. Can I get permission to use one of the questionnaires?
Yes, you are welcome to use our questionnaires. We would appreciate it if you would inform us that you will use one of the questionnaires and share the results/publication of your results with us.
2. Can I translate one of the questionnaires?
Yes, you are allowed to translate the questionnaires. Please, first check whether there is already a version in that language. For the translation of a questionnaire, some steps need to be taken: 1) you translate the questionnaire, 2) you let someone else translate your version of the questionnaire back to English, 3) you send the back-translated English version of your questionnaire to us, 4) we check the back-translation and suggest improvements, 5) you adjust the translated questionnaire (if necessary), and 6) you send a copy of the final version to us, and we will add your translation to our website. We also welcome any output, e.g., scientific publications, which we would also like to publish to our website.
3. Are there cut-off scores or norm scores available for the questionnaire?
No, we have no cut-off scores or norm scores available for the questionnaire, because we only use group mean scores to compare between, for example, groups of adolescents with and without ASD.
4. Is it possible to use the questionnaire as a screening instrument?
No, we do not have cut-off scores or norm scores available for the questionnaires, because we only use group mean scores to compare between groups. Therefore, the questionnaires are not useful as a screening instrument.
