Available translations The SIPP was translated simultaneously from English to Dutch and vice versa. Next, the English version was the basis for translating the questionnaire into other languages. As the SIPP is a copyrighted questionnaire, users are not allowed to develop their own translation or to modify translations without our permission. However, users who are interested in being involved in translation, back-translation and validation are encouraged to contact us directly (SIPP@deviersprong.nl).
SIPP-SF (60 items)
For users of the Dutch and English SIPP-SF: please check whether the front page of your questionnaire contains the text “version 2006” or “version december 2005”. If not, the SIPP-SF version you’re using might be an older version.
