The Munich ChronoType Questionnaire (MCTQ) was developed by Roenneberg et al. and has been in use since 2000 (Roenneberg et al. 2003, JBR). Since then, the MCTQ has been progressively optimised. It consists of a core module that is required to determine chronotype and several additional, optional modules on personal data, light exposure, substance use, etc. The most recent version of the MCTQ (both core and complete with all modules) can be downloaded below. Please request permission for use by emailing Till Roenneberg (till.roenneberg(at)med.uni-muenchen.de).
We meanwhile offer a service that involves entering your data in our database whereafter you will receive a full evaluation from us. You can view and complete an agreement that settles this by clicking the link http://thewep.org/en/wep_project_agreement.html The entered data belongs entirely to you. They will be marked as a WeP-Project and will not be used for our analyses, except for very general analyses such as geographical distributions or how many people use an alarm clock. For funding our service and to guarantee future support, we ask a fee. Prices are listed in the WeP Project Agreement.
