Guidelines
To learn more about the Munich ChronoType Questionnaire (MCTQ),
see Roenneberg, Wirz-Justice, & Merrow (2003), Roenneberg, Allebrandt,
Merrow, & Vetter (2012), Roenneberg et al. (2015), and Roenneberg, Pilz,
Zerbini, & Winnebeck (2019).
To know about different MCTQ versions, see Juda, Vetter, & Roenneberg
(2013) and Ghotbi et al. (2020).
To learn about the sleep-corrected social jetlag, see Jankowski (2017).
If you're curious about the variable computations and want to have access to
the full questionnaire, see The Worldwide Experimental Platform (n.d.).
Data building and data wrangling
This dataset was created by randomized sampling (see
random_mctq()) and by manual insertions of special
cases. Its purpose is to demonstrate common cases and data issues that
researchers may find in their MCTQ data, in addition to be a suggested data
structure for MCTQ data.
You can see the std_mctq build and data wrangling processes
here.
Variable naming
The naming of the variables took into account the naming scheme used in MCTQ
publications, in addition to the guidelines of the tidyverse style guide.
Variable classes
The mctq package works with a set of object classes specially created to
hold time values. These classes can be found in the hms
and lubridate package.
Duration objects
If you prefer to view Duration objects as
hms objects, run
pretty_mctq(std_mctq).
