In LCBC-UiO/Questionnaires: Package with functions to calculate components and sums for LCBC questionnaires

Column names

Questions with multiple subquestions should be named in a similar manner, suffixed by the alphabetical index (psqi_5a, psqi_5b etc.). For questions 5j and 10j, the frequency of occurence should have the names psqi_5j and psqi_10e, and the freehand explanations should have any type of suffix after this to indicate a text answers (i.e. psqi_5j_Desc or psqi_5j_string, psqi_5j_freehand). As an example, LCBC has the following set-up:

• psqi_1
• psqi_2
• psqi_3
• psqi_4
• psqi_5a psqi_5b psqi_5c psqi_5d psqi_5e psqi_5f psqi_5g psqi_5h psqi_5i psqi_5j psqi_5j_Coded psqi_5j_Desc
• psqi_6
• psqi_7
• psqi_8
• psqi_9
• psqi_10 psqi_10a psqi_10b psqi_10c psqi_10d psqi_10e psqi_10e_Desc psqi_10e_Coded
• psqi_11a psqi_11b psqi_11c psqi_11d

4-option questions coding

All 4-option questions need to be coded 0-3, not 1-4.

Time formats

For question 1, 3 and 4 (bedtime, rising time, hours of sleep), data should be punched as "HH:MM". Question 2 should be punched as minutes in numbers.
