`questionnaire_filter`	Character. A regex filter that identifies variable names that are part of a questionnaire.
`item_filter`	Character. A regex filter that identifies the incremental part of multiple items belonging to the same questionnaire (e.g., if items are labelled c("a1", "a2", "a3"), then the item_filter would be `"\d$"` ).
`skip_questionnaires`	Character vector. Names of the questionnaires to skip.
`questionnaire_length`	Integer. Minimum number of items required to be included in the list of questionnaires.

A named list with elements corresponding to the questionnaires identified. Each element is a character vector with the variable names belonging to that questionnaire.
