Assemble an instrument

Usage

panel_instrument(items, randomize = "option_order")

Arguments

items: A list of panel_items (item_likert(), item_choice(), item_open()), or a single item, which is wrapped in a list. Ids must be unique.
randomize: Which orders to randomize per respondent. The only implemented value is "option_order" (the default): the options of a choice item are permuted per response, and a Likert scale is shown reversed for a random half of responses (an ordered scale has two readable orders, not k!). "item_order" is refused: every persona-item pair is an independent request, so the model never sees a questionnaire order and shuffling one would fabricate an exposure that was not administered. character(0) randomizes nothing. What each respondent saw is recorded in the responses.

Value

An object of class panel_instrument.

Examples

panel_instrument(list(
  item_likert("trust", "How much do you trust the city council?"),
  item_open("reason", "What is the main reason for your answer?")))
