Create a Likert question
question_likert(prompt, labels, required = FALSE, name = NULL)
| prompt | the prompt for the question |
|---|---|
| labels | the labels on the Likert scale |
| required | is a response to the question required? |
| name | a convenient label for the question |
A question object to be passed to trial_survey_likert().
The question_likert() function is designed to be called when
using trial_survey_likert() to construct a survey page that contains
Likert scale response items. When rendered as part of the study, the text specified
by the prompt argument is shown to the participant, with a set of ordered
categories displayed along a horizontal line. The labels for these categories
are shown beneath the line, and the participant responds by selecting a radio button
that is placed along the line. If required = TRUE the participant will not
be allowed to continue to the next trial unless an answer is provided.
The name argument should be a string that provides a convenient
label for the question. If left unspecified, jsPsych defaults to labelling
the questions within a survey page as "Q0", "Q1", "Q2", etc.
Survey page trials are constructed using the trial_survey_text,
trial_survey_likert, trial_survey_multi_choice and
trial_survey_multi_select functions. Individual questions for survey
trials can be specified using question_text,
question_likert and question_multi.
