Score a gorilla Questionnaire Builder 2 questionnaire using a survey key

Like gorilla_q_keyed(), but for questionnaires made with Questionnaire Builder 2. See that function for how survey keys work and what the columns of the key (sum, rev, adj, scaleName, Subscore, qual and ignore) mean.

Usage

gorilla_q_keyed_qb2(
  data,
  keyout = FALSE,
  qlist = NULL,
  keylist = NULL,
  items = F,
  key_folder = NULL
)

Arguments

data

The list of data from a gorilla import, or just the questionnaire data (data_q). It has to be in long format.

keyout

Set to TRUE to write out a new blank key for each questionnaire, from the data.

qlist

The names of the questionnaires (Task.Name in gorilla) to score. If NULL, all of them.

keylist

Names of the key files to use, if they are not the same as the names in qlist. Should be the same length as qlist.

items

If TRUE, also return the individual item scores.

key_folder

Folder where the survey keys are kept. If NULL, the folder survey_key in the working directory is used.

Value

A data.table with one row per participant (pid) and a column for each scale (and subscale).

Details

Differences from gorilla_q_keyed(): the items are identified by the Key column of the QB2 data, only rows with Response.Type "response" are used, duplicated answers are not removed, and items with sum = 0 are not returned separately.
