qsort

Overview

qsort is a package that allows scoring Q-sort data, using criteria sorts and derived scales from subsets of items. This package includes descriptions and scoring procedures for four different Q-sets:

Attachment Q-set (version 3.0) (Waters, 1995);
California Child Q-set (Block & Block, 1969);
Maternal Behaviour Q-set (version 3.1) (Pederson et al., 1999);
Preschool Q-set (Baumrind, 1968 revised by Wanda Bronson).

qsort package includes 7 objects:

qsort_score() a function for scoring Q-sort data;
ex_qsort a list containing four example data frames for the referred Q-sets;
print_cards() a function for printing Q-set item cards.
qset_aqs a data frame containing the Attachment Q-set (aqs; version 3.0);
qset_ccq a data frame containing the California Child Q-set (ccq);
qset_mbqs a data frame containing the Maternal Behaviour Q-set (mbqs; version 3.1);
qset_pq a data frame containing the Preschool Q-set (pq);

Read the documentation (with ?qset_aqs, ?qset_ccq, ?qset_mbqs and ?qset_pq) to learn more about which criteria sorts and scales are included for each Q-set. Or click the R documentation badge at the top of this page.

Installation

To install qsort package from CRAN:

install.packages("qsort")

The qsort package can also be installed from GitHub:

# to install packages from github you first need to install devtools package from CRAN.
# if you haven't installed devtools already just type:
install.packages("devtools")

# to install qsort from github type:
devtools::install_github("joaordaniel/qsort")

Example

The example bellow shows how to use qsort_score() function to compute scores from California Child Q-sort data, present in ex_qsort datasets (ex_qsort$ccq).

library(qsort)
data_ccq <- qsort_score(ex_qsort$ccq, qset_ccq, qsort_length = 100, item1 = "ccq1", subj_id = "participant", group_id = "classroom")
data_ccq

Read qsort_score help file (?qsort_score) to learn more about the function’s four arguments, and qset_ccq help file (?qset_ccq) to learn more about variables’ names.

Print cards

To print item descriptions in separate cards use print_cards() function. The example bellow uses the print_cards() function to create a pdf file with Attachment Q-set items, in a user defined directory (working directory in this case - getwd()) .

library(qsort)
print_cards(qset_aqs, desc_col = "description", dir.print = getwd())

Read print_cards() help file (?print_cards) to learn more about the function’s two arguments.
