resquin (response
quality indicators) provides functions
to calculate survey data quality indicators to help identifying
low-quality responses (Bhaktha, Silber, and
Lechner 2024; Curran 2016; Vaerenbergh and Thomas 2013).
resp_styles() and resp_distributions() provide
response quality indicators geared towards multi-item scales or matrix
questions. Both multi-item scales and matrix questions present survey
respondents with multiple questions which have the same response format,
meaning the same number and labeling of response options.
At the moment, resquin provides two functions:
resp_styles() - Calculates response style indicators
(e.g. extreme response style or middle response style).resp_distributions() - Calculates response distribution
indicators (e.g. intra-individual mean and standard deviation over a set
of survey questions).Two more functions are planned:
resp_patterns - Calculates response pattern indicators
(e.g. straightlining)resp_times - Calculates response time indicators
(e.g. median item response time)For information on how to use resquin see the vignettes

resquin is available via CRAN and github. To install
resquin from CRAN or github, you can use one of the
following commands:
# Install resquin via CRAN
install.packages("resquin")
# Install development version of resquin with devtools
devtools::install_github("https://github.com/MatRoth/resquin")
# Install development version of resquin with pak
pak::pak("https://github.com/MatRoth/resquin")To use resquin, supply a data frame containing survey
responses in wide format to either resp_styles() or
resp_distributions().
# load resquin
library(resquin)
# A test data set with three items and ten respondents
testdata <- data.frame(
var_a = c(1,4,3,5,3,2,3,1,3,NA),
var_b = c(2,5,2,3,4,1,NA,2,NA,NA),
var_c = c(1,2,3,NA,3,4,4,5,NA,NA))
