Psychometrics & Post-Data Analysis for Jamovi

DEVELOPMENT IS CURRENTLY ON HOLD. CONTACT THE CREATOR FOR DETAILS OR INTEREST IN RENEWING THE PROJECT.

This module is a tool for performing various Psychometric & Post-Data Analyses.

The current tools available are:

• BinaryLogR (Binary Logistic Regression for Differential Item Functioning):

Assessing DIF on dichotomously scored items using a generalized linear model framework (GLIM). By incorporating the GLIM family of methods for detecting DIF in a user-friendly interface, the technical barrier to assessing DIF has been greatly reduced. The development of techniques for assessing of Type-M error rates (Gelman & Carlin, 2014) on DIF-classification thresholds represents a revolution in the interpretability of DIF-flagging, particularly in the context of low-powered research settings. The goal developing this module is to encourage the use of the the GLIM framework in the broader psychosocial measure validation praxis.

• Test ROC (Measure Diagnostics) The TestROC module provides an interface to the cutpointR R-package. This module enables researchers in psychosocial validation work to assess the optimal cutpoints of measures. Additional info to come

In testing/development: - Ordinal logistic regression for DIF

• Design analysis for:

  • T-Test for Mean differences
  • T-Test for Correlations

• Reliability analysis for ordinal measures
