Overview This repository contains the code and analysis for Irakli Matcharashvili's project in Educational and Psychological Measurement. The project focuses on the internal structure of a test, identifying subconstructs related to Health Anxiety Levels (HAL), Cognitive Performance Levels (CPL), Emotional Well-being Levels (EWL), and Physiological Wellness Levels (PWL).
Project Components
-
Theory and Factor Analytic Diagram Irakli identified subconstructs and created a factor analytic diagram to represent the internal structure of the test. The identified subconstructs and associated items are detailed in the project documentation.
-
Confirmatory Factor Analysis (CFA) The CFA results are as follows:
χ² = 278.532; df = 113; p = 0.000 CFI = 0.961 TLI = 0.953 RMSEA = 0.060 (90% CI: 0.051 - 0.069) These fit indices indicate a good fit of the proposed model to the data. The Chi-square statistic suggests that the model does not fit the data perfectly, but the other fit indices support the overall model validity.
-
Factor Loadings and Correlations The factor loadings with standard errors are provided for all items (n=403). Additionally, correlations between factors, their directions, and magnitudes are detailed in the documentation.
-
APA Write-up An APA-style write-up is included, summarizing the CFA results, factor loadings, and correlations. Salient indicators for each factor are highlighted, along with interpretations of the correlations between factors.
-
Appendices Appendix 1 contains the questionnaire used in the study, and Appendix 2 includes the R script used for analysis.
