Confirmatory Factor Analysis in the Measurement of the TOSCA-3 Guilt Scale

This study aims to evaluate the measurement of guilt in adolescents using the TOSCA-3 (Test of Self-Conscious Affect 3) scale developed by Tangney and Dearing (2002). Guilt is a moral emotion that plays an important role in adolescents' psychological development, motivating them to correct behaviors and repair damaged social relationships. This research uses a quantitative approach with a non-experimental design, involving 225 adolescent respondents aged 15-19 years. Data were collected through questionnaires using an adapted TOSCA-3 scale consisting of eight aspects of guilt. The analysis results indicate that the scale has excellent reliability, with Cronbach’s α of 0.867 and McDonald's ω of 0.869. However, the model fit test (CFA) revealed some fit issues, particularly with CFI and TLI values below the standard. This study suggests modifying certain items to improve the model fit. These findings indicate that the guilt measurement using TOSCA-3 is reliable, although further improvements to the instrument are needed.
