BMC Psychol. 2025 Apr 30;13(1):456. doi: 10.1186/s40359-025-02762-5.

ABSTRACT

BACKGROUND: Victims of violence have trauma that often affects career development. A tool is needed to measure a person’s self-perception of self and work environment. The main problems in instrument measurement are items that are not independent of what is measured, instrument tests that are not linear and do not have significant value accuracy, lack of empirical coherence of responses, items, and constructs, and missing data errors. the purpose of solving these problems requires in-depth analysis using the Rasch model.

METHODS: This research examines the validity and reliability of career self-awareness instruments with victims of violence. The research was conducted with 50 victims of violence in Bandung City. A quantitative approach with a cross-sectional study design was used. Data were analyzed using the Rasch model and Winsteps 3.73 application, Rasch model procedures and criteria are unidimensionality, person instrument analysis and item reliability, person item map, item difficulty, item fit, rating scale diagnostics, and item bias detection.

RESULTS: The significance of the research findings is assessed based on unidimensionality in the “good” category, Analysis based on Andrich’s threshold shows the score increased to the appropriate level, Cronbach alpha value represents the interaction between person and item in the good category, and the person reliability value is 0.89 while the item reliability is 0.98.

CONCLUSION: Based on these results, a career self-awareness instrument can be used to assess and measure the level of career self-awareness of victims of violence.
