Validity and Reliability Test of Career Self- Awareness Instruments on Victims of Violence With the Rasch Model

Abstract

Background Everyone needs self-awareness about her/his career, without exception, even if she/he is a victim of violence. Victims of violence have a trauma that often affects their lives, including their career development. A new instrument is needed to measure an individual's self-perception of themselves and their work environment. An instrument needs to be tested for validity and reliability before it is used with individuals to assess individuals’ self-awareness about their careers. Career self-awareness instruments measure an individual's talent to understand themselves and the work environment in depth. 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. Results The analysis showed that the unidimensional value fell into the "good" category and thus could describe aspects of the career self-awareness instrument. The analysis of the diagnostic rating scale based on the Andrich threshold showed that the score increased to the appropriate level with the value from 0 to 4. The Cronbach alpha value represents the interaction between a person and an item in the good category. In addition, the person reliability value is found in the sufficient category, while the item reliability is very good. 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.
