Examining the Supervision Work Alliance Scale: A Rasch Model Approach
Abstract
Background:
The supervisory working alliance has a role in facilitating guidance and counseling supervisors in providing understanding of how the service works. Measuring the level of supervision work alliance is one way that can be done to find out whether a supervisor has a good supervisory work alliance or not.
Objective:
The research aims to describe the quality of the Supervision Work Alliance Scale (SWAS) instrument.
Materials and Methods:
The study employed a cross-sectional method with a quantitative research design. Participants in this study were counseling teachers implementing the internship program with 17 males and 55 females. This type of parameter needs to be identified by the category coefficient of the RASCH scoring function model for polycotomic responses.
Results:
The results show that as many as 34 items proved to be compatible with SWAS instruments. The cronbach alpha of the instrument was 0.91 which means that the all items were in the high category of reliability. The misfit items were only 5,88, so all of the items in SWAS were well understood by the participants.
Conclusion:
The development of SWAS instrument is valid and reliable, so it can be used to measure the variable of the supervisory work alliance
