Abstract

Purpose
The purpose of this study was to validate the Needs Assessment Tool for Case Management (NATCM) for use with Korean medical aid beneficiaries.
Methods
Psychometric testing was performed with a sample of 645 Korean medical aid beneficiaries, which included 41 beneficiaries who were selected using proportional sampling method, to examine intraclass correlation coefficients (ICC). Data were evaluated using item analyses, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), Cronbach's alpha, and ICC.
Results
Through psychometric testing the final version of NATCM was found to consist of two subscales: 1) Appropriateness of Health Care Utilization (5 items) and 2) Self Care Ability (6 items). The two subscale model was validated by CFA (RMSEA=.08, GFI=.97, and CFI=.93). Internal consistency measured by Cronbach's alpha was .82, and subscale reliability ranged from .79 to .84. The ICC of the NATCM between case managers was .73 and between case managers and health care professionals. .82.
Conclusion
This study suggests that the final version of NATCM is a brief, reliable, and valid instrument to measure needs of Korean medical aid beneficiaries. Therefore, the NATCM can be effectively utilized as an important needs assessment as well as outcome evaluation tool for case management programs in Korea.
