Abstract

Purpose: The purpose of this study was to report the instrument modification and validation processes to make existing health beliefmodel scales culturally appropriate for Korean Americans (KAs) regarding colorectal cancer (CRC) screening utilization.
Methods: Instrumenttranslation, individual interviews using cognitive interviewing, and expert reviews were conducted during the instrument modificationphase, and a pilot test and a cross-sectional survey were conducted during the instrument validation phase. Data analyses of thecross-sectional survey included internal consistency and construct validity using exploratory and confirmatory factor analysis.
Results:The main issues identified during the instrument modification phase were (a) cultural and linguistic translation issues and (b) newly developeditems reflecting Korean cultural barriers. Cross-sectional survey analyses during the instrument validation phase revealed that allscales demonstrate good internal consistency reliability (Cronbach’s alpha=.72~.88). Exploratory factor analysis showed that susceptibilityand severity loaded on the same factor, which may indicate a threat variable. Items with low factor loadings in the confirmatory factoranalysis may relate to (a) lack of knowledge about fecal occult blood testing and (b) multiple dimensions of the subscales.
Conclusion:Methodological, sequential processes of instrument modification and validation, including translation, individual interviews, expert reviews,pilot testing and a cross-sectional survey, were provided in this study. The findings indicate that existing instruments need to beexamined for CRC screening research involving KAs.
