Background and Purpose: To assess the psychometric properties of Chinese versions self- efficacy and outcome expectations on osteoporosis medication adherence (SEOMA-C and OEOMA-C) scales. Methods: Back-translated tools were assessed by internal consistency and R2 by structured equation modeling, confirmatory factor analyses, hypothesis testing, and criterion-related validity among 110 (81 females, 29 males) Mandarin-speaking immigrants (mean age = 63.44, SD = 9.63). Results: The Cronbach's alpha for SEOMA-C and OEOMA-C is .904 and .937, respectively. There was fair and good fit of the measurement model to the data. Previous bone mineral density (BMD) testing, calcaneus BMD, self-efficacy for exercise, and osteoporosis medication adherence were positively related to SEOMA-C scores. Conclusion: These scales constitute some preliminary validity and reliability. Further refined and cultural sensitive items could be explored and added. © 2014 Springer Publishing Company.
