title: Reliability and validity of the self-efficacy and outcome expectations for osteoporosis medication adherence scales.
abstract: OBJECTIVE
  The purpose of this study was to test the reliability and validity of the self-efficacy and outcome expectations for osteoporosis medication adherence measures (SEOMA and OEOMA).
  
  
  METHODS
  This was a descriptive study involving a single face-to-face interview.
  
  
  METHODS
  The study included 152 older adults with a mean age of 85.7 (+) 5.5 years, the majority of whom were Caucasian (99%), female (74%), and unmarried (75%).
  
  
  METHODS
  In addition to the SEOMA and OEOMA measures, demographic information (age, gender, and marital status) and other health behaviors (exercise and osteoporosis medication use) were explored.
  
  
  RESULTS
  There was evidence of reliability of the SEOMA and OEOMA based on internal consistency and R values. Evidence of the validity of the SEOMA and OEOMA measures was based on confirmatory factor analysis and hypothesis testing.
  
  
  CONCLUSIONS
  This study is an important first step to developing reliable and valid measures of self-efficacy and outcome expectations for adherence to osteoporosis medications.
  
  
  CONCLUSIONS
  The SEOMA and OEOMA can be used to evaluate self-efficacy and outcome expectancy beliefs related to osteoporosis medication use in older adults and interventions developed to strengthen those beliefs and improve medication adherence.
