Reliability and validity assessment of the job attitude scale

Abstract

Job satisfaction among nursing assistants (NAs) is associated with NA retention, resident satisfaction, and residents' quality of care. The purpose of this study was to provide psychometric support for a measure of job satisfaction, the Job Attitude Scale (JAS), used with NAs that work in long-term care facilities. We performed a secondary data analysis and used traditional test theory and Rasch analysis to assess the reliability and validity of the JAS. The sample consisted of 508 NAs from 12 nursing homes and 96 NAs from 4 assisted living communities. We found evidence of reliability, validity, and generalizability when the measure was used in both settings and evidence that the JAS has the ability to assess variability in job satisfaction.
