Introduction Total Worker Health® programs aim to improve health climate, or employees’ perceptions of support for physical and mental health from coworkers, supervisors, and upper management. Health climate is linked to physical and mental health outcomes. The recently developed Multifaceted Organizational Health Climate Assessment (MOHCA) assesses general health climate and three subfactors of workgroup, supervisor, and organizational health climate in working adults and correctional employees. There is little evidence of the MOHCA’s validity and reliability properties among service, clerical, and health care workers in a large hospital system. Objectives To investigate validity and reliability properties of the MOHCA in this sample, we examined: 1) the structural validity of the MOHCA’s general and subfactor scales and 2) targeting of items to persons and measurement invariance of items among racial, sex, and income subgroups. Methods We recruited 1,283 employees (45.9% Caucasian; 67.7% female; 77.9% Results A revised general and four-subfactor structure with workgroup, supervisor, organizational, and organizational responsiveness health climate subscales explained 73.7% of response variation with adequate reliability (Cronbach’s alpha=0.60–0.91). Compared with the original structure’s fit, this revised structure’s fit was superior (Chi-square = 33.245, df=16; Root Mean Square Error Approximation=0.029; Comparative Fit Index=0.997). One item demonstrated misfit to Rasch models (Infit Mean Square>1.5). Male and Non-Caucasian workers were less likely to report a workgroup supportive of recovery (p Conclusions A revised four-subfactor MOHCA structure with a new organizational responsiveness health climate subscale demonstrated adequate validity and reliability properties to assess health climate scores among service, clerical, and health care workers in a large hospital system.
