Significant costs are associated with the turnover rate of certified nursing assistants (CNAs) in skilled nursing facilities (SNFs), and turnover impacts the quality of care for residents of the SNFs through disruption of care. The purpose of this quantitative cross-sectional study was to identify the leadership characteristics of supervisors most associated with the job satisfaction (JS) of CNAs in SNFs. Herzberg's dual factor theory was used as the theoretical framework to explain the relationship between the leadership characteristics and the associated JS. The research question was used to examine the independent variables of trust, teamwork, supportive supervision, leader-follower relationships, and empowerment of supervisors in SNFs that help predict the dependent variable, JS of CNAs. A random sampling of the population of CNAs from 120-bed SNFs located in Florida completed online surveys that included the Organizational Trust Inventory, the Conditions for Work Effectiveness Questionnaire II, and the Benjamin Rose Nurse Assistant Job Satisfaction Scale. Multiple linear regression was used to analyze data to determine the effects of the leadership characteristics on the JS of CNAs in SNFs. Results indicated that the increased levels of trust negatively impact the JS of the CNAs, whereas increased levels of empowerment increase JS. Implementing strategies to address the needs of CNAs positively impacts society by improving the lives of the workers and increasing CNA retention, thus improving the lives of vulnerable members of society through enhanced quality of care.
