Using data from 708 French-Canadian nurses, the present study relies on self-determination theory (SDT) and its proposed motivation mediation model to examine the associations between need satisfaction, work motivation, and various manifestations of psychological wellbeing (work satisfaction, emotional exhaustion, and turnover intentions). To increase the precision and accuracy of these analyses, we relied on analytic approaches that explicitly account for the dual global/specific nature of both work motivation and need satisfaction. Results revealed that nurses' global psychological need satisfaction, and their specific autonomy and competence satisfaction, were positively associated with their global self-determined work motivation and specific intrinsic motivation. In turn, global self-determined work motivation and specific intrinsic motivation were associated with more desirable outcome levels. Nurses' global need satisfaction and specific autonomy satisfaction were also directly associated with more desirable outcome levels. Our results provided support for a partially mediated version of SDT's motivation mediation model.

Background: While the work situation for nurse assistants in residential care is strenuous, they themselves often state that they are satisfied with their job. More knowledge is clearly needed of the interrelationship of variables associated with job satisfaction. This study aims to investigate job satisfaction and explore associated variables among nurse assistants working in residential care.

Methods: A total of 225 respondents completed a questionnaire measuring general job satisfaction, satisfaction with nursing-care provision and measures concerning person-centered care, work climate, leadership, and health complaints. Job satisfaction was the outcome measure and comparisons were made among those reporting low, moderate, and high levels of job satisfaction; multiple regression analyses were used to explore associated variables.

Results: The caring climate and personalized care provision were associated with general job satisfaction. High levels of satisfaction with nursing-care provision were also associated with the general work climate, organizational and environmental support, and leadership. Low job satisfaction was mainly associated with health complaints.

Conclusions: Nurse assistants working in a positive work climate, caring climate, with a positive attitude to their leaders, who receive organizational and environmental support, provide person-centered care and experience a higher degree of job satisfaction. It seems essential, however, to include both general and context-specific measures when investigating job satisfaction in this field as they reveal different aspects of the nurse assistant's work situation.
