Social support, role clarity and job satisfaction: a successful combination for nurses.

AIM: To analyse the moderating effect of role clarity on the relationship between social support (supervisor and colleagues) and job satisfaction. BACKGROUND: The social support of supervisors and co-workers and the clarity of roles are important antecedents of job satisfaction. According to the Conservation of Resources theory, the interaction of the instrumental nature of role clarity and social support would result in higher levels of job satisfaction in nursing. METHODS: Through a convenience sample, a final sample of 191 participants (64.92% registered nurses, 35.08% nursing assistants) was obtained from a private hospital complex in Portugal. Hierarchical linear regression models were carried out to check the moderating function of role clarity. RESULTS: Regression models showed the moderating effect of role clarity. Nursing staff with high social support from their supervisors and peers showed higher scores in job satisfaction when role clarity was high. CONCLUSION: An adequate description of roles, through clear and detailed information regarding expected functions, responsibilities and behaviour, allows the effect of social support from supervisors and co-workers on job satisfaction to be stronger. IMPLICATIONS FOR NURSING PRACTICE: Strategies such as defining responsibilities, setting clear expectations and role analysis allow a reduction in sources of uncertainty in jobs. Training in communication and feedback skills would improve the social support given by supervisors and colleagues. IMPLICATIONS FOR NURSING POLICY: Hospital boards and nurse managers should be aware of the importance of clarifying roles, responsibilities, and functions of each professional category and hierarchical level for the provision of adequate quality of care.
