Influence of Job Insecurity on Musculoskeletal Disorders: A Mediation Model with Nursing Aides
Abstract
:1. Introduction
- Job insecurity and physical workload are relevant variables for the presence and development of MSSs;
- Psychosocial risks (measured in terms of job demands, social support at work, and job control) have a mediating role in the relationship described in Hypothesis 1. The parallel mediation path model hypothesised is shown in Figure 1.
