Trait-anxiety and job psychosocial conditions as determinants of mental health in nursing

Background and objective
Job stress can have important consequences on the physical, mental or social health of the workers. A considerable number of studies have shown that the nursing community is especially vulnerable to suffering stress due to their work characteristics. The purpose of this research was to determine the relationship between perception of psychosocial risk factors at work, trait-anxiety and mental health in nursing.

Method
Two hundred and ten nurses from various public hospitals in Madrid Province have participated in this study. The perception of psychosocial risk factors was evaluated with DECORE and NASA-TLX questionnaires, trait-anxiety was measured by STAI questionnaire and mental health by GHQ-28 questionnaire.

Results
The results of the multiple regression analysis revealed that trait-anxiety was the variable most related to mental health. To explore the isolated association between working conditions and nurses’ mental health, partial correlations controlling the nurses’ trait-anxiety level were calculated and significant correlations were found between mental health and some psychosocial risk factors like organizational support, cognitive and temporal demands and control/autonomy at work.

Conclusion
Trait-anxiety influences the relations between working conditions and nurse's mental health, but regardless of the trait-anxiety level of nurses, the adverse psychosocial conditions of the workplace are directly associated with poorer mental health.
