Can personality traits influence occupational stress in multiple sclerosis patients? A one-year longitudinal study.

Recent studies suggest that patients with Multiple Sclerosis (MS) might be at risk of unemployment due to physical and psychological symptoms. Furthermore, MS patients appear to be more exposed to a higher level of occupational stress, which might be linked to some personality characteristics. Our aim was to ascertain, by means of a longitudinal study, whether changes in occupational stress can be predicted by some personality traits, which could thereby become potential targets of therapeutic interventions. This study describes the longitudinal results of a previous work on occupational stress and personality traits in MS patients. Twenty MS patients were reevaluated one year after the baseline assessment. The statistical comparison between the baseline and follow-up visits showed a significant change in the scores on some Occupational Stress Inventory (OSI) subscales-Locus of control total (LOC-tot) and Involvement coping strategies (CI). While Neuroticism and Openness might predict changes in LOC-tot, Conscientiousness appeared to be important in the development of CI at one year. The findings indicate that certain personality traits can influence some longitudinal changes in occupational stress, thus making them useful in predicting stress at workplace.
