Relationship between mental health and job efficiency.

A homogeneous group of 153 Merchant Marine Officers were analysed on Seafarers' Mental Health Questionnaire (SMHQ) to evaluate their mental health state. The confidential reports of the officers relating to their job performance were scrutinised to determine the level of job efficiency. Individuals obtaining more than the mean effective percentage score were allotted to the high-efficiency group and those obtaining less, to the low-efficiency group. The results obtained show significant mean differences on almost all the mental health dimensions except sexual satisfaction, thus revealing that the job efficiency of seafarers is influenced by different aspects of mental health adjustments.
