Objective To investigate effects of mental nursing on psychological state of patients with pneumoconiosis. Methods 160 pneumoconiosis patients were divided into 8 groups randomly,and 20 patients were included in each group. Psychological characteristics were observed before mental nurs-ing, and 15, 30 and 60 days after mental nursing. The numbers of the youth, the middle-aged and the el-derly patients who demonsrated four or more kinds of psychological characteristics after 60 days mental nursing were compared.320 patients of the same kind were divided into the two aspects of mental nursing group and all aspects of mental nursing group, the number of patients who appeared four or more kinds of psychological characteristics after 60 days mental nursing was recorded. Results The number of pneu-moconiosis patients who clearly appeared four or more kinds of psychological characteristics decreased after 15 days, but it had no statistical significance, the number decreased significantly after 30 days and 60 days of mental nursing, and the latter decreased more significantly.Both of the numbers of two aspects of mental nursing group and all aspects of mental nursing group decreased significantly, and the latter decreased more significantly.The number of the youth decreased most significantly, while it had no statistical significance between the middle-aged and the elderly group. Conclusions Mental nursing for the pneumoconiosis pa-tients is a long-term project, comprehensive mental nursing to pneumoconiosis patients has great influence, but the influence varies for patients with different ages.
