Methods: a total of 92 elderly patients with depression were selected as the sample. The study period was from June 2021 to June 2022. The samples were divided into conventional group and cognitive group with 46 samples in each group. The former received conventional care while the latter received cognitive psychological care to assess depression, observe coping styles, and investigate compliance and satisfaction. Results: before nursing, the depression status of each elder was known through the dimensions of HAMD, SDS, etc. There was no difference in this index between the cognitive group and the conventional group (P>0.05). After nursing, the depression of each elder was understood through the dimensions of HAMD, SDS, etc. the index in the cognitive group was lower than that in the conventional group, with significant difference (P<0.05). Before nursing, the coping styles of the elderly were assessed from both positive and negative dimensions. there was no difference between the cognitive group and the conventional group (P>0.05). After nursing, the coping styles of each elderly person were evaluated from both positive and negative dimensions, among which the positive coping score was higher in the cognitive group than in the conventional group after statistics, while the negative coping score was lower in the cognitive group than in the conventional group after statistics, with significant difference (P<0.05). According to the statistics of the compliance under each intervention plan, this value was 95.65%(44 cases) in the cognitive group, which was higher than 78.26%(36 cases) in the conventional group after examination and investigation, with significant difference (P<0.05). According to the statistics of satisfaction degree under each intervention plan, this value was 95.65%(44 cases) in the cognitive group, which was higher than 76.09%(35 cases) in the conventional group after the examination and investigation, with a large difference (P<0.05). Conclusion: cognitive psychological nursing can be popularized, which can keep the elderly in a positive coping state, effectively control the depression, and the elderly have a high degree of satisfaction.展开更多
