To explore the effect of psychological intervention on language ability recovery and mood state of hearing impaired adolescents. 80 cases of hearing impaired adolescents aged 7-18 in our hospital from June 2019 to June 2020 were randomly divided into observation group and control group, 40 cases in each group. All the children were treated with cochlear implantation, and the control group was given routine speech training and health education. The observation group was given psychological intervention nursing in the whole treatment process on the basis of routine nursing. The treatment effect, language ability recovery, mood state and ABC score of the two groups were compared. The total effective rate of the observation group was 92.50%, and that of the control group was 75.00%, which was higher than that of the control group (P<0.05); there was no significant difference in speech formation, hearing ability and auditory perception between the two groups before nursing (P>0.05), but the speech formation, hearing ability and auditory perception of the two groups were significantly improved after nursing the score of the observation group was higher than that of the control group (P<0.05); there was no significant difference in the spirit, control, ability, tolerance of negative emotions and acceptance changes between the two groups before nursing (P>0.05); after treatment and nursing, the spirit, control, ability, tolerance of negative emotions and acceptance changes of the two groups were significantly decreased, and the score of the observation group was lower than that of the control group (P<0.05). There was no significant difference in the scores of excitement, irritability, stereotyped behavior and inappropriate language between the two groups before nursing (P>0.05), but after nursing, the scores of the two groups decreased, and the observation group was less than the control group, the difference was statistically significant (P<0.05). On the basis of routine treatment and nursing, psychological nursing intervention can improve the treatment effect of children, improve the recovery of language ability, reduce negative emotions and improve the mood of children, which is worthy of clinical application and promotion.
