Effects of Intervention Strategies-Based on Positive Psychology on the Emotional Cognition, Mental Health, and Recovery of Speech Function in Speech Disabilities

Background: Compared with able-bodied people, speech disabilities are more prone to various mental health problems. We aimed to explore the impact of positive psychology-based intervention strategies on emotional cognition, mental health, and recovery of speech function in speech disabilities. Methods: In May 2023, 306 cases of speech disabilities were selected from 112 village committees and 129 neighborhood committees in Jingmen City, China. The control group was given routine speech rehabilitation training, and the observation group was given an intervention strategies-based on positive psychology based on the above training. The Symptom Checklist-90 (SCL-90), Chinese Facial Emotion Test (CFET), Comprehensive Function Assessment for Disabled Children (CFADC), and Boston Diagnostic Aphasia Examination (BDAE) were used to evaluate the two groups of patients before and after intervention. Results: After the intervention, the mental state scores (psychotic, obsessive-compulsive symptoms, somatization, paranoia, terror, hostility, anxiety, and depression) of the observation group were lower than those of the control group (P<0.05). The correct emotional scores in the observation group were higher than those in the control group were. However, the remote error scores of the observation group were lower than those of the control group were. The difference was also statistically significant (P<0.05). The cognitive function score, speech function score, and BDAE score (retelling, writing, fluency, and reading comprehension) of the observation group were all higher than those of the control group (P<0.05). Conclusion: The intervention strategies-based on positive psychology could promote the improvement of health problems and speech function in speech disabilities.
