Web-Based Training Program Using Cognitive Behavioral Therapy to Enhance Cognitive Flexibility and Alleviate Psychological Distress Among Schoolteachers: Pilot Randomized Controlled Trial

BACKGROUND: Schoolteachers are known to be faced with various stresses in their work. A simple, less onerous, and effective intervention technique that can enhance the stress management skills, particularly, cognitive flexibility, of schoolteachers is needed. OBJECTIVE: This study aimed to determine whether stress management training using a Web-based cognitive behavioral therapy (CBT) program is effective for enhancing the cognitive flexibility of schoolteachers and alleviating their subjective distress. METHODS: This study was conducted in a random controlled design covering public elementary schoolteachers. Teachers allocated to the intervention group received 120 min of group education and completed homework using a Web-based CBT program that lasted for 3 months. The items of outcome evaluation were cognitive flexibility and subjective distress, and the efficacy of intervention was evaluated at 3 months after intervention. RESULTS: A total of 240 participants were randomly allocated to the intervention group (120 individuals) and the control group (120 individuals). On the basis of the principle of intention to treat, the intervention group and the control group were compared regarding the amount of change from before intervention to after intervention, using a general linear model. Scores of cognitive flexibility and subjective distress were significantly more improved in the intervention group than in the control group. CONCLUSIONS: The results of this study suggest that simple stress management training using a Web-based CBT program in elementary schoolteachers enhances cognitive flexibility and alleviates subjective distress.
