Objective: This study was conducted to assess the effectiveness of feedback in a virtual attention training program to improve the attentional characteristics of sluggish cognitive tempo (SCT). Method: The SCT group ( N = 60) and control group ( N = 30) were identified, and the attention network test-revised (ANT-R) was performed to measure attention characteristics. Based on this result, a virtual reality (VR) feedback attention training program was developed to improve the efficiency of engagement and disengagement of attention in SCT. Sixty participants with SCT were recruited and grouped into two conditions: VR feedback ( n = 30) and no-feedback ( n = 30) conditions. Results: The results show that the VR attention training program with feedback significantly improves the attention-orienting network. Conclusion: This suggests that it is necessary to provide immediate feedback for effective attention training for SCT and continuous intervention may be possible when feedback is provided together.
