Key Points

A second course of digital CBT-I may improve ISI remission in chronic insomnia patients who didn't respond initially.
In the pilot study, those who underwent repeated self-guided interventions experienced notable improvements.
Using randomized controlled trials could provide stronger evidence to support the efficacy of this digital intervention.
Further research is essential to establish the long-term effectiveness and feasibility of repeated digital CBT-I.

Abstract

The present study suggests that a second course of digital CBT-I may benefit chronic insomnia patients who initially fail to achieve ISI remission after the first round of self-guided digital CBT-I. However, larger randomized controlled trials are needed to definitively assess its effectiveness.
