Exploring the Characteristics of Individuals Grouped Based on the Multimodal Optimized Treatment for Insomnia Framework Among Individuals Complaining of Insomnia

OBJECTIVE: This study aimed to explore the feasibility of the Multimodal Optimized Treatment for Insomnia Framework (MOTIF) among people with insomnia symptoms among the general population. METHODS: An online survey among people in the general population complaining of insomnia was conducted anonymously. Participants were categorised into two groups based on 6 hours of time in bed (TIB). Each group was further clustered into two groups based on favourable attitudes toward taking hypnotics. Their psychological states were assessed using the Insomnia Severity Index (ISI), Patient Health Questionnaire-9 (PHQ-9), Dysfunctional Beliefs and Attitudes about Sleep-6 (DBAS-6), Adaptive Cognition and Behaviors about Sleep-6 (ACBS-6), and Depressive Symptoms Inventory-Suicidality Scale (DSI-SS). RESULTS: There were 600 responses collected, with 548 responses analysed from people whose bedtime was between 9:00 PM and 1:00 AM. In total, 86.1% were categorized as individuals who can sleep without medications, while 13.9% as individuals who cannot. The ISI score was significantly higher among individuals with TIB ≤6 hours. Based on the attitude toward taking hypnotics, the proportions of participants in each category were 46.9%, 39.2%, 7.8%, and 6.0%. The ISI and DSI-SS scores (18.7±5.3 and 2.9±2.6, respectively) were significantly higher among the group who cannot sleep without medications and who had a favourable attitude to taking hypnotics. The proportion of participants taking hypnotics was lowest among the group who cannot sleep without medications and had an unfavourable attitude to taking hypnotics. CONCLUSION: Individuals unable to sleep without hypnotics exhibit more severe insomnia symptoms and higher psychological distress.
