An interventional study of Internet-based Cognitive Behavioral Therapy for Insomnia (CBT-I) and Online Patient Education in Tinnitus and Insomnia, sponsored by Eye & ENT Hospital of Fudan University. Not yet recruiting at 1 site in China. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-08-18.

This single-center, single-blind, randomized controlled trial is designed to evaluate the efficacy of therapist-guided, internet-based cognitive behavioral therapy for insomnia (CBT-I) compared with patient education in patients with chronic subjective tinnitus and clinically significant insomnia. A total of 168 participants will be randomized in a 1:1 ratio to receive either an 8-week internet-based CBT-I intervention or an online patient education intervention. The primary outcome is the between-group mean difference in Tinnitus Handicap Inventory (THI) score at 2 months after randomization. Secondary outcomes include insomnia severity, subjective sleep parameters, tinnitus loudness, anxiety and depression symptoms, and dysfunctional beliefs and attitudes about sleep. Participants will be assessed at baseline, 1 month, 2 months, 3 months, and 5 months.
Insomnia is one of the most common comorbidities in patients with chronic tinnitus and is closely associated with tinnitus-related distress and impaired quality of life. Although CBT-I is an established treatment for insomnia, access to conventional face-to-face CBT-I may be limited by the availability of trained therapists, geographic barriers, and time constraints.
This study is designed to evaluate whether therapist-guided, internet-based CBT-I can improve tinnitus-related distress and sleep-related outcomes in patients with chronic subjective tinnitus and clinically significant insomnia.
Eligible participants will be recruited at the Eye \& ENT Hospital of Fudan University and randomly assigned in a 1:1 ratio to either the internet-based CBT-I group or the patient education group. Both interventions will be delivered through smartphone-based platforms over an 8-week period.
The CBT-I intervention consists of eight weekly modules incorporating stimulus control, sleep restriction therapy, cognitive restructuring, relaxation and mindfulness practices, and sleep hygiene education. Participants will complete daily relaxation exercises and weekly homework assignments, with treatment progress monitored by trained therapists through the online platform.
The patient education group will receive a non-individualized online education package covering general information about tinnitus and insomnia, their potential interaction, and general recommendations for sleep and lifestyle management. The educational materials will remain accessible throughout the intervention period without therapist involvement.
The study will follow the intention-to-treat principle. Longitudinal outcomes will be analyzed using mixed-effects models incorporating treatment group, time, and treatment-by-time interaction.

Participants randomized to the experimental arm will receive an 8-week therapist-guided, internet-based cognitive behavioral therapy for insomnia (CBT-I) program. The intervention is designed to improve insomnia symptoms and will be delivered through a smartphone-based online platform. Participants will complete weekly CBT-I modules and related homework assignments during the 8-week intervention period, with follow-up assessments conducted after the intervention.
Other: Internet-based Cognitive Behavioral Therapy for Insomnia (CBT-I)
Participants randomized to the comparator arm will receive an 8-week online patient education intervention. The intervention provides general educational information about tinnitus, insomnia, their potential relationship, and general recommendations for sleep and lifestyle management. Participants will have access to the educational materials throughout the 8-week intervention period.
Other: Online Patient Education
The internet-based CBT-I intervention will be delivered over 8 weeks through a smartphone-based online platform. The program consists of eight weekly modules incorporating core components of CBT-I, including stimulus control, sleep restriction therapy, cognitive restructuring, relaxation and mindfulness practices, and sleep hygiene education. Participants will complete daily relaxation exercises and weekly homework assignments. Treatment progress will be monitored through the online platform, and trained therapists will review participants' progress and provide feedback during the intervention period.
The online patient education intervention will provide non-individualized educational materials covering tinnitus and insomnia, their potential interaction, and general strategies for sleep and lifestyle management. The educational materials will be delivered through a smartphone-based online platform and will remain accessible throughout the 8-week intervention period.
Tinnitus Handicap Inventory (THI)
The Tinnitus Handicap Inventory (THI) is a 25-item self-report questionnaire assessing the functional, emotional, and catastrophic impact of tinnitus. Each item is scored as "yes" (4 points), "sometimes" (2 points), or "no" (0 points), with higher total scores indicating greater tinnitus-related impairment.
Time frame: 1 month, 2 months, 3 months, and 5 month from baseline
Insomnia Severity Index (ISI)
The Insomnia Severity Index (ISI) is a 7-item self-report questionnaire assessing the severity and impact of insomnia during the preceding two weeks. It evaluates sleep initiation and maintenance difficulties, early morning awakening, dissatisfaction with sleep, daytime impairment, noticeability of sleep problems, and distress associated with sleep difficulties.
Time frame: 1 month, 2 months, 3 months, and 5 month from baseline
Sleep Onset Latency (SOL)
Sleep onset latency (SOL) will be assessed using a daily sleep diary. SOL is defined as the amount of time required to fall asleep after going to bed. Weekly average SOL will be calculated for outcome analysis.
Time frame: Baseline and during the 8-week intervention period
Wake Time After Sleep Onset (WASO)
Wake time after sleep onset (WASO) will be assessed using a daily sleep diary. WASO is defined as the total amount of time spent awake after initially falling asleep and before final awakening. Weekly average WASO will be calculated for outcome analysis.
Time frame: Baseline and during the 8-week intervention period
Total Sleep Time (TST)
Total sleep time (TST) will be assessed using a daily sleep diary. TST is defined as the total amount of time spent asleep during the sleep period. Weekly average TST will be calculated for outcome analysis.
Time frame: Baseline and during the 8-week intervention period
Sleep Efficiency (SE%)
Sleep efficiency (SE%) will be assessed using a daily sleep diary and calculated as the percentage of time spent asleep relative to time spent in bed. Weekly average sleep efficiency will be calculated for outcome analysis.
Time frame: Baseline and during the 8-week intervention period
Visual Analogue Scale (VAS) for Tinnitus Loudness
Subjective tinnitus loudness will be assessed using a 10-cm visual analogue scale ranging from 0 ("no tinnitus") to 10 ("extremely loud tinnitus").
Time frame: 1 month, 2 months, 3 months, and 5 month from baseline
Hospital Anxiety and Depression Scale (HADS)
The Hospital Anxiety and Depression Scale (HADS) is a 14-item self-report questionnaire comprising two subscales: HADS-Anxiety (HADS-A) and HADS-Depression (HADS-D). Each subscale contains seven items scored from 0 to 3, with scores ranging from 0 to 21.
Time frame: 1 month, 2 months, 3 months, and 5 month from baseline
Dysfunctional Beliefs and Attitudes About Sleep Scale (DBAS)
The Dysfunctional Beliefs and Attitudes About Sleep Scale (DBAS) assesses maladaptive beliefs and attitudes regarding sleep, including rigid beliefs about required sleep duration, misconceptions regarding insomnia, and excessive concern about sleep. Higher scores indicate greater endorsement of dysfunctional sleep-related cognitions.
Time frame: 1 month, 2 months, 3 months, and 5 month from baseline
