Clinical Trial Summary

There is evidence that CBT for insomnia (CBTi) is an effective treatment for sleep disturbance both as a primary problem and when co-morbid with other health problems, such as chronic pain.

This study will investigate the effectiveness of CBTi as a treatment for tinnitus related insomnia. Tinnitus patients reporting clinically significant insomnia will be offered sleep-specific treatment. Six sessions of CBTi will be offered to one group of patients and 2 sessions standard audiological care (psycho-education and sleep hygiene) will be offered to another group. Both groups will be offered sound enrichment at night. In order to take account of the possible effects of clinical contact a third group will be offered 6 sessions of support without a focused tinnitus or sleep intervention. Accepted measures of sleep disturbance will be used as well as measures of tinnitus complaint.

All treatment/contact will be provided at the Royal National Throat Nose & Ear Hospital. Participants will be involved in the study (inc. baseline period {2 weeks}, intervention {8 weeks} and follow-ups {4 and 20 weeks}) for 34 weeks.

Outcome

Type Measure Description Time frame Safety issue
Primary Change in Insomnia Severity Index (ISI) score 7-item questionnaire, each item rates 0 - 4. Total scores range from 0-28 with higher scores indicating more severity. At first and last treatment sessions and at 1 and 6 month follow-ups
Primary Change in the amount of sleep obtained Average of all of the following metrics obtained from 2 weeks of sleep diary measure:
Sleep Onset Latency - lower score indicates better sleep; Wake Time After Sleep Onset - lower score indicate better sleep; Number of night time awakenings - lower scores indicate better sleep; Total Sleep Time - higher scores indicate better sleep; Time in Bed - included only so that Sleep Efficiency can be calculated: Sleep Efficiency (Total Sleep Time / Time in Bed x 100) - higher scores indicate better sleep.
Diary measures for sleep quality (0= worst possible to 10=best possible), tinnitus annoyance (0= not at all to 10= extremely), refreshed at waking (0= not at all to 10= very refreshed) and quality of day time functioning (0= very poor to 10= very good).
A 2-week sleep diary will be kept 2 weeks prior to the first and last treatment sessions and to the 1 and 6 month follow-ups.
Secondary Change in Pittsburgh Sleep Quality Index score 10-item questionnaire. Sum of 7 components; global score range 0 - 21; higher scores indicate worse sleep quality. At first and last treatment sessions and at 1 and 6 month follow-ups
Secondary Change in Dysfunctional Beliefs and Attitudes About Sleep Questionnaire - abbreviated version (DBAS-16) score 16-item questionnaire scored on a 0-10 scale. The average score is calculated from all individual scores and ranges from 0-10; higher scores indicate more dysfunctional / unrealistic beliefs about / sleep. At first and last treatment sessions and at 1 and 6 month follow-ups
Secondary Change in Tinnitus Catastrophizing Scale score 13-item questionnaire scored on a 0-4 scale. Total sum of scores range from 0 - 52. Higher scores indicate higher levels of catastrophizing. At first and last treatment sessions and at 1 and 6 month follow-ups
Secondary Mini Tinnitus Questionnaire score Construct: Tinnitus complaint 12-item questionnaire scored on a 0 - 2 scale. Total sum of scores range 0-24. Higher scores indicate presence of tinnitus. A score of 8 or more indicates the presence of a clinical level of tinnitus-related distress. Screening
Secondary Change in the Tinnitus Questionnaire score Construct: Tinnitus complaint 41-item questionnaire scored on a 0 - 2 scale. Total sum of scores ranges from 0-82; higher scores indicate presence of tinnitus. The reliable change criterion is 11.08. At first and last treatment sessions and at 1 and 6 month follow-ups
Secondary Change in subjective measure of tinnitus loudness Visual Analogue Scale from 0mm to 100mm; higher scores indicate greater loudness of tinnitus. At first and last treatment sessions and at 1 and 6 month follow-ups
Secondary Change in Clinical Outcome in Routine Evaluation - Outcome Measure score Construct: general psychological distress 34-item questionnaire scored on a 0-4 scale. The average of all the scores is calculated and then multiplied by 10, so the scores can range from 0 to 40; a clinical cut-off score is 10 and clinically significant change is 5. At first and last treatment sessions and at 1 and 6 month follow-ups
Secondary Change in Patient Health Questionnaire-9 score Construct: Depression 9-item questionnaire scored on a 0-3 scale; total sum of scores ranges from 0-27 with higher scores indicate greater depression severity. At first and last treatment sessions and at 1 and 6 month follow-ups
Secondary Change in Generalized Anxiety Disorder Assessment-7 score 7-items questionnaire scored on a 0-3 scale; total sum of scores ranges from total score range: 0-21 with higher score indicating more severe anxiety. At first and last treatment sessions and at 1 and 6 month follow-ups

The EQ-5D questionnaire also includes a Visual Analogue Scale (VAS), by which respondents can report their perceived health status with a grade ranging from 0 (the worst possible health status) to 100 (the best possible health status). At first and last treatment sessions and at 1 and 6 month follow-ups
Secondary Change in Work and Social Adjustment Scale score Construct: impaired functioning 5-item questionnaire scored on a 0-8 scale; total sums of scores range from 0-40 with higher scores indicating greater functional impairment.
