Brief summary
This randomized, open, parallel controlled study aims to explore the clinical effectiveness of smartphone-based digital Cognitive behavioural therapy for insomnia（dCBT-I）. Patients who diagnosed chronic insomnia disorder and proficient in using mobile phone intended to receive CBT-I. Participants will be random allocation into Group dCBT-I and Group Sleep Education. Primary outcome is the insomnia severity as measured using the Insomnia Severity Index (ISI).
Detailed description
This is a single-center, randomized, open, parallel controlled study. Patients who had no CBTI treatment before for chronic insomnia will be recruited and followed for 6 weeks. Participants will be random allocation into Group dCBT-I and Group Sleep Education, and then explore the clinical effectiveness of smartphone-based digital CBT-I therapy. We will collect the baseline information: population characteristics, including age, sex, education, employment, living and residential status, demographic data, smoking and alcohol consumption, body mass index (BMI); medical history and medication status and adverse reactions during treatment. Primary outcome is the Insomnia Severity Index (ISI). Secondary outcomes include an online sleep diary measured information regarding: time in bed(TIB), total sleep time (TST), sleep efficiency (SE), total wake time(TWT); bracelet measured information regarding: total sleep time (TST), sleep latency(SL), sleep efficiency (SE), the times of wake from sleep(TWS), sleep quality score setting by bracelet; the 16-item Dysfunctional Beliefs and Attitudes about Sleep Scale (DBAS-16); Fatigue Severity Scale(FSS); Health-related Quality of Life (SF-12); Generalized Anxiety Disorder Scale-7 (GAD-7); Patient Health Questionnaire-9 (PHQ-9).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Insomnia Severity Index (ISI) | V2 and V4 visit ( 6, 18 weeks after recruitment). | The ISI is a 6-item self-report measure of impairment in daytime functioning due to inadequate sleep. The ISI shows adequate internal consistency, appropriate test-retest reliability, and sensitivity to change with treatment. Scores can range from 0 to 28, with higher scores indicating more impairment. Scores higher than 14 are thought to be indicative of the presence of clinical insomnia and change in scores of 8.4 have been found to reflect moderate improvement in clinical samples. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Sleep characters recorded by smart bracelet | baseline, and 6, 10,18, 30 weeks after recruitment. Some participants 52 weeks after recruitment decided by themselves. | The participants will wear the bracelet everyday at each evaluating time point for at least week before each evaluation/visit. The following parameters recorded by the bracelet will be used for analysis: total sleep time (TST), sleep latency(SL), sleep efficiency (SE), the times of wake from sleep(TWS), sleep quality score setting by bracelet. |
| Dysfunctional Beliefs and Attitudes about sleep scale (DBAS-16) | baseline, and 6, 10,18, 30 weeks after recruitment. Some participants 52 weeks after recruitment decided by themselves. | All items in DBAS-16 will be answered on a 10-point Likert scale ranging from 0 (strongly disagree) to 10 (strongly agree). As emphasized by Morin et al, there is no absolute right or wrong answer for a single item. Rather, the degree to which a particular item is endorsed by a participant is a reflection of the nature of the dysfunction. The mean scores are summed to generate a DBAS-16 overall index and four subscales (consequences, worry/helplessness, expectations, medication), with higher scores reflecting stronger dysfunctional beliefs and attitudes about sleep. |
| Fatigue Severity Scale(FSS) | baseline, and 6, 10,18, 30 weeks after recruitment. Some participants 52 weeks after recruitment decided by themselves. | The scale employs nine items to measure the self-reported impact of fatigue. Responses to individual items are rated on a 7-point Likert scale, ranging from 1 = strongly disagree to 7 = strongly agree. The FSS score is calculated as the mean of all item scores, with a score of C4 indicating abnormal fatigue and a score of C5 indicating severe fatigue. |
| Health-related Quality of Life (SF-12) | baseline, and 6, 10,18, 30 weeks after recruitment. Some participants 52 weeks after recruitment decided by themselves. | The SF-12 derived from the SF-36 and measured Quality of Life with 12 items. It generates a profile of respondents HRQoL across eight domains: physical function (PH), role physical (RP), bodily pain (BP), general health (GH), vitality (V), social function (SF), role emotion (RE), and mental health (MH). Finally, the SF-12 generates a summary of physical functional scores (PCS) and mental functional scores (MCS). The PCS is calculated based on a combination of physical functioning, role physical, bodily pain and general health scores. The MCS is calculated based on a combination of vitality, social functioning, role emotional, and mental health scores. |
| Sleep characters recorded by online sleep diary | baseline, and 6, 10,18, 30 weeks after recruitment. Some participants 52 weeks after recruitment decided by themselves. | Participants will be encouraged to record sleep diaries each day duration the 6-week of intervention. Participants will complete 7-day online sleep diaries at baseline before recruitment, and 1month, 3month and 6month after intervention. The following parameters extracted from the diary will be used for analysis: time in bed(TIB), total sleep time (TST), sleep latency(SL), sleep efficiency (SE), the times of wake from sleep(TWS), self-scored sleep quality. Data suggest that tracking sleep parameters through these diaries can provide a more comprehensive understanding of sleep status. |
| Insomnia Severity Index (ISI) at V3 and V5 visit | V3 and V5 visit ( 10, 30 weeks after recruitment). | The comparisons of ISI between CBT-I and control group at V3 and V5 visit |
| Insomnia Severity Index (ISI) improvement | 6, 10,18, 30 weeks after recruitment. | Comparisons of ISI improvement values, improvement rate, treatment response rate and insomnia remission rate between dCBT-I group and control group |
| Patient Health Questionnaire-9 (PHQ-9) | baseline, and 6, 10,18, 30 weeks after recruitment. | The PHQ-9 is a self-report measure of depression used widely in research and as a screening measure in primary care and hospital settings. |
| Generalized Anxiety Disorder Scale-7 (GAD-7) | baseline, and 6, 10,18, 30 weeks after recruitment. Some participants 52 weeks after recruitment decided by themselves. | The GAD-7 is designed for use in primary care patients. The GAD-7 consists of a self-report questionnaire that allows for the rapid detection of GAD. Subjects will be asked if they are bothered by anxiety related problems over the past two weeks by answering seven items on a 4-point scale. The total scores range from 0 to 21. At a cutoff score of 9, the GAD-7 has a sensitivity of 89 % and a specificity of 82 % for detecting GAD compared with a structured psychiatric interview. |
