Outcome Measures

Primary Outcomes (1)

  • Differences in change from baseline in Pittsburgh sleep quality index (PSQI) scores at the end of treatment in the two groups

    Baseline to week 6

Secondary Outcomes (5)

  • Differences in changes in PSQI scores compared to baseline during follow-up at 3, 6, and 12 months between the two groups

    Baseline to week 6, month 3, month 6, and month 12

  • Differences in the changes in Beck Depression Inventory (BDI) scores from baseline at the end of treatment and follow-up at 3, 6, and 12 months between the two groups

    Baseline to week 6, month 3, month 6, and month 12

  • Differences in Beck Anxiety Inventory (BAI) scores between the two groups at the end of treatment, 3 months, 6 months, and 12 months of follow-up compared to baseline.

    Baseline to week 6, month 3, month 6, and month 12

  • Differences in changes in sleep hygiene awareness and practice scale (SHAPS) between the two groups compared to baseline at the end of treatment, 3 months, 6 months, and 12 months of follow-up [2].

    Baseline to week 6, month 3, month 6, and month 12

  • Differences in changes in the Insomnia Severity Index (ISI) scores between the two groups at the end of treatment, 3 months, 6 months, and 12 months of follow-up compared to baseline.

Interventions

CBTI + tACS group method: CBTI for about 50 minutes each time, for a total of 6 weeks: ① first interview: enrolment assessment; ② second interview: treatment initiation; ③ third interview: sleep titration and sleep hygiene; ④ fourth interview: sleep titration; ⑤ fifth-seventh interview: sleep titration; ⑥ eighth interview: sleep titration (end of standardised CBTI treatment. tACS true stimulation) : Transcranial alternating current therapy (tACS) was operated during the same period of CBTI, with 3 electrodes, placed in the prefrontal lobe and bilateral mastoid; the stimulation intensity was 77.5 Hz, 15 mA, 40 min each time, once a day, 5 days a week, for 6 weeks.

CBTI+tACS

CBTI+sham tACS group method: CBTI treatment method was the same as before. tACS pseudo-stimulation: the electrode placement position, stimulation frequency, and time settings were the same as the real stimulation, and the stimulation process only had the output of gradual rising and falling current at the beginning and the last 10s, respectively, so as to make the subjects produce the same subjective feelings as the real stimulation.
