- Brief Summary
Brief behavioral treatment for insomnia (BBTI) is a new treatment direction for primary and comorbid insomnia; however, its treatment model has not been established in Taiwan. This study aims to establish the BBTI treatment model among insomniacs in Taiwan and to examine the immediate effects of nurse-led BBTI in adults with insomnia complaints. In this assessor-blinded randomized controlled trial, participants will be randomly allocated to the nurse-led BBTI experimental group, or sleep hygiene control group. Measurement outcomes are sleep parameters measured by the Chinese version of Insomnia Severity Index, Chinese version of Pittsburgh sleep quality index, and sleep diary. Questionnaires will be assessed in pretreatment, posttreatment, and one-month follow-up. We hypothesize that adults with insomnia complaints undergoing nurse-led BBTI will experience greater alleviations in sleep in comparison with participants in the sleep hygiene control group.
- Detailed Description
Background: Insomnia, defined as difficulty initiating and maintaining sleep such that it interferes with daytime function, is a common complaint among the general population, which in turn undermine their mood, cognitive functions, and quality of life. Brief behavioral treatment for insomnia (BBTI) is a new treatment direction for primary and comorbid insomnia; however, its treatment model has not been established in Taiwan.
Purposes: To establish the BBTi treatment model among insomniacs in Taiwan and to examine the immediate effects of nurse-led BBTI in adults with insomnia complaints. We hypothesize that adults with insomnia complaints undergoing nurse-led BBTI will experience greater alleviations in sleep in comparison with participants in the sleep hygiene control group.
Methods: This assessor-blinded randomized controlled trial will employ a two-arm parallel-group design. A total of 42 adults with insomnia complaints will be randomly allocated to the nurse-led BBTI, or sleep hygiene control group in a 1:1 ratio. For the nurse-led BBTI group, all participants will experience 4-week nurse-led BBTi via 2 in person and 2 telephone sessions. The contents include sleep hygiene, stimulus control, sleep restriction, and relaxation. For the sleep hygiene control group, they will receive usual care, sleep hygiene education, and weekly LINE contacts. Measurement outcomes are sleep parameters measured by the Chinese version of Insomnia Severity Index, Chinese version of Pittsburgh sleep quality index, and sleep diary. Questionnaires will be assessed in pretreatment, posttreatment, and one-month follow-up. A generalized estimating equation will be used to test research hypotheses.

- Primary Outcome Measures
Name Time Method Changes in Sleep parameters from sleep logs: sleep onset latency(SOL) At baseline, week 1 to 3 (during the intervention), and one month (follow-up) Sleep onset latency(SOL) is the time of duration from lying on bed to fall asleep. SOL shorter than 30 minutes is one of criteria of good sleep condition.
Changes in Sleep parameters from sleep logs: sleep efficiency(SE) At baseline, week 1 to 3 (during the intervention), and one month (follow-up) Sleep efficiency(SE) is the percentage of total sleep time to time in bed. A good sleep condition should meet the criteria of SE greater than 85%.
Changes in Sleep parameters from sleep logs: after sleep onset(WASO) At baseline, week 1 to 3 (during the intervention), and one month (follow-up) Wake after sleep onset(WASO) is the total time of wakefulness after sleep onset. WASO less than 30 minutes is one of criteria of good sleep condition.
Changes in Sleep parameters from sleep logs: total sleep time(TST) At baseline, week 1 to 3 (during the intervention), and one month (follow-up) Total sleep time(TST) is the total time of falling asleep. TST will be used to calculate sleep efficiency(SE).
Changes in Insomnia Severity At baseline, week 5 (after the intervention), and one month (follow-up) Insomnia Severity will be measured by Chinese version Insomnia Severity Index (ISI). ISI has 7 questions to evaluate sleep difficulty. The total score range from 0-28, if score\>7 is associated with insomnia. The higher score means more severe insomnia.
Changes in Sleep quality At baseline, week 5 (after the intervention), and one month (follow-up) Sleep quality will be measured by Pittsburgh Sleep Quality Index (PSQI). PSQI has 18 questions to evaluate sleep condition. The total score range from 0-21, if score\>5 is associated with poor sleep. The higher score means poorer sleep quality.
- Secondary Outcome Measures
Name Time Method Changes in Anxiety At baseline, week 5 (after the intervention), and one month (follow-up) Anxiety will be measured by Depression Anxiety Stress Scale-21 (DASS21). DASS21 has 21 questions to evaluate the state of depression, anxiety, and stress. 7 of the questions are used to measure the severity of anxiety. The total score should be multiplied by 2 range from 0-42, if score\>7 is associated with anxiety. The higher score means more severe anxiety.
Changes in Quality of life At baseline, week 5 (after the intervention), and one month (follow-up) Quality of life will be measured by RAND-36 Health Status Inventory. It has 36 questions to assess eight health concepts including physical functioning, role limitations caused by physical health problems, role limitations caused by emotional problems, social functioning, emotional well-being, energy/fatigue, pain, and general health perceptions.
Changes in Depression At baseline, week 5 (after the intervention), and one month (follow-up) Depression will be measured by Depression Anxiety Stress Scale-21 (DASS21). DASS21 has 21 questions to evaluate the state of depression, anxiety, and stress. 7 of the questions are used to measure the severity of depression. The total score should be multiplied by 2 range from 0-42, if score\>9 is associated with depression. The higher score means more severe depression.
Changes in Stress At baseline, week 5 (after the intervention), and one month (follow-up) Stress will be measured by Depression Anxiety Stress Scale-21 (DASS21). DASS21 has 21 questions to evaluate the state of depression, anxiety, and stress. 7 of the questions are used to measure the severity of stress. The total score should be multiplied by 2 range from 0-42, if score\>14 is associated with anxiety. The higher score means more severe stress.
Changes in Daytime Sleepiness At baseline, week 5 (after the intervention), and one month (follow-up) Daytime Sleepiness will be measured by Epworth Sleepiness Scale (ESS). ESS has 8 questions to evaluate the condition of dozing off or falling asleep. The total score range from 0-24, if score\>10 is associated with daytime sleepiness.
Changes in Fatigue At baseline, week 5 (after the intervention), and one month (follow-up) Stress will be measured by Brief Fatigue Inventory- Taiwan Form (BFI- Taiwan Form). BFI- Taiwan Form has 9 questions to evaluate the state of fatigue. The score of each item range from 0-10, if score\>4 is associated with fatigue. The higher score means more severe fatigue.
