Self-help Lifestyle Medicine for Insomnia

January 7, 2021 updated by: Fiona YY Ho, Chinese University of Hong Kong

Effect of a Self-help Smartphone-based Lifestyle Intervention in Reducing Insomnia Symptoms: A Randomized Controlled Trial

This study will examine the effects of a self-help smartphone-based multi-component lifestyle medicine intervention (LM) for alleviating insomnia symptoms in a Chinese population. Since a range of lifestyle factors are related to the pathogenesis and progression of insomnia, modifying different lifestyle factors simultaneously, such as diet, exercise, stress, and sleep which are empirically supported by previous reviews, may be effective to reduce insomnia symptoms (Reid et al., 2010; Vedaa et al., 2016). Traditional Chinese nutritional values will be integrated into the smartphone application to increase the acceptability towards the intervention. A prevalence study suggested that self-help interventions are preferred due to the potential stigmatization related to mental health interventions and the high cost of mental health services in Hong Kong (Lee, Tsang, & Kwok, 2007). Nonetheless, to date, only limited self-help interventions that target lifestyle medicine for sleep-related problems are available. Through this study, we aimed to promote evidence-based patient care and improve help-seeking behaviors and access to evidence-based lifestyle interventions for insomnia.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study will be a randomized controlled trial on the effects of a self-help smartphone-based multi-component lifestyle medicine intervention for reducing insomnia symptoms in the Chinese population. Prior to all study procedures, eligible participants will be required to complete an online informed consent (with telephone support). Assuming an alpha error of 5%, a beta error rate of 20%, and a between-group effect size of 0.77 for the Insomnia Severity Scale (Ip et al., 2020), the final sample is 28 for both groups. With an estimation of 20% withdrawal, 70 eligible participants will be randomly assigned to either the smartphone-based multi-component lifestyle medicine intervention (LM group) or the waitlist control group (WL group) in a ratio of 1:1.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in the Insomnia Severity Index (ISI)
Time Frame: Baseline, immediately post-intervention, and 1-month post-intervention
ISI is a 7-item scale designed to evaluate perceived insomnia severity. Ratings on the 5-point Likert scale are obtained on the perceived severity of sleep-onset, sleep-maintenance, early morning awakening problems, satisfaction with current sleep pattern, interference with daily functioning, noticeably of impairment attributed to the sleep problem, and level of distress caused by the sleep problem.
Baseline, immediately post-intervention, and 1-month post-intervention

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Self-developed survey
Time Frame: Baseline
The self-developed survey will collect information including demographic information (e.g., age, gender, level of education, working industry, relationship status, and location of residence), substance use, body mass index (BMI), rest-activity pattern, and social rhythms, etc.
Baseline
Change in the Hospital Anxiety and Depression Scale (HADS)
Time Frame: Baseline, immediately post-intervention, and 1-month post-intervention
The HADS, a self-reporting questionnaire used for assessing the level of depressive and anxiety symptoms over the past week on a 4-point scale. The HADS consists of two parts: an anxiety subscale (HADS-A) and a depression subscale (HADS-D), both of which have seven items.
Baseline, immediately post-intervention, and 1-month post-intervention
Change in the Short Form (Six-Dimension) Health Survey (SF-6D)
Time Frame: Baseline, immediately post-intervention, and 1-month post-intervention
SF-6D is a preference-based single index measure of health. A six-digit number represents each SF-6D health state, each digit denotes the level of one of six SF-6D dimensions: physical functioning, role limitation, social functioning, bodily pain, mental health, and vitality.
Baseline, immediately post-intervention, and 1-month post-intervention
Change in the Health-Promoting Lifestyle Profile (HPLP II)
Time Frame: Baseline, immediately post-intervention, and 1-month post-intervention
The 52-item HPLPII is composed of a total scale and six subscales to measure behaviors in the theorized dimensions of health-promoting lifestyle: spiritual growth, interpersonal relations, nutrition, physical activity, health responsibility, and stress management.
Baseline, immediately post-intervention, and 1-month post-intervention
Change in the Sheehan Disability Scale (SDS)
Time Frame: Baseline, immediately post-intervention, and 1-month post-intervention
SDS is a brief, 5-item self-report tool that assesses functional impairment in work/school, social life, and family life.
Baseline, immediately post-intervention, and 1-month post-intervention
Change in the Credibility-Expectancy Questionnaire (CEQ)
Time Frame: Baseline, immediately post-intervention, and 1-month post-intervention
The 6-item CEQ yielded ratings of treatment credibility, acceptability/satisfaction, and expectations for success.
Baseline, immediately post-intervention, and 1-month post-intervention
Change in the Pittsburgh sleep quality index (PSQI)
Time Frame: Baseline, immediately post-intervention, and 1-month post-intervention
Participants' subjective sleep disturbance over the past month will be assessed using PSQI. PSQI consists of 19 self-rating items that can be categorized into seven components, including subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication, and daytime dysfunction. Each component is scored on a 4-point Likert scale (0-3). The sum of the seven components results in a global score of 21. A high score indicates worse sleep quality.
Baseline, immediately post-intervention, and 1-month post-intervention
Change in the Consensus Sleep Diary (CSD-M)
Time Frame: Baseline, immediately post-intervention, and 1-month post-intervention
The standardized sleep diary records sleep time, wake time, perceived sleeping quality, use of hypnotics, etc. on a daily basis. Variables derived from the sleep diary include sleep onset latency (SOL), wake after sleep onset (WASO), total wake time (TWT), total sleep time (TST), sleep efficiency (SE), etc.
Baseline, immediately post-intervention, and 1-month post-intervention
