An interventional study of Lifestyle Medicine in Psychological Wellbeing, sponsored by Chinese University of Hong Kong. Completed at 1 site in Hong Kong. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2020-03-11.

This study will examine the feasibility and efficacy of lifestyle medicine for the enhancement of psychological wellness in police officers. The integrative lifestyle intervention is based on the "Healthy Body Healthy Mind (HBHM)" programme developed by the University of Melbourne. It includes lifestyle psychoeducation, physical activity, nutrition and diet, relaxation/ mindfulness, and sleep. These components are weaved with psychological elements such as stress management, cognitive restructuring, motivational interviewing, and goal setting strategies that are led by clinical psychologists. While lifestyle medicine has been recognised for centuries a a mean to improve physical health, the field of lifestyle medicine in the context of mental health is still in its infancy. Nevertheless, there is increasing evidence demonstrating the efficacy of individual components of lifestyle medicine (e.g. diet, physical activities, and sleep) on mood and stress management. With a well-researched lifestyle medicine programme adopted from Australia, the research team of the Chinese University of Hong Kong has customised the intervention protocol to fit the Chinese culture, and has conducted a pilot trial to test the protocol across different communities and work populations. The investigators aim to examine the effectiveness of an integration of multiple lifestyle adjustments on psychological wellness from a holistic body-mind perspective. Acknowledging that police officers are one of hte work populations with stressful work nature, it is in a hope that lifestyle medicine would be effective to facilitate stress coping and enhance the psychological wellness of police officers in the long run.

Change in the Patient Health Questionnaire (PHQ-9)
The PHQ-9, a 20-item questionnaire used for screening, diagnosing, monitoring and measuring the severity of depression, which scores each of the nine DSM-IV criteria as "0" (not at all) to "3" (nearly every day). PHQ-9 scores of 5, 10, 15, and 20 represent mild, moderate, moderately severe and severe depression respectively.
Time frame: Baseline, 1-week post-treatment and 12-week post treatment
Change in Depression Anxiety Stress Scales (DASS-21)
DASS-21 is a 21-items scales, comprises three sub-scales which measures the negative emotional states of depression, anxiety, and stress, over the past week. The DASS is based on a dimensional rather than a categorical conception of psychological disorder, thus it has no direct implications for the allocation of patients to discrete diagnostic categories. However, recommended cutoffs for conventional severity labels (normal, moderate, severe) are given in the DASS Manual. Depression Anxiety Stress Normal 0-9 0-7 0-14 Mild 10-13 8-9 15-18 Moderate 14-20 10-14 19-25 Severe 21-27 15-19 26-33 Ex. Severe 28+ 20+ 34+
Time frame: Baseline, 1-week post-treatment and 12-week post treatment
Change in Insomnia Severity Index (ISI)
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. Total score categories: 0-7 indicates no clinically significant insomnia, 8-14 refers to subthreshold insomnia,15-21 represents clinical insomnia (moderate severity), and 22-28 is clinical insomnia (severe).
Time frame: Baseline, 1-week post-treatment and 12-week post treatment
Brief Resilience Scale
The BRS, originally developed by Smith and colleagues (2008), is a 6-item questionnaire rated on a 5-point Likert scale from 1 (strongly disagree) to 5 (strongly agree). Higher scores represent higher level of psychological resilience. The Chinese version of the test validated by Lai \& Yue (2014) has demonstrated good psychometric properties (Cronbach's alpha \> .72) and were comparable to the original version developed by Smith and colleagues. Total score divided by 6 and to be categorized: 1.00-2.99 indicates low resilience; 3.00-4.30 indicates normal resilience and 4.31-5.00 indicated high resilience.
Time frame: Baseline, 1-week post-treatment and 12-week post treatment
Short Form (Six-Dimension) Health Survey (SF-6D)
The 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. The SF-6D index, scores from 0.0 (worst health state) to 1.0 (best health state).
Time frame: Baseline, 1-week post-treatment and 12-week post treatment
Health-Promoting Lifestyle Profile (HPLP II)
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. Items are scored as Never (N) = 1, Sometimes (S)= 2, Often (O) = 3, Routinely (R) = 4 A score for overall health-promoting lifestyle is obtained by calculating a mean of the individual's responses to all 52 items; six subscale scores are obtained similarly by calculating a mean of the responses to subscale items. The use of means rather than sums of scale items is recommended to retain the 1 to 4 metric of item responses and to allow meaningful comparisons of scores across subscales.
Time frame: Baseline, 1-week post-treatment and 12-week post treatment
Change in Sheehan Disability Scale (SDS)
SDS is a brief, 5-item self-report tool that assesses functional impairment in work/school, social life, and family life. Representation of scores in terms of functional impairment: 0: not at all, 1-3: mildly, 4-6: moderately, 7-9: markedly, 10: extremely.
Time frame: Baseline, 1-week post-treatment and 12-week post treatment
Physical activity (Fitbit Surge Fitness Superwatch)
The Fitbit Surge, a commercially available accelerometer-based activity tracker, is used to examine patterns of physical activity and heart rate, objectively.
Time frame: Baseline, 1-week post-treatment and 12-week post treatment
Change in Credibility-Expectancy Questionnaire (CEQ)
The 6-item CEQ yielded ratings of treatment credibility, acceptability/satisfaction, and expectations for success.
Time frame: Baseline, 1-week post-treatment
