Clinical Trial Summary

This study aims to examine the effectiveness of Tai Chi and conventional exercise in alleviating depressive symptoms in older insomniacs.

Description:

Chinese community-dwelling older adults with mild-to-moderate depressive symptoms and chronic insomnia will be recruited. Eligible participants will be randomized to health education control, Tai Chi or conventional exercise interventions on a 1:1:1 basis after baseline assessment. All interventions will last for 3 months. Outcomes will be assessed at baseline, at 3 months and at 6 months after the completion of the intervention.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Hospital Anxiety and Depression Scale - Depression	The depression score of the Hospital Anxiety and Depression Scale (HADS-D) will be used to evaluate the severity of depressive symptoms. This consists of a seven-item questionnaire with an overall score ranging from 0 to 21. Higher scores are indicative of more severe depressive symptoms.	3 months (post-intervention)
Primary	Hospital Anxiety and Depression Scale - Depression	The depression score of the Hospital Anxiety and Depression Scale (HADS-D) will be used to evaluate the severity of depressive symptoms. This consists of a seven-item questionnaire with an overall score ranging from 0 to 21. Higher scores are indicative of more severe depressive symptoms.	9 months (6 months post-intervention follow-up)
Secondary	Insomnia severity index	The Insomnia Severity Index (ISI) will be used to assess perceived insomnia severity. It consists of a seven-item questionnaire with each item being rated from 0 to 4 on a Likert scale (total score range 0-28). Higher scores are representative of a more severe perception of insomnia.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Pittsburgh Sleep Quality Index	The Pittsburgh Sleep Quality Index (PSQI) will be used to assess subjective sleep quality. It consists of a 19-item questionnaire designed to measure sleep quality and disturbance. The 19 items are grouped into 7 components, and each component yields a score ranging from 0 to 3, with 3 indicating the greatest sleep dysfunction. The total score of the PSQI ranges from 0 to 21, with higher scores indicating worse sleep quality.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Patient Health Questionnaire	The Patient Health Questionnaire (PHQ-9) will be used to assess the severity of depression. The questionnaire is composed of 9 items, with each item being rated from 0 to 3. The PHQ-9 has a total score ranging from 0 to 27, with higher scores suggesting higher depressive symptom severity.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	General Anxiety Disorder Scale	The General Anxiety Disorder Scale (GAD-7) will be used to assess the severity of anxiety. The GAD-7 is composed of 7 items, each being rated from 0 to 3 and with a total score range of 0-21. Higher scores are representative of greater anxiety symptoms.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Hospital Anxiety and Depression Scale - Anxiety	The anxiety score of the Hospital Anxiety and Depression Scale (HADS-A) will be used to assess the severity of anxiety symptoms. The HADS-A consists of a seven-item questionnaire with an overall score ranging from 0 to 21. Higher scores are indicative of greater anxiety symptoms.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Medication usage	The use of medications will be recorded.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	The 12-item Short Form Survey	The 12-item Short Form Survey (SF-12) will be used to measure health-related quality of life. It consists of 12 items that are aggregated to form 2 summary scores: mental component score (MCS) and physical component score (PCS). Both MCS and PCS have a scoring range of 0 to 100, with higher scores indicating better mental and physical functioning.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Short Physical Performance Battery	The Short Physical Performance Battery (SPPB) will be used to assess physical function and balancing performance. The SPPB involves repeated timed chair stands and a 4-meter walk to measure gait speed. Scores ranging from 1 to 4 are assigned based on test results, with higher scores indicating better physical function and balance.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Sleep efficiency through actigraph	Sleep efficiency will be objectively evaluated by means of an actigraph. Sleep efficiency is the ratio between the time spent asleep and the total time spent in bed (expressed as %). Higher rates are indicative of healthier sleep patterns.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Sleep efficiency through sleep diary	Sleep efficiency will be subjectively evaluated by means of a sleep diary. Sleep efficiency is the ratio between the time spent asleep and the total time spent in bed (expressed as %). Higher rates are indicative of healthier sleep patterns.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Wake time after sleep onset through actigraph	Wake time after sleep onset will be objectively measured by means of an actigraph. It represents the total number of minutes that a person is awake after having initially fallen asleep (expressed as minutes). Higher values are indicative of more severe sleep problems.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Wake time after sleep onset through sleep diary	Wake time after sleep onset will be subjectively measured by means of a sleep diary. It represents the total number of minutes that a person is awake after having initially fallen asleep (expressed as minutes). Higher values are indicative of more severe sleep problems.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Number of awakenings through actigraph	The number of awakenings will be objectively measured by means of an actigraph. It represents the total number of times that the participant woke up throughout the night (expressed as N). Higher values indicate worse sleep patterns.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Number of awakenings through sleep diary	The number of awakenings will be subjectively measured by means of a sleep diary. It represents the total number of times that the participant woke up throughout the night (expressed as N). Higher values indicate worse sleep patterns.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Sleep onset latency through actigraph	Sleep onset latency will be objectively measured by means of an actigraph. It represents the time that it takes for a participant to fall asleep and is expressed in minutes. Higher values are indicative of worse sleep patterns.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Sleep onset latency through sleep diary	Sleep onset latency will be subjectively measured by means of a sleep diary. It represents the time that it takes for a participant to fall asleep and is expressed in minutes. Higher values are indicative of worse sleep patterns.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Average awake time through actigraph	Average awake time will be objectively measured by means of an actigraph. It is expressed as wake time after sleep onset divided by the number of awakenings, and is expressed in minutes. Higher values represent worse sleep patterns.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Average awake time through sleep diary	Average awake time will be subjectively measured by means of a sleep diary. It is expressed as wake time after sleep onset divided by the number of awakenings, and is expressed in minutes. Higher values represent worse sleep patterns.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Total sleep time through actigraph	Total sleep time will be objectively measured by means of an actigraph. It represents the total number of minutes spent asleep during the sleep period (expressed as minutes). Higher values are indicative of healthier sleep patterns.	3 months (post-intervention) and 9 months (6 months post-intervention follow-up)
Secondary	Total sleep time through sleep diary	Total sleep time will be subjectively measured by means of a sleep diary. It represents the total number of minutes spent asleep during the sleep period (expressed as minutes).
