- Brief Summary
This study aims to examine the effectiveness of Tai Chi and conventional exercise in alleviating depressive symptoms in older insomniacs.
- Detailed Description
Chinese community-dwelling older adults with mild-to-moderate depressive symptoms and chronic insomnia will be recruited.

- Primary Outcome Measures
Name Time Method Hospital Anxiety and Depression Scale - Depression 9 months (6 months post-intervention follow-up) 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.
- Secondary Outcome Measures
Name Time Method Insomnia severity index 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Patient Health Questionnaire 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Pittsburgh Sleep Quality Index 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Medication usage 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) The use of medications will be recorded.
Sleep efficiency through sleep diary 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Wake time after sleep onset through actigraph 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Number of awakenings through sleep diary 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Sleep onset latency through actigraph 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Average awake time through actigraph 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Number of awakenings through actigraph 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Average awake time through sleep diary 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Total sleep time through actigraph 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Total sleep time through sleep diary 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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). Higher values are indicative of healthier sleep patterns.
General Anxiety Disorder Scale 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
The 12-item Short Form Survey 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Hospital Anxiety and Depression Scale - Anxiety 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Short Physical Performance Battery 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Sleep efficiency through actigraph 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Wake time after sleep onset through sleep diary 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
Sleep onset latency through sleep diary 3 months (post-intervention) and 9 months (6 months post-intervention follow-up) 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.
