About this study
Official title: Sleep & Stress Test
The study evaluates the improvement of sleep, emotion, and skin by standardizing the use of the blend (Tea Theanine Casein Hydrolysate Pressed Candy, whose active ingredients include Tea Theanine, Casein Hydrolysate, and Saffron Extract).
This is a randomized, double-blind trial for Chinese people aged 20-55. The change of sleep, emotion, skin, and other related indicators of 90 participants after taking Tea Theanine Casein Hydrolysate Pressed Candy, whose active ingredients include tea theanine, casein hydrolysate, and saffron extract, was evaluated through a 28 days product placement test (sub study 1), and the emotional change of 70 participants after taking Tea Theanine Casein Hydrolysate Pressed Candy was evaluated through an EEG test (sub study 2).
Participants who meet the inclusion criteria were randomly assigned to use the experimental product or the placebo control. In sub study 1, 90 participants completed a 7-day baseline period, a 28-day testing period (T1d, T7d, and T28d). In sub study 2, 71 participants completed a single on-site test.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in scores of Pittsburgh Sleep Quality Index, PSQI (28 Days Product Placement Test)
The total score range is 0-21 points. The higher the score, the worse the sleep quality.
Measured: T0 (baseline before consumption), T1wk (after consumption for 1 week), T4wk (after consumption for 4 weeks)
Change in scores of Restorative Sleep Questionnaire Weekly Version (RSQ-W) and Daily Version (RSQ-D) (28 Days Product Placement Test)
The total score is calculated based on the average score of the questionnaire items, and then the average score is converted to a 0-100 scale using the formula: (average score - 1) * 25. The total score ranges from 0 to 100, with higher scores indicating better restorative sleep.
Measured: T0 (baseline before consumption, RSQ-W was used), T1d (after consumption for one day, RSQ-D was used), T1wk (after consumption for one week, RSQ-W was used), T4wk (after consumption for four weeks, RSQ-W was used)
Change in the Fall asleep time, Nighttime sleep duration, Shallow sleep duration, Shallow sleep ratio and Sleep latency (28 Days Product Placement Test)
These indicators were collected by Huawei Smart Band HA580.
Measured: Continuous collection during placement (7-day baseline+28-day product placement test)
Change in the Wakefulness frequency, Sleep quality, Sleepiness in the morning, Refreshment in the morning, mood in the morning, Sleep latency (28 Days Product Placement Test)
The sleep status of participants was tracked through sleep diaries.
Measured: Continuous collection during placement (7-day baseline+28-day product placement test)
Change in the scores of Perceived Stress Scale, PSS-10 (28 Days Product Placement Test)
The total score is calculated based on the cumulative score of the questionnaire items, ranging from 0 to 40 points, with higher scores indicating greater perceived stress.
Measured: T0 (baseline before consumption), T1wk (after consumption for one week), T4wk (after consumption for four weeks)
Change in the scores of The State-Trait Anxiety Inventory, the S-Form, S-AI (28 Days Product Placement Test)
The total score is calculated based on the cumulative score of the questionnaire items, ranging from 20 to 80 points, with higher scores indicating greater anxiety.
Measured: T0 (baseline before consumption), T1d (after consumption for one day), T1wk (after consumption for one week), T4wk (after consumption for four weeks)
Change in the scores of Profile of Mood States, POMS (28 Days Product Placement Test)
The total score is calculated based on the cumulative score of the questionnaire items, ranging from 56 to 216 points. Higher scores indicate stronger negative emotions, reflecting a depressed mood and feelings of irritability.
Measured: T0 (baseline before consumption), T1d (after consumption for one day), T1wk (after consumption for one week), T4wk (after consumption for four weeks)
Change in the Skin tone evenness, Glossiness, ITA°, L, a, b, Dark circles (Under orbital pigmentation area) ITA°, L (28 Days Product Placement Test)
All-face skin images under different light sources were captured by VISIA-CR (CANFIELD, America).
Measured: T0 (baseline before consumption), T1wk (after consumption for 1 week), T4wk (after consumption for 4 weeks)
Change in the Protrusion volume in Eye bag area (28 Days Product Placement Test)
Protrusion volume in Eye bag area was measured by Primos (CANFIELD, America).
Measured: T0 (baseline before consumption), T1wk (after consumption for 1 week), T4wk (after consumption for 4 weeks)
Change in the Skin smoothness, softness, glossiness, hydration, tone evenness, Overall appearance (28 Days Product Placement Test)
Dermatologists score the facial skin condition of participants using validated assessment scales (VAS). Scores for each dimension range from 0 to 9, and higher scores reflect a better skin condition.
Measured: T0 (baseline before consumption), T1wk (after consumption for 1 week), T4wk (after consumption for 4 weeks)
The improvement of dark circles and eye bags (28 Days Product Placement Test)
Dermatologists evaluate the improvement of dark circles and eye bags in participants through baseline and follow-up visit VISIA photos, using an integrated visualization system (IVS) with improved investigator visual score. Each score range from 0 to 3, and higher scores represent a higher level of improvement.
Measured: T1wk (after consumption for 1 week), T4wk (after consumption for 4 weeks)
Change in the scores of Profile of Mood States, POMS (EEG Test)
The sore of tension subscale ranges from 0 to 24 and confusion subscale ranges from 0 to 20, with higher scores indicating greater tension/confusion. The total score is calculated based on the cumulative score of the questionnaire items, ranging from 56 to 216 points. Higher scores indicate stronger negative emotions, reflecting a depressed mood and feelings of irritability.
