Eksperimentel: EMI group
In addition to completing ecological momentary assessments (EMAs) survey, the EMI group will receive prompts to practice slow-paced breathing during the 2-week trial period.
After completing each EMA core survey, the mHealth platform will automatically analyze the EMA data and notify participants who reported high negative affect (mean score ≥ 3) to voluntarily slow down their breathing rate.
Specifically, participants will be required to breathe at a rate of 6 respiratory cycles per minute, using nasal breathing, with a 1: 1 ratio of inspiratory: expiratory duration.
During each practice, the participants will be instructed to assume a relaxed position, close their eyes, and passively ignore distracting thoughts while engaging in repetitive breathing exercises for 3 min each.
|
The EMA core survey measures seven negative affect (e.g., irritated, sad, ruminating) and six positive affect (e.g., cheerful, relaxed, content).
Response options for these items are on a 7-point scale.
The application will program to send out these core items 5 times per day.

Aktiv komparator: EMA control group
The control group (EMA group) will follow the EMA data collection procedure as same as EMI intervention group but will not receive any feedback via the app.
The EMA group is included in this trial to investigate reactivity and whether completing mobile assessments alone (without slow breathing-prompt feedback) will affect the mental health status of participants.

Tidsramme |

|
Positive and negative affect
Tidsramme: Five times per day during the 2-week trial period.
|
Positive affect (PA) subscale will be calculated by averaging the PA items (items: at this moment I feel satisfied, relaxed, cheerful, energetic, enthusiastic, and calm), and a negative affect (NA) subscale will be calculated by averaging the NA items (items: at this moment I feel upset, irritated, listless/apathic, down, nervous, bored, anxious).
All ratings will use a 7-point Likert scale, where 1 means not at all and 7 means very much.

Depression
Tidsramme: Baseline, 2-week post-intervention, 1-month follow-up
|
This will be assessed by the Chinese version of the Beck Depression Inventory-II (BDI-II).
The BDI-II is a 21-item self-report inventory designed to assess the presence and severity of depressive symptoms.
Each item is rated on a 4-point Likert scale ranging from 0 to 3, based on the severity in the last two weeks.
The total score ranges from 0 to 63, with higher scores indicating more severe depressive symptoms.

Baseline, 2-week post-intervention, 1-month follow-up
|
|
Anxiety
Tidsramme: Baseline, 2-week post-intervention, 1-month follow-up
|
This will be assessed by the Chinese version of the Beck Anxiety Inventory (BAI).
The BAI is a 21-item self-report questionnaire that asks about common symptoms of anxiety, such as feeling nervous, scared, and fear of dying, and was designed to distinguish anxiety symptoms from depressive symptoms.
Each item is rated on a 4-point Likert scale for symptom severity in the past week, ranging from 0 (not at all) to 3 (severely).
The range of total scores is from 0 to 63, with higher scores suggesting greater degrees of anxiety.

Baseline, 2-week post-intervention, 1-month follow-up
|

Stress
Tidsramme: Baseline, 2-week post-intervention, 1-month follow-up
|
This will be assessed by the Chinese version of the Perceived Stress Scale 10-item (PSS-10).
The PSS-10 is a self-report instrument that assesses global stress or how life situations are appraised as unpredictable, uncontrollable, and overloading.
Respondents report the prevalence of an item within the last two weeks on a 5-point scale, ranging from 0 (never) to 4 (very often).
Scoring is completed by reverse scoring four positively worded items (4, 5, 7, and 8) and summing all item scores.
Scale scores range from 0-40, with higher scores indicating higher stress levels.

Sleep quality
Tidsramme: Baseline, 2-week post-intervention, 1-month follow-up
|
This will be measured by the Chinese version of the Pittsburgh Sleep Quality Index (PSQI).
The index consists of a 19-item questionnaire evaluating sleep quality and disturbances over the past two weeks.
The first four items are open questions, whereas items five to 19 are rated on a four-point Likert scale.
Individual item scores yield seven components.
A total score is obtained by adding together the seven component scores.
A higher score indicates poorer sleep quality.

Mindfulness
Tidsramme: Baseline, 2-week post-intervention, 1-month follow-up
|
This will be evaluated by the Chinese version of the Cognitive and Affective Mindfulness Scale-Revised (CAMS-R).
This 12-item scale measures the mindfulness experienced by individuals in four dimensions: attention, present focus, awareness, and acceptance (e.g., "It is easy for me to concentrate on what I am doing," "I am easily distracted").
All the items will be rated using a 4-point Likert scale (1 = rarely/not at all to 4 = almost always).
After reversing the scores of items 2, 6, and 7, higher total scores reflect greater mindfulness qualities.

Heart Rate Variability
Tidsramme: HRV data will be collected during the two-week intervention period while the mobile application (E-Breathing) is in use.
|
Heart rate variability (HRV) will be measured by the Polar H10 Sensor worn by some participants throughout the intervention period.
Stress-response dysfunction is associated with impaired autonomic nervous system activity, as indexed by decreased HRV in stress, anxiety, and depression.
|
HRV data will be collected during the two-week intervention period while the mobile application (E-Breathing) is in use.
