Objectives of Study：

To determine an effective JITAI decision rule to deliver a brief mindfulness intervention depending the current state of stress of caregivers and to examine if the adaptive model of machine learning algorithm generate higher receptivity of the brief intervention than the static and control model at the end of the four weeks.

Exclusion criteria：

The exclusion criteria are 1) having participated in any structured mind-body intervention, cognitive therapy, or structured psychosocial intervention in the 6 months prior to recruitment and 2) having acute psychiatric and medical comorbidities that are potentially life-threatening (e.g. suicidal ideation) or that limit the caregivers participation or adherence (e.g. acute psychosis)

Intervention：

[First phase] In the first phase of the study, participants will be interviewed by our research assistant over the phone with a structural questionnaire in the first day of the study period. Then, they will receive a psycho-education intervention in the first four days. During that period of time, we will also install the wireless ultra-low-power signal system to monitor their stress in their apartment. At the end of the fourth day, the participants will be asked to use the apps we provide for the coming 16 days and they will be given a brief overview of what to expect in the following 16 days of MRT. We will ensure that the sensor system and the EMAs work properly at the end of the first four-day period. In the 16-day MRT (from Day 5 to Day 20), wireless system data will be processed to classify whether the participant’s condition is probably-stressed or probably-not-stressed during each minute of each day. Minutes, stratified by stress classification and time of day, will be randomly allocated to treatment, which involves the delivery of a brief mindfulness intervention prompt or no prompt.

Intervention：

[Second Phase] In the second phase of the proposed study, we will examine the receptivity of the brief mindfulness intervention as we conceptualize the JITAI with six key elements: a distal outcome (stress level), a proximal outcome (engaging in our intervention), decision points (whether the receptivity is high or not), intervention options (whether interventions are delivered or not), tailoring variables (the receptivity), and decision rules. In the first four days, similar to the first phase of the study, participants will be interviewed with a structural questionnaire, then they will receive a four-day psycho-education intervention.

随机方法（请说明由何人用什么方法产生随机序列）：

Randomization Procedure (please state who generates the random number sequence and by what method)：

Minutes, stratified by stress classification and time of day, will be randomly allocated to treatment, which involves the delivery of a brief mindfulness intervention prompt or no prompt. Randomization will only occur if (1) the participant is available (at home and phone battery > 10%); (2) the participant is not overburdened when: (a) he/she has not received an EMA in the last 10 minutes, (b) has not received an intervention prompt in the last hour
