About

This study aims to develop a smartphone app based on mindfulness-based interventions and test its effectiveness in parents of children with ASD. This study aims:

1. To establish the relationship between different life events, cognitive appraisal, and the psychological distress between parents of children with autism spectrum disorder (ASD);
2. To demonstrate the relationship between parents' cognitive appraisal of life events and psychological distress moderated by mindfulness;
3. To examine the effectiveness of mindfulness-based intervention (MBI) via ecological momentary intervention (EMI) in reducing the psychological distress of parents of children with ASD;
4. To calculate the cost-effectiveness of MBI via EMI in reducing the psychological distress of parents of children with ASD.

Full description

Existing studies have unequivocally demonstrated that parents of children with autism spectrum disorder (ASD) experience various daily life events and suffer from psychological distress. Mindfulness-based intervention (MBI) was found to be an effective buffer between parents' appraisal of life events and psychological distress. However, the mechanism behind the effectiveness was unclear, and traditional MBI in experimental settings were not tailored to personal real-life needs. This study proposed to conduct a randomized controlled trial (RCT) to examine the effectiveness and cost-effectiveness of MBI in the platform of ecological momentary intervention (EMI) in changing participants' cognitive appraisal of daily life events and reducing the psychological distress of parents of children with ASD.

This study aims to answer four research questions:

1. What's the relationship between participants' cognitive appraisal of their life events and psychological distress?
2. Will an increased level of mindfulness moderate the relationship between participants' cognitive appraisal of life events and psychological distress?
3. Will the participants who received MBI via EMI report significantly lower levels of psychological distress compared with those who did not?
4. Will the MBI via EMI be a more cost-effective option compared with the control group?

The proposed study will recruit 526 parents of children with ASD and randomly assign them into the intervention and control groups (263 in each group). Participants in the intervention group will install the EMI app on their smartphone. In the app, participants can browse different mindfulness exercises in the intervention bank at any time, talk to a virtual counselor and receive tailored mindfulness practice daily, practice formal mindfulness exercise every week, complete ecological momentary assessments on the cognitive appraisal of life events and receive a daily log of change of psychological status. Participants in the control group will only receive standardized mindfulness practice instructions 3 times/week. The effects of MBI will be assessed at the end of the intervention and at the 2-month follow-up.

The primary outcome will be participants' psychological distress measured by the depression anxiety stress scale. The secondary outcomes will include participants' subjective well-being, measured by the satisfaction with life scale, level of resilience measured by the psychological empowerment scale and the feasibility and acceptability of the EMI, measured by the treatment acceptability and adherence scale.

The potential benefit of the proposed study is to increase psychological well-being of parents of children with ASD and the method may extend to other participants in the future.

Trial design

Primary purpose: Supportive Care

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Double Blind

---

526 participants in 2 patient groups

Intervention group

Experimental group

Description:

The intervention group will receive a combination of (1) a time-based system-triggered EMI, which will collect participants' sources and status of depression, anxiety and depression in daily life and provide instructions (audios and videos) on mindfulness practice, and (2) a longitudinal survey in parents of children with ASD. The participants will first complete a baseline questionnaire, and then participate in EMI via a smartphone application (App) for 8 consecutive weeks and receive the exercise prompts daily. The EMI will include questions of the self-reported feelings of depression, anxiety and depression. After the 8-week EMI, the participants will be invited to complete a post-experimental survey with similar questions in the baseline questionnaire. Two months after completing the EMI, participants will be contacted to complete a telephone follow-up survey with similar questions in the baseline questionnaire.

Treatment:

Behavioral: Ecological assessment and intervention

Control group

Active Comparator group

Description:

The control group will receive the longitudinal survey exactly the same as the intervention group and 8-week mindfulness-based short-messages sent by the research team on a daily basis. The messages will contain instructions of mindfulness-based practice which will be the same as the intervention group.

Treatment:

Behavioral: Audio-based Mindfulness intervention
