Mindfulness Intervention for Parents of Children With ASD (MAPASD)

December 3, 2024 updated by: Xiaochen Zhou, The University of Hong Kong

The Mechanism and Effectiveness of Mindfulness-based Intervention for Reducing the Psychological Distress of Parents of Children With Autism Spectrum Disorder: An Ecological Momentary Intervention and Randomized Controlled Trial

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.

Detailed 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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Intervention group
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.
Behavioral: Ecological assessment and intervention
The MBI-EMI app will include five main parts, including virtual counselor, intervention library, weekly mindfulness practice, assessment bank and daily emotion log. In the eight weeks, the virtual counselor will initiate the conversation every day for three times (morning, afternoon and evening) to check the status of the participants. If the participants responded, the virtual counselor would invite the participants to rate their level of depression, stress and anxiety and then recommend appropriate mindfulness practice in the intervention library, such as 3-minute breathing space or mindful eating. The conversation between the virtual counselor and participants will be in the format of menu list and participants can easily choose from different options.
Active Comparator: Control group
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.
Behavioral: Audio-based Mindfulness intervention
The control group will receive audio recordings of how to practice mindfulness at home.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Cognitive Appraisal of Health Scale
Time Frame: right after the intervention
The CAHS scale will be used to measure participants' cognitive appraisal of daily life events. This scale includes 28 items rated from 1 strongly disagree to 5 strongly agree. This scale was developed based on the transactional theory of stress and coping and thus consists of subscales of primary appraisal (threat, challenge, harm/loss and benign/irrelevant) and secondary appraisal. The internal consistency were all greater than .70.
right after the intervention
Cognitive Appraisal of Health Scale
Time Frame: 2 months after the intervention
The CAHS scale will be used to measure participants' cognitive appraisal of daily life events. This scale includes 28 items rated from 1 strongly disagree to 5 strongly agree. This scale was developed based on the transactional theory of stress and coping and thus consists of subscales of primary appraisal (threat, challenge, harm/loss and benign/irrelevant) and secondary appraisal. The internal consistency were all greater than .70.
2 months after the intervention

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
The Depression Anxiety Stress Scale
Time Frame: right after the intervention
DASS is a self-report questionnaire that measures the emotional states of depression, anxiety, and stress. This scale contains 21 questions rated from 0 (did not apply to me at all) to 3 (applied to me very much, or most of the time). There were seven questions for each one sub-scale of stress, depression, and anxiety. This scale showed good reliability (r=0.96 and 0.80 for the depression and anxiety subscales, respectively) and Cronbach's α was high for the three subscales in parents of children with ASD: 0.91 for the stress, 0.87 for anxiety, and 0.94 for depression and 0.92 for total scale. It has also been validated in Hong Kong population.
right after the intervention
Satisfaction with Life Scale
Time Frame: right after the intervention
The SWLS has 5 items scored on a 7-point scale (1 = strongly disagree to 7 = strongly agree) measuring participants' satisfaction with life and has a Cronbach's alpha for internal consistency of .87 and a test-retest correlation of .82. This scale has also been validated in Chinese and Hong Kong population.
right after the intervention
Psychological Empowerment Scale for parents of children with a disability
Time Frame: right after the intervention
It is a 32-item questionnaire on a 5-point scale (1 = strongly disagree to 5 = strongly agree) with four underlying sub-scales: (a) attitudes of control and competence, (b) cognitive appraisals of critical skills and knowledge, (c) formal participation in organizations, and (d) informal participation in social systems and relationships. This scale showed high reliability coefficients (.90-.97).
right after the intervention
The Five Facet Mindfulness Questionnaire (FFMQ)-short version
Time Frame: right after the intervention
will be used to measure participants' level of mindfulness before and after practicing. It includes 15 items measuring the five facets of mindfulness: observing, describing, acting with awareness, non-judging of inner experience and non-reactivity to inner experience. This scale was further validated and yield good convergent validity and internal consistency. The items will be rated using 1 (very rare)-5 (very often) Likert scale with higher score indicate higher level of mindfulness.
