Enhancing Mother-Child Ties and Psychosocial Wellness Through Arts: A Mixed Methods Study on Dyadic Expressive Arts-based Intervention for Children With Intellectual Disability and Their Mothers

The caregiving of children with intellectual disability (ID) is intensive and challenging. Caregivers, particularly mothers, are left in a vulnerable and stressful condition. Children with ID may experience difficulties in expressing emotions and may have behavioral or emotional problems. These difficulties impose extra challenges for the parents to understand and interact with their children with ID. Existing intervention programs for families having children with ID primarily focus on problem-and-emotion-focused measures. While strategies focusing on improving parent-child relationships, mother-child communication, and wellness of the dyads are limited.

Expressive arts-based intervention (EXAT) adopts multiple art modalities for achieving therapeutic goals. It can bypass verbal expression and complicated cognitive processing during interactions, and it is also safe, engaging, enjoyable, and empowering. While existing evidence supports the use of arts-based intervention on children and their parents, there is a limited understanding of the application of dyadic EXAT on the mother-child relationship and their wellness.

The main objective of this study is to evaluate the effectiveness of the dyadic Expressive Arts-based Intervention (EXAT) on the psychosocial well-being of mother-child dyads. Primary outcomes include parent-child relationship, parenting stress, and caregiver burnout; secondary outcomes include mother's affect and quality of life; child's mood, emotional expression, behavioral and emotional problems.

This study adopts a mixed-methods design with quantitative, qualitative, and art-based assessment methods. This study is a randomized controlled trial, running for 3 years for evaluating the effectiveness of the dyadic Expressive Arts-based Intervention (EXAT). 154 Chinese mother-child dyads will be randomized into (i) a dyadic EXAT group or (ii) a treatment-as-usual waitlist control group.

Quantitative analysis will be adopted to investigate the effectiveness of the dyadic intervention on the psychosocial outcomes of children with ID and their caregiving mothers. The qualitative component will consist of longitudinal in-depth interviews with mothers to understand the experiences, perceived changes, and factors that facilitate the process. Art-based assessment will also be used to understand the changes in the emotional expression of children with ID. Data collected will be triangulated to provide an integrative evaluation of the effectiveness of the intervention.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Intervention
Participants in the intervention arm will receive Dyadic Expressive Arts Group Therapy as an intervention.
This therapy utilizes different art modalities, such as visual art, music, movement, dance, drama, and writing, as therapeutic means. With multiple sensory stimulations from different art forms, the therapy facilitates communication, expression, perception, and interactions. The therapy consists of 8 weekly 90 minutes sessions, with 3-4 mother-child dyads in each therapy group. Each session will follow the basic structure of Expressive Arts Therapy, including check-in, warm-up, core art-making, sharing, and closure. The following themes related to the mother-child relationship will be included, such as communication, relationship, expression, empathy, interaction, love, gratitude, and connection.
No Intervention: The Treatment-as-usual Waitlist Control Group
Participants in the control group will continue their routine healthcare and social services. Upon completion of the 8-month study period, participants will be invited to a similar intervention group program.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change of Baseline Mothers' Parenting Stress level at 2 months, 5 months, and 8 months
Time Frame: Baseline, Month 2, Month 5, Month 8
The Chinese validated version of the Parenting Stress Index Short-Form will be used to assess the level of parenting stress of the mothers. The index assesses parenting stress in three domains: (i) parental distress, (ii) parent-child dysfunctional interaction, and (iii) difficult child. Higher scores represent higher parenting stress. This index will be filled in by mothers.
Baseline, Month 2, Month 5, Month 8
Change of Baseline Mothers' Burnout level at 2 months, 5 months, and 8 months
Time Frame: Baseline, Month 2, Month 5, Month 8
The Chinese validated version of the client burnout subscale of the Copenhagen Burnout Inventory will be used to assess the level of burnout of the mothers. Higher scores represent higher burnout. This inventory will be filled in by mothers.
Baseline, Month 2, Month 5, Month 8
Change of Baseline Mothers' perceive Parent-Child Relationship at 2 months, 5 months, and 8 months
Time Frame: Baseline, Month 2, Month 5, Month 8
The subscales of parent-child communication and satisfaction with parenting from the Parent-Child Relationship Inventory will be used to assess the mother's perception of the parent-child relationship. Higher scores represent a more positive perception of certain aspects of the parent-child relationship. The research team will undertake the Chinese translation process. This inventory will be filled in by mothers.
Baseline, Month 2, Month 5, Month 8

Measure Description
Time Frame
Change of Baseline Mothers' Quality of Life level at 2 months, 5 months, and 8 months
Time Frame: Baseline, Month 2, Month 5, Month 8
The Hong Kong-Chinese validated version of the WHO Quality of Life Scale brief version will be used to assess the level of quality of life of mothers. Four main domains of Quality of Life will be assessed, including physical, psychological, social relationship, and environmental. Higher scores represent a higher level of quality of life. The scale will be filled in by mothers.
