ATTACH™ Online Platform: Helping Children Vulnerable to Early Adversity

Addressing the impact of early childhood adversity (e.g., family violence, parental depression, and low income) can promote children's mental health and development, giving children the best start in life and reducing societal health inequities. Family violence, depression, and low income undermine parent-child relationship quality linked to mental health and developmental problems in children that tend to persist over the lifespan. Parents' reflective function (RF), i.e., the capacity to understand their own and their child's thoughts, feelings, and mental states, can strengthen parent-child relationships and buffer the negative impacts of early adversity on children. Investigators have developed and tested an effective intervention program called ATTACH™ (Attachment and Child Health) for parents and their preschool-aged children at-risk of early adversity. In research with 90 families, investigators found the intervention significantly improved RF, parent-child relationship quality, and children's mental health and development. When COVID-19 prevented in-person intervention at the same time as demand soared for ATTACH™, investigators developed and pilot tested (n=10) an Online platform or "platform" with our community partners, including parents, to deliver the program virtually. The purpose of the study is to propose an effective implementation hybrid (EIH) Type II study of the ATTACH™ Online platform. Co-primary objectives evaluate clinical intervention effectiveness and implementation strategy feasibility of the ATTACH™ Online platform in naturalistic, real-world settings delivered by community partner agencies serving families affected by early adversity in Alberta.

Methods: This effectiveness-implementation hybrid (EIH) Type II study is an innovative clinical trial comprised of a quasi-experimental design evaluation of the community-agency delivered ATTACH™ Online platform (with measurement pre-intervention, immediately post-intervention, and three months postintervention) as well as an examination of implementation feasibility via Normalization Process Theory. Investigators will work with 100 parents and children (aged newborn to 36 months).

Objective 1: Employing innovative clinical trial quasi-experimental methods, the effectiveness of the ATTACH™ Online platform will be evaluated on: (1a) children's mental health and development (primary outcome), parent-child relationship quality, and parental reflective function (secondary outcomes) immediately and three months after the intervention, (1b) different patient populations (for whom the program works best/worst), and (1c) health professionals' adherence to the clinical intervention protocol via fidelity assessment. For these objectives, investigators will intervene with 100 new families, a sufficiently powered n to detect minimum d=.5 (from pilot data and accounting for attrition) for pre-intervention/post-intervention differences in children's mental health and development.

Objective 2: Using qualitative methods, the feasibility of implementation of the ATTACH™ Online platform will be evaluated via (2a) knowledge of users' (patients/parents, health care professionals, and administrators) perceptions and experiences of the ATTACH™ Online platform, (2b) ATTACH™ Online platform uptake, and (2c) ATTACH™ Online platform implementation benefits, facilitators, barriers, and challenges. For these objectives, investigators will interview knowledge users (patients/parents, health care professionals, and administrators (n≈60)) until data saturation using Normalization Process Theory.

Study Setting： include 10 Alberta agencies (technically 9, as one agency operates two shelters) serving culturally diverse clients (i.e., Caucasian as well as Black, Indigenous, People of Colour; BIPOC) and immigrants affected by family violence, depression, and low-income. The agencies including Brenda Strafford Centre, Catholic Social Services, Children, Families, and Community Services, Central Alberta Women's Emergency Shelter, Discovery House (Women's Shelter), Highbanks, Home Next Door\*, Hull Social Services, Julietta's Place, La Salle Second Stage Shelter, Catholic Social Services and WINGS of Providence.
