Background. Understanding emotions, stress, and conflicts within the family context is critical for promoting positive change. However, most support services for families often address child development, parenting, couple relationships separately without considering these as interacting systems that contributes to overall family well-being. This project is to evaluate an existing clinical service in York University Psychology Clinic (YUPC), "Building Blocks for Child and Family Well-being" (BBFW), which provides an integrated understanding of the family context, and equips caregivers with tools to help families connect, problem-solve, cope with stress, and thrive. BBFW is a brief virtual program that promotes experiential learning, provides individually tailored strategies, and builds a community of support for caregivers. The current study aims to examine the feasibility, acceptability, and effectiveness of the BBFW program within the York University Psychology Clinic (YUPC), with four objectives:

1. Evaluating the feasibility of implementing the BBWF program into YUPC clinical services, represented by enrolment rates, sample characteristics, retention (i.e., number of sessions attended, % dropout), adherence (i.e., completing in- and out-of-session activities), as well as the acceptability of the program among participants.
2. Examining sample and clinical characteristics of those attending the BBFW service
3. Exploring the effectiveness of the BBFW program through changes in family functioning and meta-emotion philosophy from pre- to post-intervention, as well as changes at 1- and 3-month follow-ups.
4. Evaluating and refining the program quality using participant quantitative and qualitative feedback.

The BBFW program is based on the best evidence from developmental, family, and relationship science. It aims to support family mental health and well-being through a holistic and sustainable approach, viewing the family as a set of multiple, interdependent systems. This program provides a brief, cost-effective, and accessible alternative with the potential to reduce the burden on traditional mental health and support services for Canadian families.
