# Advancing family wellbeing through a Massive Online Open Intervention: the LightBEAM program protocol for randomized waitlist control trial {1a}

## TL;DR

The LightBEAM program is a new online mental health intervention for Canadian parents of young children, aiming to improve family wellbeing through accessible digital support.

## Contribution

The study introduces LightBEAM, a scalable MOOI version of the BEAM program, designed to increase accessibility and reach of mental health resources for Canadian families.

## Key findings

- The LightBEAM program includes 12 weeks of parenting and mental health content, a group forum, and weekly exercises.
- Multilevel modeling and mediation models will assess changes in mental health scores over 12 weeks and a 6-month follow-up.
- Post-program focus groups will evaluate the program's feasibility and acceptability.

## Abstract

While early childhood remains a formative period for healthy child development, it is simultaneously a time when parents experience increased mental health challenges. Such increased challenges (e.g., heightened parental stress, anxiety, depression, etc.) can lead to a variety of adverse child outcomes, including increased risk of externalizing and internalizing disorders. Despite the well-documented effects of parental mental health on child development, Canadian families face a plethora of barriers to accessing services in a timely manner, and as such, low-barrier, accessible mental health supports are needed. In an effort to increase available services to Canadian families, the current study translates the BEAM program (Building Emotional Awareness and Mental Health; thebeamprogram.com), a previously established online parenting and mental health app, into LightBEAM a massive open online intervention (MOOI). By translating an efficacious intervention into a MOOI format, we hope to increase accessibility, scalability, and reach of the program in an effort to better support Canadian families. To investigate the efficacy of translating BEAM into LightBEAM, a pilot waitlist control design will be utilized. Canadian families who are parenting a child between the ages of 1.5 and 8 years old and who are experiencing elevated symptoms of parenting stress, anxiety, depression, and/or anger will be recruited. When moving through the intervention arm of the trial, participants will have access to an app that houses 12 weeks of parenting and mental health videos, a group forum, and weekly exercises to reinforce key skills learned. A combination of Multilevel modeling and mediation models will be utilized to assess changes in participants' elevated mental health scores across the 12-week program and the 6-month follow-up period. Additionally, post-program focus groups will be conducted to further explore the feasibility and acceptability of the program. The translation of BEAM into LightBEAM, a national MOOI, has the potential to increase the scalability of this intervention to ensure that Canadian families have access to timely mental health and parenting supports. Results will be used to inform future iterations of the program. This trial was retrospectively registered with ClinicalTrial.gov NCT07026838 on June 10th, 2025{4}.
