The goal of this clinical trial is to learn if a virtually-delivered, group-based psychological intervention, called Tuning in to Kids, is feasible and acceptable for parents of children aged 3 to 6 years with congenital heart disease. The main questions this study aims to answer are:

• What do parents of children with congenital heart disease think of the Tuning in to Kids intervention?
• Is the intervention helpful for parents?
• Is the intervention easy for parents to take part in?
• Do the researchers find it easy or difficult to deliver the Tuning in to Kids intervention to parents of children with congenital heart disease?

Participants will:

• Fill out 3 online surveys at home.
• Take part in the Tuning in to Kids intervention (which includes six 90-minute, weekly, online group sessions and two booster sessions) or standard cardiac care.
• Take part in an interview.

Mental health conditions are common among children with congenital heart disease (CHD) and are strongly associated with cardiovascular morbidity and mortality, as well as lower quality of life. Despite increasing awareness, the mental health needs of children with CHD remain largely unmet, especially among those from historically marginalized and underserved communities. To address this gap, this study will test, for the first time in CHD, a virtually-delivered, group-based psychological intervention, called Tuning in to Kids, designed to teach parents how to help their children understand, regulate, and manage their emotions. The intervention includes six, 90-minute, weekly, online group sessions and two 'booster' sessions, coupled with educational resources and home practice activities to improve parent-child interactions, and enhance child emotional and behavioral functioning. Each group is facilitated by two qualified health professionals who are trained in, and certified to deliver, the Tuning in to Kids intervention. In this pilot randomized controlled trial, we will enroll 40 parents (or other primary caregivers) of children aged 3 or 6 years with CHD who underwent surgical intervention in infancy. The primary aim of this study is to assess intervention acceptability and feasibility, and the results generated will directly inform the design of, and provide preliminary data for, a multicenter efficacy trial to examine short- and longer-term intervention effects.

Inclusion Criteria:

1. Child is aged between 3 and 6 years.
2. Child is receiving care from the Cincinnati Children's Heart Institute (at least one cardiology visit in the past 12 months).
