Why These Terms Matter for Families
Mental health conversations at home often stall not because families don't care, but because the vocabulary feels clinical and unfamiliar. When a school counselor mentions cognitive distortions or a therapist discusses a child's emotional regulation, parents may nod along without fully understanding what is being described — and that gap can make it harder to reinforce progress at home.
This reference is designed to close that gap. The terms below are among the most commonly used in child and family mental health settings. Familiarity with them won't replace professional guidance, but it can help parents ask better questions, understand reports and treatment summaries, and hold more meaningful conversations with their children.
For practical guidance on how to use this vocabulary in real conversations, see how to talk to kids about mental health. And if you're looking for a broader family wellness framework, this glossary is part of a comprehensive family mental wellness resource.

Key Mental Health Terms, Defined Plainly
The glossary below covers the terms parents are most likely to encounter in school communications, therapy sessions, and pediatric visits. Each definition is written for a general audience — no clinical training required.
Many of these concepts overlap. For instance, recognizing a cognitive distortion is itself a form of improving emotional regulation, and building resilience often involves practicing stronger coping strategies. Understanding how these ideas connect helps families see mental wellness as an integrated, learnable set of skills rather than a fixed trait some children are born with and others aren't. For a family-friendly introduction to one of the most well-supported practices, explore mindfulness without the jargon.
