Understanding Before Intervention

Understanding the principle

Do not rush from observing behaviour to choosing an intervention. First develop the best available understanding of why this behaviour may be happening for this person, in this context, at this time. The quality of any intervention depends on the quality of the understanding beneath it.

Good formulation begins by separating observation, context, information, hypothesis and what we still do not know, so that assumptions do not quietly become facts. It looks across the whole system: cognition, body, development, sensory processing, communication, prediction and experience, relationships, environment and capacity. It asks the child, asks the people who know the child, and looks closely at when things go well. Every intervention then becomes a test of our understanding rather than the end of the process.

In practice, understanding never delays safety; when a child is in danger, adults act first and analyse afterwards. Equally, we avoid analysis paralysis and start with the least intrusive change likely to help. Outcomes must matter to the person, formulation belongs to the child rather than the professional, and when our understanding turns out to be wrong we revise it. Understand, support, observe, learn and adapt is a continuing cycle, not a single assessment.
