ABC context observation sheet

Write objective before, during and after observations in a fictional ABC sheet without inferring a behavioral function from a chart.

Define what you are recording

Each row describes an observed event: what immediately preceded it, the observable action, and what followed. Consequence means a subsequent event; it does not necessarily mean a punishment or a deliberate response.

The fictional example records communication and activity changes around shared materials. It contains no patient stories and should not be used to infer a diagnosis or prescribe an intervention.

Collect the data consistently

  • Record one event per row with an observable description.
  • Separate observed actions from guesses about thoughts or motives.
  • Include relevant setting information in notes and leave unknown events unknown.

How to complete each data sheet column

Use the stated units and distinguish an observed zero from a missing observation.

  • Date: Date of this observation. Use YYYY-MM-DD, for example 2026-10-09. Rows are ordered by date; equal spacing on the graph does not represent elapsed calendar time.
  • Target: Short fictional or de-identified label for the one activity being observed. Use the same target throughout this report; keep its agreed definition in your approved record.
  • Phase: Optional label for the observation conditions, such as Observation A. A change creates a chart marker; it does not demonstrate a treatment effect.
  • Antecedent: Describe what was observed immediately before the event, using factual context rather than an assumed cause.
  • Behavior: Describe the visible or audible action in concrete terms. Avoid diagnoses, intent or subjective labels.
  • Consequence: Describe what happened immediately after the event. Here consequence means the following event; it does not necessarily mean punishment or behavioral function.
  • Notes: Optional observation context or recording limitation. Exclude names, contact details and other identifiable clinical information.

Fictional worked example

These are original fictional observations, not patient records or a treatment recommendation.

Review and interpretation

The grapher retains ABC rows as a narrative table. It deliberately avoids assigning a trend score or an automated function label.

  • An ABC sequence alone does not establish behavioral function.
  • A recorder’s assumptions can affect the narrative.
  • Missing surrounding context can make two similar events look equivalent.

Questions for the clinical team

  • What did the observer actually see or hear?
  • Which surrounding events were not observed?
  • Who will review multiple sources before interpretation?
