BIRP organizes the hour around what happened, not around a diagnosis. Behavior is the client’s presentation and report in this session. Intervention is the specific thing you did: a thought record, a skill rehearsal, a reflection, a scaling question. Response is how the client took that up. Plan is the next session and any between-session step.
An example, with no person attached: Behavior might say the client described a shorter fuse at work and poor sleep. Intervention might say one thought was examined for evidence. Response might say the client named a softer alternative and agreed to try it once. Plan might say review that trial next week. Your real note should follow the shorthand you typed, in the client’s situation, not this sample.
GIRP is the close cousin when the chart leads with the treatment goal, then intervention, response, and plan. Both are on the note writer.
