Trigger log

Most clients arrive convinced their emotional reactions come out of nowhere. The anxiety just appears. The anger erupts without warning. The low mood drops in mid-afternoon for no reason. The phenomenology is real, the conclusion is wrong. There’s almost always a structure underneath, and a week of structured logging is the fastest way to expose it.

This is the foundational worksheet to run before you assign any cognitive or behavioural intervention. The treatment plan you build is only as good as the formulation, and the formulation runs on real triggers, not the client’s narrative summary of triggers. A week of entries usually surfaces patterns the client genuinely hadn’t connected: specific people, specific times of day, specific sensory inputs, specific cognitions that arrive in sequence with the emotion.

Use it for any case where the formulation is incomplete or where the client’s stated triggers feel too generic to drive the work. New intakes for anxiety where the client says “everything makes me anxious.” Anger cases where the spouse says it comes out of nowhere. Mood cases where the client reports flat weeks but the data shows obvious peaks and dips.

The clinical patterns that emerge across submissions. Time-of-day clusters: most triggers in the late afternoon, or in the hour after waking, points at fatigue, blood-sugar, or anticipatory loops. People clusters: a single name appearing five times in a week is the conversation in session, regardless of what the client tells you about the relationship. Cognitive triggers: the same thought arriving as the antecedent across multiple events points at a hot cognition that the cognitive work then targets directly.

The thing to push on at submission review is granularity. A client logging “work” as the trigger five times is reporting a category, not a trigger. Push for the specific moment within work, the specific person, the specific email, the specific thought that came first. The level of detail is what makes the data clinically useful.

In my-cbt, the worksheet is one of the bundled system templates. Assign it as one of the first homework pieces with a personal message asking the client to log entries close to the moment rather than reconstruct them at the end of the day. Submissions save with timestamps, and you can scan a week of triggers in two minutes before next session, with the patterns usually visible without much analysis.
