Track mood alongside activity

Record mood ratings before and after activities to identify what genuinely lifts versus drains you.

Why it works

Depression distorts retrospective mood assessment: people report being miserable all day even when data shows fluctuation. Prospective mood tracking creates an objective record that challenges the cognitive distortion, reveals which activities actually move mood, and provides reinforcement of the scheduling approach when the data confirms it works.

How to do it

1. Rate mood on a simple 1–10 scale at the same times each day (morning, afternoon, evening).
2. Also rate immediately before and immediately after each scheduled pleasant activity.
3. At week’s end, review which activities correlated with positive mood shifts.
4. Shift future scheduling toward highest-effect activities based on the data.

Evidence

Mood-activity monitoring is a standard component of behavioural activation and BA-based self-help; ecological momentary assessment research confirms that activity is a reliable predictor of momentary mood and vice versa. (observational)

Most EMA work is correlational; reverse causation (people do activities when mood is already higher) cannot be fully excluded, though experimental BA designs support the activity-to-mood direction.

Common mistake

Rating mood only once per day and globally, which averages out the variation that reveals activity effects — activity-specific before/after ratings are what generate actionable data.
