Figures in parentheses are percentages. Compl. reports, percentage of completed reports; NA, negative affect; Time invariant, the time series did not demonstrate a structural change of time (fluctuations over time may have been present); other, model could not be fitted or interpreted; ADM, assigned to the antidepressant medication continuation arm of the trial; PCT + ADM, assigned to the antidepressant medication continuation in combination with preventive cognitive therapy arm of the trial; PCT – ADM, assigned to the arm of the trial that combines preventive cognitive therapy with tapering of antidepressant medication; at the start, relapse during the first 4 weeks of the ESM study period; soon after, relapse at the end of or within 3 weeks after the ESM study period.

One individual (patient 14) displayed both decreased negative affect and negative affective inertia.

One individual (patient 26) experienced increased negative affect and decreased negative affective inertia.

One individual (patient 39) demonstrated decreased negative affect while the analyses could not be interpreted in terms of invariant or changing inertia. Because of particular patients (superscripts a + b + c), not all rows add up to 100%. Details on analyses per individual can be found in the supplemental materials.
