The association between the trend in the predicted change in negative mental states (tau) and change in symptom severity from baseline to post in individuals for whom the indicator was correct (N=34, blue) and in the entire sample (N=122, red). Horizontal dotted lines depict the threshold for significant (P<.05) versus non-significant (P>.05) values of tau. For all individuals (dots) above and below these dotted lines (N=65), a change in symptoms was predicted. Negative symptom change implies improvement of psychopathology (i.e., a reduction of symptoms over time). For individuals for whom such improvement was predicted by the indicator, larger reductions in symptoms were related to more pronounced trends in the indicator (i.e. more negative values of tau). Vice versa, individuals for whom symptom worsening was predicted correctly showed a more pronounced indicator (i.e., more positive values of tau) as symptom change increased
