Negative affect: In individuals at the lowest symptom severity level (level 1), negative affect at t-1 predicts negative affect at t. This association between mental states at two subsequent time points becomes stronger (i.e. there is more transfer) with increasing symptom severity level in a dose-response fashion: this association is strongest at the highest symptom severity level (level 4). Similarly, paranoia affect at t-1 predicts negative affect at t, and this association also becomes stronger with increasing symptom severity strength, again suggesting more transfer of mental states with increasing symptom severity. Positive affect at t-1 predicts negative affect at t also with increasing strength, indicating that the lower level of positive affect, the higher the level of negative affect will be, and, given the progressive strength of the association, more transfer of mental states with increasing symptom severity is again suggested.

Positive affect: No significant interaction was found for SCL-symptom severity level and mental states at t-1 predicting mental states at t. This is reflected by the fact that there is no clear increase in strength of associations with increasing severity level.

Paranoia: In individuals at the lowest symptom severity level (level 1), paranoia at t−1 predicts paranoia at t. This association between mental states at two subsequent time points becomes stronger (i.e. there is more transfer) with increasing symptom severity level in a dose-response fashion: this association is strongest at the highest symptom severity level (level 4). Similarly, negative affect at t−1 predicts paranoia at t, and this association also becomes stronger with increasing symptom severity strength, again suggesting more transfer of mental states with increasing symptom severity. Positive affect at t−1 predicts paranoia at t also with increasing strength, indicating that the lower level of positive affect, the higher the level of paranoia will be, and, given the progressive strength of the association, more transfer of mental states with increasing symptom severity is again suggested.
