Description of EMA variables

Negative affect	Mean score of five items (I feel anxious, lonely, down, insecure, and irritated). Each item was rated on a 7‐point Likert scale ranging from 1 (not at all) to 7 (very).
Positive affect	Mean score of four items (I feel cheerful, satisfied, relaxed, and globally feeling well). Each item was rated on a 7‐point Likert scale ranging from 1 (not at all) to 7 (very).
Subtle psychosis expression	Mean score of five items (suspiciousness, being afraid of losing control, racing thoughts, pervasive thoughts, and difficulties to express thoughts). Each item was rated on a 7‐point Likert scale ranging from 1 (not at all) to 7 (very).
Event stress	Participants were asked to rate the most important event since last entry on its pleasantness on a bipolar Likert scale from −3 (very unpleasant) to 3 (very pleasant). Consistent with previous studies 36, ratings from −3 to −1 were considered stressful and scores from 1 to 3 were recoded to 0. For simplification, the score was reversed and very unpleasant events therefore represented the highest score on a scale from 0 to 3.
Social stress	Participants were asked with whom they currently were (e.g., nobody or family). When participants reported to be alone, they were asked to answer the following items: I like to be alone (reversed); I would prefer to have company; and I feel safe alone (reversed). When participants reported to be in company, they were asked the following items: I would prefer to be alone; I find the people I am with pleasant (reversed); I feel safe (reversed); I feel I belong (reversed); and I feel judged. All items were scored on a Likert scale from 1 (not at all) to 7 (very), and the mean score of all items was used to estimate the social stress.
Activity stress	Participants were asked about the activity they participated in just before the beep (e.g., resting, watching TV, and smoking). The mean score of the following items [rated on a 7‐point Likert scale from 1 (not at all) to 7 (very)] was used to calculate an activity stress score: I would prefer doing something else; This activity is difficult for me; and I can do this well (reversed).
Overall stress	Average of event stress, social stress, and activity stress.
