Abstract Background  Research on emotion regulation and paranoid ideation has mostly focused on isolated regulation strategies and has remained largely inconclusive. According to the emotion regulation model by Berking and Whitley (in: Affect Regulation Training, Springer, New York 2014) successful modification or acceptance/tolerance of emotions requires an adequate comprehension (awareness, clarity, understanding) of emotions and adequate self-support. Method  Building on this model, we investigated whether comprehension and self-support strengthen the negative association between modification and acceptance/tolerance and paranoid ideation. In study 1, we examined the hypotheses crosssectionally based on questionnaire data from a combined sample (N = 125) consisting of people with a psychotic disorder, people at risk of developing psychosis, and healthy controls. In study 2, we examined the same hypotheses longitudinally by employing the experience sampling method in people with clinically relevant psychopathology below diagnostic threshold (N = 138). Results  In study 1, the association between modification and paranoid ideation was not moderated by comprehension or self-support. However, comprehension and self-support moderated the association between acceptance/tolerance and paranoid ideation. In study 2, the interaction effect between comprehension and acceptance/tolerance on paranoid ideation was confirmed. Conclusion  The results indicate that comprehending and accepting/tolerating emotions could be protective against paranoid ideation.

(2001) postulated that negative affect has a crucial influence on the interpretation of internal and external experiences and thereby significantly contributes to paranoid ideation. In support of this model, elevated levels of negative affect have been found to predict paranoid ideation in longitudinal studies (Fowler et al. 2012; Freeman et al. 2012; Lincoln et al. 2017a) and in studies based on the experience sampling Electronic supplementary material  The online version of this article (https​://doi.org/10.1007/s1060​8-020-10173​-6) contains supplementary material, which is available to authorized users. * Martin F.
