“…Most studies employed a cross‐sectional design and relied on self‐report measures of worry. One cross‐sectional study ( N = 150) found that self‐reported rumination was associated with more paranoid thoughts ( r = .33, p < .01) and more delusions ( r = .48, p < .01; Startup et al, 2016). However, these associations were rendered not significant after adjusting for self‐reported worry and anxiety symptoms (Startup et al, 2016).…”

Objectives Accumulating research evidence supports the role of emotion dysregulation in the etiology of schizophrenia spectrum disorders. The present systematic review synthesized the extant literature and aimed to determine the effects of cognitive emotion regulation strategies and global emotion dysregulation on positive and negative symptoms in schizophrenia spectrum disorders. Method A comprehensive systematic review was conducted to identify quantitative studies published between 2000 and 2019. A total of 22 studies were included in this review. Results Overall, maladaptive cognitive emotion regulation strategies of rumination, worry, and suppression were generally related to more positive symptoms, while global emotion dysregulation was related to more positive and negative symptoms. Conclusions Our results provide preliminary and conceptual evidence on the role of emotion dysregulation in understanding schizophrenia spectrum disorders. Psychological treatment should further determine the therapeutic value of addressing emotion dysregulation to improve positive and negative symptoms in schizophrenia spectrum disorders.

“…Cognitive models of paranoia [58][59][60] cite worry and anxiety as maintaining paranoid ideation based on a range of prior evidence. Worry has been found to be present at high levels in highly paranoid people [61], and psychological treatment for worry has been shown to reduce paranoia in a targeted randomized controlled trial [62]. Similarly, induction of stress has been shown to increase state paranoia, mediated by anxiety [6,56], in addition to anxiety predicting higher state paranoia in ambiguous virtual environments [63].…”

Paranoia, sensitization and social inference: findings from two large-scale, multi-round behavioural experiments

The sensitization model suggests that paranoia is explained by over-sensitivity to social threat. However, this has been difficult to test experimentally. We report two preregistered social interaction studies that tested (i) whether paranoia predicted overall attribution and peak attribution of harmful intent and (ii) whether anxiety, interpersonal sensitivity and worry predicted the attribution of harmful intent. In Study 1, we recruited a large general population sample (N = 987) who serially interacted with other participants in multi-round dictator games and matched to fair, partially fair or unfair partners. Participants rated attributions of harmful intent and self-interest after each interaction. In Study 2 (N = 1011), a new sample of participants completed the same procedure and additionally completed measures of anxiety, worry and interpersonal sensitivity. As predicted, prior paranoid ideation was associated with higher and faster overall harmful intent attributions, whereas attributions of self-interest were unaffected, supporting the sensitization model. Contrary to predictions, neither worry, interpersonal sensitivity nor anxiety was associated with harmful intent attributions. In a third exploratory internal meta-analysis, we combined datasets to examine the effect of paranoia on trialby-trial attributional changes when playing fair and unfair dictators. Paranoia was associated with a greater reduction in harmful intent attributions when playing a fair but not unfair

1The sensitisation model suggests paranoia is explained by over-sensitivity to 2 perceived threat in social environments. However, this has been difficult to test 3 experimentally. We report two pre-registered studies that tested i) the sensitisation 4 model as an explanation of paranoia, and; ii) the role of purported maintaining 5 factors in supporting social sensitisation. In study one, we recruited a large general 6 population sample (N=987) who serially interacted with other participants in multi-7round Dictator games, matched to fair, partially fair, or unfair partners. Participants 8 rated attributions of harmful intent and self-interest after each interaction. In study 9 two (N=1011), a new sample of participants completed the same procedure and 10 additionally completed measures of anxiety, worry and interpersonal sensitivity. As 11 predicted, paranoid ideation predicted higher and faster overall harmful intent 12 attributions, whereas attributions of self-interest were unaffected, supporting the 13 sensitisation model. Contrary to predictions, neither worry nor anxiety predicted 14 harmful intent attributions while interpersonal sensitivity predicted decreased harmful 15 intent attributions. In a third exploratory study we combined data sets to examine the 16 effect of paranoia on trial by trial attributional changes when playing fair and unfair 17dictators. Paranoia predicted a greater reduction in harmful intent attributions when 18 playing a fair but not unfair dictator, suggesting paranoia may also exaggerate the 19 volatility of beliefs about the harmful intent of others. 20 21
