Previous evidence suggests paranoia affects people’s functioning in interpersonal relationships. However, less is known about the interconnections among specific aspects of paranoia and domains of social relationships. The goal of the current study was to explore the interplay among different aspects of paranoia, social relationships and negative affectivity (depression, anxiety and social anxiety) in a diverse clinical sample using network analysis. A sample of 366 participants (84.4% female) with a history of mental illness was recruited online. The mean age was 35.31 years. Data were modelled using the Gaussian Graphical Model with regularization. The network included the following scales: R-GPTS, SAD-D, National Institute of Health Toolbox Adult Social Relationship scales, PHQ-9 and GAD-7. The results revealed substantial connections between aspects of paranoia (ideas of reference and ideas of persecution) and both perceived hostility and perceived rejection. Furthermore, significant associations of ideas of reference with social anxiety and loneliness with depression were observed. Perceived rejection and loneliness were the most central nodes in the estimated network. The current study provides robust evidence for the interconnections of paranoia, social relationships and negative affectivity, present across different diagnoses. This further supports the transdiagnostic approach to paranoia research and the related important role of social relationships.
IntroductionThere has been growing interest in the role of attachment mechanisms in the onset and maintenance of paranoia. The latest systematic reviews of mixed samples of healthy individuals and psychiatric patients have revealed that increased trait attachment anxiety and avoidance are associated with experiencing paranoia, with trait attachment anxiety showing a stronger association. Few studies have examined attachment and paranoia in naturalistic conditions via the Experience Sampling Method.ObjectivesThe present study examined whether experiences of attachment anxiety and avoidance fluctuate in the flow of daily life, and whether a within‐person change in both attachment states precedes the experience of momentary paranoia, and negative and positive emotions.MethodsThirty‐seven clinical participants and twenty‐six healthy controls were studied over six consecutive days using the Experience Sampling Method (ESM). An experience‐in‐close‐relationships questionnaire (ECR‐R 16 SF) was used to capture trait attachment dimensions. Several ESM items were used to capture momentary negative and positive affect, paranoia and attachment insecurity states.ResultsThe findings revealed that fluctuations in both attachment insecurity states were significantly higher in the clinical group. A prior elevated attachment anxiety and avoidance was followed by an increase in negative affect in the next moment and elevated attachment avoidance was additionally followed by a decrease in positive affect and an increase in paranoia.ConclusionOur findings reveal the specific temporal associations between momentary attachment insecurity states as predictors of change in emotions/affects and paranoia, along with evidence that state attachment avoidance has a superior impact on momentary affect and paranoia compared to state attachment anxiety. These results contrast with those of recent cross‐sectional studies.
