Studies investigating the relationship between self-esteem and paranoia have specifically focused on self-esteem level, but have neglected the dynamic aspects of self-esteem. In the present article, the authors investigated the relationship between self-esteem and paranoia in two different ways. First, 154 individuals ranging across the continuum in level of paranoia were studied with the Experience Sampling Method (a structured self-assessment diary technique) to assess the association between trait paranoia and level and fluctuation of self-esteem in daily life. Results showed that trait paranoia was associated with both lower levels and higher instability of self-esteem. Second, the temporal relationship between momentary (state) paranoia and self-esteem was investigated in the daily life of these individuals. Results showed that a decrease in self-esteem was associated with an immediate increase in paranoia. The findings indicate that paranoid individuals are not only characterized by a lower level of self-esteem but also by more fluctuations in their self-esteem and that fluctuations in self-esteem predict the degree of subsequent paranoia. These results are consistent with the hypothesis that paranoia is associated with dysfunctional strategies of self-esteem regulation.
OBJECTIVES. The evidence to date for a causal role of emotions in the generation of paranoid symptoms is scarce, mainly because of a lack of studies investigating the longitudinal association between emotional processes and paranoia. The primary aim of this study was to investigate whether momentary emotional experiences (anxiety, depression, anger/irritability) and self-esteem predicted the onset and duration of a paranoid episode. We also studied whether levels of emotional experiences and self-esteem were respectively higher and lower during a paranoid episode. DESIGN. A 1-week, prospective momentary assessment study. METHODS. Data were collected using the experience sampling method, a structured self-assessment diary technique. The sample consisted of 158 individuals who ranged across the paranoia continuum. Participants with a psychotic disorder were recruited from in-patient and out-patient mental health services. Participants without psychotic disorder were sampled from the general population. RESULTS. Specific aspects of emotional experience were implicated in the onset and persistence of paranoid episodes. Both an increase in anxiety and a decrease in self-esteem predicted the onset of paranoid episodes. Cross-sectionally, paranoid episodes were associated with high levels of all negative emotions and low level of self-esteem. Initial intensity of paranoia and depression was associated with longer, and anger/irritability with shorter duration of paranoid episodes. CONCLUSIONS. Paranoid delusionality is driven by negative emotions and reductions in self-esteem, rather than serving an immediate defensive function against these emotions and low self-esteem. Clinicians need to be aware of the central role of emotion-related processes and especially self-esteem in paranoid thinking.
This study revealed no evidence for a generalized hedonic deficit in patients with psychotic spectrum disorders. Lower rather than higher levels of negative symptoms were associated with a pattern of emotional processing which was different from healthy controls.
Paranoid thinking is context dependent in individuals with medium or at-risk levels of trait paranoia. Perceived social threat seems to be context dependent in the low paranoia group. However, at high levels of trait paranoia, momentary paranoia and momentary perceived social threat become autonomous and independent of social reality.
Hypothesized relationships between experiential avoidance (EA), self-esteem, and paranoia were tested using structural equation modeling in a sample of student participants (N = 427). EA in everyday life was also investigated using the Experience Sampling Method in a subsample of students scoring high (N = 17) and low (N = 15) on paranoia. Results showed that paranoid students had lower self-esteem and reported higher levels of EA than nonparanoid participants. The interactive influence of EA and stress predicted negative self-esteem: EA was particularly damaging at high levels of stress. Greater EA and higher social stress independently predicted lower positive self-esteem. Low positive self-esteem predicted engagement in EA. A direct association between EA and paranoia was also found. These results suggest that similar mechanisms may underlie EA and thought suppression. Although people may employ EA to regulate self-esteem, this strategy is maladaptive as it damages self-esteem, incurs cognitive costs, and fosters paranoid thinking.
These results are the first to ecologically validate stress-related psychosis in BPD. However, psychotic reactivity was not limited to expression of paranoia but involved a broader range of psychotic experiences including hallucinations.
Important differences exist in the effect of COMT Val158Met on stress reactivity, which may depend on background risk for psychotic disorder. Differential sensitivity to environmental stress occasioned by COMT Val158Met may be contingent on higher order interactions with genetic variation underlying psychotic disorder.
The consensus definition of remission in schizophrenia defines remission as: a state in which patients have experienced an improvement in core signs and symptoms to the extent that any remaining symptoms are of such low intensity that they no longer interfere significantly with behavior and are below the threshold typically utilized in justifying an initial diagnosis of schizophrenia.
