Paranoia and beating fantasy: an inquiry into the psychoanalytic theory of paranoia.

Psychoanalytic contributions to the theory of paranoia are reviewed. As a primary problem underlying paranoia, this paper emphasizes the importance of beating fantasy associated with a fragile personality structure rather than the theory of repressed homosexuality. Castration anxiety and homosexual conflict may precipitate paranoia, but all levels of psychosexual development and their corresponding danger situations contribute to the transformed fantasy of persecution and punishment; early infantile narcissism, aggression, and sadomasochism are especially important. Severe preoedipal disturbance has contributed to deficient ego development and oedipal resolution. The failure to negotiate separation-individuation is associated with narcissistic arrest and impaired object relations and testing of reality. Ego integration, identity and sexual identity are unstable. Attempts at undoing, repair, or revenge of traumata and narcissistic injury and the maintenance of ego stability and (narcissistic) object relationship are more fundamental than homosexual object choice or the negative Oedipus complex in the understanding of paranoid psychopathology.

Ethnic differences in subclinical paranoia: an expansion of norms of the paranoia scale.

The Paranoia Scale (PS) was designed to assess subclinical paranoid ideation (A. Fenigstein & P. A. Vanable, 1992). Despite its established validity, the PS has several problems that need to be addressed. There are no normative data on ethnic minority groups such as African Americans, making it difficult to interpret this group's performance on the PS. Data from the present research revealed that African Americans scored higher on the PS than non-Hispanic Whites. However, interpretation of these findings should be tempered as they may reflect other contextual factors such as discrimination and the impact of racism. Implications for using the PS with African Americans and possible explanations for the observed results were discussed.

[Apropos of a misdiagnosed form of paranoia: paranoia of the elderly].

The expression of elements of a paranoid symptomatology (suspicion, mistrust, hostility, etc.) is frequently seen in the elderly patients. Paranoid symptom is non-specific in geronto-psychiatric practice. The association with a cognitive disorder is frequent. The relationship between this trouble and a previous paranoid personality disorder appears, according to literature, looser than in the younger patients. The paranoid behavioral pattern often stands for the elderly as a defense against feelings of inferiority and humiliation. The expression of a paranoid symptomatology is a hamper for the subject's social autonomy, as well as an actual risk factor so far as it may involve a delay in the demands for medical care. Therapeutical attitudes, reassurant and preventing the patient from a rough awareness of his deficit, seem to be useful in the alleviation of the trouble.

The role of subclinical paranoia on social perception and behavior.

The purpose of this study was to investigate the effects of subclinical paranoia on social perception and behavior. Two groups of participants, those high and low in subclinical paranoia, were identified based on extreme scores on the Paranoia Scale (PS). As expected, persons high in subclinical paranoia had greater depression, social anxiety, self-consciousness, and lower self-esteem compared to persons low in subclinical paranoia. In addition, persons high in subclinical paranoia performed worse than persons low in subclinical paranoia on laboratory measures of emotion perception and on an in vivo social perception task. Finally, behavioral differences between these two groups were revealed: Persons high in subclinical paranoia sat further away from the examiner and took longer to read the consent form than low-paranoia persons. These behavioral differences were not due to the group differences in clinical functioning, indicating that level of paranoia generally accounted for these findings.

Confluent paranoia in African American psychiatric patients: an empirical study of Ridley's typology.

This study examined Ridley's (1984) typology of paranoia in African Americans, which assumes orthogonal dimensions of culture and pathology in symptom expression. Median split of scores on the Cultural Mistrust Inventory and the scale of False Beliefs and Perceptions represented high and low levels of cultural paranoia and pathological paranoia, respectively. The 4 groups of Black patients were nonparanoia, cultural paranoia, pathological paranoia, and confluent paranoia. A Fenigstein Paranoia Scale manipulation check indicated that differences in paranoid symptom expression among the groups were partially supportive of Ridley's model, as were measures of perceptions of hostility and self-esteem. Omnibus tests of between-groups differences were significant for global assessment of functioning and number of symptoms recorded in patients' charts. Predicted pattern testing revealed a significant severity dimension in mean scores across paranoia groups for some measures of clinician-rated functioning but not others. SCID interviewers' ratings of cultural mistrust and number of times restrained (or secluded) were more consistent with a pattern representing a cultural dimension than a severity dimension across paranoia groups. Findings provide limited empirical validation of Ridley's typology of paranoia in African Americans.

Clinical features of cocaine-induced paranoia.

OBJECTIVE: The authors' objective was to assess the frequency and nature of cocaine-induced paranoia. METHOD: They interviewed 50 cocaine-dependent men consecutively admitted to a 28-day rehabilitation program. RESULTS: Thirty-four (68%) of the 50 men reported highly distressing transient paranoid states in the context of cocaine use. The men who experienced paranoia did not differ from those who did not in age, race, or measures of cocaine use. The mean duration and amount of cocaine use before development of paranoia of the men who reported paranoia were not significantly different from the mean lifetime duration and amount of cocaine used by the men who did not report paranoia. Paranoia became more severe and developed more rapidly with continued cocaine use. CONCLUSIONS: The transient paranoid state appears to be a common feature of cocaine dependence and does not seem to be simply a result of exceeding a threshold of use. Rather, affected individuals might possess a predisposition to this drug-induced state. The fact that paranoia became more severe and developed more rapidly with continued drug use is consistent with a sensitization model of cocaine-induced paranoia. In vulnerable individuals, limbic sensitization may underlie its expression, but localization to a specific brain region is speculative. Quantity of use and route of administration do not appear directly to predispose to this phenomenon. Future investigations must be aimed at uncovering the markers and meaning of vulnerability to transient paranoia in heavy cocaine users.

Paranoia and emotion perception across the continuum.

OBJECTIVES: Persons with high levels of paranoid ideation may be more sensitive to emotional stimuli, particularly negative emotions, reflecting the operation of a paranoid schema. However, this finding has not been consistently supported and needs further study. This study examined the effect of paranoia, as measured on a continuum, on emotion perception. It was predicted that higher levels of paranoia would be associated with improved emotion perception scores with better recognition for negative emotions than positive. DESIGN: A four-group ANOVA design was used to compare participants with clinical and sub-clinical paranoia to reflect the continuum view of paranoia. METHODS: A group with persecutory delusions (N=30) was compared with three sub-clinical groups (N=88) on two posed emotion perception tasks. The sub-clinical participants were divided into high, moderate, and low groups based on scores from the Paranoia Scale, a widely used measure of sub-clinical paranoia. RESULTS: Persons with persecutory delusions had lower overall emotion perception scores than all of the sub-clinical groups. For negative emotions, persons with persecutory delusions had lower identification scores than the moderate and low sub-clinical groups, but were no different than the high sub-clinical group. Anger was especially problematic for clinical participants. There were no differences for positive emotions. CONCLUSIONS: Instead of an enhanced sensitivity for the recognition of emotional states, higher levels of paranoia were linked to a performance deficit on emotion perception tasks. The deficits in emotion perception may reflect the increased skepticism and scrutiny associated with posed emotion tasks (Davis & Gibson, 2000). Research should begin to focus on the underlying mechanisms of emotion perception deficits in paranoia.

Paranoia in a nonclinical population of college students.

The present study examined the incidence of paranoid ideation in a nonclinical population. A sample of 324 college students completed a questionnaire assessing their personal experiences of paranoia, with an emphasis on the cognitive, behavioral, and affective components of their experience. They also completed a general measure of paranoia in nonclinical samples, the Fenigstein and Vanable Paranoia Scale, and the Rosenberg Self-Esteem Scale. A total of 153 participants reported an experience of paranoia, which included a clear statement of planned intention to harm. This group scored significantly higher on the Paranoia Scale than those who reported no experience of paranoia. Furthermore, greater levels of paranoid ideation were associated with lower self-esteem. The present findings suggest that paranoia is a common human experience, and are consistent with the idea of continuity between normal and abnormal experience.

[The history and psychopathology of paranoia].

The concept of paranoia refers to a main problem of general psychopathology: Paranoia represents the prototype of a pure delusional disorder. The text reviews the descriptive psychopathological and nosological aspects of paranoia which is orientated towards the well-known historical studies by Kraepelin, Gaupp, Kretschmer and Jaspers. The systematic character of the delusional ideas and a specific emotional-affective state connected with a typical (sensitive-vulnerable) personality constitute the "classical" concept of paranoia. Furthermore, the characteristics of paranoia experience and its distinction from delusion during schizophrenic disorders are discussed. The possibility of communication with a delusional person in his autistic world calls for our understanding of the inner and existential meaning of delusion. Therefore the research into the problem of paranoia requires consideration of phenomenological, philosophical and anthropological points of view.

Psychological processes and paranoia: implications for forensic behavioural science.

Paranoid delusions have recently become the focus of empirical research. In this article, we review studies of the psychological mechanisms that might be involved in paranoid thinking and discuss their implications for forensic behaviour science. Paranoia has not been consistently associated with any specific neuropsychological abnormality. However, evidence supports three broad types of mechanism that might be involved in delusional thinking in general and paranoia in particular: anomalous perceptual experiences, abnormal reasoning, and motivational factors. There is some evidence that paranoia may be associated with hearing loss, and good evidence that paranoid patients attend excessively to threatening information. Although general reasoning ability seems to be unaffected, there is strong evidence that a jumping- to-conclusions style of reasoning about data is implicated in delusions in general, but less consistent evidence specifically linking paranoia to impaired theory of mind. Finally, there appears to be a strong association between paranoia and negative self-esteem, and some evidence that attempts to protect self-esteem by attributing negative events to external causes are implicated. Some of these processes have recently been implicated in violent behaviour, and they therefore have the potential to explain the apparent association between paranoid delusions and offending.

The evolution of insight, paranoia and depression during early schizophrenia.

BACKGROUND: How insight, paranoia and depression evolve in relation to each other during and after the first episode of schizophrenia is poorly understood but of clinical importance. METHOD: Serial assessments over 18 months were made using multiple instruments in a consecutive sample of 257 patients with first episode DSM-IV non-affective psychosis. Repeated measures of paranoia, insight, depression and self-esteem were analysed using structural equation modelling, to examine the direction of relationships over time after controlling for confounds. RESULTS: Depression was predicted directly by greater insight, particularly at baseline, and by greater paranoia at every stage of follow-up. Neither relationship was mediated by self-esteem, although there was a weak association of lower self-esteem with greater depression and better insight. Paranoia was not strongly associated with insight. Duration of untreated psychosis and substance use at baseline predicted depression at 18 months. CONCLUSIONS: In first-episode psychosis, good insight predicts depression. Subsequently, paranoia is the strongest predictor. Neither effect is mediated by low self-esteem. Effective treatment of positive symptoms is important in preventing and treating low mood in early schizophrenia.

A haplotype at the DBH locus, associated with low plasma dopamine beta-hydroxylase activity, also associates with cocaine-induced paranoia.

Low levels of dopamine beta-hydroxylase (DbetaH) protein in the plasma or cerebrospinal fluid (CSF) are associated with greater vulnerability to positive psychotic symptoms in several psychiatric disorders. DbetaH level is a stable, genetically controlled trait. DBH, the locus encoding DbetaH protein, is the major quantitative trait locus controlling plasma and CSF DbetaH levels. We therefore hypothesized that DBH variants or haplotypes, associated with low levels of DbetaH in the plasma, would also associate with greater vulnerability to cocaine-induced paranoia. To test this hypothesis, we first showed that a di-allelic variant, DBH*5'-ins/del, located approximately 3 kb 5' to the DBH transcriptional start site, significantly associates with plasma DbetaH activity in European-Americans (n = 66). Linkage disequilibrium analysis of that polymorphism and DBH*444g/a, another di-allelic variant associated with DbetaH levels, demonstrated that alleles of similar association to DbetaH levels are in positive disequilibrium. We then estimated DBH haplotype frequencies in cocaine-dependent European Americans rated for cocaine-induced paranoia (n = 45). As predicted, the low-DbetaH-associated haplotype, Del-a, was significantly more frequent (P = 0.0003) in subjects endorsing cocaine-induced paranoia (n = 29) than in those denying it (n = 16). Comparison to control haplotype frequencies (n = 145 healthy European-Americans) showed that the association predominantly reflected under-representation of Del-a haplotypes in those denying cocaine-induced paranoia. We conclude that: (a) the two DBH polymorphisms we studied are associated with plasma DBH levels; (b) those two polymorphisms are in significant linkage disequilibrium in European Americans, with alleles of similar association to DbetaH levels in positive disequilibrium; and (c) the haplotype associated with low DBH activity is also associated with cocaine-induced paranoia.

Cocaine-induced paranoia and psychosis proneness.

OBJECTIVE: The aim of this study was to determine whether individuals who experience transient cocaine-induced paranoia are vulnerable to psychosis. METHOD: The subjects were 20 cocaine-dependent men who had been using more than 5 g of cocaine per week and were undergoing substance abuse treatment; half reported binge-limited cocaine-induced paranoia. The men were assessed with the Perceptual Aberration Scale and the Magical Ideation Scale, self-report measures of symptoms thought to precede the development of functional psychosis. RESULTS: The combined scores on the Perceptual Aberration Scale and Magical Ideation Scale were strongly correlated with a history of cocaine-induced paranoia. The sensitivity, specificity, and positive and negative predictive power were 80.0%, 90.0%, 88.9%, and 81.8%, respectively. CONCLUSIONS: Heavy cocaine users who experience transient paranoia while intoxicated may be at higher risk for development of psychosis than cocaine users who do not experience paranoia.

Ethnicity/race, paranoia, and hospitalization for mental health problems among men.

OBJECTIVES: I tested the hypothesis that Black men with high levels of distrust (i.e., mild paranoia) are at greater risk of hospitalization for mental health problems than their White counterparts. METHODS: Secondary analysis was conducted of data from a subsample of 180 men in an epidemiological study. Mental health hospitalization was the outcome and ethnicity/race, mild paranoia, and their interaction were main predictors in a logistic regression analysis. The ethnicity/race by mild paranoia interaction tested the study hypothesis. RESULTS: The ethnicity/race by mild paranoia interaction was statistically significant. Contrary to the hypothesis, Black men with mild paranoia were less likely to be hospitalized. CONCLUSIONS: Black men's lack of trust regarding the mental health system may cause them not to seek services. Factors critical to increasing their trust are acknowledgment of racial biases in the mental health system and sincere efforts to eliminate racial disparities in mental health treatment.

Querulous paranoia in Chinese patients: a cultural paradox.

OBJECTIVE: There has been no reported case of querulous paranoia from the Asian population. A prospective study was undertaken to identify patients with querulous paranoia in an outpatient clinic. METHOD: One thousand, five hundred and fifty-one new referrals to a university-affiliated psychiatric outpatient clinic in Hong Kong were screened for querulous paranoia during routine clinical work. RESULTS: Three patients with querulous paranoia (0.19%) were identified during 1 year. The case histories of these three patients are reported. CONCLUSION: Possible reasons for the low reporting rate are discussed and the importance of sociocultural traditions in the development and recognition of querulous paranoia is emphasised.

Paranoia in African-American men receiving inpatient psychiatric treatment.

The present study tested a continuum model of paranoid symptom expression in a sample of African-American men receiving inpatient treatment in a state psychiatric hospital. The continuum measure comprised the scales of Distrust (DST), Perceived Hostility of Others (PHO), and False Beliefs and Perceptions (FBP) from the Psychiatric Epidemiology Research Interview (PERI), reflecting mild to severe paranoia, in the order listed. They were interviewer administered with other self-report symptom measures, within three weeks of hospital admission, by ethnically matched interviewers. A multivariate model with repeated measures for the continuum of paranoia revealed that scores on the PERI paranoia scales correlated similarly with scores on the Fenigstein measure of interpersonal paranoia, but correlated differentially with the Politic/Law subscale of the Cultural Mistrust Inventory, a measure of cultural paranoia. Diagnosis and treatment of African-American men for mental health problems in correctional and inpatient settings should be sensitive to the distinction between clinical and cultural aspects of their experiences.
