A converging body of clinical and empirical reports indicates that autism features elevated rates of paranoia comparable to those of individuals with paranoid schizophrenia. However, the distinct developmental courses and symptom manifestations of these two disorders suggest that the nature of paranoid ideation may differ between them in important and meaningful ways. To evaluate this hypothesi...

Individuals with personality disorders (especially paranoid personality disorder) tend to be reluctant to engage in treatment. This paper aimed to elucidate the role of personality disorder in predicting engagement with psychological treatment for depression. The Outcomes of Depression International Network (ODIN) involves six urban and three rural study sites throughout Europe at which cases o...

Information in the environment is frequently ambiguous in meaning. Emotional ambiguity, such as the stare of a stranger, or the scream of a child, encompasses possible good or bad emotional consequences. Those with elevated vulnerability to affective disorders tend to interpret such material more negatively than those without, a phenomenon known as "negative interpretation bias." In this study ...

A variety of psychological mechanisms have been implicated in their cause, including a tendency to jump to conclusions, an impairment in the ability to understand the mental states of other people (theory of mind), an abnormal anticipation of threat, and an abnormal explanatory style coupled with low self-esteem....

In this article an inpatient case of The Mental Hospital in Zurawica was described, in which first qualitative disorders of consciousness, later a paranoid syndrome and a depressive syndrome preceded diagnosis of Lyme Borreliosis. After the therapy that was applied we observed residual organic mood disorders in the patient. Below, authors demonstrate one of the many clinical situations, where t...

Certain Personality Disorders (PDs) have been found to be present in the prodromal phase of schizophrenia at a higher rate than other personality disorders. Although schizotypal, paranoid, and schizoid PDs are traditionally viewed as spectra for schizophrenia, research suggests that avoidant PD should be included in this group (e.g., Fogelson et al., 2007). The present study examines whether a ...

Central to psychotic disorders, delusions are associated with disability and often respond inadequately to pharmacotherapy. Cognitive-behavioral treatments have been developed over the last 20 years that successfully address delusions. However, meta-analyses suggest only a modest improvement in psychotic symptoms. Because delusions share considerable overlap with anxiety, adapting principles an...

BACKGROUND Psychotic phenomena appear to form a continuum with normal experience and beliefs, and may build on common emotional interpersonal concerns. AIMS We tested predictions that paranoid ideation is exponentially distributed and hierarchically arranged in the general population, and that persecutory ideas build on more common cognitions of mistrust, interpersonal sensitivity and ideas o...
