“…Notably, depression and anxiety appear to share a number of phenotypic similarities with the negative symptom dimension of schizophrenia. However, anxiety and depression appear to be more strongly associated with the positive factor of schizophrenia than the negative factor ( [Emsley et al, 1999] and [Lysaker et al, 1995]), suggesting that negative symptom schizophrenia reflects a relative deficit in affect that is inconsistent with the experience of anxiety and depression. For example, Drake et al (2004) found that paranoia (a positive symptom) predicted elevated depression in schizophrenia and spectrum disorder patients.…”

Abstract:The neurodevelopmental vulnerability for schizophrenia appears to be expressed across a dynamic continuum of adjustment referred to as schizotypy. This model suggests that nonpsychotic schizotypic individuals should exhibit mild and transient forms of symptoms seen in full-blown schizophrenia. Given that depression and anxiety are reported to be comorbid with schizophrenia, the present study examined the relationship of psychometrically defined schizotypy with symptoms of depression and anxiety in a college student sample (n = 1258). A series of confirmatory factor analyses indicated that a three-factor solution of positive schizotypy, negative schizotypy, and negative affect provided the best solution for self-report measures of schizotypy, anxiety, and depression. As hypothesized, the model indicated that symptoms of depression and anxiety are more strongly associated with the positive-symptom dimension of schizotypy than with the negative-symptom dimension. This is consistent with studies of schizophrenic patients and longitudinal findings that positive-symptom schizotypes are at risk for both mood and non-mood psychotic disorders, while negative-symptom schizotypes appear more specifically at risk for schizophrenia-spectrum disorders. chizotypy | schizophrenia | anxiety | depression | psychology

“…Similarly, Norman and Malla's [19] study shows how, in a longitudinal approach in a group of schizophrenics, the dysphoric phenomenon is consistently correlated to positive symptoms and not with the so-called negative symptoms of schizophrenia. One study by Lysaker et al [20] confirms how dysphoria tends to correlate with the positive symptoms of the schizophrenic disorder, thereby suggesting a poweful reciprocity. Fuentenebro and Berrios [21], in a history-making revision of the 'predelusional state' concept, highligh dysphoria among the phenomena mentioned.…”

The ‘nonunderstandability’ that traditional psychopathology attributes to ‘true’ delusion does not have a clear demarcation line, but, rather, it is a continuum of various delusional experiences. The attention paid to emotional situations and, specifically, to dysphoria, often contributes to making the delusional phenomenon, and, above all, its persistence, more understandable. A positive correlation between productive psychotic symptoms and the dysphoric mood often prevails in delusions with unfavorable prognoses.
