Anomalous Self-Experiences: Markers of Schizophrenia Vulnerability or Symptoms of Depersonalization Disorder? A Phenomenological Investigation of Two Cases

The DPD case may be characterized only by secondary ASEs and thus better protected against psychotic decompensation than the SPD case, tentatively affected by a combination of primary and secondary A SEs.

Self and world experience in non-affective first episode of psychosis

Disordered Self in the Schizophrenia Spectrum: A Clinical and Research Perspective

Empirical studies support the classic clinical intuition that anomalous self-experiences form a central phenotype of schizophrenia, and outline the phenomenological structures of subjectivity that are needed for grasping the nature of these anomalous experiential phenomena.

Disorders of agency and self in the schizophrenic spectrum

This thesis represents a novel interdisciplinary approach to the study of schizophrenia spectrum conditions by incorporating concepts of self disorder from phenomenology into experimental paradigms and a link from self disorder symptoms to performance in eye movement tasks has been made.

Disturbed Experience of Self: Psychometric Analysis of the Self-Experience Lifetime Frequency Scale (SELF)

The findings of the current study suggest that it is feasible to screen for self-disturbance phenomena in patients with psychotic disorders with the Self-Experience Lifetime Frequency scale (SELF), a validated screener for symptoms of depersonalization complemented by questions covering several other domains of self- Disturbance.

Varieties of Self Disorder: A Bio-Pheno-Social Model of Schizophrenia.

A bio-pheno-social model is preferable to uni-dimensional alternatives to account for distinctive yet varying experiential and neurocognitive abnormalities found in research on schizophrenia, and to integrate these with recent psychosocial and neurobiological findings.

Disordered Self in the Schizophrenia Spectrum

A series of empirical studies targeting self-experience in schizophrenia performed prior to and after the construction of a phenomenologically oriented psychometric instrument for assessing anomalies of self-Experience, the Examination of Anomalous Self-Experience (EASE), support the classic clinical intuition that anomalous self- Experiences form a central phenotype of schizophrenia.



Phenomenology of anomalous self-experience in early schizophrenia.

Detailed clinical phenomenological descriptions of nonpsychotic anomalies of self-experience that may be observable in the prodromal phases of schizophrenia and in the schizotypal disorders are presented.

EASE: Examination of Anomalous Self-Experience

The EASE does not cover all potential anomalies of experience, but focuses only on the disorders of the self, which cannot be used alone as a diagnostic instrument.

Anomalous Self-Experience in Adolescents at Risk of Psychosis

This clinical report describes disorders of self-experience in a small sample of 11 subjects fulfilling the Criteria of Prodromal Syndromes and suggests that the concept of anomalous self-Experience should be further elaborated theoretically as well as empirically.

Schizophrenia, consciousness, and the self.

This article proposes a unifying account emphasizing basic abnormalities of consciousness that underlie and also antecede a disparate assortment of signs and symptoms of schizophrenic symptoms, and introduces the phenomenological approach along with a theoretical account of normal consciousness and self-awareness.

Feeling unreal: 30 cases of DSM-III-R depersonalization disorder.

This study supports the conceptualization of depersonalization disorder as a distinct disorder with a characteristic course that is independent of mood, anxiety, and personality symptoms, and suggests a subtle relationship may exist between childhood trauma and depersonALization disorder that merits further investigation.

Anomalous Subjective Experience among First-Admitted Schizophrenia Spectrum Patients: Empirical Investigation

In this study, 151 consecutive first-admitted patients diagnosed according to the ICD-10, were evaluated on a number of expressive and experiential psychopathological dimensions, with special emphasis on the experiences of perplexity, disorders of self-awareness, perceptual disorders and anomalous bodily experiences.

Negative symptoms, schizophrenia, and the self

Currently, the most prominent way of subtyping schizophrenic symptoms is the distinction between the “positive” and “negative” syndromes (often supplemented by a third group of “disorganization”

A disturbed sense of self in the psychosis prodrome: Linking phenomenology and neurobiology

Looking at the Schizophrenia Spectrum Through the Prism of Self-disorders: An Empirical Study

The assumption that SDs are a discriminant psychopathological feature of the schizophrenia spectrum is supported and their incorporation is suggested to strengthen its construct validity, with potential benefit for both early detection and pathogenetic research.

Feeling unreal: a depersonalization disorder update of 117 cases.

The characteristics of depersonalization disorder found in this sample, the largest described to date, are in good accord with previous literature, and the study highlights the need for novel therapeutic approaches to treat depersonALization disorder.
