Dis-sociality (DS) reflects the impairment of social experience in people with schizophrenia; it encompasses both negative features (disorder of attunement, inability to grasp the meaning of social contexts, the vanishing of social shared knowledge) and positive features (a peculiar set of values, ruminations not oriented to reality), reflecting the existential arrangement of people with schizophrenia. DS is grounded on the notion of schizophrenic autism as depicted by continental psychopathology. A rating scale has been developed, providing an experiential phenotype. Here we present the Autism Rating Scale for Schizophrenia – Revised English version (ARSS-Rev), developed on the Italian version of the scale. The scale is provided by a structured interview to facilitate the assessment of the phenomena investigated here. ARSS-Rev is composed of 16 distinctive items grouped into 6 categories: hypo-attunement, invasiveness, emotional flooding, algorithmic conception of sociality, antithetical attitude toward sociality, and idionomia. For each item and category, an accurate description is provided. Different intensities of phenomena are assessed through a Likert scale by rating each item according to its quantitative features (frequency, intensity, impairment, and need for coping). The ARSS-Rev has been able to discriminate patients with remitted schizophrenia from euthymic patients with psychotic bipolar disorder. This instrument may be useful in clinical/research settings to demarcate the boundaries of schizophrenia spectrum disorders from affective psychoses. [ABSTRACT FROM AUTHOR]

Abnormal space experience (ASE) is a common feature of schizophrenia, despite its absence from current diagnostic manuals. Phenomenological psychopathologists have investigated this experiential disturbance, but these studies were typically based on anecdotal evidence from limited clinical interactions. To better understand the nature of ASE in schizophrenia and attempt to validate previous phenomenological accounts, we conducted a qualitative study of 301 people with schizophrenia. Clinical files were analyzed by means of Consensual Qualitative Research, an inductive method for analyzing descriptions of lived experience. Our main findings can be summed up as follows: (1) ASEs are a relevant feature in schizophrenia (70.1% of patients reported at least 1 ASE). (2) ASE in schizophrenia are characterized by 5 main categories of phenomena (listed from more represented to less represented): (a) experiences of strangeness and unfamiliarity (eg "Everything appeared weird. Face distorted, world looks terrible, nasty"); (b) experiences of centrality/invasion of peripersonal space (eg "Handkerchief on scaffolding: message telling him something"); (c) alteration of the quality of things (eg "Buildings leaning down"); (d) alteration of the quality of the environment (eg "Person sitting six feet away seemed to be at an infinite distance"); and (e) itemization and perceptive salience (eg "All patients [in ward] have bright eyes"). (3) ASEs are much more frequent in acute (91.9%) than in chronic (28.15%) schizophrenia patients. Moreover, our findings further empirical support for phenomenological accounts of schizophrenia, including those developed by Jaspers, Binswanger, Minkowski, and Conrad, among others and provide the background for translational research.

Background: Phenomenological psychopathology, through theoretical and idiographic studies, conceptualizes major depressive disorder (MDD) as a disorder of time experience. Investigations on abnormal time experience (ATE) in MDD adopting methodologies requested by the standards of empirical sciences are still lacking. Our study aimed to provide a qualitative analysis, on an empirical ground and on a large scale, of narratives of temporal experiences of persons affected by MDD. Methods: We interviewed 550 consecutive patients affected by affective and schizophrenic disorders. Clinical files were analysed by means of consensual qualitative research. Results: Out of 100 MDD patients, 96 reported at least 1 ATE. The principal categories of ATE are vital retardation- the experience of a stagnation of endogenous vital processes (37 patients), the experience of present and future dominated by the past (29 patients) and the experience of the slackening of the flow of time (25 patients). A comparison with ATE in schizophrenia patients showed that in MDD, unlike in schizophrenia, there is no disarticulation of time experience (disorder of temporal synthesis ) but rather a disorder of conation or inhibition of becoming. Limitations: The interview style was not meant to make a quantitative assessment ("false negatives" cannot be excluded). Conclusions: Our findings confirm the relevance of distinctive features of ATE in MDD, support the hypothesis of an intrinsic disordered temporal structure in depressive symptoms and may have direct implications in clinical practice, especially in relation to differential diagnosis, setting the boundaries between "true" and milder forms of depression and neurobiological research.
