Phenomenological characteristics and explanations of unusual perceptual experiences, thoughts and beliefs in a population sample of early adolescents

Representations of hallucinations and dissociation in young adult literature: using literature to challenge stigma about psychosis

This paper explores the role that sensitively portrayed literary representations of hallucinations and dissociation may have in counteracting stigma associated with these experiences. In it, we focus on narratives of young people experiencing hallucinatory and dissociative phenomena in two award-winning, young adult novels: How It Feels to Float by Helena Fox and A Monster Calls by Patrick Ness. We identify and discuss three literary devices in these two novels that promote empathy for the characters and their experiences. The narrative accounts in both novels challenge conceptions of hallucinations and dissociation as unknowable and unrelatable experiences with their empathic portrayals of relatable characters that create comprehensible accounts of adolescents grappling with their sense of reality. Importantly, they highlight the potential role that literature can play in stigma reduction by positively shaping young peoples' understandings of unfamiliar mental health experiences.

Distress factors of voice-hearing in young people and social relating: Exploring a cognitive-interpersonal voice-hearing model

OBJECTIVES

Little is known about the factors that can maintain the distress related to voice-hearing experiences in youth. Building upon understandings developed with adults, this study aimed to explore the associations between negative relating between hearer and voices, persecutory beliefs about voices and voice-related distress in a clinical sample of adolescents. The study also aimed to investigate associations between relating to voices and wider patterns of social relating.

DESIGN

This was an observational, cross-sectional, survey study.

METHODS

Thirty-four young people (age 14-18 years) who were hearing voices completed measures about voices (characteristics, relating and beliefs) and relating to social others (negative relating styles, social connectedness and belongingness). Participants were patients of NHS mental health services. Bivariate correlations explored associations between relating to voices and distress, beliefs about voices and distress, and between relating to voices and social relating variables.

RESULTS

Perceiving the voices as dominant, intrusive, and persecutory and resisting them was significantly associated with distress. Adjusting for loudness and negative content rendered the association between persecutory beliefs and distress non-significant. Fear of separation and of being alone in relation to social others was associated with distancing from voices. Being suspicious, uncommunicative and self-reliant and/or being sadistic and intimidating towards social others was significantly associated with dependence towards the voices. Greater hearer-to-voice dependence was associated with lower perceived social belongingness and connectedness.

CONCLUSIONS

Beliefs about voices being persecutory, dominant, intrusive and resisting voices seem to be significant contributors of distress in young people. In terms of proximity and power, relating to voices and social others appears to be contrasting.

Psychotic-like experiences? Trajectories and typologies of hallucinations and delusions from early adolescence to early adulthood in a population-based sample of Irish youth

OBJECTIVES

Hallucinations and delusions that occur in the absence of a psychotic disorder are common in children and adolescents. Longitudinal phenomenological studies exploring these experiences are notably lacking. The objective of the current paper was to explore the phenomenology and characteristics of hallucinations and delusions from early adolescence to early adulthood.

METHODS

Participants were 17 young people aged 18-21 years from the general population, all of whom had a history of childhood hallucinations and/or delusions. Longitudinal data on the phenomenological characteristics and attributions of reported hallucinatory and delusional phenomena spanning nine years were explored using content analysis.

RESULTS

Hallucinatory and delusional phenomena were transient for two-thirds of the sample. The remaining one-third reported reoccurring hallucinatory and delusional phenomena into early adulthood. In those, two typologies were identified: (1) Paranormal typology and (2) Pathological typology. The former was characterised by hallucinatory and delusional phenomena that were exclusively grounded in subcultural paranormal or spiritual belief systems and not a source of distress. The latter was characterised by delusion-like beliefs that were enmeshed with individuals' mood states and a source of distress. The perceived source, the subcultural context and how young people appraised and integrated their experiences differentiated the Paranormal and Pathological typologies.

CONCLUSIONS

Not all hallucinatory and delusion-like experiences are psychotic-like in nature. To reliably differentiate between pathological and non-pathological hallucinations and delusions, assessments need to explore factors including the phenomenology of individuals' experiences, how people make sense and appraise them, and the subcultural contexts within which they are experienced.

The Strasbourg Visual Scale: A Novel Method to Assess Visual Hallucinations

The experience of oneself in the world is based on sensory afferences, enabling us to reach a first-perspective perception of our environment and to differentiate oneself from the world. Visual hallucinations may arise from a difficulty in differentiating one's own mental imagery from externally-induced perceptions. To specify the relationship between hallucinations and the disorders of the self, we need to understand the mechanisms of hallucinations. However, visual hallucinations are often under reported in individuals with psychosis, who sometimes appear to experience difficulties describing them. We developed the "Strasbourg Visual Scale (SVS)," a novel computerized tool that allows us to explore and capture the subjective experience of visual hallucinations by circumventing the difficulties associated with verbal descriptions. This scale reconstructs the hallucinated image of the participants by presenting distinct physical properties of visual information, step-by-step to help them communicate their internal experience. The strategy that underlies the SVS is to present a sequence of images to the participants whose choice at each step provides a feedback toward re-creating the internal image held by them. The SVS displays simple images on a computer screen that provide choices for the participants. Each step focuses on one physical property of an image, and the successive choices made by the participants help them to progressively build an image close to his/her hallucination, similar to the tools commonly used to generate facial composites. The SVS was constructed based on our knowledge of the visual pathways leading to an integrated perception of our environment. We discuss the rationale for the successive steps of the scale, and to which extent it could complement existing scales.
