Dissociative Disorders01:27

Dissociative Disorders

24
Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.

Dissociative Identity Disorder

19
Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...

Dissociative Amnesia01:21

Dissociative Amnesia

32
Dissociative amnesia is a complex psychological condition that manifests as an inability to recall personal information, often tied to traumatic or stressful events. Unlike general amnesia, individuals with this condition retain the ability to perform routine activities and procedural tasks, such as operating a phone or navigating public transportation, yet experience profound gaps in autobiographical memory. These lapses may encompass significant life events, such as suicide attempts or...

Summary
This summary is machine-generated.

Everyday stress, childhood trauma, loneliness, and marginalization significantly increase dissociation risk in young adults. Machine learning identified distinct risk profiles based on age, highlighting the complex interplay of factors contributing to dissociative experiences.

Area of Science:

  • Psychology
  • Clinical Psychology
  • Developmental Psychology

Background:

  • Dissociation is linked to severe mental health issues, including suicide and self-harm.
  • Adolescents and young adults are disproportionately affected by dissociative experiences.
  • A comprehensive, multi-factorial explanation for increased dissociation risk is lacking.

Purpose of the Study:

  • To investigate the relative influence of five risk factors on dissociation.
  • To develop high-risk profiles for 'felt sense of anomaly' dissociation (FSA-dissociation) using machine learning.
  • To understand the interplay of factors contributing to dissociation in young adults.

Main Methods:

  • Cross-sectional online survey data from 2384 UK-based individuals aged 16-25.
  • Multiple regression analysis to assess the impact of childhood trauma, loneliness, marginalization, socio-economic status, and everyday stress.
  • Machine learning for exploratory high-risk profile generation.

Main Results:

  • Everyday stress, childhood trauma, loneliness, and marginalization were significant predictors of FSA-dissociation.
  • Machine learning revealed complex interactions: younger individuals (16-20) showed risks associated with negative self-concept and depression, while older individuals (21-25) were influenced by anxiety and emotion regulation difficulties.
  • Marginalization and childhood trauma were consistently important across age groups.

Conclusions:

  • Findings underscore the multi-factorial nature of dissociation in young people.
  • Results can inform clinical assessment and targeted prevention strategies.
  • Improving recognition of dissociation in mainstream services is crucial.
