Area of Science:

  • Neuroscience
  • Psychiatry
  • Cognitive Psychology

Background:

  • Lack of illness awareness in schizophrenia is a significant clinical challenge.
  • Potential contributing factors include executive dysfunction and avoidant coping mechanisms.

Purpose of the Study:

  • To investigate the relationship between executive function, coping styles, and illness unawareness in schizophrenia spectrum disorders.
  • To differentiate unawareness of illness, treatment need, and disorder consequences.

Main Methods:

  • 132 individuals with schizophrenia spectrum disorders were assessed for illness awareness using the Scale to Assess Unawareness of Mental Disorder.
  • Coping styles (escape-avoidance, positive reappraisal) and executive functions (Letter Number Sequencing, Wisconsin Card Sorting Test) were evaluated.

  • Statistical analyses included MANCOVA, ANCOVA, and planned comparisons, controlling for age.

    • Main Results:

    • Participants with greater unawareness of symptoms, treatment needs, and consequences demonstrated poorer performance on executive function tests.
    • Individuals unaware of symptoms showed a higher preference for positive reappraisal coping.
    • Those unaware of disorder consequences favored escape-avoidance coping strategies more than partially unaware participants.

    Conclusions:

    • Executive function deficits are strongly associated with lack of illness awareness in schizophrenia.
    • Specific coping styles, such as positive reappraisal and escape-avoidance, are linked to different facets of unawareness.
    • Findings offer insights into the etiology of impaired illness insight in schizophrenia spectrum disorders.
