Abstract

Poor insight in schizophrenia is prevalent across cultures and phases of illness. In this review, we examine the recent research on the relationship of insight with behavior, mood and perceived quality of life, on its complex roots, and on the effects of existing and emerging treatments. This research indicates that poor insight predicts poorer treatment adherence and therapeutic alliance, higher symptom severity and more impaired community function, while good insight predicts a higher frequency of depression and demoralization, especially when coupled with stigma and social disadvantage. This research also suggests that poor insight may arise in response to biological, experiential, neuropsychological, social‐cognitive, metacognitive and socio‐political factors. Studies of the effects of existing and developing treatments indicate that they may influence insight. In the context of earlier research and historical models, these findings support an integrative model of poor insight. This model suggests that insight requires the integration of information about changes in internal states, external circumstances, others’ perspectives and life trajectory as well as the multifaceted consequences and causes of each of those changes. One implication is that treatments should, beyond providing education, seek to assist persons with schizophrenia to integrate the broad range of complex and potentially deeply painful experiences which are associated with mental illness into their own personally meaningful, coherent and adaptive picture.

TL;DR

This review synthesizes recent research on insight in schizophrenia spectrum disorders, showing that poor insight predicts poorer treatment engagement and community function, while good insight can paradoxically predict depression, demoralization, and lower self-reported quality of life. It proposes an integrative model in which insight requires integrating internal, external, interpersonal, and life-trajectory information, and suggests treatments should help persons make personally meaningful sense of illness experiences.

Key findings

  • Poor clinical insight was associated with negative medication attitudes, medication refusal, non-adherence, poorer therapeutic alliance, higher symptom severity, and poorer community function; in a summary of literature published between 2005 and 2015, poor insight predicted poor adherence in 20 of 26 studies reviewed.
  • Good clinical insight was linked to depression, hopelessness, demoralization, lower self-reported quality of life, and heightened suicidality; a meta-analysis of 50 cross-sectional studies found a weak relationship between clinical insight and depression, but longitudinal studies suggested a stronger, more complex relationship, and several studies found the insight–depression link was mediated by self-stigma.
  • Poor insight has multiple proposed roots: anomalous experiences, brain structure/function abnormalities, neurocognition, social cognition, metacognition, and social/political factors; meta-analyses found a very weak link between neurocognition and insight and a clinically significant but modest link between theory of mind and insight.
  • Existing and emerging treatments may influence insight: CBT-p, motivational interviewing, mindfulness-based interventions, antipsychotics, metacognitive training (MCT), and metacognitive reflection and insight therapy (MERIT); in a first-episode psychosis MERIT trial, treatment completion was 80%, with significant improvements in objective clinical insight versus treatment as usual and no evidence of heightened depression, while MCT findings were equivocal.

Methods

  • Narrative review; literature was found through searches of PubMed, Scopus, PsycINFO, and EBSCO using terms including “insight”, “awareness of illness”, “self-reflection”, “treatment adherence”, “psychosis”, and “schizophrenia”; English articles published from 2014 onward were included.
  • The review considered clinical insight (awareness of symptoms, need for treatment, and psychosocial consequences) and cognitive insight (self-reflectiveness and resistance to excessive certainty); unless otherwise specified, the population studied included adults with a schizophrenia spectrum disorder.
  • Main analysis was a qualitative synthesis of recent studies and earlier models, leading to a proposed integrative model of insight; no formal meta-analysis or quantitative pooling by the authors is reported.

Limitations

  • Stated in the paper: mixed neuroimaging findings may reflect inconsistent definitions of insight, varying instruments used to measure insight, and heterogeneous sample characteristics; longitudinal and more inclusive studies are needed, and many questions remain about causal pathways and whether subtypes of poor insight should be distinguished.
  • Evident from the text: as a narrative review, it does not report systematic quality appraisal, risk-of-bias assessment, or quantitative pooling; the search was restricted to English-language articles from 2014 onward, which may omit earlier or non-English evidence.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
