Painful insight vs. usable insight in schizophrenia. Do they have different influences on suicidal behavior?

Abstract

BackgroundSuicidal behavior is highly prevalent in schizophrenia. Among the risk factors, insight has been little studied and has yielded contradictory results. In addition, it has been studied neglecting relevant psychological aspects, such as beliefs about illness and coping styles. MethodWe assessed 133 outpatients diagnosed with schizophrenia according to ICD-10 criteria. Evaluation included sociodemographic, general clinical, psychopathological, psychological and suicidal behavior variables. ResultsNeither insight nor insight coupled with negative beliefs and/or coping styles were associated with suicidal behavior. Nevertheless, insight coupled with negative beliefs and/or coping styles was associated with greater hopelessness and depression, internalized stigma, worse control over illness and greater global severity as compared to insight coupled with positive beliefs and coping styles. Suicide attempt and suicidal ideation groups showed greater depression and hopelessness, worse global beliefs and worse control over illness, higher socio-economic level, and greater number of previous psychiatric admissions compared to the non-suicidal group. ConclusionsInsight coupled with negative beliefs and/or coping style was not associated with suicidal behavior. Nevertheless, it was associated with greater depression and hopelessness, both of which are firmly established risk factors for suicide in schizophrenia. Prospective studies with long-term follow-up and large samples are needed to clarify this issue. Clinicians should assess these psychological features associated with insight, both in patients with insight and in those with poor insight when promoting it.
