Cognitive regulation of negative affect in schizophrenia and bipolar disorder

Abstract

Schizophrenia (SZ) and bipolar disorder (BD) exhibit common cognitive deficits that may impede the capacity for self-regulating affect. We examined the use of particular cognitive strategies for regulating negative affect in SZ and BD, and their associations with levels of mood symptomatology. Participants were 126 SZ, 97 BD, and 81 healthy controls (HC) who completed the Cognitive Emotion Regulation Questionnaire (CERQ), the Depression Anxiety Stress Scales (DASS) and the Hypomanic Personality Scale (HPS). Patients with SZ and BD reported more frequent rumination, catastrophising and self-blame, and less use of putting into perspective, relative to HC. Additionally, SZ patients were more likely to engage in other-blame, compared to HC. The most consistent predictors of symptomatology for SZ were self-blame and catastrophising, while for BD were rumination and reduced positive reappraisal. These findings demonstrate maladaptive use of cognitive strategies to self-regulate negative affect in SZ and BD, resembling those reported previously for unipolar depression. The ineffective use of adaptive cognitive reframing strategies in both patient groups may reflect the impact of their shared cognitive deficits, and requires further investigation. Remediation of cognitive capacities contributing to ineffective self-regulation may facilitate reduced mood symptomatology in SZ and BD.
