Delusional Distress is Associated With Emotion Dysregulation in Schizophrenia-Spectrum Disorders

Area of Science:

• Psychiatry and Psychology
• Clinical Neuroscience

Background:

• Delusional beliefs' persistence is often linked to their distressing nature.
• Global emotion dysregulation is a potential mechanism underlying this distress.
• While associated with general psychotic symptoms, its specific link to delusional distress requires examination.

Purpose of the Study:

• To investigate the relationship between global emotion dysregulation and delusional distress in individuals with schizophrenia-spectrum disorders.
• To identify specific aspects of emotion dysregulation associated with delusional distress.

Main Methods:

• 100 individuals with schizophrenia and 52 controls completed measures of delusional ideation (Peters Delusion Inventory; PDI-21) and emotion dysregulation (Difficulties in Emotion Regulation Scale; DERS-16).
• Participants with schizophrenia also completed a delusion severity measure (Psychotic Symptom Rating Scales; PSYRATS).
• Linear regression analyses assessed relationships between delusion severity and emotion dysregulation, controlling for covariates. Stepwise regression identified specific associations with delusional distress.

Main Results:

• Individuals with schizophrenia exhibited significantly higher global emotion dysregulation across all subscales compared to controls.
• Emotion dysregulation was significantly associated with delusional distress on both PDI-21 and PSYRATS.
• Limited access to emotion regulation strategies was specifically linked to higher delusional distress on both measures, even when controlling for delusional preoccupation.

Conclusions:

• Emotion dysregulation, particularly a lack of accessible regulation strategies, is significantly related to delusional distress in schizophrenia.
• Interventions aimed at enhancing emotion regulation strategies may offer a pathway to reduce distress associated with delusional thinking.
