Schizophrenia psychopathology in a Kuwaiti Arab sample

Area of Science:

• Psychiatry
• Clinical Psychology
• Neuroscience

Background:

• Schizophrenia exhibits significant psychopathological heterogeneity, necessitating symptom cluster identification.
• Understanding these clusters aids in characterizing broad disease features.
• Previous research has explored symptom patterns, but data from the Arab world is limited.

Purpose of the Study:

• To characterize schizophrenia symptom patterns in Kuwaiti subjects using the ICD-10 symptom checklist.
• To analyze the factor structure of the Brief Psychiatric Rating Scale (BPRS-18 and BPRS-24).
• To investigate associations between symptom factors and sociodemographic, clinical, and quality-of-life variables.

Main Methods:

• Assessment of 130 stable outpatients using the BPRS and ICD-10 symptom checklist.
• Inclusion of measures for quality of life, needs for care, service satisfaction, and family caregiver burden.
• Exploratory factor analysis for BPRS scales and regression analyses for variable associations.

Main Results:

• Common positive symptoms included hallucinations and delusions; catatonic symptoms were rare. Negative symptoms were present in approximately a quarter of subjects.
• Factor analysis broadly replicated known syndromes for BPRS-24 (disorganization, positive, activation, manic, negative, depression) and BPRS-18 (negative, positive, activation, affect).
• Negative syndrome showed stronger associations with variables like family income, negative affect, self-esteem, illness duration, and caregiver tension compared to the positive syndrome.

Conclusions:

• Schizophrenia manifestations in Kuwaiti Arabs are similar to those in Western countries.
• Persistent psychotic symptoms and caregiver burden suggest treatment resistance issues.
• Continued family interaction post-treatment is crucial for managing symptom impact and caregiver burden.
