“…This is because the special qualities of psychoses in particular cultures have usually been interpreted against the background of traditional psychopathological and anthropological theories concerning the psychodynamics and the influence of differing social and personal conflictual themes [32,62] . Hence, in comparisons of schizophrenia psychopathology between India and the Western world (Wales and USA) [63,64] , it was noted that the differing clinical presentations may be due to discrepancies in demographic features rather than cultural factors and that these differences support a multifactorial etiology. However, the subjects in this report were similar to the EPSILON patients by having recently received adequate physical treatment.…”

Background: The heterogeneity of schizophrenia psychopathology has led to a search for symptom clusters that could be related to broad features of the disease. The objectives of the study were to: (1) highlight the pattern of symptoms among Kuwaiti subjects with schizophrenia, using the ICD-10 symptom checklist; (2) assess the factor structure of the Brief Psychiatric Rating Scale 18 (BPRS-18) and BPRS-24, and (3) evaluate the relationship of the resulting factors with sociodemographic characteristics, age at onset of illness, family history of mental illness, objective indicators of quality of life, self-esteem, affect balance, family caregiver burden, patient’s perceptions of service satisfaction and needs for care. Method: Consecutive outpatients in stable condition were assessed with the BPRS and ICD-10 symptom checklist, as well as measures of quality of life, needs for care, service satisfaction and family caregiver burden. Results: There were 130 patients (66.1% men, mean age = 36.8 years, age at onset of illness = 24.2 years, duration of illness = 12.9 years). Of the ICD-10 symptoms, the commonest positive symptoms were hallucinations (58.5%) and delusions (72%). Catatonic symptoms were rare (2.9%). About a quarter of the subjects experienced 4 of the negative symptoms. In exploratory factor analysis, we broadly replicated the known syndromes for BPRS-24 (disorganization, positive, activation, manic, negative and depression) and BPRS-18 (negative, positive, activation and affect). In regression analyses, the variables independently associated with psychopathology were family income, negative affect, self-esteem, duration of illness, age, lack of money for enjoyment, met needs for care and caregiver tension. The negative syndrome had more significant associations with the variables investigated than the positive syndrome. Psychopathological scores were separable from indices of psychological well-being. Conclusion: In this first study of schizophrenia psychopathology from the Arab world, the clinical manifestations were similar to the data from the developed countries. The persistence of psychotic symptoms despite freely available antipsychotic treatment and the impact on caregiver burden call for attention to the perennial issue of treatment resistance and underscore the need for continued interaction with family members after the acute inpatient phase of treatment, in order to address the impact of symptoms.

“…In patients with first-episode psychosis in particular, hallucinations are known to be very common (e.g., a prevalence of 73% in a study of 143 first-episode patients by Rajapakse et al, 2011, and a prevalence of 75% in a study of 160 first-episode patients by Mbewe et al, 2006). The most common hallucinations experienced are auditory (Mbewe et al, 2006; Peralta and Cuesta, 1999; Rajapakse et al, 2011) followed by visual, somatic, and other hallucinations, with different rates of prevalence in both first-episode (Rajapakse et al, 2011), as well as chronic patient samples (Chaudhury, 2010; Thomas et al, 2007). …”

Data from 247 first-episode psychosis patients were used to explore associations between types of hallucinations and nine diverse clinical characteristics. Psychopathology was rated using the Scale for the Assessment of Positive Symptoms and Scale for the Assessment of Negative Symptoms (SANS). Childhood adversity was assessed with seven instruments; family history with an adapted version of the Family Interview for Genetic Studies; age at onset of psychosis and duration of untreated psychosis (DUP) with the Symptom Onset in Schizophrenia inventory; and insight with the Birchwood Insight Scale. Both principal component analysis-derived Auditory and Non-Auditory Hallucinations were similarly associated with delusions of influence, negative affect delusions (jealousy and sin/guilt), interpersonal childhood abuse, DUP, and insight. However, the two hallucination domains had different associations with grandiose/religious, paranoid, and somatic delusions; SANS score; childhood violence exposure; cannabis use disorders; and cocaine/other drug use disorders. Neither Auditory nor Non-Auditory Hallucinations were associated with childhood neglect, age at onset, alcohol use disorders, family history, or mode of onset of psychosis. Findings supports considering hallucinations not as a unitary psychopathological construct. They represent at least two domains and are correlated in different ways with diverse clinical variables.

Correlates of hallucinations in schizophrenia: A cross‐cultural evaluation

Abstract: Introduction-Demographic, clinical and familial factors may plausibly influence the manifestation of hallucinations. It is unclear if the pattern of the effects is similar in different environmental/cultural settings.
