[Etiology of schizophrenia from the viewpoint of the patient]

Cross-Cultural Comparison of Explanatory Models of Illness in Schizophrenic Patients in Jordan and Germany

This study investigated illness concepts of schizophrenic patients in an Arab-Islamic and a western European cultural background. 24 Jordanian and 23 German inpatients were interviewed using an illness concept scale and a causal belief questionnaire. Jordanian patients tend to believe more in esoteric factors underlying their illness, and they perceive the illness to be more threatening. There were no differences regarding biological explanations of illness and trust in medication; however, Jordanian patients reported more trust in the treating physician. Nearly all patients mentioned psychosocial stress as an important factor underlying their illness. Concerning treatment, only Jordanian patients believed religion to be an important factor and mentioned distance from the family as beneficial. The study highlights that culturally specific factors influence illness concepts of schizophrenic patients from an Arab-Islamic and a western European cultural background. Knowledge of these illness concepts is important to establish a helpful relationship between physician and patient.

Symptoms and Etiological Attribution: A Cross-Sectional Study in Mexican Outpatients with Psychosis and Their Relatives

This cross-sectional study aimed at identifying the most common attributions of their mental disorder in a Mexican patients who have experienced psychosis and their relatives and exploring how having experienced or not characteristic psychotic symptoms and their present clinical status might affect their etiological attributions. Past and current symptom profiles of 66 patients were as assessed with the SCID-I (Structured Clinical Interview for DSM-IV Axis I Disorders) and the PANSS (Positive and Negative Syndrome Scale), respectively. The etiological attribution of psychosis of patients (n = 62) and the relatives (n = 65) was assessed with the Angermeyer and Klusmann scale comprising 30 items into five categories: biology, personality, family, society, and esoteric. Patients and relatives attribute psychosis mainly to social factors. Relatives' attributions were not influenced by clinical profile of patients, whereas in the case of patients it was only current clinical status that showed a difference, with those in nonremission scoring higher personality and family factors. Acknowledging patients' and relatives' beliefs about mental disorders at onset and later on is particularly important in psychosis, a mental condition with severe and/or persistent symptoms, in order to promote better involvement in treatment and in consequence efficacy and recovery.

Causal attribution and illness perception: a cross-sectional study in Mexican patients with psychosis

Health psychology researchers have begun to focus greater attention on people's beliefs about health/illness since these beliefs can clearly affect behavior. This cross-sectional study aimed at (1) identifying the most common factors psychotic patients attribute their illness to and (2) assessing the association between causal attribution and illness perception (cognitive, emotional, and comprehensibility dimensions). Sixty-two patients (56.5% females) who had been treated for psychosis at a public psychiatric hospital in Mexico answered the Angermeyer and Klusmann Illness Attribution Scale and the Brief Illness Perception Questionnaire. Results showed that most patients attributed psychosis onset to social factors and that attribution to their personality might have an overwhelmingly negative effect on their lives. Acknowledging psychotic patient attributional beliefs and considering them in clinical practice could improve treatment efficacy and overall recovery success. This is particularly important in psychosis, since symptoms are often severe and/or persistent and require long-term treatment.

What people with schizophrenia think about the causes of their disorder

Aims – To describe what users with schizophrenia think about the causes of their disorder. Methods – In each of the 10 participating Italian mental health centres, 25 users with schizophrenia were consecutively recruited and asked to complete the Users' Opinions Questionnaire (UOQ). Results – 150 out of 198 respondents mentioned at least one social cause for their mental disorder, and 114 reported exclusively social causes. Family conflicts were the most frequently reported social cause (21%), followed by traumas (20%), work and study difficulties (17%), and psychological disturbances (17%). Ten percent of the respondents mentioned biological causes. Biological causes were more frequently reported by users who were aware of their diagnosis of schizophrenia, whereas social causes by those who just knew they suffered from a psychosis. Difficulties in social relationships were more frequently pointed out by respondents with an earlier onset of the illness and a higher number of compulsory admissions in the previous 12 months. These users expressed more scepticism about the usefulness of the treatments they received, and perceived a greater social distance. Conclusions – Users' beliefs about the causes of their disorder should be taken into account by psychiatrists in order to improve their working alliance with them.

Causes of schizophrenia reported by urban African American lay community members

Although mental health professionals' "etiologic beliefs" concerning schizophrenia have evolved in accordance with diathesis-stress and neurodevelopmental models, little is known about etiologic attributions in nonclinical general population samples in the United States. Yet, course and outcome for people with the illness may be indirectly influenced by beliefs about causes in the larger community. Because of very limited research in this area, especially among African Americans in particular, this descriptive study investigated the causes of schizophrenia reported by 127 urban African Americans from the general population. The aim of this study was to assess the most commonly reported causes of schizophrenia, as well as the frequency of endorsing items from a list of 30 factors, some of which are congruent with current psychiatric conceptualizations of schizophrenia, whereas others are not. Results of this report complement previously reported findings from the same setting involving family members of patients with schizophrenia [Esterberg ML, Compton MT. Causes of schizophrenia reported by family members of urban African American hospitalized patients with schizophrenia. Compr Psychiatry 2006;47:221-226]. The 5 most commonly reported causes were disturbance of brain biochemistry (49.6%), drug/alcohol abuse (42.5%), hereditary factors (40.9%), brain injury (40.2%), and avoidance of problems in life (37.8%). The mean number of likely or very likely causes endorsed by participants was 7.5 +/- 5.7. Some 47.9% reported one or more esoteric factors as a cause. Of the 6 esoteric factors, possession by evil spirits (28.3%), radiation (20.2%), and punishment by God (19.7%) were most common. Esoteric causes were more commonly chosen by male participants, those with 12 years of education or less, and participants who reported never having known someone with schizophrenia. Future research should seek to better understand how esoteric beliefs about causation affect attitudes toward people with mental illnesses and acceptance of mental health treatment by those individuals. Beliefs about debunked personality, societal, family, and esoteric causes in this nonclinical sample indicate the need for improved psychoeducation of the community at large.
