Witchcraft and Biopsychosocial Causes of Mental Illness: Attitudes and Beliefs About Mental Illness Among Health Professionals in Five Countries.

This study examines the intercorrelation of measures reflecting beliefs about and attitudes toward people with mental illness in a sample of health professionals (N = 902) from five countries: Brazil, China, Ghana, Nigeria, and the United States, and, more specifically, the association of beliefs in supernatural as contrasted with biopsychosocial causes of mental illness. Factor analysis of a 43-item questionnaire identified four factors favoring a) socializing with people with mental illness; b) normalizing their roles in society; c) belief in supernatural causes of mental illness (e.g., witchcraft, curses); and d) belief in biopsychosocial causes of mental illness. Unexpectedly, a hypothesized negative association between belief in supernatural and biopsychosocial causation of mental illness was not found. Belief in the biopsychosocial causation was weakly associated with less stigmatized attitudes towards socializing and normalized roles.

Cross-National Analysis of Beliefs and Attitude Toward Mental Illness Among Medical Professionals From Five Countries.

This quantitative study sought to compare beliefs about the manifestation, causes and treatment of mental illness and attitudes toward people with mental illness among health professionals from five countries: the United States, Brazil, Ghana, Nigeria, and China. A total of 902 health professionals from the five countries were surveyed using a questionnaire addressing attitudes towards people with mental illness and beliefs about the causes of mental illness. Chi-square and analysis of covariance (ANCOVA) were used to compare age and gender of the samples. Confirmatory factor analysis was employed to confirm the structure and fit of the hypothesized model based on data from a previous study that identified four factors: socializing with people with mental illness (socializing), belief that people with mental illness should have normal roles in society (normalizing), non-belief in supernatural causes (witchcraft or curses), and belief in bio-psycho-social causes of mental illness (bio-psycho-social). Analysis of Covariance was used to compare four factor scores across countries adjusting for differences in age and gender. Scores on all four factors were highest among U.S. professionals. The Chinese sample showed lowest score on socializing and normalizing while the Nigerian and Ghanaian samples were lowest on non-belief in supernatural causes of mental illness. Responses from Brazil fell between those of the U.S. and the other countries. Although based on convenience samples of health professional robust differences in attitudes among health professionals between these five countries appear to reflect underlying socio-cultural differences affecting attitudes of professionals with the greater evidence of stigmatized attitudes in developing countries.

An assessment of attitudes towards people with mental illness among medical students and physicians in Ibadan, Nigeria.

OBJECTIVE: The authors surveyed attitudes towards mental illness among Nigerian medical personnel at three different levels of training and experience: medical students who had not completed their psychiatry rotation, medical students who had competed their psychiatry rotation, and graduate physicians. METHODS: Six questions addressed beliefs about the effectiveness of treatments for four specific mental illnesses (schizophrenia, bipolar disorder, depression, and anxiety) and two medical illnesses (diabetes and hypertension) among the three groups. A self-report questionnaire including 56 dichotomous items was used to compare beliefs about and attitudes towards people with mental illness. Factor analysis was used to identify key attitudes and analysis of covariance (ANCOVA) was used to compare the groups adjusting for age and personal experience with people with mental illness. RESULTS: There were no significant trends in attitudes towards the effectiveness of medication. Exploratory factor analysis of the beliefs and attitudes items identified four factors: (1) comfort socializing with people with mental, illness; (2) non-superstitious beliefs about the causes of mental illness; (3) neighborly feelings towards people with mental illness; and (4) belief that stress and abuse are part of the etiology of mental illness. ANCOVA comparing attitudes among the three groups showed that on three (1, 2, and 4) of the four factors medical students who had completed a rotation in psychiatry had significantly higher scores than the medical students who had not completed a rotation in psychiatry. Graduate physicians showed a similar pattern scoring higher than the medical students who had not completed a rotation in psychiatry in two factors (1 and 4) but showed no differences from students who had completed their psychiatry rotation. CONCLUSION: While beliefs about medication effectiveness do not differ between medical trainees and graduate professionals, stigmatizing attitudes towards people with mental illness seem to be most strongly affected by clinical training. Psychiatric education and especially clinical experience result in more progressive attitudes towards people with mental illness.

Proteomic analyses of serous and endometrioid epithelial ovarian cancers - cases studies - molecular insights of a possible histological etiology of serous ovarian cancer.

PURPOSE: Epithelial ovarian carcinogenesis may occur de novo on the surface of ovarian mesothelial epithelial cells or from cells originating in other organs. Foreign Müllerian cell intrusion into the ovarian environment has been hypothesized to explain the latter scenario. In this study, MALDI MS profiling technology was used to provide molecular insights regarding these potentially different mechanisms. EXPERIMENTAL DESIGN: Using MALDI MS profiling, the molecular disease signatures were established in their anatomical context. MALDI MS profiling was used on serous and endometrioid cancer biopsies to investigate cases of epithelial ovarian cancer. We then applied bioinformatic methods and identification strategies on the LC-MS/MS analyses of extracts from digested formalin-fixed, paraffin-embedded tissues. Extracts from selected regions (i.e. serous ovarian adenocarcinoma, fallopian tube serous adenocarcinoma, endometrioid ovarian cancer, benign endometrium, and benign ovarian tissues) were performed, and peptide digests were subjected to LC-MS/MS analysis. RESULTS: Comparison of the proteins identified from benign endometrium or three ovarian cancer types (i.e. serous ovarian adenocarcinoma, endometrioid ovarian adenocarcinoma, and serous fallopian tube adenocarcinoma) provided new evidence of a possible correlation between the fallopian tubes and serous ovarian adenocarcinoma. Here, we propose a workflow consisting of the comparison of multiple tissues in their anatomical context in an individual patient. CONCLUSION AND CLINICAL RELEVANCE: The present study provides new insights into the molecular similarities between these two tissues and an assessment of highly specific markers for an individualized patient diagnosis and care.
