RESUMEN
BACKGROUND: Research shows that personnel working in mental health facilities may share some of the societal prejudices towards mental illness. This might result in stigmatizing behaviours towards people suffering from mental disorders, undermining the quality of their care. AIMS: To describe and compare attitudes towards mental illness across a sample of professionals working in a wide range of mental health facilities in Spain, Portugal and Italy. METHOD: We administered a survey to personnel including two questionnaires related to stigmatizing attitudes: The Community Attitudes toward the Mentally Ill (CAMI) and the Attribution Questionnaire (AQ-27). Data were compared according to professional category, work setting and country. RESULTS: 34.06% (1525) professionals of the surveyed population responded adequately. Psychologists and social therapists had the most positive attitudes, and nursing assistants the most negative, on most factors of CAMI and AQ-27. Community staff had more positive attitudes than hospital-based professionals in most factors on CAMI and in discriminatory responses on AQ-27. CONCLUSIONS: Globally, mental health professionals showed a positive attitude towards mental illness, but also a relative support to coercive treatments. There are differences in attitudes modulated by professional category and setting. Results can guide preventive strategies, particularly for the hospital-based and nursing staff.
