Development and responsiveness of a scale to measure clinicians' attitudes to people with mental illness (medical student version)

Objective: We report the rationale, reliability, validity and responsiveness studies of the Mental Illness: Clinicians' Attitudes (MICA) Scale, a 16-item scale designed to measure attitudes of health care professionals towards people with mental illness. Method: Items were generated through focus groups with service users, carers, medical students and trainee psychiatrists. Psychometric testing was completed in a number of student samples. The responsiveness of the scale was tested after a 1.5 h mental illness stigma related intervention with medical students. Results: The MICA scale showed good internal consistency, alpha = 0.79. The test-retest reliability (concordance) was 0.80 (95% CI: 0.68-0.91). The standardised response mean for the scale was 0.4 (95% CI 0.02-0.8) after a mental illness related stigma intervention. Conclusion: The MICA scale is a responsive, reliable and valid tool, which can be used in medical education and mental health promotion settings and studies.
