Undergraduate nursing and midwifery student's attitudes to mental illness.

Mental health nursing students scored significantly better on all stigma subscales. Stigma worsened with a little professional exposure to people with mental illness but then improved with increasing exposure. Both personal exposure and professional exposure to people with mental illness change perceptions. The professional results follow a J-curve. Current plans for cross-field experience involving short or virtual placements during student nurse training are likely to worsen stigma rather than improve it.
