Available evidence clearly demonstrates that undergraduate nursing students typically hold unfavourable attitudes towards psychiatric / mental health nursing as a career. It has been suggested that students' negative attitudes towards mental illness and consumers of mental health services may be responsible for the unpopularity of this specialty area; however, research exploring the relationship between career choices and students' attitudes is lacking. A sub-set of data from a large Victorian study that examined undergraduate nursing students' attitudes towards mental illness, mental health nursing, and mental health clinical placement experiences was used to clarify the nature of this relationship. In total, complete data was available from 605 students undertaking their first mental health placement who provided responses to a 24-item pre-placement survey. This survey assessed the following three areas: 1. preparedness for the mental health field; 2. attitudes towards mental illness; and 3. attitudes towards mental health nursing. The findings demonstrate significant relationships between students' attitudes, beliefs, and characteristics and desire to pursue a career in psychiatric mental health nursing. The identification of these relationships provides a basis from which interventions to influence nursing students' attitudes towards psychiatric/mental health nursing, can be planned.
