Examining the association between evidence-based practice and the nurse-patient therapeutic relationship in mental health units: A cross-sectional study.

AIMS
To examine the relationship between the dimensions of evidence-based practice and the therapeutic relationship and to predict the quality of the therapeutic relationship from these dimensions among nurses working in mental health units.


DESIGN
A cross-sectional design.


METHODS
Data were collected between February-April 2018 via an online form completed by nurses working at 18 mental health units. Multiple linear regressions were used to examine the relationship between the dimensions of evidence-based practice and therapeutic relationship. Questionnaires were completed by 198 nurses.


RESULTS
Higher levels of evidence-based practice were a significant predictor of a higher-quality therapeutic relationship (β: 2.276; 95% CI: 1.30-3.25). The evidence-based practice factor which most influenced an improved therapeutic relationship was the nurses' attitude (β: 2.047; 95% CI: 0.88-3.21). The therapeutic relationship dimension which was most conditioned by evidence-based practice dimensions was agreement on tasks, which was most favourable with a better attitude (β: 0.625; 95% CI: 0.09-1.16) and greater knowledge and skills for evidence-based practice (β: 0.500; 95% CI: 0.08-0.93).


CONCLUSION
In mental health settings, the therapeutic nurse-patient relationship is positively enhanced by evidenced-based practice and the nurse's level of experience, with a great influence on shared decision-making.


IMPACT
This research sought to examine the relationship between the evidence-based practice and the therapeutic relationship in mental health nursing. This study demonstrates that an improved attitude and knowledge of evidence-based practices of mental health nurses increases shared decision-making with patients, which is a basic requirement for person-centred care. Because the therapeutic relationship is considered the backbone of nursing practice in mental health units, this research will have an impact on both mental health nurses and mental health unit managers.
