Abstract
This paper provides a summary of the main quantitative research designs. Quantitative research designs occur in a hierarchy of evidence, ranging from descriptive research designs such as cross-sectional studies, and cohort designs, to more carefully constructed experimental designs like randomised control trials (RCT's). The quality of a study's findings is determined by factors affecting its internal validity and its application to other settings is gauged by its external validity.
期刊介绍：
The Journal of Psychiatric and Mental Health Nursing is an international journal which publishes research and scholarly papers that advance the development of policy, practice, research and education in all aspects of mental health nursing. We publish rigorously conducted research, literature reviews, essays and debates, and consumer practitioner narratives; all of which add new knowledge and advance practice globally.
All papers must have clear implications for mental health nursing either solely or part of multidisciplinary practice. Papers are welcomed which draw on single or multiple research and academic disciplines. We give space to practitioner and consumer perspectives and ensure research published in the journal can be understood by a wide audience. We encourage critical debate and exchange of ideas and therefore welcome letters to the editor and essays and debates in mental health.
