Background: This paper describes the views of clinical nurses regarding the utilization of nursing research in practice. Many studies reviewed in the literature have taken a quantitative approach and have focused on why nurses constrain to develop research for nursing and research participation. There is a need to understand what restricts clinical nurses to use research findings. The aim of this study was to discover practising nurses' view of aspects which they perceived restricted them from research utilization.

Method: Data were collected during 6 months by means of face-to face interviews follow by one focus group. Analysis was undertaken using a qualitative content analysis aided by MAXQDA soft ware.

Results: In this study findings disclosed some key themes perceived by nurses to restrict them to use research findings: 'level of support require to be research active', 'To be research minded ', 'The extent of nurses knowledge and skills about research and research utilization', ' level of educational preparation relating to using research', 'Theory –practice gap', and Administration and executive challenges in clinical setting.

Discussion & Conclusion: This study identifies constraints that require to be overcome for clinical nurses to actively get involved in research utilization. In this study nurses were generally interested to use research findings. However they felt restricted because of lack of time, lack of peer and manager support and limited knowledge and skills of the research process. This study adds a qualitative perspective, although findings are not generalizable, they support quantitative study findings in to this subject. This study also confirms that research utilization and the change to research nursing practice are complex issues which require both organizational and educational efforts.
