The purposes of this predictive correlational research were to study the research utilization in nursing practice and to examine the predictability of predicting factors; research experience, educational level, research climate, support resources, and staffing. 447 nurses were selected by multi-stage sampling, who working in regional hospitals under the Jurisdiction of Ministry of Public Health in Thailand. The instruments were personal dada form, research utilization in nursing practice scale, research climate scale, support resources scale and staffing scale. All scales were tested content validated by 5 experts and construct validity. The Cronbach’s alpha coefficient of all scales were .95, .88, 94, and .93 respectively. Stepwise multiple linear regression was used in statistical analysis. The major findings were as follow. 1. The research utilization in nursing practice among professional nurses was a moderate level. 2. Research experience, research climate, support resources, staffing were positively related to research utilization in nursing practice (r= .316, .440, .430, and .370 respectively, p<.05). Bachelor degree was negative related to research utilization in nursing practice (r= -.158, p<.05). 3. The research climate, research experience, and support resources accounted for 30.40%of total variance in research utilization in nursing practice (R2= .304, p<.01).
