The quality of nursing research have been improving in a great magnitu- de currently.However, we should continue our effort on other aspects in order to gain respects from non-nursing researchers. The aim of this study was to evalua- te the appropriateness of study design, sampling methods, validity and reliabil- ity of instruments, and inferentila statistics used in quantitative nursing res- earch. One-year publications in three domestic nursing journals (including Nursing Research, Chang Gung Nursing,VGH Nursing) (n=67) were evaluated.Descriptive or analytical study was most common (70.1%),followed by quasi-experiments (26.9%), and assessment of validity and reliablility of a instrument (11.9%).About half of the studies used purposive or convenient method to obtain the study sample, limiting its ability in generalization of the results. A total of 118 instruments used in htese papers, 61 were developed by the researchers, 25 were translated from foreign questionnaires, and 32 used existing Chinese questionnaires. Expert validity and Cronbach's �` was primarily used for evaluation of validity and reliability, respectively, suggessting other assessments in validity and reliability should be encouraged as well.About half of the instruments from developed by the researchers or translated foreign questionnaires did not show the whole content, creating some difficulty for other researchers to reproduce similar studies. Problems such as multiple comparisons not used or not mentioned in a significant one-way ANOVA, not specified which methods for correlation coefficients or for multiple linear regression, not examined the statistical assumptions in multiple linear regression, confusion between significant level and p-values, indicated some of nursing researchers are not familiar with statistical methods.
