Introduction: intrauterine device (iud) is a safe, effective and reversible method of family planning. unfortunately, iud insertion causes anxiety and pain. the aim of study was to compare ridit analysis and kruskal-wallis test in pain and anxiety intensity of iud insertion in women referring to health centers of karaj (iran). materials and methods: in this randomized clinical trial study, 150 eligible women candidate intrauterine device insertion entered the study and were randomly divided into three groups: chamomile, placebo and control groups. data was collected from women who came to health centers in karaj (iran) in 2017. data collection tools included demographic information, spiel-berger questionnaire and pain visual analogue scale. the intensity of pain and anxiety were measured afterwards. finally, ridit analysis and kruskal-wallis test were used to rank the intensity of pain and anxiety in patients. the r-3.4.3 and microsoft's excel software were used for statistical analysis. results: the results showed that the mean±sd of age in three groups was 29.7±7.01, 28.68±8.15 and 31.6±7.71, respectively. ridit analysis and kruskalwallis test showed considerable decrease of the anxiety and pain intensity, induced by iud insertion in chamomile, placebo and control groups respectively. ridit analysis and kruskal-wallis test statistics are significant. the value of the ridit statistic was x^2=20.23,p<0.001 and the value of kruskal-wallis test is x^2=18.67, p<0.005 in pain intensity. moreover, the value of the ridit statistic is x^2=3.92, p<0.001 and the value of kruskal-wallis test is x^2=21.37, p<0.005 in anxiety intensity. conclusions: the results of this study suggested that, there is less significant difference in ridit analysis than kruskal-wallis test among the three groups in decreasing pain and anxiety intensity.
