empathy is one of the most important aspects in the medical profession ( 110 ) and when it is employed in the right capacity it can be very effective in the relationship between doctor and patient ( 11 ) .
empathy is a very important tool in understanding the concerns and suffering of the patient from their perspective , so that the patient feels understood and has been given assistance ( 1215 ) .
some studies ( 16 , 19 ) suggest that empathy in physicians would lead to better patient care because ( a ) it increases satisfaction ( 2 , 19 ) , ( b ) it increases indulgency ( 20 ) , ( c ) it enhances the ability of physicians to diagnose and treat ( 20 ) , and ( d ) it could lead to a significant reduction in medical malpractice ( 21 ) .
the jefferson scale of empathy ( jse ) is an instrument that has been designed to assess empathy in the medical profession ( hp version ) and related students ( s - version ) ( 22 ) . in iran ,
several studies have been carried out in the field on medical students ( 2 , 22 ) , but there is no study regarding one of the most important components of the patient - physician relationship which is among ras and their potential as future professionals .
the aim of this study was to measure empathy score among ras in mashhad , iran , during a period from march to september , 2015 .
similar studies were used to determine the sample size ( 3 ) . in iran ,
the iranian student version of the jpse - s was distributed to 120 clinical ras from five large governmental hospitals in mashhad ( iran ) in september 2015 and they were give twenty minutes to independently complete the questionnaire . a total of 98 volunteers completed the jspe - s .
participation was completely voluntary and ras received no remuneration for their part in the study .
jspe - health professional version is an instrument to measure patient care among physicians ( 17 ) .
jspe is a self - report tool and includes 20 likert - type items answered on a seven point scale ( from strongly disagree to strongly agree ) .
furthermore , a factor structure of jse has been evaluated using exploratory factor analysis ( efa ) and a three - factor structure has been used , including perspective taking , compassionate care , and ability to stand in patients shoes ( 14 ) .
the data of this study were analyzed using spss version 17 ( spss inc . , chicago , illinois , usa ) descriptive statistics including tests for assessing the normality of the data and independent - samples t - test to assess the difference of empathy between the two sexes .
independent sample t - test and multivariate analysis of variance ( manova ) were used to assess the effect of gender on scores of jse and its three factors . in order to investigate the underlying components of the jspe
, data were subjected to principal component analysis ( pca ) by using varimax rotation method .

of the 120 ras who received the jspe - s , 98 completed and returned the survey .
seventy four of the 98 who completed the survey were effective , giving an overall effective response rate of 83.5% .
the average age was 31.49  4.49 and the majority were male ( 58% ) .
there were three specialties : 15 ( 20.3% ) in surgery , 30 ( 40.5% ) in internal medicine , and 29 ( 39.2% ) in psychiatry .
there were no statistically significant differences between the groups regarding gender and age ( p0.05 ) .
mean score of jse in female was 83.87(15.68 ) and in male was 89.37(14.48 ) .
the mean scores for each of the three factors of the scale were also calculated .
the mean scores for perspective taking were 38.90 ( 13.11 ) and compassionate care were 39.27 ( 7.94 ) , standing in the patients shoes was 8.89 ( 2.80 ) .
table 1 shows the rotated factor loadings for the jspe , based on the responses of the 70 ras .
subsequent tests of between - subjects effects showed that the female group scored significantly higher on perspective taking ( p=0.044 ) ( mean of perspective taking in female vs. male : 39.7/35.7 ) .
also , an inverse significant relationship was found between the ras age and mean empathy score ( pearson correlation= 0.204 , p= 0.08 ) .
statistical analysis showed that perspective taking between the two age groups was statistically significant ( p= 0.027 ; confidence interval ci = 1.3913.35 ) .
spearman s rho test also showed a significant negative correlation between age and average score of empathy ( correlation coefficient : 0.257 ; p= 0.02 ) . among the three specialties : psychiatric , internal medicine , and surgery , statistical analysis showed that there was a significant difference in total empathy score and perspective taking .
post hoc tests also showed that empathy score in psychiatric ras is more than surgery ras ( table 2 , figure 1 ) . in the fourth year of education , students had higher perspective taking scores than students in second year ( p=0.04 ) .
in compassionate care between groups , there was a significant difference ( p 0.001 ) and the average score of empathy extended further by increasing the interest in their field .
the aim of this study was to examine the levels of patient empathy in ras .
the mean empathy score of this study ( mean = 87.67 ) was lower than in the japanese ( mean = 104.3 ) , kuwaiti ( mean = 104.6 ) , iranian medical students ( mean = 105.1 and 110.41 ) , and chinese ( mean = 109.60 ) ( 2224 ) studies respectively
. this may be due to the differences in cultural factors , custom , ethnicity , spiritual belief , educational system , variation of selection of ras , and availability of appropriate role model .
average score of empathy was higher in women than in men , which is similar to other studies ( 25 ) ( 2629 ) .
also in dental students , it was shown that females scored significantly higher on the jspe than males ( 29 , 30 ) ( 31 ) .
women show a greater understanding of the emotional support , which is important to develop interpersonal relationships with patients ( 32 ) .
also , several studies have shown that female physicians ( 2 ) and female medical students ( 1 , 23 ) gain higher empathy scores in the care of patients . the results of this study are aligned with previous studies .
gender also has shown the difference of empathy in the three factors of the scale and observed that , difference exists only in perspective taking , while in the study of van ryn et al .
( 33 ) , in both domains of perspective taking and compassionate care , there were significant differences . in the study of prabhu
et al . ( 34 ) , the mean empathy score of male students is greater than that of female students . in this study , regarding empathy among different ages , there was a decrease with increase in age , which is similar with the study of khademalhosseini et al .
but in a deliang wen study , there were no significant differences in the age groups .
these studies are similar to those of chinese ( 25 ) , japanese ( 23 ) , korean ( 33 ) , portuguese ( 34 ) , and kuwaiti ( 24 ) medical students , but were different with american ( 35 , 36 ) medical students .
empathy score among ras was found to increase by the advance in their educational years .
ras should be educated in a way that they learn both scientific concepts of medicine and communication with patients and also learn how to empathize with them .
ras must learn how to treat patients , not just to treat their diseases ( 29 , 37 ) .
a cohort study conducted on internal residency students showed that the amount of empathy with patients was much higher in the first year as compared to the last year of specialty ( 38 ) , which was contradictory to our study .
this study was cross - sectional in nature so causal inference can not be mentioned and also a prospective study is needed to follow ras annually from the beginning of first year until graduation , also larger study populations covering different ras are required to validate the results of this study
this study shows significant differences in total empathy score and perspective taking in three specialties .
practical significance of these findings is that there is need for a curriculum regarding iranian student residence assistants . with an increased sample size
, a cohort study could be a possible route for future research on this topic .
 introductionempathy , an essential component of the physician  patient relationship , may be linked to positive patient outcomes . 
 this study aimed to determine the empathy score among student residence assistants ( ras).methodsin this descriptive design ( cross - sectional study ) , 102 iranian ras participated in the study during 2015 , completing the jefferson scale of empathy ( jspe ) . 
 data collection was analyzed using spss version 17 . 
 manova , independent - samples t - test , spearman correlation and confirmatory factor analysis ( cfa ) were used for data analysis.resultsmean score of jse in the sample was 87.06 ( 15.14 ) . 
 the mean scores for perspective taking , compassionate care , and standing in the patients shoes were 38.90 ( 13.11 ) , 39.27 ( 7.94 ) , and 8.89 ( 2.80 ) respectively . among the three specialties , ( psychiatric , internal medicine , surgery ) 
 results showed significant differences in total empathy score ( p=0.001 ) and perspective taking score ( p= 0.008).conclusionsthis study showed significant differences in total empathy score and perspective taking in three specialties . 
 we suggest that the curriculum in iranian ras include more teaching on empathy and communicational skills .
