Paper text:
since it was impossible to get samples from all districts of education department of isfahan , 70 primary school teachers , just from the district one were randomly selected .
one group underwent a two - day workshop education and the other one ( the study group ) was educated by booklets in non - attendance method .
firstly , the subjects were explained about the methodology and the goal of work in an orientation session .
then , an educational workshop was held by an assistant professor , a subspecialist of a child and adolescent psychiatry and her fellowship assistant for two days . after filling demographic data forms including age , sex , teaching experience and working experience with adhd students by both groups , a pretest on teachers knowledge , attitude and knowledge of function toward adhd
the questionnaire , used in this study , has already been used in a similar study14 . in this study ,
validity of data collection tool was confirmed by face validity whereas the reliability was obtained by a pilot study conducted on primary school teachers and calculation of cronbach 's alpha.14 face validity of data collection method was done through consulting with experts of child and adolescent psychiatry and content validity was approved after some changes .
to measure the reliability of questionnaire , 11 teachers with sufficient standards completed them and by using spss cronbach 's alpha was assigned which was 0.75 for knowledge questionnaires , 0.79 for attitude questionnaires and 0.71 for function questionnaires .
the only inclusion criterion in this study was having working experience of over 5 years .
exclusion criterion for workshop education group was missing both days of the workshop and for the nonattendance group , was not studying the booklet .
the workshop was hold in two days in a row in the consulting center of education department each day 5 for hours . at the ends of workshops
, the subjects answered the post - tests of knowledge , attitude and knowledge of function questionnaires .
the educational content , on the first day of the workshop , included recognition and definition of adhd , epidemiology , etiology , differential diagnosis , accompanied disorders , prognosis and the treatment .
on the second day , it was about unreal beliefs about the disorder , adhd impulse and hyperactivity control , strategies for attention increase in classrooms and schools , the manner of teacher - parents and teacher 
the second groups were educated by educational booklets in nonattendance method with the precise educational content similar to that of the workshop .
the booklet had been prepared through consultation with a child and adolescents subspecialist of psychiatry and had been approved by isfahan behavioral sciences research center .
the subjects in this group took part in a post test of knowledge , attitude and knowledge of function ten days after they had studied the booklet .
this questionnaire included a questionnaire of demographic data including age , sex , teaching experience , teaching experience with adhd children ; the knowledge questionnaire , a 33-item questionnaire with 3 responses of  right  ,  wrong  and  no idea  concerning dsm - iv - tr criteria , epidemiological disorder , etiology , accompanied disorders , differential diagnosis and adhd prognosis . each 
,  agreed  ,  no idea  ,  disagreed  and  totality disagreed  .
scoring scale was + 5 for the correct answer and + 1 for the wrong one .
 never  for which each correct answer of  always  scored + 2 ,  on average  + 1 and each answer of  never  was coded as zero .
in group of workshop , 33 subjects remained in the study and two were left out of the study due to attending just one day to the workshop . in nonattendance group ,
34 subjects took part in the study ; one did not take post - test due to being sick .
the data were analyzed using spss version 18 and the mean score ( sd ) of variables calculated .
then , mean scores of teachers knowledge , attitude and knowledge of function between the two groups were compared using ancova test .
among 67 teachers attending the study , the mean age was 41.677.61 years ranging between 25 - 55 years .
all subjects were accidentally married and had experience of teaching adhd students . in order to perform co - variance analysis
, the normal response variable and the variance between the two groups must be the same .
the normal distribution of the variables ( knowledge , attitude , and teacher function ) were approved and the levene 's test showed similar variances of the scores in knowledge , attitude and knowledge of function ( p > 0.05 ) . based on the above table , mean year of education , with regard to calculation of 12 years for a high school diploma , 14 years for an associate degree and 16 years for a bachelor 's degree , was 1410.5 in workshop group and 14.822.5 in nonattendance group .
mean year of experience in workshop group was 18.36.5 and in nonattendance group was 19.719.75 . as presented in table 2 , the mean scores of knowledge between the two groups of workshop and nonattendance ( after checking the controlling variable ) was not significantly different after intervention ( p = 0.8 ) which means that the increase in teachers knowledge was nearly the same in workshop and non - attendance group .
the mean ( sd ) of demographic characteristics in teachers based on two groups of workshop and nonattendance education .
based on the table 2 , the mean scores of attitude showed a significant difference between the two groups ( p < 001 ) which means that in workshop group , the change in teachers attitude after education was more positive compared to that of nonattendance group . finally ,
as presented in table 2 , mean scores of knowledge of function between the two groups showed a significant difference ( after checking the controlling variable ) ( p = 0.001 ) which means that knowledge of function in workshop group was more promoted after intervention compared to that of non - attendance group .
there was no significant association between mean scores of knowledge between the two groups of workshop and nonattendance education .
the less knowledge teachers have about adhd , the more destructive behaviors the children may have in the classrooms.15 former studies have shown workshop education to be more effective in increasing teachers knowledge.16 nowadays , e - learning through internet and computers has yielded positive results . in a study ( 2006 ) , conducted on 7 - 14 year old adolescents , on e - education of anxiety management strategies,_it was revealed that this method of education was effective to decrease anxiety.17 in another comparative study on the effect of cognitive behavioral therapy to decrease adolescents anxiety by two methods of attendance and non - attendance education , no significant difference was seen .
but , non - attendance method took less time ( 4 sessions ) compared to attendance method ( 12 sessions ) . in regards
to the attitude , there was a significant difference between the two groups ( p < 0.05 ) which means that workshop group showed more attitude change than nonattendance group . since
, workshop education is counted as an active face to face method18 and with regards to the fact that a change in attitude needs different steps , of which , one is having active education and relationship with learners,19 , this method seems to be a more effective method to change attitude19 compared to nonattendance method .
there was a significant difference between knowledge of function mean scores of the two groups ( p < 0.05 ) .
it was so that the knowledge of function had been more promoted in the workshop education compared to nonattendance group .
although enough knowledge about behavioral strategies is essential to have appropriate knowledge of function , it can not guarantee appropriate practice in real situations .
although such tests are not valid enough to measure individuals field function20 , with regard to the measurement of knowledge of function , it seems in workshop group , compared to nonattendance group , the problems are better solved due to discussing teachers problems in details and getting an answer of face to face.18
nonattendance education has been effective to increase teachers knowledge in dealing with adhd as much as workshop education , but workshop education seems better for an attitude change and increase of knowledge of function compared to nonattendance education .
this short term study was conducted on primary school teachers in district one education department in isfahan , which can be counted as a limitation .
further long term studies are suggested to be conducted with a higher number of samples and in all districts of education department in the city with post - tests taken in the 3 and 6 month post - intervention in order to check the retention of teachers knowledge and its application in the classrooms .
the quality of the workshop affects the results , and it could be considered as a limitation of study .
another limitation for this study was preparation of a primary booklet with an applicable content for primary school teachers who had lots of experience in facing with this sort of students in classrooms .
ns and mk carried out the design and coordinated the sessions of teachers , collected data and prepared the manuscript .
background : attention deficit hyperactivity disorder ( adhd ) is the most common childhood behavioral disorder causing hyperactivity , attention deficit and education decline among students . 
 the teachers may not have enough knowledge about this disorder and are in a real need in this field . 
 teachers education is one of the ways to get knowledge about this disorder . nowadays , finding a way like 
 a short term nonattendance education method is highly in demand . 
 therefore , the aim of the study was to compare effectiveness of nonattendance and workshop education of primary school teachers on their knowledge , attitude , and function towards adhd students.methods:sixty seven primary school teachers from the first districts of education department of isfahan were randomly selected and put into two groups of workshop education ( 33 participants ) and nonattendance education ( 34 participants ) . at first , both groups filled demographic date questionnaires and then , were given a pretest . 
 post tests were given after a two day education in workshop group and after ten days in nonattendance group who had studied the related booklet . finally , the mean post test scores of knowledge , attitude and knowledge of function were compared between the two groups using ancova analysis.results:after intervention , the mean scores of knowledge between the two groups was not significantly different whereas the mean scores of attitude and the mean scores of knowledge of function showed a significant difference between the two groups.conclusions:nonattendance education was as effective as workshop education in promotion of teachers knowledge , but workshop education was more effective in attitude change and promotion of teachers knowledge of function about dealing with adhd students .
