time employment , 2 ) a bachelor s degree in nursing or higher , 3 ) currently working in a pediatric ward or at least one year of experience work doing so , and 4 ) between the ages of 2555 . the exclusion criteria were : 1 ) foreign nurses and 2 ) working part - time or on contract . based on the inclusion and exclusion criteria , 100 participants were chosen from the three intervention hospitals and 100 participants were chosen from the one control hospital . in the intervention group , one participant dropped out for the follow - up intervention assessment ( after three months ) and three participants dropped out for the follow - up in the control group ( after three months ) . a post - test was conducted immediately , and follow - up was conducted in both groups after three months . there were 200 participants during the study period at baseline ( 100 in intervention and 100 in control ) , and there were 196 participants at three months ( 99 in the intervention group and 97 in the control group ) who completed the three - month , post - intervention assessment . the participants in the two groups answered the questions in the same questionnaire that was used at the beginning and after three months . to determine the most commonly - held nurses attitudes , we conducted an elicitation study on a sample of 15 nurses who worked in the pediatric wards . in this stage , each interview lasted for 3575 minutes . in every part of the interview , we used the probing method to get additional information and to get clarification of the information ( table 1 ) . all interviews were conducted by researchers , and the interviews were continued until the researchers felt that the maximum amount of information had been obtained . four more interviews were conducted to ensure that a total of 15 interviews was conducted . in this research the interviews were transcribed verbatim , and they were analyzed simultaneously with the data collection process . after each interview , the information was recorded in the shortest possible time , and the information was reviewed two or three times . the nurses sentences , each typically in the form of an expression of the meaning of a word and their implications were extracted from the interviews . to facilitate the detection of the thoughts they had expressed during the interviews , relevant clauses were inserted . then , the information gathered from the interviews was classified into relevant categories , and we used the findings of the qualitative research ( semi - structured interviews with nurses and children ) . thirty - one items were collected and evaluated on a 5-point likert scale ( strongly agree , agree , neutral , disagree , strongly disagree ) . then , we conducted a pilot study to assess the reliability of the questionnaire and gathered additional comments from the population about the items on the questionnaire to prepare the final draft of the questionnaire for the main study . since the socio - demographic characteristics of subjects can affect the correlations among the variables in the proposed model , we included in the pilot questionnaire the participants ages , levels of education , work experience in the hospital , and work experience in pediatric wards . in the pilot study , the questionnaire was tested with 30 pediatric nurses in hospitals affiliated with shahid beheshti university to provide a brief introduction to the study and so the researcher could explain the importance of their participation in the study . then , the participants were asked to follow the hyperlink at the end of the invitation . in keeping with the requirements of research ethics , the first page of the research project provided an introduction to the study and its objectives and indicated the requirements for participation in the study . to assess the participants attitudes concerning the study , we incorporated related statements , such as  the mother s participation helps a hospitalized child feel secure  and  the mother s participation shortens the duration of hospitalization .  fcc based on the theory of planned behavior survey that was used in this study consisted of two sections . section one included questions about demographic variables , and section two consisted of a tool to measure pediatric nurses attitudes toward fcc . some questions had negative scores ( att15-att20 and att24-att26 ) , we conducted data analysis after recoding . validity is defined as whether a scale yields meaningful information about the behavior / construct in which the researcher is interested . the measures in this study were evaluated by the researcher , her faculty adviser , and a pilot group of experts . in addition , the validity of the content of each of the scales was assessed by manuals that provided specific instructions for creating each subscale , to clearly represent the necessary components of the constructs in the tpb model ( 1416 ) . the specific wording of each item was consistent with an accurate reflection of the construct of perceived behavioral control in the tpb ( 16 ) . this same level of instruction was used for each domain . given that the guidelines from theory developer ( ajzen ) in 2005 were followed explicitly to create these measures , they were esteemed to adequately reflect the constructs from his theory of planned behavior . the tool was validated by the content validity index ( cvi ) and face validity methods . to validate the content , we sent the questionnaire to two faculty members at university putra malaysia ( upm ) who were experts in pediatric nursing and to five faculty members at shahid beheshti university and tarbiat moddaress university in tehran who were experts in pediatric nursing for corrections , suggestions and feedbacks . expert panels , the members of which were selected based on their experience , certified that the content of the instrument was valid . they were asked to review the items on the questionnaire for clarity and to determine whether they fit the subscale label and definition . the professionals were nursing faculty members , supervisors , and members of the nurses staffs . measurements of attitude , subjective norms , perceived behavior control , intention , and behavior of family - centered care were obtained through questionnaires based on theory of planned behavior by francis in 2004 ( 16 ) . the reliability ( internal consistency ) of each of the scales was tested using cronbach s alpha reliability coefficients . the results of the reliability tests indicated that , for the control group , the values of chronbach s alpha for all related items were almost 0.8 or above , which showed that the instrument had adequate consistency and reliability across the study . descriptive statistics were used to describe the demographics of the sample and background variables . to evaluate the main research hypotheses of the current research , we used the inferential method , including two - way repeated measure analysis of variance ( rmanova ) , followed by the bonferroni test for mean comparison between the control group and the experimental group at three steps , i.e. , pre - test , post - test , and follow - up test . this study was approved by the university of putra malaysia , the ministry of health sciences , and the ethics committee of the faculty of medicine and health sciences of shaheed beheshti university in iran . written informed -

way repeated measure analysis of variance ( rmanova ) , followed by the bonferroni test for mean comparison between the control group and the experimental group at three steps , i.e. , pre - test , post - test , and follow - up test . this study was approved by the university of putra malaysia , the ministry of health sciences , and the ethics committee of the faculty of medicine and health sciences of shaheed beheshti university in iran . written informed - consent forms were obtained from the nurses before were allowed to participate in the study . the sample consisted of 200 nurses who responded to the attitude questionnaire before participating in the educational intervention concerning fcc . the results of the chi - squared test indicated that there was no significant difference between the ages of the nurses in the intervention and control groups ( x = 0.166 , p = 0.920 ) . these results also indicated that 2% of the respondents in the intervention group and 2.1% of the respondents in the control group had incomes between 300 to 500 k tomans ( table 2 ) . all related items of attitude in the control group in the pre - test  mother participation secures hospitalized child feeling .  had the highest mean ( m= 4.14 , s.d= 0.59 ) followed by mother knowledge can be increase the quality of care .  ( m= 4.12 , s.d= 0.56 ) . the lowest mean related to  mother can be present when cardiopulmonary resuscitation ( cpr ) is being done on the child if they wish . also the highest mean observed for same items ( m= 4.06 , s.d= 0.58 ) and item 27 ( m= 4.07 , s.d= 0.54 ) respectively . all related items of attitude in intervention group in pre - test  the mother s participation helps a hospitalized child feel secure  had the highest mean ( m = 3.99 , s.d . = 0.51 ) , and it was followed by  the mother s participation comforts the child and takes care of her or his physical needs  ( m = 3.96 , s.d . the lowest mean value was related to  mother can be present , if she wishes , when cpr is being done on her child the highest means were observed for  the mother s presence is adequate , and her participation in providing care for her child is not required = 0.52 ) and   the mother s participation helps a hospitalized child feel secure  ( the lowest mean was observed for  the mother s participation shortens the length of the hospital stay  ( m = 2.76 , s.d . = 1.08 ) , and the same results were observed in the follow - up test . to determine how the respondents socio - demographic characteristics and attitudes concerning the provision of family - centered care were correlated , spearman correlation coefficient analyses were used to identify the demographic characteristics that had a significant relationship with attitude in the pre - test , post - test , and follow - up test . table 3 shows that no significant relationship existed between age and attitude and the provision of family - centered care ( p > 0.05 ) . in order to evaluate the differences in the mean of attitude scores within the three stages of pre - test , post - test , and follow - up test for both groups ( i.e. , the intervention and control groups ) , a two - way , repeated anova measure was used to assess whether the two groups had differences in their attitudes in the tests . the sphericity assumption states that the difference scores of the paired levels of the repeated measures factor have identical population variance . in the same way as the other anova assumptions of normality and homogeneity of variance , it is critical to mention that the sphericity assumption refers to population parameters rather than sample statistics . mauchly s sphericity test was used to evaluate the sphericity assumption , and the result showed that the sphericity assumption for attitude was violated ( x = 103.1 , p < 0.01 ) , therefore , the f - value was adjusted by a greenhouse - geisser correction . the results of repeated anova measure of attitude score showed that the interactions between the group and the tests were statistically significant ( f(1.42 , 275 ) = 168.474 , p < 0.05 ,  = 0.465 ) , therefore , to test the related hypothesis , a post - hoc test ( bonferroni test ) was used to compare the mean scores ( table 4 ) . to show the efficacy of intervention , we compared the pre - test , post - test , and follow - up test in both the intervention and control groups separately . the result of post - hoc test ( bonferroni test ) indicated that the difference between the pre - test and post - test in attitude score in intervention group was significant ( p < 0.05 ) . these results indicated that there were no significant differences between any of the tests for the control group ( p > 0.05 ) ( table 5 ) . it was evident that , in the intervention group , the mean attitude score increased after intervention , but it was consistent over time in the control group . attitude toward performance behavior reflects an individual s global positive or negative evaluations of performing a practical behavior ; that is , attitude is determined by the individual s perception about the value of a given outcome of a behavior ( 7 , 9 ) . in this study , it was found that the intervention group recorded a significant positive change in the mean attitude score ( p < 0.005 ) , and the increase in the proportion of pediatric nurses who had moderate attitude scores had increased to higher levels at the three - month follow - up . compared to the baseline , a significant increase in attitude level was observed immediately in the intervention group , and also at three months after intervention , but no such increase was observed in the control group . this difference could be attributed to the availability of information obtained from the educational process that was conducted for the intervention group . a number of factors could have contributed to the success of the intervention , such as our sample s being comprised of well - educated , motivated nurses . also , the attitudes of the nurses in the two groups ( intervention and control ) concerning the provision of fcc at three different times ( i.e. , pre - test , post - test , and follow - up test ) indicated that there was a significant association between the nurses attitudes , because the interaction between groups and the tests were statistically significant . also , the mean attitude score between the control and intervention groups in the pre - test was not statistically significant ( p > 0.05 ) , while the differences between the intervention and control groups were significant for attitude in the post - test ( p < 0.05 ) and in the follow - up test ( p < 0.05 ) , while the difference between the pre - test and post - test in attitude score in the case group was significant . it was apparent that intervention to encourage nurses to stop doing some things and start doing other things was an important step toward creating behavioral changes . the results of this study support the effectiveness of multi - component education in promoting attitude changes in pediatric nurses in iran . therefore , the results of the study indicated that hypothesis education is one of the most effective factors to improve attitude , because 93.9% of the population has no education about fcc . the mean for attitude increased in the case group , but there were no significant differences in any of the tests for the control group . this finding indicated that it is possible to achieve a significant positive change in pediatric nurses attitudes with educational intervention . similarly , the findings of a previous study indicated that it is possible to increase nurses knowledge and attitudes with the help of brief , interactive workshops . the findings of that study were based only on positive changes in rns attitudes and knowledge after four weeks of workshops ( 18 ) . in addition , intervention was effective in that it increased new mothers intentions to breast feed their babies expanded their knowledge about caring for their babies , and produced better attitudes and subjective norms ( 19 ) . so , the findings of our study were in good agreement with them concerning the importance and benefits of providing educational opportunities . based on the results of a study in shiraz , enhancing the treatment team s knowledge and attitudes concerning the positive effects of fcc treatment produced improvements in patients healthcare , qualitative improvements in healthcare services , the nurses job satisfaction ( 20 ) . in addition , it was found that this approach had a sustainable impact that lasted for an undetermined time after the intervention . it certainly was apparent at the time of the three - month follow - up test . if educational programs are based on assessments nurses needs and are conducted purposefully using different methods , such as lectures , pamphlets , posters , and booklets , nurses attitudes subjective norms , perceived behaviors , behavioral intentions , and actual behaviors can be affected in a notably positive manner ( 21 ) . also , the results of a study indicated that the mean level of nurses attitudes toward obtaining special skills were significantly different after the educational intervention ( 22 ) . comprehensive educational programs that emphasize personal educational needs reduce the cost of providing care , and improve the quality of care ( 23 ) . therefore , continuing education is a basic need to ensure that pediatric nurses can adapt to the progression of knowledge and the rapid changes in scientific approaches and people s behaviors . as evidence of this , a notable increase occurred in the mean scores of nurses knowledge immediately and at three months after the educational process ( 25 ) . in that study , the mean scores of nurses knowledge increased from 59.214.8 before their education training to 88.68.4 directly after the training and 719.8 three months after the training ( p < 0.016 ) . the results of our study were contrary to the findings of their study in that there were no significant differences in the nurses attitudes for the three times they were evaluated . the key purpose of the tpb is to provide an explanation for the att- behavior relationship ( 26 ) . tpb will be rejected if att does not predict intention , and studies that have measured att , intention , and behavior consistently have demonstrated that the more favorable an individual s attitude is toward a particular behavior , the stronger that person s intention to express that behavior will be ( 7 , 2729 ) . in 115 studies that used tpb in different areas in which the att - intention relationship was measured , att explained approximately 24% of the variance in intention ( 27 ) . . one of the most important and common problems among nurses and parents is their lack of communication and the lack of a good relationship . parental participation , which was introduced as a moral issue , may be driven now by tpb factors . this study provided evidence to support the efficacy of tpb in the design and evaluation of educational intervention to promote positive attitudes concerning the implementation of fcc . the findings supported various types of intervention , including educational material and pamphlets , posters , powerpoint presentations , lectures , and training , all of which are effective strategies in promoting fcc behaviors among nurses . the findings also indicated that , while nurses endorse the concept of fcc , its practical implementation is more problematic . also , the results of this study are being used as the basis for assisting pediatric nurses to apply the concepts of family - centered care more consistently in their practice . thus , an important target of study for future research is to follow the relationship between nurses extent of training and the importance they give fcc in practice . such research has the potential to identify the factors that lead nurses to maintain some distance between themselves and the family members of sick children .
