Nursing educators need rigorously developed instruments to assess competency in evidence based practice (EBP) at undergraduate level. This concept is defined as the capability to choose and use an integrated combination of knowledge, skills and attitudes with the intention to develop a task in a certain context. Also, we understand that EBP is gaining knowledge and skills, as well as increasing positive attitudes toward EBP that will promote a change in behaviour to implement EBP in practice. This study aims to develop a psychometric test of the Evidence Based Practice Evaluation Competence Questionnaire (EBP-COQ) among undergraduate nursing students.
The questionnaire was developed by item generation through a review of scientific literature and focus groups. The instrument was validated in terms of content validity through an expert review. The EBP-COQ was administered to a cohort of nursing students (n =100) to evaluate test reliability and select the best items. Psychometric properties of the final instrument were assessed in a sample of 261 nursing students.
The EBP-COQ consisted of 25 items. A factorial analysis grouped the items into the three categories that define competence relating to EBP: attitude, knowledge and skills. Cronbach’s alpha was 0.888 for the entire questionnaire. The factor solution explained 55.55% of the variance.
EBP-COQ appears to measure with adequate reliability the attributes of undergraduate nursing students’ competence in EBP. The instrument is quick to disseminate and easy to score, making it a suitable instrument for nursing educators to evaluate students’ self-perceived competence in EBP.
KeywordsCompetence Evidence-based practice Undergraduate nursing Questionnaire Validation
As a result of the Bologna Process the educational systems in all European countries are in the process of reforming and harmonization. Accordingly, at the European Higher Education Space the learning model has been built on competence-based education (CBE). The characteristics of CBE are: it is oriented to the professional practice; it is learner-centred and the learning process is central; it has a constructivist approach .
In Spain, from this new framework, the National Government has determined a revision of the curricula, the teaching model and a definition of the competences in most of the degrees, included health care sciences (nursing, medicine, etc.). In the new Nursing Degree (four-year programme) one of the academic competences is related to the utilization of “Evidence-based Practice (EBP)” in the clinical decision-making .
So, the nursing curriculum should provide the acquisition and development of knowledge, attitudes and skills in EBP. For successful implementation in practice, EBP knowledge would need to result in skills, attitudes and appropriate changes in behaviour . Most evidence-based practice (EBP) educational assessment tools evaluated until today have focused on specific knowledge components or technical skills. Other important potential barriers to the adoption of EBP, such as attitudinal, perceptual and behavioural factors, have yet to be studied , especially in the undergraduate setting . Shaneyfelt  added that further development and testing is required to evaluate EBP attitudes. Tilson et al. remark the significance of this concept “EBP is gaining knowledge and skills, as well as much as increasing positives attitudes toward EBP that will promote a change in behaviour to implement EBP in practice” . Therefore, the teachers and health care educators need good quality instruments to assess the student acquisition of EBP competence.
Determination of the best methods to teach clinical decision-making has been made difficult by the lack of well-validated evaluation tools and the absence of randomized controlled trials evaluating the impact of EBP educational interventions . In addition, assessment tools used to assess EBP competence have primarily focussed on medical students and graduates [9, 10]. A systematic review  identified 104 unique instruments, most of which were administered to medical students and postgraduate trainees and evaluated EBP skills. That paper identified that the majority of instruments predominantly focused only on one aspect of EBP (critical appraisal).
At nursing area the published questionnaires are used to evaluate self perceived competency in EBP for registered nurses. One of this, the Evidence Based Practice Questionnaire (EBPQ)  focuses on research utilization, in particular nurses’ ability to access and appraise research reports and implement research findings in practice. Several other questionnaires have been adapted from medical context. One of them is the questionnaire adapted by Watters et al.  from the McColl et al.  Evidence Based Medicine instrument. Watters et al. didn’t mention the reliability and validity results from the questionnaire adaptation. Other example of the use of medicine instruments to study the EBP in nursing is the one written by Brown et al.  based in the Johnston et al.  “KAB Questionnaire”. In this case, it was focused in United Stated nursing students from different academic years, and the authors didn’t make any adaptation of the items to the nursing context.
Very few reports have looked at the undergraduate learning environment, even less in nursing context. A growing body of literature exploring EBP teaching and learning confirms the research deficit in undergraduate EBP education and calls for further work within this area. Waters et al.  adapted the Nurses Perceptions of Evidence- based Practice survey for student attending post-registration education courses at a professional nursing college. Brown et al.  adapted the questionnaire developed for undergraduate medicine students by Johnston et al.  to nursing students. To conclude: assessing EBP competence in nursing students is hampered by a relative shortage of validated and practical assessment tools.
In Spanish nursing area we only found two questionnaires related to the EBP. One is the translation of the EBPQ  and the other one has been originally developed in Spanish . However, any of these have been created specifically for the assessment of undergraduate nursing student’s competence in EBP.
From this review of the literature and published instruments, there appeared to be a need for a knowledge, attitude and behaviour questionnaire designed to evaluate EBP teaching and learning in an undergraduate nursing curriculum in Spanish. However, concepts like attitude and behaviour need to be measure with self-perceived questionnaires. For the reason that undergraduate nursing students’ competence in EBP appear to be important in determining the future behaviour and use of EBP  and because existing instruments may be less than satisfactory for measuring these attributes. For the purpose of this study, competence is defined as the capability to choose and use an integrated combination of knowledge, skills and attitudes with the intention to develop a task in a certain context .
The purpose of the study was to develop and validate a new measure, the Evidence-based Practice Competence Questionnaire (EBP-COQ), an instrument to assess undergraduate nursing students’ attitude, knowledge and skills in EBP in a Spanish context.
The development and validation of the EBP-COQ occurred in three phases. The first phase consisted of the identification of items for the questionnaire, the second phase involved a pilot test of the first version of the instrument, and the final phase comprised the processes used to psychometrically evaluate the questionnaire administering in our target population, undergraduate nursing students. The steps followed for the instrument’s development used guidelines and methodologies .

For the second step in this phase, two focus groups were carried out in order to develop the items. This method allowed us to explore and identify relevant aspects of EBP for nursing students. We also extracted words and expressions that could be useful for refining and creating items on the questionnaire. The students were selected to maximize sample variation on criteria judged as likely to influence competence in EBP. The first group consisted of undergraduate nursing students who had studied EBP in their nursing programme as an optional course (n = 8) and the second consisted of nursing students who had not studied this matter (n = 8). A question guide was created to facilitate the discussion and to explore student opinions about their previous experience with EBP and their attitude toward its use and learning.
After the literature review and the focus groups a large pool of statements was prepared to be sure that there was an adequate sample of items within each of the three major content areas comprising the competence construct: attitude, knowledge and skills. The items were re-phrased into affirmative statements and asked the respondents to rate their self perception of competence in EBP using a 5-point Likert-type scale, ranging from 1 “Strongly disagree” to 5 “Strongly agree”. Each area of content was represented by equal numbers of positive and negative exemplars of the construct, a condition that tends to reduce subsequent error due to acquiescence. A pool of 110 potential items formed the first questionnaire version.
The selection of the items was carried out in two stages. In the first stage six experts in EBP were asked to classify the items into one of three dimensions that were part of the competence construct (attitude, knowledge and skills). The items which achieved an agreement level of less than 75% or raised doubts about their inclusion in one dimension or other were eliminated. For example, the item “I wish to be updated in the EBP implementation” was removed. A total of 28 items were eliminated, all of them from the attitude dimension. In a second stage the experts also evaluated the level of relevance of each item for its corresponding dimension of competence in EBP. The items were classified according to three categories: 3 “essential”, 2 “interesting but not essential” and 1 “irrelevant”. The statistical mean for each item was calculated and those, which had a mean over 2.5, were kept on the scale (relevance of 83.3%). The following version of the questionnaire was reduced to 62 items in a proportion that was the equivalent of items edited in a positive and negative sense.
In addition, 20 undergraduate nursing students were selected in order to assess the comprehension and feasibility of the reviewed pool of items and format response. They were selected with a socio-demographic and work profile that was similar to that of the study population.
The second phase and after modifying the items according the nursing students’ suggestions we administered the first draft of the EBP-COQ (62 items) to a convenience sample of second and third year nursing students enrolled at Faculty of Nursing in Spain. The day that the instrument was administered 148 students attended to class and 100 of them completed the questionnaire. The aims of this were to evaluate the quality of generated items and eliminate those proving to be inadequate.
Description of the questionnaire
To collect more information and to use it for ulterior analyses we designed an instrument with 4 sections. The first section asked respondent to describe their personal and college characteristics, including age, gender, academic level, other degrees (Diploma, Bachelor, Master or PhD.), any extra training in EBP and nursing research carried out in the last 3 years, and number of journals that they had read in the last month. The next section was the EBP-COQ. A subscale of five items from the “Attitude to Research Scale”  was added as the third section. The last section explored the general attitude toward EBP, knowledge and skills in EBP, English language, statistic and computer practice measured on 10-point visual analogue scales. The objective of these 2 last sections was to facilitate the checking of the external construct validity of the questionnaire.
In phase three, the final version of the questionnaire was administered to undergraduate nursing students in November of 2009. The target population for this study was undergraduated nursing students from the Faculty of Nursing, University of Murcia. The convenience sample consisted of baccalaureate nursing students from second and third year (n = 325).
The study was approved by the Research Ethics Committee at University of Murcia. A participant information sheet giving details of the study accompanied the questionnaire. The consent to participate in the survey was personally asked to each student and confidence was assured.
Student participants were informed that participating or declining participation at the study would not affect grading, class standing, or further opportunities at the university.
For the focus groups, all references to EBP competence were coded by two researches. Each researcher made a thematic analysis of the data, and coded them for quite specific concepts of EBP that has been extracted from the literature (believes, feelings, knowledge, implementation, usefulness, practice). A consensus was reached by checking the concepts and themes in relation to the coded extracts and the entire data set.
For the questionnaire, analyses were performed using SPSS version 17. Frequencies of all responses were reviewed for outliers and non-normality. Continuous variables were described using distribution, and ranges. X2 tests were used to compare competence in EBP at categorical variables (gender, previous training in EBP, etc). Student’s t test, analysis of variance testing, and correlation coefficients were used to compare competence in EBP and continuous variables (age, integration of research at work scale, visual analogue scales, etc…).
Cronbach’s alpha was used to quantify the internal reliability of the total questionnaire and the 3 factors, and to assess the contribution of each question to the overall reliability of each factor. Content validity was addressed through the instrument development process, both by basing the items on the prior instruments and by collegial development of the new items using a panel experienced in EBP.
Construct validity was carried out using pairwise deletion of missing values and conducting a principal components factor analysis with orthogonal varimax rotation for each item set. The sorted factor loadings, eigen values and scree plots resulting from these analyses were examined to identify the number of dimensions or factors that made up the best solution for each item set. We examined the factor loadings to determine whether all items in the set were associated with the attribute of interest. Items with a factor loading less than 0.40 were deleted.
External construct validity was also explored by examination of correlations between the attributes and other characteristics of the respondents as measured by selected other items of the survey. Specifically, we hypothesized that the competence in EBP should be highly intercorrelated with attitude to research, whereas the other attributes (previous training in EBP and Nursing Research) should be only modestly intercorrelated. In the special case of the visual analogue scale set addressing self-perception of attitude toward EBP, knowledge in English, biostatistic, etc were hypothesized to modestly intercorrelated with the EBP-COQ. Criterion-related validity was not addressed explicitly in this study.
Items development and selection has been explained in the Method section. In this section, we report the results of the pilot administration and the final validation of the EBP-COQ to the target population.
The sample population of undergraduate nursing students (n = 100) completed a pilot administration of the 62-item EBP-COQ. Cronbach’s alpha coefficient for the first administration was 0.881. Through an item analysis we discarded those items that were either highly correlated with other items, and were thus considered repetitive, or that had item-scale correlations less than 0.30. Eventually, with the reduction of these items a definitive scale was obtained to assess competence in EBP consisting of 32 items.

As indicated previously, content validity for the item sets was addressed by grounding the questionnaire development in an earlier survey instruments, focus groups and in the development of the form with guidance from an expert panel.
During several steps, a total of seven items were eliminated because they did not contribute to a simple factor structure and failed to meet a minimum criteria of having a primary factor loading of 0.4 or above, and no cross-loading of 0.3 or above. For example, the item “I did not know the main healthcare bibliographic databases where I can search scientific information (Medline, Embase, Lilacs, CINALH, etc…)” did not load above 0.3 on any factor.
Finally, the factorability of the 25 items was examined. Several well-recognised criteria for the factorability of a correlation were used. Firstly, the 25 items correlated at least 0.3 with at least one other item, suggesting reasonable factorability. Secondly, the Kaiser–Meyer–Olkin measure of sampling adequacy was 0.933 (p < 0.001), suggesting that factor analysis was appropriate for this data set. Barlett’s test of sphericity was significant (χ2 (300) = 3037.995, p < 0.001). The diagonals of the anti-image correlation matrix were all over 0.5, supporting the inclusion of each item in the factor analysis. Finally, the communalities were all above 0.3 further confirming that each item shared some common variance with other items. Given these overall indicators, factor analysis was conducted with all 25 items.

This paper described the development and psychometric evaluation of a questionnaire designed to explore nursing undergraduate students’ self-perceived competence in EBP. It consists of 25 items, which are organized into three subscales (attitudes towards EBP, skills and knowledge of EBP). All items of the instrument are scored on a Likert-type scale of 1- 5, with a higher score indicating more self-perceived competence in EBP, greater self-perception of knowledge and skills in EBP, and more positive attitudes towards the EBP. Cronbach’s alpha measured 0.88 for the entire questionnaire, demonstrating internal consistency.
Although the instrument is focused in nursing undergraduate students, the selection of the content included in the questionnaire was based on both, relevant literature, professional experts and nursing students, in order not to omit most important issues. These procedures, in addition with theoretical definition of the constructed covered by the instrument, and with experts review over items, contributed to support the face validity . Construct validity was established through the demonstration of convergent and discriminant validity.
Criterion validity has not been measured as an agreement in terms of responses collected from a gold standard questionnaire. At the moment that the study was carried out, any Spanish gold standard was known. However, discriminant validity was aimed at examining the ability of the EBP-COQ to distinguish between groups so that it should theoretically be able to distinguish between those nursing students with previous knowledge of EBN and those without. On the other hand, the correlation between attitude towards research and the self perception of knowledge, skills and attitude measured through the analogue visual scales and EBP-COQ scores suggested that the questionnaire was measuring competency in EBP.
As similar publications aren’t available at this point, this work posts a contribution to the educational research. The Sicily Consensus Statement on EBP [7, 29] high- lighted a need for effective training in each of the five steps of EBP, and future research into valid and reliable instruments to evaluate this training. The present questionnaire could be a useful measure to evaluate the programmatic impact of EBP educational interventions in nursing area. Educators might turn to instruments with strong evidence of responsive validity in order to recommend appropriate educational and organizational interventions. This could contribute to reduce the lack of consensus as to the best teaching and learning methods for integrating EBP into an undergraduate-nursing curriculum.
The choice of an EBP evaluation instrument should be guided by the purpose of the evaluation and the EBP domains of interest. Future users of the questionnaire should be into account that the definition of the EBP competence by the Tuning Nursing Project  and the technical statements from the Nursing Curricula has oriented the scope of its content.
As previously mentioned other authors have developed questionnaires with the aim to evaluate EBP in health related professions [5, 11, 31]. One example of it is the KAB questionnaire, one of the most referenced instruments in this context. Johnston et al.  designed the “KAB” questionnaire with a result of a 50, 7% of the variance. The Cronbach’s alpha of each of the factors of Johnston et al questionnaire were between 0,75 to 0,88. If we compare these statistical results with the EBP-COQ ones, we can highlight the relevance of the EBP-COQ instrument.
A crucial characteristic of the EBP-COQ is the self-perceived method of assessment. The intention was to use an approach that allows assessing the subject’s attitude, one of the three components of the competence construct. This is one of the most important differences from other traditional instruments that hardly assess this domain in depth because of the difficulty to assess behavioural issues through objective measures. However, previous studies have been able to demonstrate the importance of this dimension as a predictor of a positive behavioral toward resource utilization after following educational interventions [7, 32].
On the other hand, the use of objective or self-perceived instruments to measure knowledge and skills depends on the research aims and both of them could be complementary. McCluskey and Lovarini  have showed that objective and self-perceived instruments found similar results in a pre-post test educational intervention addressing in a sample of occupational therapists.
In addition, the self-perceived method is the most useful to way to measure the competence in EBP even before the students receive the training, or it could be used with the same group of participants (e.g. pre and post EBP training). This solves one of the issues concerning development of EBP evaluation instruments whether the instrument is intended for repeated use . As McCluskey and Lovarini  suggest a limitation of the objective measure instruments is the possibility of a learning effect from repeated administration of the outcome measures. Repeated administration of measures, particularly those focusing on knowledge, may have over-estimated the treatment effect.
The EBP-COQ instrument assesses the self-perceived competence level in EBP. The instrument has demonstrated very good reliability, and the validity findings show promise in the application of the instrument for evaluating change due to education at an undergraduate nursing level.
In contrast to other EBP assessment instruments that focus primarily on comprehension of concepts, the EBP-COQ provides information about the effects of training in three domains: attitudes, knowledge and skills. Overall, the EBP-COQ demonstrates good sensitivity to the effects of training, distinguishes among respondents with different educational training in EBP and research methodology, has good reliability and has strong internal consistency when the instrument is considered as a whole, across three dimensions.
The self-report and multiple-choice design ensured the use of the instrument as reflected in the short completion times. The instrument is applicable to classroom settings, workshops, seminars, faculty retreats, and online administration.
Future steps of this research could be focused on a confirmatory factor analysis of the preliminary questionnaire version presented here, in other Spanish representative sample, or even in other Spanish language countries. These researches could explore additional evidences of validity based in construct, convergent and criterion indicators.
