Development and validation of a questionnaire to evaluate the effectiveness of evidence-based practice teaching

Aim The aim of this study was to develop and validate a questionnaire to ev aluate the effectiveness of evidence-based practice (EBP) teaching. Methods The 152 questionnaires completed by health care professionals with a range of EBP experience were used in this study. Cronbach's alpha for the knowledge and attitude questions indicated a satisfactory level of interna l consistency (i.e. >0.60). Results The discriminative validity was evidenced by a statistically signif icant difference in the knowledge and attitude scores of 'novices' (i.e. li ttle or no prior EBP education) compared with 'experts' (i.e. health care p rofessionals and academics currently teaching EBP). Moderate to good (great er than or equal to0.4) sensitivity index scores were observed for both kno wledge and attitude scores as the result of comparing individuals before an d after an EBP intervention. Conclusions The results of this validation study indicate that the develope d questionnaire is a satisfactory tool with which to evaluate the effective ness of EBP teaching interventions.
