    Health professionals are paying increased attention to issues of global health. However, there are no current competency assessment tools appropriate for evaluating their competency in global health. This study aims to assess the validity and reliability of a global health competency survey for different health disciplines. A total of 429 students participated in the Global Health Competency Survey, drawn from family medicine residency, nursing, physiotherapy and occupational therapy programs of five universities in Ontario, Canada. The surveys were evaluated for face and content validity and reliability. Factor analysis was used to identify the main factors to be included in the reliability analysis. Content validity was supported with one floor effect in the "racial/ethnic disparities" variable (36.1%), and few ceiling effects. Seven of the twenty-two variables performed the best (between 34% and 59.6%). For the overall rating score, no participants had floor or ceiling effects. Five factors were identified which accounted for 95% of the variance. Cronbach's alpha was >0.8 indicating that the survey items had good internal consistency and represent a homogeneous construct. The Global Health Competency Survey demonstrated good internal consistency and validity.
