DOC questionnaire: measuring how GPs and medical specialists rate collaboration.
PURPOSE This paper aims to assess the validity of a questionnaire aimed at assessing how general practitioners (GPs) and specialists rate collaboration. DESIGN/METHODOLOGY/APPROACH Primary data were collected in The Netherlands during March to September 2006. A cross sectional study was conducted among 259 GPs and 232 specialists. Participants were randomly selected from The Netherlands Medical Address Book. Specialists rarely contacting a GP were not invited to participate. FINDINGS Exploratory factor analysis indicated that the questionnaire, consisting of 20 items, measured five domains: organisation; communication; professional expertise; image; and knowing each other. Cronbach's alpha coefficients ranged from 0.64 to 0.83 indicating sufficient internal consistency. Correlation coefficients between domains were all 0.4. All but "communication" clearly produced distinguishing scores for different respondent groups. RESEARCH LIMITATIONS/IMPLICATIONS This study shows that the doctors' opinions on collaboration (DOC) questionnaire is valid and that it may have the potential to give feedback to both medical professionals and policy makers. Such feedback creates an opportunity to improve collaboration. ORIGINALITY/VALUE The DOC questionnaire is a useful instrument for assessing collaboration among GPs and specialists. It can provide feedback to both medical professionals and policy makers. Such feedback creates an opportunity to improve collaboration.
