The failure to translate evidence into clinical practice has been repeatedly highlighted. This failure is partly attributed to disregarding the context within which healthcare is delivered. The aim of this thesis was to develop and psychometrically evaluate the Context Assessment for Community Health (COACH) tool, and, through that process, provide opportunities to measure aspects of context perceived to be important for Knowledge Translation (KT) interventions in lowand middle-income countries (LMIC). All four studies in this thesis were mainly undertaken in Quang Ninh province, Vietnam during 2008–2014. Study II, however, was also conducted in four other LMICs (Bangladesh, Nicaragua, South Africa, and Uganda). Study I employed inductive content analysis of 16 focus group discussions to explore the influence of context in a community-based facilitation intervention in Vietnam. Studies II and III reported on the development of the COACH tool and assessment of its psychometric properties. Study IV used the COACH tool in a survey among health workers in Vietnam. To date, three sources of evidence regarding validity of the COACH tool have been provided, that is, test content, response processes, and internal instrument structure, with promising psychometric characteristics. The COACH tool could be used as means of characterizing aspects of context ahead of KT interventions, for tailoring KT strategies, and for further understanding of the results of KT interventions.
