Fig. 3From: Initial validation of a self-report questionnaire based on the Theoretical Domains Framework: determinants of clinician adoption of a novel colorectal cancer screening strategyCluster dendrogram. The dendrogram shows the hierarchical clustering of the items. The height (indicated by the x-axis) at which any two items/clusters are joined together indicates the closeness between two items/clusters. The shorter the height, the closer the items/clusters are. The dendrogram was derived from a hierarchical agglomerative cluster analysis performed using Ward’s method with squared Euclidean Distance as the distance measureBack to article page
