It01 etc: item 1 of the CPRS. Left: matching template of the 6-component structure consisting of 55 nodes. Items were assigned to a single component using a forced-choice filter based on the highest component loadings. Right: the 6-cluster network structure showing an optimal match with the matching template. 1 = member of this component or cluster, blank = not a member. Items that dropped off the network during the incremental pruning procedure or that were discarded from further analyses (it35 and it55, no scores) are shown in [brackets]. Items that were allocated differently by PCA and NCD are shown in bold. See also Figure 3.
