Figure 3. Node Strength Centrality Estimates for the 33 Items in the Social Behavior Questionnaire Completed at Ages 6, 8, and 10 Years.

The R package bootnet was used to estimate the centrality stability coefficient (0.67), which should be above 0.5 to consider the order of the centrality index of the nodes as stable.¹⁹ Item label abbreviations are defined in the Table.
