Centrality measures of variables in network structure comparing groups. 1 Betweenness—How well one node connects other nodes (the number of times that a node lies on the shortest path between two other nodes). 2 Closeness—How strongly a node is indirectly connected (average distance from the node to all other nodes in the network). 3 Strength—How strongly a node is directly connected (absolute sum of edge weights connected to a node). 4 Expected influence—the sum of all edges extending from a given node (maintaining the sign). Expected influence computes node strength without taking the absolute value of edge-weights. * 1—never; 2—sometimes; 3—almost every day; 4—every day. ** sum of nuts/dried fruits, fruits, yoghurt. *** sum of cookies, sweet bakery, salty nuts, French fries, popcorn, chips, chocolate, chocolate sweets, ice – cream. **** 0—water; 1—tea; 2—soft drinks/sweetened juices. ***** 1—no, 2—yes
