Results of Significance Testing Calculated by Comparing the Intra-Community Connectivity of the Individual Communities With Those in Randomized Networks

Study 1 (American sample: n = 201)
Community	1	2	3	4	5	6	7
Node in the community (BNSS item)	1, 3	2	4	5, 6	7, 8	9, 10, 11	12, 13
P value	<.001	<.001	<.001	<.001	<.001	<.001	<.001
Study 2 (Italian sample: n = 912)
Community	1	2	3	4	5	6
Node in the community (BNSS item)	1, 2, 3	4	5, 6	7, 8	9, 10, 11	12, 13
P value	<.001	<.001	<.001	<.001	<.001	<.001

Note: Separation of communities was demonstrated by estimating the distribution of a quality function for randomized networks. Significant P values indicate that each of the communities was significantly larger than communities of the same size detected in randomized networks. Findings suggest that the probability of identifying each community is greater than chance. BNSS items: 1 = intensity of pleasure during activities; 2 = frequency of pleasurable activities; 3 = intensity of expected pleasure from future activities; 4 = lack of normal distress; 5 = asociality behavior; 6 = asociality internal experience; 7 = avolition behavior; 8 = avolition internal experience; 9 = facial expression; 10 = vocal expression; 11 = expressive gestures; 12 = quantity of speech; 13 = spontaneous elaboration.
