* p ≤ .05, ** p ≤ .01, *** p ≤ .001
aPlease note that the numbers of participants included in the analyses are slightly lower than the numbers reported in the participant section as for these analyses only those individuals were included who had completed self- and other-report
bPlease note that self-reported AQ scores are lower than in Table 2 as 10 items are omitted for the comparison with other-report (see “Methods” for details)
