Note: EASE, examination of anomalous self-experiences; ASD, autism spectrum disorder.
aOne item in domain 3 and one in domain 4 are not included in Cronbach’s alpha due to zero variance.
bIndependent samples t-test.
cEqual variances not assumed.
dMann-Whitney U test, significant differences in bold.
