Detachment scores on the Karolinska Scales of Personality correlated negatively with [18F]CFT binding in the putamen (r=–0.43, df=15, p<0.05), especially in the right hemisphere (F1) (r=–0.36, df=15, p<0.12, in the left putamen). This correlation remained significant in the right putamen also after T-score transformation of the personality data (r=–0.44, df=15, p<0.05). No other personality scores correlated with [18F]CFT binding in the striatum, except social desirability, which correlated positively with [18F]CFT binding in the putamen (r=0.61, df=15, p=0.009), especially in the right hemisphere (r=0.68, df=15, p=0.003, in the right putamen, r=0.47, df=15, p<0.06, in the left putamen, T-score transformed data). However, there was a highly significant negative correlation between social desirability and detachment subscales (r=–0.73, df=15, p=0.001). In the caudate, no correlation was observed between [18F]CFT binding and the detachment score (r=–0.27, df=15, p<0.21, for the right caudate, r=–0.21, df=15, p<0.35, for the left caudate) or any other of the personality scores.
