DAPP-BQ Scores in Biological Relatives of Schizophrenia Patients by COMT Genotype and Controls for Scales Showing Val108/158 met Polymorphism Effects.

COMT Effect in ANOVA of SCZ-rel SCZ-rel val/val SCZ-rel val/met SCZ-rel met/met Controls All Genotypes
ICC Effect Size partial η2 Raw Score Mean (SD) N=22 Raw Score Mean (SD) N=42 Raw Score Mean (SD) N=18 Raw Score Mean (SD) N=87
Narcissism .07 .13 26.7 (6.42)a,b,c 33.4 (11.9) 36.8 (8.77) 34.8 (9.8)
Rejectionality .001 .10 32.3 (7.82) b,c 35.6 (9.95)d 41.1 (8.94) 37.8 (8.6)
Stimulus Seeking .13 .07 28.1 (7.53)a,c 33.3 (6.92)c 32.6 (7.4)c 38.4 (9.31)

Note: : Each DAPP-BQ scale has 16 items scored on a 5-point scale, with the exception of Suspiciousness and Self-Harm which have 14 and 12 items, respectively.

SCZ-rel=biological relatives of schizophrenia patients, SD=Standard Deviation. η2 represents the effect size of group from ANOVA computation. ICC = intraclass correlation reflecting family-level variance for unconditional mixed-model.

a

SCZ-rel val/val differ from SCZ-rel val/met,

b

SCZ-rel val/val differ from SCZ-rel met/met,

c

Different from controls,

d

SCZ rel val/met differ from SCZ-rel met/met.
