DAPP-BQ Scores in Biological Relatives of Schizophrenia Patients by COMT Genotype and Controls for Scales Showing Val^108/158 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.

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

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

Different from controls,

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