The role of aberrant salience and alexithymia in psychotic experiences of non-treatment-seeking adolescent immigrants compared with natives

Figures & data

Table 1 One-way ANOVA and ANCOVA: effects of immigrant status, ASI, and TAS-20 scores on SPE scores

one-way ANOVA
	Natives (n=75)		Immigrants (n=73)		F(1, 146)	p-Value	95% CI
	M	SD	M	SD			Lower limit		Upper limit
TAS-20	54.40	12.44	63.00	11.31	8.93	0.005	58.18		62.14
SPE	7.75	3.50	9.40	3.65	10.65	0.002	7.97		9.16
ASI	14.25	5.10	16.11	5.19	4.38	0.03	14.32		16.02
ANCOVA
Outcome: SPE	F(1, 145)	p-Value	β	t	p-Value	95% CI		Partial η^2		Observed power
								Lower limit	Upper limit
ASI main effect	18.62	<0.001	0.20	2.58	0.01	0.04	0.36	0.05		0.72
Immigrant status main effect	2.85	0.09	4.70	1.68	0.09	−0.81	10.22	0.02		0.38
Immigrant status * ASI interaction effect	0.72	0.39	0.10	0.85	0.39	−0.13	0.33	0.01		0.13
		Native status * ASI interaction effect	0^a	0^a	0^a	0^a	0^a	0^a		0^a
Native status * TAS-20 interaction effect	4.97	0.02	0.05	1.44	0.15	−0.02	0.12	0.01		0.29
		Immigrant status* TAS-20 interaction effect	0.17	4.60	<0.001	0.09	0.24	0.16		0.99
TAS-20 main effect	18.36	<0.001	0^a	0^a	0^a	0^a	0^a	0^a		0^a

Note: ^aParameter set at 0 because redundant in the model.
