The results of stepwise multiple regression analysis of PHQ-9

Positive variables selected	B	SE B	Beta	P-value
Neuroticism score (EPQ)	0.544	0.057	0.43	<0.001
Negative change score of LES	0.250	0.056	0.19	<0.001
Neglect score of CATS	1.310	0.303	0.19	<0.001
Adjusted R2=0.37				<0.001

Notes: B, partial regression coefficient, Beta, standardized partial regression coefficient. Dependent factor, PHQ-9 summary score. Fifteen independent factors: age, sex (female =1, male =0), education years, employment status (unemployed =1, employed =0), marital status (married =1, unmarried =0), living-alone (yes =1, no =0), presence of offspring (yes =1, no =0), comorbidity of physical disease (yes =1, no =0), first-degree relative with psychiatric disease (yes =1, no =0), neglect, punishment, and sexual abuse scores of CATS, EPQ neuroticism score, negative change scores of LES, and positive change scores of LES.

Abbreviations: CATS, Child Abuse and Trauma Scale; EPQ, Eysenck Personality Questionnaire; LES, Life Experiences Survey; PHQ-9, Patient Health Questionnaire-9; SE, standard error.
