Multiple linear regression of factors associated with pregnant women perceiving benefit in disclosure of prenatal mental health problems.

Variablea	B (95% CI)	Standard error	Beta	P value	Partial eta squaredb
Age (under 25 years)	−.77 (−1.68 to 0.15)	0.47	−.07	.10	0.004
Parity (first child)	.21 (−0.49 to 0.90)	0.35	.02	.56	0.001

^aIndependent variables with P<.20 were entered simultaneously into the final model, including maternal age and parity. The supplementary table of the univariate analysis is available from the corresponding author.

^bOn the basis of guidelines [32], a partial eta squared of >0.01 is a small effect size, >0.06 is medium, and >0.14 is large.
