Regressions of BACS subscales with sociodemographic factors and depression score

BACS subscale	Model 1: Variability^* (explained by sociodemographic factors + site)	Model 2: Additional variability^† (explained by adding depression score)	P-value^‡ (explained by depression score)
Geography/Distance^§	10.3%	7.1%	0.0032
Medical and Psychological^¶	1.5%	7.0%	0.0027
Community Stigma^¶	2.2%	7.0%	0.0027
Personal Resources^**	20.9%	17.6%	<0.0001

Variability explained in Model 1 = R² × 100%.

^†

^‡

Significance of additional variability explained by depression in Model 2, after adjusting for sociodemographic factors.

^§

Sociodemographic factors = employment, income, transportation, insurance.
