Strain variable	Model 1	Model 2	Model 3	Model 4	Model 5	Model 6
Single parent	1.44 (1.00–2.07)	1.02 (0.66–1.58)	1.37 (0.95–2.00)	1.30 (0.89–1.91)	0.96 (0.61–1.50)	1.23 (0.83–1.81)
Annual household income	–	2.29 (1.38–3.82)	–	–	2.02 (1.20–3.41)	–
Caregiver psychological distress	–	–	1.04 (0.99–1.08)	–	1.03 (0.99–1.07)	1.04 (1.00–1.08)

All models present odds ratios adjusted for age and gender. Annual household income was categorized (<$60 000 and ≥$60 000). Caregiver psychological distress (K6 score) was analyzed as a continuous variable. Ratio of in-home children to adults was categorized (<2:1 and ≥2:1).
