Change in scores	Intercept, coefficient (95% CI)	Response rate, % (95% CI)	Observations, n	Adjusted R²	SE (df)	F test (df)
8-item Patient Health Questionnaire	–2.7 (–4.3 to –1.1)^a	0.01 (–0.01 to 0.04)^b	193	0.003	4.42 (191)	1.66 (1,191)
2-item Generalized Anxiety Disorder Scale	–0.78 (–1.40 to –0.16)^c	0.00 (0.00 to 0.01)^d	193	0.0002	1.67 (191)	1.03 (1,191)
