Stress management practices score at survey 2	1,874	1.66 [1.62, 1.70]	1.61 [1.54, 1.67]	0.19
Pregnancy-Related Empowerment score at survey 2	1,876	2.48 [2.45, 2.51]	2.42 [2.36, 2.47]	0.10

Note. CA ITT = contamination adjusted intent to treat effect. Scale used for each measure: prenatal distress = updated Prenatal Distress Questionnaire (NUPDQ); prenatal anxiety = Pregnancy Specific Anxiety Scale (PSAS); prenatal depression = Center for Epidemiological Studies Depression Scale (CES-D) Scale; use of coping strategies = Revised Prenatal Coping Inventory (R-PCI) Scale; stress anagement practices score = Health Promoting Lifestyle Profile II; pregnancy empowerment score = Pregnancy-Related Empowerment Scale. Each sub analysis included the entire analytic sample (see Table 3 for n associated with each measure); the n in Table 4 represents the number of participants in each subgroup.
