Objective

Few studies have tested cognitive behavioral therapy to reduce prenatal anxiety despite substantial empirical support among individuals seeking treatment for anxiety symptoms. We examined whether a brief cognitive behavioral intervention delivered to low-income pregnant women would be efficacious for reducing prenatal anxiety.

Method

A sample of 100 primarily ethnic and racial minority pregnant women with subclinical anxiety (74% Latina, 18% Black; M_age = 26.5) were randomized to an 8-week cognitive behavioral stress management (CBSM) intervention (n = 55), or to an attentional control condition (n = 45). Two forms of anxiety (state and pregnancy-specific) were measured at baseline, post-treatment, and at follow-up in the postpartum using the State-Trait Personality Inventory-State and the Pregnancy Related Anxiety scale, respectively. Intent-to-treat (ITT) and completer analyses were conducted using linear mixed models to test mean differences in both forms of anxiety by group assignment and by intervention completion (< 7 vs. ≥ 7 sessions) at post-treatment and follow-up timepoints.

Results

ITT results revealed no intervention Group × Time interactions for state, F(3, 356) = .51, p = .68, or pregnancy-specific anxiety, F(2, 184.39) = .75, p = .47, indicating no intervention effect post-treatment or at follow-up. Completer analyses showed that women who received all intervention content (34.5%) had significantly less state anxiety at post-treatment compared to women who had not completed the intervention, (65.5%; M_sessions = 3.62); F(6, 270.67) = 2.35, p = .03, and those in the control condition.

Conclusions

While we did not find support for the use of CBSM to treat prenatal anxiety among low-income women, those who received a full dose benefited in state anxiety immediately postintervention. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
