To evaluate the Baby-Act behavioral intervention components by reviewing participants' compliance, knowledge, confidence, goals set, and barriers for achievement.

Baby-Act was a cluster-randomized clinical trial to test a multimodal intervention on healthy feeding practices, physical activity, sedentary behaviors, and sleep among Puerto Rico WIC participants from pregnancy until the first year of life through weekly online lessons, reinforced with weekly text messages and monthly calls. The lessons included knowledge questions, goals (set, met, challenges, and strategies for meeting them), confidence in performing the re--ed activities and their usefulness. Calls asked about confidence and barriers to meeting goals, helpfulness of re--ations, and overall experience. Median (25th, 75th percentiles) or frequencies were used for closed-ended questions; themes were identified for open-ended questions.

Two hundred and seven completed the intervention; 41.3% completed all lessons in pregnancy, 19.0% completed >70% of all lessons (higher for older and more educated mothers, P<.05), and 10% completed at least 70% of calls; however, >50% completed at least 1 lesson/call per topic. Most set/met their goals (>93%) with high confidence, responded correctly the knowledge questions (>61%), read text messages (95.5%), and felt that re--ations were helpful (>98%). Acting consistently helped them reach their goals, and most found the re--ations practical/valuable, with overall high satisfaction.

Most participants highly valued the Baby-Act intervention for its educational content focused on setting and reviewing their weekly goal, a user-friendly platform, and a positive impact on parenting confidence.
