Effect of a Social-Support-Based Educational Intervention on COVID-19-Related Anxiety and Perceived Social Support in Pregnant Women: A Randomized Pretest-Posttest Controlled Trial

The goal of this randomized controlled trial is to learn if a spouse-inclusive, social-support-based educational intervention can reduce COVID-19-related anxiety and improve perceived social support in pregnant women during public health emergencies. The main questions it aims to answer are: * Does the intervention reduce COVID-19-related anxiety in pregnant women compared to routine care? * Does the intervention improve perceived social support across its five dimensions (emotional, informational, tangible, affection, and positive social interaction)? Researchers will compare a group of pregnant women and their spouses who receive the seven-session educational program to a control group that receives only routine prenatal care, to see if the intervention reduces anxiety and enhances social support. Participants will: * Attend seven weekly 60-minute face-to-face sessions together with their spouses, which include group discussions, lectures, and Q\&A * Receive supplementary virtual messages (motivational and educational content) between sessions * Complete questionnaires measuring COVID-19 anxiety and perceived social support at three time points: before the intervention, immediately after, and one month later
