This study aims to evaluate the effect of a guided imagery-based psychoeducational intervention on nausea and vomiting severity and psychological well-being in pregnant women. The intervention includes structured psychoeducation and guided imagery sessions designed to promote relaxation, enhance symptom management, and improve overall well-being. Pregnant women in the first trimester experiencing nausea and vomiting were randomly assigned to either the intervention group or the control group. The intervention group received a four-session guided imagery-based psychoeducation program supported by home-based audio practice, while the control group received routine antenatal care. Outcomes were assessed before and after the intervention using standardized measurement tools.
