Objective: To evaluate changes in appearance-related self-consciousness, anxiety, and psychosocial distress after aesthetic blepharoplasty using the Derriford Appearance Scale-24 (DAS-24), and to determine the effectiveness of a supportive intervention program on psychosocial outcomes.
Methods: A controlled clinical intervention study was conducted on 150 patients undergoing aesthetic blepharoplasty at the Department of Plastic and Reconstructive Surgery, Hanoi Medical University Hospital from December 2023 to February 2025. The intervention group received a standardized care protocol including preoperative counseling and expectation management. Outcomes were assessed using the Derriford Appearance Scale-24 (DAS-24) before treatment, at 1 month, and at 3 months postoperatively. Intervention effectiveness was analyzed using the Difference-in-Differences method.
Results: Before treatment, there was no statistically significant difference in DAS-24 scores between the control and intervention groups (31.9±6.7 vs. 32.5±7.8; p=0.534). At 1 month, the intervention group had lower DAS-24 scores than the control group (26.0±6.0 vs. 29.0±6.9; p=0.001). At 3 months, this difference remained significant, with DAS-24 scores of 23.2±6.1 in the intervention group and 26.2±6.6 in the control group (p=0.0009). The absolute intervention effect estimated by the Difference-in-Differences method was -3.69 points at 1 month and -3.65 points at 3 months. The relative intervention effect reached 129.0% at 1 month and 64.1% at 3 months. No statistically significant associations were observed between DAS-24 improvement and age, sex, education level, marital status, residence, economic status, number of consultations, or blepharoplasty technique.
Conclusion: Aesthetic blepharoplasty significantly improved appearance-related psychosocial distress as measured by the DAS-24 scale. The supportive intervention program involving counseling, postoperative care, and follow-up contributed to greater psychological improvement after treatment.
