The goal of this clinical trial is to evaluate whether a culturally tailored decision aid can improve decision-making and clinical outcomes for Taiwanese women considering elective egg freezing.
The main questions it aims to answer are:
Does the decision aid improve women's knowledge about elective egg freezing and help clarify their personal values? Does the decision aid reduce decision regret and psychological distress after making a decision about egg freezing?
Researchers will compare women who use the decision aid with those who receive standard counseling to see if the tool improves knowledge, reduces distress and regret, and leads to better clinical outcomes (such as completing egg freezing or achieving a higher number of frozen oocytes).
Participants will:
* Complete questionnaires assessing their baseline knowledge, attitudes, and values regarding egg freezing * Receive either the decision aid or standard counseling * Complete follow-up questionnaires to assess knowledge, distress, and decision regret * Have their clinical outcomes recorded, including whether they undergo egg freezing and the number of oocytes retrieved and frozen

elective egg freezing decision aid
Other interventionThe EEF decision aid used in this study is an evidence-based educational tool designed to support shared decision making. Its primary function is to provide clear, balanced, and structured information to help women make decisions that align with their personal values and reproductive goals.
Decision Regret Scale
The Decision Regret Scale (DRS) is a 5-item validated questionnaire used to assess distress or remorse after a healthcare decision. Each item is scored on a 5-point Likert scale. Scores are transformed to a 0-100 scale, with higher scores indicating greater decision regret (worse outcome).
Knowledge score regarding elective egg freezing
Knowledge regarding elective egg freezing will be assessed using a self-developed questionnaire consisting of multiple-choice items covering fertility decline, success rates, risks, and procedural aspects. Each correct answer is awarded 1 point. Scores are transformed to a 0-100 scale, with higher scores indicating greater knowledge (better outcome).
Decisional conflict scale
The Decisional Conflict Scale (DCS) is a 16-item validated instrument measuring personal perceptions of uncertainty in choosing options, modifiable factors contributing to uncertainty, and perceived effective decision-making. Each item is scored on a 5-point Likert scale. Scores are converted to a 0-100 scale, with higher scores indicating greater decisional conflict (worse outcome).
Depression anxiety stress scale
The Depression Anxiety Stress Scales-21 (DASS-21) is a 21-item validated questionnaire assessing symptoms of depression, anxiety, and stress across three subscales. Each item is scored from 0 to 3. Subscale scores range from 0 to 21 (or 0-42 after standard multiplication), with higher scores indicating greater psychological distress (worse outcome).
Elective egg freezing treatment completion rate
Treatment completion is defined as participants who undergo at least one completed oocyte retrieval cycle for elective egg freezing following enrollment. The completion rate will be calculated as the proportion of participants who complete treatment out of all enrolled participants.
Elective egg freezing attitudes and expectations (qualitative assessment)
Participants' attitudes, expectations, and reproductive planning regarding elective egg freezing will be assessed using investigator-developed open-ended questions. Responses will be analyzed using qualitative content analysis to identify key themes related to decision-making, perceived benefits and concerns, and future reproductive intentions.
