Multi-Media E-Book for Second-Trimester Termination Due to Fetal Anomaly

1. Study design: The study subjects were couples of obstetric inpatients who would receive termination of pregnancy. Both groups were assessed by the obstetrician in the outpatient clinic who must be admitted to the hospital to terminate the pregnancy. After receiving consent, a pre-test is performed in the clinic. The pre-test included questionnaires (basic attribute, State-Trait Anxiety Inventory (STAI) - the State Anxiety Scale (S-Anxiety), Perinatal Grief Scale (PGS), Beck Depression Inventory). After complete pre-teat, study nurse will provide the experimental group a QR Code to enter the cloud system (Hama Star e-book network platform), enable the couples to read the content at home; the control group receives traditional oral instructions. When the experimental group entered the delivery room, the researcher used the Hama Star e-book network platform to play the content of the termination of pregnancy e-book education model, and discussed the content with them; the control group receives regular traditional education model, with booklet and oral instructions, the intervention is about 20-25 minutes. The experimental group is able to use e-books as needed during induction, hospitalization, and after discharge. Two post-tests are conducted for follow-up. Both groups write the first post-test questionnaire (State-Trait Anxiety Inventory (STAI) - the State Anxiety Scale (S-Anxiety), Perinatal Grief Scale (PGS), Beck Depression Inventory) 60 minutes after education. Then, complete the second post-test questionnaire at the next appointment a month after. 2. Randomization Process: This study used a two-group pre- and post-test mode in experimental design, and random allocation to assign subjects into experimental and control groups. Participants were randomly allocated to the experimental or control group in a 1:1 ratio using the network randomization tool (www.randomizer.org/). 3. Sample size calculation:G-power version 3.1 was used to calculate the required sample size for the study. Set power 0.8, α = 0.05, based on the effectiveness (effect 0.30), the number of samples required for each group in this study is 32, because the tracking period is up to half a year, with a loss rate 50%, the two groups need a total of 96 participants.
