Eligibility Criteria
PREGNANCY-INDUCED HYPERTENSION, HIGH-RISK PREGNANCY, DISORDERS, PLACENTA PREVIA, PREECLAMPSIA
Heterosexual married couples were recruited from 2 public health care institutions in Singapore based on the following inclusion criteria: (1) both parents were aged ≥21 years, (2) able to read and speak English, (3) had a low-risk pregnancy at >24 weeks of gestation (age of viability in Singapore), and (4) owned a smartphone with internet access. Participants were excluded from the RCT if they were diagnosed with physical or mental disorders that would affect their ability to participate or if they had a high-risk pregnancy (eg, placenta previa major, preeclampsia, or pregnancy-induced hypertension). Those who had a complicated assisted delivery, stillbirth, gave birth to a newborn with congenital issues, or whose infant was admitted to the neonatal intensive care unit were also excluded from the study, as information provided on the SPA might be misleading or unsuitable for them.
