|---|---|---|---|
| Primary | The incidence of major postnatal depression in both groups | 6-10 weeks after delivery | Edinburgh Postnatal Depression Scale (EPDS) score\>=13 |
| Primary | The incidence of (clinically significant, probable) postnatal depression in both groups | 6-10 weeks after delivery | Edinburgh Postnatal Depression Scale (EPDS) score\>=10 |
| Secondary | The incidence of acquiring post-delivery persistent pain in both groups | 6-10 weeks after delivery | Pain score\>3 in the perineal, surgical scar or abdomen region that lasts for at least 6 weeks post-delivery |
| Secondary | Pain vulnerability in both groups (1) | Upon recruitment until 6-10 weeks after delivery | Assessment via Pain Catastrophizing Scale (PCS) questionnaire before and after delivery |
| Secondary | Pain vulnerability in both groups (2) | Upon recruitment until 6-10 weeks after delivery | Assessment via Central Sensitisation Inventory (CSI) questionnaire before and after delivery |
| Secondary | Pain vulnerability in both groups (3) | Upon recruitment till end of first stage of labor (1 day) | Assessment via Angle Labor Pain Questionnaire (A-LPQ) during first stage of labor when the participants experience labor pain |
| Secondary | Psychological vulnerability in both groups (1) | Upon recruitment until 5 days after delivery | Assessment via Fear-Avoidance Components Scale (FACS) questionnaire before delivery |
| Secondary | Psychological vulnerability in both groups (2) | Upon recruitment until 5 days after delivery | Assessment via State Trait Anxiety Inventory (STAI) questionnaire before delivery |
| Secondary | Psychological vulnerability in both groups (3) | Upon recruitment until 5 days after delivery | Assessment via Perceived Stress Scale (PSS) questionnaire before delivery |
| Secondary | Pain severity in both groups | During labour till one day after delivery | Pain score\>3 during labour |
| Secondary | Preferences for labor analgesia | Prior to labor and delivery | Recruited patients will be administered a survey on Discrete Choice Experiment (DCE) and other questions on their preferences for labor analgesia. For DCE, nine tasks will be included in which parturients will choose one of four hypothetical forms of labor analgesia: 1) epidural analgesia, 2) pethidine, 3) Entonox (nitrous oxide-oxygen mixture), and 4) no labor analgesia, which varies with regards to six attributes: 1) pain intensity following treatment, 2) duration of second stage of labor, 3) risk of instrumental delivery, 4) risk of back pain, 5) risk of permanent nerve injury, and 6) out-of-pocket cost. |
| Secondary | Preferences for epidural analgesia | Prior to labor and delivery | Recruited patients will be administered a survey on their preferences and opinions on epidural analgesia, including their concerns on possible risk of epidural analgesia e.g. instrumental delivery, prolonged duration of second stage of labor, back pain etc. |
| Secondary | Chinese version of Angle Labor Pain Questionnaire (A-LPQ) | Upon recruitment till end of first stage of labor (1 day) | Assessment via Angle Labor Pain Questionnaire (A-LPQ) during first stage of labor when the participants experience labor pain. The tool comprises 22 items divided into five subscales on the childbirth pain experience: the enormity of the pain, the fear and anxiety, uterine contraction pain, birthing pain, and the back pain/ long haul. Each item is scaled from 0 to 10, implying a range from non to worst possible or extremely (where applicable), and therefore has a total score ranged from 0 to 220. The higher the score, the greater the labor pain. |
