About this trial
Fear of childbirth ranges from mild worry to severe anxiety and affects women of all ages. It is often linked to perceiving childbirth as unpredictable and painful. Women cope by seeking support, practicing relaxation, or attending prenatal education, with information playing a key role in reducing anxiety and increasing confidence.
Pain neuroscience education has shown benefits in reducing pain, anxiety, and related fears by teaching the neurobiological mechanisms underlying pain.

Treatments tested in this trial
Pain neuroscience education
Other interventionThe patients in the intervention group will receive, in addition to the prenatal educational content, the 12 Pain neuroscience education lessons in audiovisual format. Each lesson will last between 10-15 minutes. The contents of PNE will be an adaptation, focused on the context of a pregnant woman, of the Butler \& Moseley postulates. These contents have already been previously adapted according to the nature of the patients' pain, both in chronic pain and in acute pain. In summary, the participants will receive a detailed explanation about the biopsychosocial component of pain through the use of diagrams, metaphors and practical examples. In turn, the objectives of this program could be summarized as: (1) Reformulate erroneous beliefs about pain, (2) Inform about the biology and protective nature of pain and (3) Provide techniques to reduce kinesiophobia and, consequently, promote physical activity, with the beneficial effect it entails for patients with pain.
Prenatal education
Other interventionThe standard prenatal education is based on the Pregnancy and Postpartum Clinical Practice Guide, consisting of general information about pregnancy (visits and monitoring of pregnancy, diet, phases of delivery, lactation, etc.), as well as specific recommendations for lumbopelvic pain associated with pregnancy. These contents will be developed by midwives from the participating hospitals. Participants will receive 12 educational sessions, with an estimated duration of 10 minutes each.
Treatment groups
Trial outcomes
Primary outcomes
Fear of childbirth
The Wijma Delivery Expectancy Questionnaire (W-DEQ) version A, validated in Spanish, has shown excellent psychometric properties. This instrument consists of 33 items scored from 1 to 6, with higher scores indicating greater fear of childbirth.
Secondary outcomes
Pain catastrophizing
The pain catastrophizing scale is an instrument made up of 13 items (each item scores between 0 and 4), which measures the degree to which patients develop feelings and thoughts related to their nociceptive experience. This scale, which has a validated version for Spanish, shows adequate internal consistency.
Anxiety and depression
The Hospital Anxiety and Depression Scale (HADS) questionnaire will be used. This consists of 14 questions, of which 7 assess symptoms of anxiety (HADS-A) and 7 measure symptoms of depression (HADS-D). Each item scores from 0 to 3, with a score range in each subscale from 0-21. Scores of 0-7 indicate no anxiety or depression; scores between 8-10 indicate medium levels; scores of 11-14 indicate moderate levels and scores of 15-21 indicate severe levels of anxiety or depression. The HADS scale has good internal consistency, reliability, and validity.
