A Rasch-based dimension of delivery experience: spontaneous vs. medically assisted conception.

AIMS AND OBJECTIVES: To devise a set of indices representative of a latent dimension of delivery perception, aimed at the assessment of birth experience after both spontaneous and medically assisted conception. BACKGROUND: Birth experience is of great importance for its prognostic value for the woman and newborn's psychophysical well-being, especially after the experience of assisted reproduction technology. Up to date, a delivery perception assessment measure targeted to both spontaneously and medically assisted conceiving women does not exist yet. DESIGN: Measure development and psychometric analysis; quantitative and qualitative analysis of women's delivery experience measures. METHODS: Thirty-one indices characterising seven relevant aspects of birth perception were devised from the literature and evaluated on a 4-point Likert-type scale by 98 childbearing women (54 spontaneously and 44 medically assisted conceiving) in the 24-48 hours postpartum time frame. Women's obstetric history information was also collected. The dimension psychometric definition was pursued within a latent trait perspective, by applying the many-facet Rasch measurement model. RESULTS: A latent delivery perception dimension composed of 18 valid and reliable indices, qualifying six labour and delivery perception clinical aspects, was identified. Medically assisted conceiving women evidenced a more positive birth perception, but when analysing each index, they showed peculiar intense worries about themselves and their baby's health, even if they felt more satisfied, safer and stronger in almost every labour and birth aspect. CONCLUSIONS: The delivery perception dimension integrates all relevant birth experience aspects in 18 easy-to-administer indices and provides a valid, reliable and feasible assessment tool for both the clinical practice and research purposes. RELEVANCE TO CLINICAL PRACTICE: The delivery perception dimension clearly discriminates between women's types of conception and identifies relevant differences in their birth experience, which are interesting for their clinical implications within a prognostic and intervention perspective of support provision in the early postpartum period.

Assessing the perception of the childbirth experience in Italian women: a contribution to the adaptation of the Childbirth Perception Questionnaire.

BACKGROUND: childbirth is a crucial experience in women's life as it has a substantial psychological, emotional and physical impact. A childbirth positive experience is important to the woman, infant's health and well-being, and mother-infant relationship. Furthermore, it is useful for the care providers to guarantee the best preparation, health service and support to childbearing women. The Childbirth Perception Questionnaire (CPQ) is a 27-item instrument designed to assess women's perception of their childbirth experience. OBJECTIVES: to provide a first attempt to adapt the Childbirth Perception Questionnaire (CPQ) using a sample of Italian women. The psychometric properties of the scale and the quality of women's childbirth experience perception were assessed. Furthermore, the potential relation between the childbirth perception and the pain perception was explored. DESIGN: two separate studies were conducted. In Study 1, the factor structure and the reliability of the Italian translation of CPQ were assessed. Also a quantitative analysis of respondents' mean ratings was conducted. In Study 2 the relation between the CPQ and the Italian Pain Questionnaire (IPQ) was examined. SETTING: an inpatient gynaecologic-obstetric unit in a university medical centre in Italy. PARTICIPANTS: 195 women in Study 1 and 92 women in Study 2 completed the questionnaires. METHODS: in Study 1 the translated form of CPQ was administered in the 24-48 hours post partum. In Study 2, the participants completed the Italian version of the CPQ and the Italian Pain Questionnaire (IPQ) in the same postpartum time frame. Socio-demographic details and information about women's obstetric history were collected in both Study 1 and Study 2. FINDINGS: an exploratory factor analysis revealed a 24-item scale with a three-factor structure. The Italian version of the questionnaire was labelled Childbirth Experience Perception Scale (CEPS) and composed of three subscales: Labour and Delivery Perception, Control Perception and Change Perception. The questionnaire presented satisfactory internal consistency's indexes both in Study 1 (α coefficients range: .66-.83) and in Study 2 (α coefficients range: .70-.86). The analysis of women's mean scores on CEPS revealed a significant effect of age, social economic status, amniocentesis test, type of childbirth, childbirth preference, and disagreement between actual and preferred childbirth (p<.05). A significant correlation between the CEPS and IPQ scales was found (p<.05). CONCLUSION: the current research evidenced that the Italian first adaptation of the CPQ, the Childbirth Experience Perception Scale, may be a valid and reliable measure of childbirth experience perception for use in different women's health clinical outcome and studies.
