Introduction
Measuring
women’s experiences of childbirth can be achieved using a valid and reliable instrument.
For this purpose a psychometric scale called the 10-item-Birth-Satisfaction-Scale-Revised (10-item-BSS-R) has been developed. Two versions of the scale are now available for use
in projects intended to evaluate childbearing women’s experiences of childbirth:
(1) The psychometrically robust, valid and reliable 10-item-BSS-R from which scores can be correlated with other
validated measures (e.g., pain, depression, self-efficacy scales).
(2)
The qualitative 30-item-Birth-Satisfaction-Scale-Long-Form
(30-item-BSS-LF) designed to assess individual
women’s experiences for purpose of debriefing, before counselling or prior to in-depth
qualitative work.
What
is birth satisfaction?
Every woman constructs
expectations of childbirth with variation in appreciating the concept. Literature
supports that birth satisfaction includes:
•
having one’s
comfort considered
•
being listened
too
•
receiving the type
of pain relief requested
•
coping well during
labour
•
feeling in
control
•
being well-prepared
•
receiving
minimal obstetric injuries
•
achieving the
desired style of delivery
Within the confines of
safety, birth satisfaction is about attempting to provide women with what they want
during labour. Three overarching themes identified in the literature are
important when measuring birth satisfaction:
(1)
Quality of care provision
(2)
Personal attributes
(3)
Stress experienced during
labour
These 3 themes
are divided into sub-themes that underpin the questions asked on the 30-item-BSS-LF

Qualitative validation of the
themes and sub-themes that underpin the 30-item-BSS-LF
was carried out using a research method called concurrent analysis.

Evaluation of key psychometric properties of the 30-item-BSS-LF
For the purpose of psychometric testing of statements on the 30-item-BSS-LF, a quantitative survey
was carried out at Ayrshire Maternity Unit (AMU) in Kilmarnock (West of
Scotland, UK). Participants included a convenience sample of
women (n=228) <10 days post-delivery. Key psychometric properties
of the 30-item-BSS-LF were evaluated using
Exploratory Factor Analysis (EFA) and Structural Equation Modelling techniques
(SEM).
Post
psychometric analysis of the items on the 30-item-BSS-LF,
the scale was reconfigured into the 10-item-BSS-R,
which comprises 3 sub-scales that
measure distinct but correlated domains of: (1) quality
of care provision (4-items), (2) women’s personal attributes (2-items), and (3) stress experienced
during labour (4-items).

Conclusion
The validated 10-item-BSS-R
is a robust questionnaire that can be used to measure birth satisfaction post
birth. The
BSS can be used to collect data both nationally and internationally, with
results potentially correlated with other validated measures. In contrast, the 30-item-BSS-LF
may be used to assess individual women’s views of their birth experience prior
to counselling or in-depth qualitative work. If you would like to
use either scale please contact: c.j.hollins-martin@salford.ac.uk.
The first author would be interested in working with researchers who are
willing to translate the scale into other languages to make it available for
wider use.
