Psychometric properties of the Chinese version of the Perinatal Bereavement Care Confidence Scale (C-PBCCS) in...

The Perinatal Bereavement Care Confidence Scale (PBCCS) was designed to evaluate midwives' and nurses' confidence and its psychosocial factors to provide bereavement care in Ireland. However, it is unknown whether this scale is valid and reliable for use with midwives and nurses in China. The aim of this study was to translate the English version into Chinese (C-PBCCS) and determine its validity and reliability in a population of Chinese midwives and nurses.

In this cross-sectional observational study, after translating the English version of the PBCCS into Chinese and ensuring the linguistic adequacy and clarity of the language, we evaluated the validity and reliability of the C-PBCCS with Chinese midwives and nurses (n = 608). Participants were recruited using convenience sampling from 10 maternity hospitals in Zhejiang and Jiangsu Provinces. Exploratory factor analysis (EFA) was conducted to determine the construct validity (n = 304). Another sample of 304 midwives and nurses was used for confirmatory factor analysis (CFA) to verify the quality of the factor structures. Cronbach's alpha coefficient and Guttman split-half coefficient were adopted for the evaluation of internal consistency. The STROBE was followed in reporting the results.

The 43-item PBCCS was reduced to 40 items. Bereavement support knowledge (13 items, three factors), Bereavement support skills (eight items, two factors), Self-awareness (eight items, two factors), and Organizational support (11 items, two factors). The CFA suggested that the four scales in the C-PBCCS had acceptable fit indices. The Cronbach's alpha ranged from 0.835-0.901. The Guttman split-half coefficient was between 0.868-0.933.

The C-PBCCS was found to be a psychometrically sound measurement tool to evaluate Chinese-speaking midwives' and nurses' confidence and the psychosocial factors that affect their confidence in providing perinatal bereavement care.
