The reliability and validity of the Postpartum Partner Support Scale among Chinese women

The benefits of partner support have been well documented for maternal and child health and wellbeing. Chinese women who practice traditional postpartum rituals may lack support during the confinement and often rely heavily on their partners. Currently, there is no validated measure to assess postpartum partner support in China. To translate the Postpartum Partner Support Scale (PPSS) into Chinese, evaluate its psychometric properties and assess postpartum support among Chinese women. The PPSS was translated into Chinese using a validated process and administered to 428 postpartum women residing in the city of Quanzhou in the Fujian Province in China between September 2021 and July 2022. Reliability analysis demonstrated a Cronbach's α coefficient of 0.97, a split-half coefficient of 0.93, and a retest correlation coefficient of 0.91 (p < 0.01). The item analysis and content validity results fell within the recommended range, with no items requiring deletion. Exploratory factor analysis revealed the extraction of a single common factor, which accounted for 74.05% of the cumulative variance. Confirmatory factor analysis yielded a χ2/df ratio of 1.48 and an RMSEA value of 0.05. Several demographic variables were associated with significantly lower levels of postnatal partner support including older maternal and paternal age, lower maternal education, higher household income, fair relationship with in-law family, female infant sex, and premature birth. The Chinese version of the PPSS exhibited good reliability and validity providing evidence that it may be suitable for evaluating partner support among postpartum women in China.
